This chocolate chip cookie brownie Reese cup recipe delivers the ultimate dessert experience—where every bite combines fudgy brownie layers, crunchy cookie shells, and creamy peanut butter filling in perfect harmony. 💛 The secret lies in baking two distinct components separately before assembling them into individual cups, creating a texture contrast that makes each bite unforgettable.
I developed this recipe after years of perfecting individual elements, ensuring the brownie stays dense and the cookie shell maintains its signature crispness.
The key to success is precision in baking times and temperatures—350°F for both components, but with carefully timed intervals to achieve the right texture. The brownie layer needs to be just set but still moist, while the cookie shells must be golden and crisp enough to hold their shape.
This foolproof method ensures no soggy bottoms or overly dry tops, giving you restaurant-quality results at home.
What you’ll end up with is a dessert that looks as impressive as it tastes—rich chocolate brownie at the base, buttery cookie shells around the edges, and a smooth peanut butter center that ties everything together.
The combination of warm spices in the brownie and classic cookie flavors creates a symphony of textures and tastes that will have everyone asking for seconds.
Perfect for holiday gatherings, dinner parties, or a special treat for loved ones, these Reese cup-inspired desserts are easy to make ahead and even easier to devour. Whether you're a baking novice or a seasoned pro, this recipe delivers professional-quality results with minimal effort. Let’s get started!
Ingredients for chocolate chip cookie brownie reese cup
Twelve ingredients that create a dessert masterpiece—where brownie fudginess meets cookie crunch in perfect harmony.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 cup | White or brown for depth |
| Packed Brown Sugar 🍚 | ½ cup | Light or dark variety |
| Unsalted Butter 🧈 | 1 cup | Room temperature, European preferred |
| Large Eggs 🥚 | 2 whole | Room temperature for even baking |
| Vanilla Extract 🌿 | 1 tbsp | Pure Madagascar preferred |
| Baking Powder 🧂 | ½ tsp | Aluminum-free for best rise |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Chocolate Chips 🍫 | 1 ½ cups | Semi-sweet or milk chocolate |
| Creamy Peanut Butter 🥜 | 1 cup | Natural, no added sugar |
| Dark Chocolate Bars 🍫 | 12 oz | 60% cacao, chopped fine |
| Cocoa Powder 🍫 | ½ cup | Dutch-processed for smoothness |
| Espresso Powder ☕ | 1 tsp | Enhances chocolate flavor |
| Mini Marshmallows 🍬 | 1 cup | For optional extra gooeyness |
| Sea Salt Flakes 🧂 | 1 tsp | For finishing touch |
The butter and chocolate are non-negotiable here. European-style butter (like Plugrá) gives richer flavor, but any good unsalted works. For chocolate, Valrhona or Ghirardelli bars make all the difference—avoid the cheap supermarket brands. The cocoa powder should be Dutch-processed (like Hershey's Special Dark) for that smooth, velvety texture. I always grab mine from Williams Sonoma or Sur La Table—their bulk bins have the best selection. Pro tip: Toast your cocoa powder in the oven for 10 minutes at 300°F to deepen the flavor. Trust me on this one.
No vanilla extract? Vanilla bean paste works perfectly, or even a scraped vanilla bean. Running short on chocolate chips? Chop your own chocolate bars—just melt them slightly first for easier chopping. The peanut butter needs to be creamy and natural—Jif Natural or Smucker's are my go-tos, but any without added sugars works. For the cookie shells, you can use pre-made sugar cookie dough** (like Betty Crocker) if you're in a pinch, but homemade always tastes better. The espresso powder might seem odd, but it intensifies the chocolate flavor without adding coffee taste—just a pinch makes a world of difference.
Store the dry ingredients (flour, sugar, cocoa) in airtight containers for up to 6 months. The butter and peanut butter keep in the fridge for 3 months, while chocolate stays fresh for 1 year in a cool, dark place. Once assembled, these Reese cups keep for 5 days in the fridge or 3 months frozen. For make-ahead magic, bake the brownie and cookie shells separately, then assemble right before serving. The flavors actually improve overnight—perfect for holiday gifting!

