Essential Ingredients for Your Perfect Chocolate Filled Cookies

Crafting these extraordinary chocolate filled cookies requires a selection of high-quality, yet simple ingredients. Each component plays a crucial role in achieving that signature Levain Bakery-style thickness, softness, and decadent flavor. Here’s a closer look at the key players you’ll need, along with a brief explanation of their importance:

All the essential ingredients meticulously weighed out into small bowls, ready to create delicious chocolate filled cookies.
  • Cornstarch: This seemingly small addition makes a huge difference! Incorporating cornstarch into your cookie dough is the secret to achieving that wonderfully soft, tender, and slightly chewy texture that prevents the cookies from becoming cakey. It truly contributes to the melt-in-your-mouth quality.
  • Butter: For the richest flavor and creamiest texture, I highly recommend using European-style butter, such as Kerrygold. These butters typically have a higher butterfat content compared to standard American butters, which translates to a more luxurious, richer, and distinctly creamy cookie. The butter should be cold and cubed for this recipe, which is a key factor in achieving the desired thick cookie structure.
  • Chocolate Chips (Three Types!): To ensure a truly “chocolate overload” experience, these cookies are generously packed with three different varieties of chocolate chips! We use a combination of semi-sweet chips for classic chocolate flavor, white chocolate chips for a sweet, creamy contrast, and milk chocolate chips for an extra layer of milky richness. This trio creates a dynamic and irresistible chocolatey profile throughout the cookie. Feel free to adjust the ratios or substitute with your favorite baking chips, as long as you maintain the total quantity.
  • Chocolate Hazelnut Spread: This is the heart of our chocolate filled cookies! A generous dollop of delicious chocolate hazelnut spread, like Nutella or your preferred grocery store brand, forms the molten, gooey center. I’ve personally tested this recipe with both Nutella and various store brands. While both deliver a fantastic result, I’ve observed that store-brand versions tend to yield a slightly more melty, liquid-like filling after baking, whereas Nutella often remains a bit firmer in texture. Choose based on your preference for gooeyness!

Step-by-Step Guide to Making Chocolate Filled Cookies

Creating these incredible Levain Bakery-style chocolate filled cookies is a rewarding process. Follow these detailed steps to ensure your cookies turn out perfectly thick, soft, and bursting with gooey chocolate hazelnut deliciousness.

Scoops of chocolate hazelnut spread neatly arranged on parchment paper, next to a bowl of creamed butter and sugar mixture.

Step 1: Prepare the Chocolate Hazelnut Filling. Begin by lining a plate or a small baking sheet with a piece of parchment paper. Using a tablespoon or a small cookie scoop, measure out 8 generous tablespoons of your chosen chocolate hazelnut spread. Arrange these scoops evenly on the parchment paper. Place the plate or sheet into the freezer and chill until the spread is firm, which usually takes about 20-30 minutes. This crucial step prevents the filling from melting out of the cookies too quickly during baking.

Step 2: Cream the Butter and Sugars. In the bowl of a stand mixer fitted with the paddle attachment, or in a large mixing bowl if using a hand mixer, combine the cold, cubed butter with both the white granulated sugar and the light brown sugar. Beat these ingredients together on medium-high speed for a good 3-4 minutes. Continue mixing until the mixture becomes noticeably light in color and achieves a fluffy, airy texture. This aeration is key to the cookie’s final texture.

Step 3: Incorporate the Eggs. Add the cold large eggs to the creamed butter and sugar mixture, one at a time. After each egg addition, beat thoroughly until it is fully incorporated into the dough. It’s highly recommended to pause and use a rubber spatula to scrape down the sides and bottom of the bowl. This ensures all ingredients are evenly mixed, leaving no dry pockets or unmixed portions.

Step 4: Add the Dry Ingredients. Gradually add all the dry ingredients into the wet mixture: the all-purpose flour, baking soda, baking powder, kosher salt, and cornstarch. Mix on a low speed until the dry ingredients are just combined. Be careful not to overmix at this stage, as overmixing can lead to tough cookies due to gluten development.

Step 5: Fold in the Chocolate Chips. Now for the fun part! Add all three types of chocolate chips (white, semi-sweet, and milk chocolate) into the cookie dough in the bowl. This generous amount of mix-ins is crucial for that “chocolate overload” experience.

Step 6: Finish Mixing and Divide the Dough. Gently stir everything together on low speed until the chocolate chips are just evenly distributed. Again, avoid overmixing. Once combined, divide the dough into 8 equal, large cookie dough balls. These are going to be giant cookies! If you find the dough to be too sticky or difficult to handle at this point, transfer the bowl to the refrigerator and chill the dough for 20-30 minutes to help it firm up.

