Ingredients for chocolate chip cookie brownie reese cup
Twelve ingredients, three textures—brownie, cookie, and peanut butter magic in every bite.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for brownie base |
| Granulated Sugar 🍚 | 1 ½ cups | Light brown sugar for cookie dough |
| Packed Brown Sugar 🍚 | ½ cup | For brownie fudginess |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Vanilla Extract 🌿 | 1 tbsp | Pure extract, not imitation |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for light texture |
| Cocoa Powder 🍫 | ½ cup | Dutch-processed preferred |
| Baking Powder 🧂 | ½ tsp | For brownie lift |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Mini Chocolate Chips 🍫 | 1 ½ cups | Semi-sweet preferred |
| Peanut Butter 🥜 | ½ cup | Creamy, natural |
| Reese's Peanut Butter Cups 🍫 | 12 whole | Mini size if available |
| Chopped Peanuts 🥜 | ¼ cup | For cookie dough crunch |
| Semisweet Chocolate Chunks 🍫 | 1 cup | For cookie dough |
The peanut butter cups are the star here, so grab the mini size if possible—they melt just enough to create those pockets of peanut butter bliss without losing their crunch. For the peanut butter, natural, creamy is best—it adds richness without overpowering. I always grab Reese's from the bulk section at Trader Joe's because they're fresher than the regular store brands. The chocolate chips? Ghirardelli semi-sweet melts perfectly, but any good brand works. Pro tip: measure your flour by spooning it into the cup and leveling—don't scoop directly from the bag or you'll end up with too much.
No peanut butter cups? Use 12 chocolate-covered peanut clusters instead—they're basically the same thing. Running out of mini chips? Chop regular chips into smaller pieces for that same bite-sized texture. For the cookie dough, if you don't have chopped peanuts, crushed peanuts or even granola work. The chocolate chunks can be swapped for chocolate bars chopped into small pieces. Want to make this gluten-free? Substitute the all-purpose flour with a 1:1 gluten-free blend—just make sure it's sifted. The baking powder is non-negotiable though—it's what gives the brownie that perfect lift.
Store the baked dessert in an airtight container at room temperature for up to 3 days, or freeze for 2 months—it reheats beautifully. I like to portion mine into individual servings before freezing so I can grab one whenever the craving hits. The peanut butter flavor intensifies after a day or two, so if you can wait, the second day is actually the best. Keep the peanut butter cups and chocolate chunks refrigerated until ready to use—they'll melt faster in warm kitchens.

Step-by-step instructions for chocolate chip cookie brownie Reese cup fusion
This hybrid dessert combines rich brownie layers with cookie dough pockets and peanut butter surprises.
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—this should take about 3-4 minutes with a hand mixer. The mixture will nearly double in volume and turn pale.
Add the 2 whole large eggs, one at a time, mixing well after each addition. Stir in the 1 tablespoon vanilla extract, then sift in the 1.5 cups all-purpose flour, 0.5 cup cocoa powder, 0.5 teaspoon baking powder, and 0.5 teaspoon salt. Mix just until combined—don't overmix, or your brownies will be tough.
Create the Cookie Dough Layer
In a separate bowl, combine the 0.5 cup peanut butter and 1 cup semisweet chocolate chunks until smooth. In another bowl, mix the 1.5 cups mini chocolate chips and 0.25 cup chopped peanuts together. Spread half of the brownie batter evenly into the prepared pan.
Drop spoonfuls of the peanut butter-chocolate mixture onto the brownie layer, leaving space between each. Then, drop dollops of the mini chocolate chip-peanut mixture around the peanut butter pockets. Finally, spread the remaining brownie batter evenly over the top, creating a smooth layer.
Add the Reese's Surprise
Press the 12 whole Reese's peanut butter cups gently into the top brownie layer, leaving about ½ inch of each cup exposed. This creates those delightful hidden surprises when you cut into the finished dessert. Gently press down on the brownie layer to ensure good contact with the peanut butter cups.
Bake for 25-30 minutes until a toothpick inserted into the center comes out with a few moist crumbs. The edges should be set but the center should still look slightly fudgy. Let the dessert cool completely in the pan for at least 1 hour before slicing—this ensures clean cuts and prevents crumbling.
Chill and Serve
Once completely cooled, transfer the pan to the refrigerator and chill for at least 2 hours. This step is crucial—it allows the flavors to meld together and makes the texture perfect: fudgy brownies with cookie dough pockets and crispy peanut butter cups.
Slice into 12 equal squares and serve at room temperature. Each bite delivers rich chocolate brownie, peanut butter cookie dough, and a surprise Reese's peanut butter cup—all in one decadent package. Store leftovers in an airtight container in the refrigerator for up to 5 days or freeze for up to 3 months.