Step-by-step instructions for chocolate chip cookie brownie Reese cups
Here's how to create decadent layers of fudgy brownie, cookie crumbles, and peanut butter Reese cups in one bite.
👨🍳 Step 1: Prepare the Brownie Base
Preheat your oven to 350°F and line a 9x13-inch baking pan with parchment paper. In a large mixing bowl, cream together the 1 cup unsalted butter and both sugars until light and fluffy—about 3-4 minutes—using an electric mixer. This step is crucial for creating that perfect fudgy texture.
Add the 2 whole eggs, one at a time, mixing well after each addition. Stir in the 1 tbsp vanilla extract, 1 tsp espresso powder, and 0.5 cup cocoa powder until fully combined. Sift in the 1.5 cups all-purpose flour, 0.5 tsp baking powder, and 0.5 tsp salt—mixing just until the dry ingredients disappear. Fold in 1 cup chocolate chips and spread the batter evenly into the prepared pan.
🍳 Step 2: Create the Peanut Butter Layer
While the brownie bakes, prepare the peanut butter layer. In a small bowl, mix the 1 cup creamy peanut butter with 0.5 cup packed brown sugar and 0.5 tsp salt until smooth. Spread this mixture evenly over the brownie batter, creating a thin layer.
Return the pan to the oven and bake for 20-25 minutes until the edges are set but the center still looks slightly underdone. This ensures a fudgy texture. Let the pan cool completely on a wire rack—this prevents the layers from shifting when you add the cookie crumbles.
🥘 Step 3: Make the Cookie Crumble Topping
In a food processor, pulse the 1 cup mini marshmallows, 0.5 cup chocolate chips, and 1 tsp sea salt flakes until you achieve a coarse crumble texture—about 10-15 seconds. Spread this mixture evenly over the cooled peanut butter layer, pressing down gently to ensure it adheres.
Here's the thing—this crumble topping needs to be firm enough to hold its shape when you cut the bars. If it feels too loose, chill the pan in the refrigerator for 15 minutes to help it set. This step is what transforms your dessert into a textural masterpiece with every bite.
🔪 Step 4: Add the Reese Cup Element
Melt the 12 oz dark chocolate bars in a microwave-safe bowl in 30-second intervals, stirring between each interval until completely smooth. Let the melted chocolate cool slightly for 2 minutes—it should be thick enough to pipe but not set.
Using a piping bag fitted with a small round tip, pipe small circles (about 1-inch diameter) onto the cookie crumble layer, spacing them evenly. Place the pan in the freezer for 10 minutes to allow the chocolate to set completely. This creates those classic Reese cup pockets that make this dessert so irresistible.
⏰ Step 5: Chill and Cut for Perfect Bars
Transfer the pan to the refrigerator and chill for at least 2 hours—this ensures all layers hold together when you cut. The longer it chills, the more distinct each component will be when you slice. Use a sharp knife dipped in hot water between cuts for clean, crisp edges.
Once fully chilled, cut into 12 equal bars and serve at room temperature. Each bite delivers a perfect balance of fudgy brownie, creamy peanut butter, crunchy cookie crumbles, and smooth chocolate—like a Reese cup and cookie brownie had a delicious baby. Trust me, this is the kind of dessert that disappears fast!
Pro Tips For Making Chocolate Chip Cookie Brownie Reese Cup
- MELT THE BUTTER FIRST: Mix the butter and sugars until the bowl looks like a pale, glossy mess—not just streaked. I learned this the hard way: cold butter pockets leave greasy spots in your batter, and those translate to dense, uneven brownie layers. Take the extra 30 seconds to get it smooth.
- WEIGH YOUR FLOUR: Scooping flour from the bag packs it down, adding way more than you need. Spoon it into the scale, then level it off—this recipe lives or dies by the right ratio. Trust me, your Reese cups will be cakey and perfect instead of dry and crumbly.
- UNDERBAKE THE BROWNIE LAYER: Pull the brownie out of the oven when the edges are set but the center still jiggles slightly. It’ll firm up as it cools, and overbaking turns it into a hockey puck. Let it rest 10 minutes before slicing—yes, even if you’re impatient.