Pro Tip: If your cookie dough feels too sticky or soft after mixing, don’t fret! A quick chill in the fridge for 20-30 minutes will help it firm up, making it much easier to handle and preventing excessive spreading during baking. This is especially useful on warm days or if your butter wasn’t quite cold enough.

Step 7: Stuff the Cookies. Take each cookie dough ball and use your thumbs to create a deep well in its center. Retrieve the frozen chocolate hazelnut spread scoops from the freezer. Place one frozen scoop into the well of each cookie dough ball. Carefully use your fingers to completely encase the chocolate hazelnut ball with cookie dough, sealing it completely. Ensure there are no visible gaps where the filling could escape during baking. If, after handling, your cookie dough feels warm or very soft, place the stuffed cookie dough balls back into the fridge for another 15-20 minutes to firm up.

Step 8: Bake to Perfection. Line two large baking sheets with fresh parchment paper. Place no more than 4 stuffed cookie dough balls on each sheet, ensuring they have ample space to spread without touching. It’s crucial to bake these cookies one sheet at a time to maintain consistent oven temperature and prevent overcrowding, which can lead to uneven baking. Keep the unbaked cookie dough balls in the refrigerator while the first batch bakes. Preheat your oven to a high temperature of 400°Fahrenheit (205°Celsius). Bake for 11-13 minutes, or until the edges are light golden brown and set, but the centers still look slightly soft. Once baked, remove the cookies from the oven and let them cool on the baking sheet for at least 15 minutes. This resting period is absolutely essential for the cookies to firm up and for the gooey chocolate hazelnut filling to set slightly, preventing a molten mess when you bite into them. Patience is key for the ultimate gooey middle!

Mastering Your Chocolate Filled Cookies: Expert Tips & Tricks

Achieving bakery-quality chocolate filled cookies at home is easier than you think with these insider tips and tricks. These pointers will help you perfect your technique and ensure every batch is as delicious as the last.

  • Embrace Your Kitchen Scale: For baking, precision is paramount, and a digital kitchen scale is your best friend. I cannot stress enough the importance of measuring ingredients by weight (the metric way) rather than by volume (cups). It eliminates inconsistencies that can arise from different packing methods and ingredient densities, making a colossal difference to the consistency and success of your bakes. Most of my recipes are developed with metric measurements for this very reason.
  • Achieve That Perfect Bakery Style Look: To give your chocolate filled cookies that professional, perfectly round, Levain Bakery-style appearance, here’s a trick: immediately after taking the cookies out of the oven, use a large biscuit cutter (or an overturned bowl slightly larger than your cookie) to gently “scoot” the warm cookies into a perfect circular shape. The heat allows them to be malleable. For an extra touch of visual appeal and even more chocolate, gently press a few additional chocolate chips onto the tops of each cookie while they’re still warm and soft.
  • Choosing Your Chocolate Hazelnut Spread: The type of chocolate hazelnut spread you use can impact the final texture of your filling. I’ve tested this cookie recipe extensively with both brand-name Nutella and various store-brand versions. My observation is that store-brand chocolate hazelnut spreads tend to result in a much more melty and liquid-like gooey filling after baking. Nutella, on the other hand, often holds its shape a bit more, offering a slightly firmer, yet still soft and decadent, center. Experiment to find your preferred level of gooeyness, or even try other fillings like peanut butter or caramel for a twist!
  • The Power of Cold Butter: Unlike many cookie recipes that call for room temperature butter, this recipe specifically benefits from cold butter. Starting with cold, cubed butter helps create a thicker, chewier cookie that spreads less during baking. The colder fat takes longer to melt, contributing to the cookie’s impressive height and preventing it from becoming flat and overly crisp.
  • Strategic Chilling of the Cookie Dough: The need to chill your cookie dough can vary based on several factors, including your kitchen’s temperature and the initial temperature of your ingredients. If you started with cold butter and your kitchen is cool, you might not need to chill the dough at all. However, during my recipe testing, I found that on warmer days or after extensive handling, the dough can become quite soft and sticky. If this happens, simply place the divided cookie dough balls in the refrigerator for 20-30 minutes. This firming-up period is essential to prevent excessive spreading in the oven and ensures those beautifully thick cookies.
  • The Role of Chocolate Chips: This recipe calls for a substantial amount of chocolate chips, and for good reason! Beyond providing an incredible flavor burst, the mix-ins actually help with the structure of the cookie dough, preventing it from spreading too much and contributing to that desirable thick texture. Feel empowered to customize your chocolate chip selection; swap out any of the three types for dark chocolate, butterscotch, or even chopped nuts! Just ensure you use an equal total amount to maintain the dough’s consistency.
  • Don’t Overmix Dry Ingredients: Once you add the flour mixture, mix only until just combined. Overmixing develops gluten, which can lead to tough, dense cookies instead of the soft, tender ones we’re aiming for.
  • Bake One Sheet at a Time: For consistent results and even baking, always bake only one sheet of cookies at a time in the center rack of your oven. This prevents temperature fluctuations and ensures proper heat circulation around each cookie. Keep any unbaked dough in the refrigerator.
  • Cooling Rack is Key: After the initial cooling period on the baking sheet, transfer your cookies to a wire rack to cool completely. This prevents the bottoms from becoming soggy and allows for even cooling.