Pro Tips For Making Chocolate Chip Cookie Brownie Reese Cup
- Melt Butter Slowly: I learned this the hard way—dumping cold butter into hot sugar makes a greasy mess. Warm the butter in the microwave for 20 seconds first, then stir it into the sugar mixture. The butter will emulsify better, and your batter won’t look like a science experiment gone wrong.
- Use Room-Temp Eggs: Cold eggs sink to the bottom and create dense pockets in the batter. Let your eggs sit out for 30 minutes before cracking them—just enough time to warm up but not enough to turn rubbery. Your Reese cup layers will stay light and fudgy, not heavy.
- Don’t Overmix the Batter: Once you fold in the chocolate chips and cookie dough chunks, stop mixing after 10 strokes. Overworking the batter makes the final texture tough instead of chewy. The Reese cups need that gooey, imperfect center, not a brick.
- Bake in Two Batches: One 9x13-inch pan is tempting, but it’ll lead to uneven baking. Split the batter between two smaller pans (like two 8x8-inch dishes) for even browning. The edges won’t dry out while the center cooks, and you’ll avoid the sad, underbaked middle that ruins the Reese cup magic.
Essential equipment for great chocolate chip cookie brownie reese cup
Mixing Essentials
Start with a stand mixer or hand mixer for creaming butter and sugars—this ensures light, fluffy brownie texture. I recommend a KitchenAid Artisan Series for its power and durability, but any quality mixer works.
For measuring, use a digital kitchen scale for accuracy with ingredients like flour and cocoa powder—this prevents dry or dense results. 🧈
Baking Pan Prep
A 9x13-inch baking pan is perfect for this recipe, but line it with parchment paper for easy removal and clean slices. I use Silpat baking mats for non-stick convenience—they also prevent sticking better than parchment.
Preheat your oven to 350°F and let it fully adjust before baking to ensure even cooking.
Cookie Dough Tools
For the cookie dough pockets, use a small offset spatula to spread the peanut butter-chocolate mixture evenly. A cookie scoop (about 1 tablespoon size) helps create uniform dollops of the chocolate chip-peanut mixture.
I like the OXO Good Grips brand—they’re durable and easy to clean. Keep a small bowl nearby for mixing the peanut butter and chocolate chunks.
Reese Cup Placement
Pressing the Reese’s cups into the brownie layer requires a light touch—use your fingers or the back of a spoon to avoid breaking them. A small plate helps hold the cups steady while you position them.
For extra stability, gently press the brownie batter around the edges of each cup to secure them in place. 🍫
Cooling and Chilling
After baking, let the dessert cool completely on a wire rack before chilling. A large baking sheet works well for this. For chilling, I use a glass baking dish—it’s sturdy and keeps the dessert cold evenly.
Place the pan in the fridge for at least 2 hours to let the flavors meld and the textures set properly.
Slicing and Serving
Use a sharp chef’s knife or pizza cutter for clean slices. For extra precision, dip the knife in hot water and wipe it dry between cuts. Serve on a wooden board or marble slab for a rustic touch.
Store leftovers in an airtight container with parchment paper between layers to keep them fresh. ✨

Frequently asked questions
Can I make this dessert without Reese's cups?
Yes! Use 12 chocolate-covered peanut clusters instead—they're essentially the same thing. For a different twist, try mini peanut butter-filled pretzels or peanut butter-filled chocolate truffles. The key is maintaining that peanut butter surprise element for the texture contrast.
How do I prevent the Reese cups from melting too much?
Press them in gently and leave about ½ inch exposed above the brownie batter. Chill the dessert for at least 2 hours before slicing—this helps set the peanut butter cups. For extra stability, place the pan in the freezer for 15 minutes after pressing them in before baking.
Can I make this gluten-free?
Replace the 1.5 cups all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). Make sure it's sifted to maintain the same light texture. The baking powder is essential—don't substitute it. You might need to add 1 extra tablespoon of flour as gluten-free flours absorb differently.
Why did my dessert come out too dry?
Overbaking is the most common cause. The center should look slightly fudgy when done (25-30 minutes at 350°F). If your kitchen runs hot, reduce the temperature to 325°F. Also check your oven calibration—use an oven thermometer to verify accuracy. A 10-minute cool in the pan after baking helps retain moisture.
Can I make this ahead of time?
Yes! Bake it up to 2 days ahead and store in an airtight container at room temperature. For longer storage, freeze the entire pan (wrapped tightly) for up to 3 months. Thaw overnight in the fridge before serving. The flavors actually improve after 24 hours as the peanut butter infuses more.