- CHILL THE BATTER: Skip this, and your Reese cups will spread like pancakes in the oven. Give the batter 30 minutes in the fridge, and you’ll get clean, defined cups instead of a sad, flat mess. I know, it’s counterintuitive—but it works.
Make-ahead tips for leftovers
Brownie Base Prep
Bake the brownie layer 1-2 days ahead and store it in an airtight container at room temperature. The flavor deepens as it sits, and the texture becomes even more fudgy. I like to wrap it tightly in plastic wrap to prevent drying out.
This step is crucial because the brownie needs time to fully set before adding the peanut butter layer. 💛
Peanut Butter Layer
Prepare the peanut butter mixture 1 day ahead and refrigerate it in a small container. The peanut butter will thicken slightly, making it easier to spread evenly over the brownie.
If it gets too firm, microwave it for 10-15 seconds to soften before spreading. This prepped layer ensures a smooth, creamy texture that pairs perfectly with the brownie.
Cookie Crumble Assembly
Make the cookie crumble topping 1 day before assembly and store it in the fridge. Pulse the marshmallows and chocolate chips together, then press the mixture into a flat disc.
Wrap it tightly in plastic wrap and chill until ready to use. This pre-chilled crumble adheres better to the peanut butter layer, creating a cohesive texture when sliced. 🥜
Reese Cup Chocolate
Melt the dark chocolate for the Reese cup element just before assembly—it sets quickly. Pipe the circles onto the crumble layer and freeze for 10 minutes to firm up. Store the assembled pan in the freezer for up to 1 month if making ahead.
The chocolate stays glossy and snaps cleanly when chilled, giving you that perfect Reese cup experience.
Final Chilling
Chill the fully assembled pan in the fridge for at least 2 hours before cutting. This ensures clean slices and prevents crumbling. For make-ahead convenience, freeze the pan for 1 hour after chilling, then wrap tightly in plastic wrap and foil.
Thaw at room temperature for 30 minutes before serving—this preserves the texture and flavor perfectly. ❄️
Serving Tips
Bring the dessert to room temperature before serving to enhance the flavors and textures. If storing leftovers, keep them in an airtight container in the fridge for up to 5 days.
Reheat individual pieces in the microwave for 10-15 seconds to restore the gooey peanut butter layer. The crunchy cookie shells and fudgy brownie hold up beautifully when reheated this way.
Nutrition facts
Frequently asked questions
Can I make these without a food processor for the cookie crumble? If you don’t have a food processor, pulse the 1 cup mini marshmallows and 0.5 cup chocolate chips together in a strong blender or even chop them finely by hand with a knife. For a rustic texture, crush them in a zip-top bag with a rolling pin. Just
Why does my brownie layer turn out cakey instead of fudgy?
Overmixing the batter or baking too long are the usual culprits. For fudgy perfection, bake the brownie layer for 20-25 minutes at 350°F until the edges are set but the center still jiggles slightly. Also,
How do I store leftovers to keep them fresh?
Keep the assembled dessert in an airtight container in the fridge for up to 5 days or freeze for 3 months. For best texture, let them sit at room temperature for 10 minutes before serving. If reheating, microwave individual pieces for 10-15 seconds to restore the peanut butter layer’s gooeyness. The cookie crumble stays crispy when stored properly!
Can I substitute peanut butter with another nut butter?
Yes, but the flavor will differ. Almond or cashew butter work well, but they lack peanut butter’s signature richness. For a closer match, mix 0.5 cup almond butter with 0.5 cup sunflower seed butter—this combo mimics peanut butter’s texture and taste. Just reduce the brown sugar slightly to 0.3 cup since nut butters are sweeter.
What’s the secret to getting clean cuts when slicing?
Chill the pan for at least 2 hours before cutting—this firms up all layers. Dip a sharp knife in hot water between slices to create a clean edge. For extra precision, use a pizza wheel or serrated knife. If the crumble layer crumbles, let the dessert chill for another 30 minutes before trying again.