Your Top Questions About Chocolate Filled Cookies Answered

Can I make these into smaller chocolate filled cookies?

These particular chocolate filled cookies are specifically designed to be giant, inspired by the generous size of Levain Bakery cookies. Their impressive thickness and gooey center are hallmarks of their large format. If you’re looking for smaller, more traditional chocolate chip cookies, I recommend trying out my chocolate chip pecan cookies, which are scaled for a smaller bite while still being incredibly delicious. Adjusting this specific recipe to a smaller size might alter the bake time and the signature gooey center.

How do I store these chocolate filled cookies?

To maintain their freshness and deliciousness, store these chocolate filled cookies in an airtight container at room temperature. They will remain wonderfully soft for up to 3-4 days. While they are delightful at any time, they are undeniably at their most gooey and irresistible on the first day, especially when slightly warm!

Why do I bake these chocolate stuffed cookies at a high temperature?

I typically bake most of my cookies at 350ºFahrenheit, but for these Levain Bakery-style chocolate stuffed cookies, a higher temperature of 400ºFahrenheit is key to achieving their signature look and texture. Through extensive experimentation, I discovered that baking them at 350ºFahrenheit consistently resulted in flatter cookies. The higher oven temperature for a shorter duration creates a quick crust on the outside, which helps the cookies rise tall and thick, trapping the moisture and creating that perfectly gooey interior without overbaking the edges. It’s a trick that locks in the height and prevents excessive spreading!

What is the best chocolate for cookies?

The “best” chocolate really comes down to personal preference, but generally, for cookies, I find that semi-sweet chocolate or dark chocolate offers the ideal balance. Their slight bitterness helps to perfectly complement and cut through the sweetness of the cookie dough, creating a more complex flavor profile. However, this chocolate filled cookie recipe is incredibly versatile! Feel free to use whatever type of chocolate chips you love most – whether it’s milk chocolate for extra sweetness, white chocolate for a creamy touch, or a mix of all three to achieve a multi-layered chocolate experience.

Can I freeze the raw cookie dough?

Absolutely! Freezing the raw cookie dough is a fantastic way to enjoy freshly baked cookies whenever a craving strikes. After you’ve stuffed the cookie dough balls with the chocolate hazelnut spread, place them on a parchment-lined baking sheet and freeze until solid (about 1-2 hours). Once firm, transfer the frozen dough balls to an airtight freezer-safe bag or container. They can be stored in the freezer for up to 2-3 months. When ready to bake, you can bake them directly from frozen, adding an extra 2-4 minutes to the baking time, or let them sit at room temperature for about 30 minutes before baking as usual.

Why did my chocolate filled cookies spread too much and come out flat?

Several factors can contribute to flat cookies. Firstly, ensure your butter was cold and cubed, not softened or melted. Cold butter helps maintain the cookie’s structure. Secondly, make sure your chocolate hazelnut filling was well-frozen before stuffing; a soft filling can cause the dough to warm up and spread. Thirdly, proper chilling of the dough (especially if it felt sticky) is crucial. A warm dough spreads much faster. Lastly, verify your oven temperature with an oven thermometer. If your oven runs cooler than it indicates, the cookies will bake slower and spread more before setting. Baking one sheet at a time also helps maintain consistent oven temperature.

Ingredients

 

 

  • 8 tablespoons chocolate hazelnut spread
  • ½ cup unsalted butter cold and cubed
  • ¼ cup granulated sugar
  • ¾ cup light brown sugar
  • 2 large eggs cold
  • 2 ¼ cup all purpose flour
  • 1 teaspoon baking soda
  • 2 teaspoons baking powder
  • 1 teaspoon cornstarch
  • 1 teaspoon kosher salt
  • 1 cup white chocolate chips
  • 2 cups semisweet chocolate chips
  • ½ cup milk chocolate chips

Instructions

 

  • Line a baking tray or a large plate with parchment paper. Scoop out 8 tablespoons of chocolate hazelnut spread (Nutella or similar) and place them onto the paper. Transfer the tray/plate to the freezer and chill for at least 30 minutes, or until the scoops are firm. This prevents the filling from melting out during baking.
    8 tablespoons chocolate hazelnut spread
  • Preheat your oven to 400℉/205℃. Line two large baking sheets with parchment paper and set them aside.
  • In the bowl of a stand mixer fitted with the paddle attachment (or using a large bowl and a hand mixer), beat the cold, cubed unsalted butter with the granulated sugar and light brown sugar. Cream these together for 3-4 minutes on medium-high speed until the mixture is light in color and fluffy.
    ½ cup unsalted butter, ¼ cup granulated sugar, ¾ cup light brown sugar
  • Add the cold large eggs one at a time, beating well after each addition until fully incorporated. Use a rubber spatula to scrape down the sides and bottom of the bowl frequently to ensure even mixing.
    2 large eggs
  • Add all the dry ingredients – the all-purpose flour, baking soda, baking powder, cornstarch, and kosher salt – to the bowl. Mix on low speed until they are just combined and no dry streaks of flour remain. Be careful not to overmix.
    2 ¼ cup all purpose flour, 1 teaspoon baking soda, 2 teaspoons baking powder, 1 teaspoon cornstarch, 1 teaspoon kosher salt
  • Add all three types of chocolate chips (white, semi-sweet, and milk chocolate) to the cookie dough. Mix on low speed until they are just evenly distributed throughout the dough.
    1 cup white chocolate chips, 2 cups semisweet chocolate chips, ½ cup milk chocolate chips
  • Divide the dough into 8 large, equal-sized cookie dough balls. If the dough feels too sticky or soft to handle easily, place the balls in the fridge for 20-30 minutes to chill and firm up.
  • Using your thumbs, create a deep well in the middle of each cookie dough ball. Take the firm chocolate hazelnut spread scoops out of the freezer and place one into each well. Use your hands to carefully enclose the frozen chocolate ball completely with cookie dough, sealing it thoroughly. If the dough feels warm after stuffing, place the cookies back in the fridge for 15-20 minutes before baking.
  • Place 4 stuffed cookies on one prepared baking sheet, ensuring plenty of space between them. Bake this sheet in the preheated oven for 11-13 minutes. The cookies are ready when the edges are light golden brown and set, but the centers still appear slightly soft. While one sheet bakes, keep the remaining unbaked cookies chilled in the fridge. Once baked, remove from the oven and let the cookies cool on the baking sheet for at least 15 minutes before handling. This crucial resting time allows them to firm up and for the gooey chocolate hazelnut filling to set properly. Enjoy!

Notes for Success

For best results, my recipes are developed and rigorously tested using metric grams for ingredient measurements. I strongly recommend using a kitchen weighing scale for the utmost accuracy in your baking. While US cup conversions are provided, please be aware that I have not personally tested the recipe using these volume measurements, and consistency may vary. To switch to metric, simply click the ‘Metric’ button above the ingredients list.

Butter: For that exceptionally creamy and rich texture that elevates your finished bake, I consistently use European-style butter, such as Kerrygold, in my recipes. Its higher butterfat content truly makes a difference in flavor and texture.

Salt: If you don’t have kosher salt on hand, be sure to halve the amount of salt specified in the recipe. As a general guideline, 1 teaspoon of Diamond Crystal Kosher Salt is equivalent to approximately ½ teaspoon of fine table salt. It’s important to note that I use Diamond Crystal Kosher Salt; Morton Kosher Salt is a different grind and much saltier, so it’s not recommended for this recipe.

Chocolate Chips: The generous 3.5 cups of chocolate chips are not just for flavor; they also play a crucial role in helping the cookie dough maintain its structure and achieve that desirable thick texture. Feel completely free to customize the mix with your favorite varieties of chocolate chips or even chopped chocolate bars! 

Small Batch: If you’re looking to make a smaller batch, simply halve all the ingredients in the recipe to yield 4 large, delicious cookies. 

Storage: Once baked, store these decadent cookies in an airtight container at room temperature for up to 3-4 days to maintain their softness and flavor. For the ultimate gooey experience, they are best enjoyed on the first day, perhaps warmed slightly!
