This cookie dough Reese's brownie recipe combines two irresistible textures and flavors into one decadent dessert—soft, gooey cookie dough swirled into rich, fudgy brownies with hidden peanut butter pockets. The contrast of warm chocolate and creamy peanut butter creates a flavor explosion that’s impossible to resist.

I developed this recipe after years of experimenting with brownie variations, and this fusion consistently earns rave reviews.

Ingredients for cookie dough reese's brownie

Rich chocolate, gooey cookie dough, and creamy peanut butter pockets—this dessert delivers maximum indulgence with minimal ingredients.

Ingredient Amount Notes
Unsalted Butter 🧈 1 ½ cups Cold, cubed for brownie texture
Granulated Sugar 🍚 2 cups Light brown preferred for depth
Packed Brown Sugar 🍚 1 cup Dark brown for caramel notes
Large Eggs 🥚 2 whole Room temperature for even mixing
Vanilla Extract 🌿 2 tsp Pure Madagascar bourbon preferred
All-Purpose Flour 🌾 1 ½ cups Sifted for light texture
Unsweetened Cocoa Powder 🍫 ¾ cup Dutch-processed for smoothness
Baking Powder 🍞 ½ tsp Aluminum-free for best rise
Diamond Crystal Kosher Salt 🧂 ½ tsp Fine grain preferred
Store-Bought Chocolate Chip Cookie Dough 🍪 1 ½ cups Unbaked, high-quality brand
Reese's Peanut Butter Cups 🥜 12 whole Mini size for even distribution
Semisweet Chocolate Chips 🍫 ½ cup 60% cacao for balance
White Chocolate Chips 🍫 ¼ cup For subtle contrast
Crushed Reese's Pieces 🥜 ¼ cup For garnish, optional
Melted Milk Chocolate 🍫 ¼ cup For drizzling, optional

The cocoa powder and sugars determine the brownie's depth. Dutch-processed cocoa from Valrhona or Ghirardelli elevates the chocolate flavor, but high-quality store brands like Hershey's Special Dark work perfectly. For the cookie dough, Ben & Jerry's or Betty Crocker brands provide the ideal texture—avoid overly sweet versions. Reese's peanut butter cups should be the classic milk chocolate variety, not the white or dark chocolate versions. The butter must be cold when creamed to achieve that signature fudgy texture; let it sit at room temperature for 30 minutes before starting, then cube it for even distribution. Pre-sift your dry ingredients to prevent lumps in the batter.

No Dutch-processed cocoa? Natural cocoa powder plus 1/4 tsp baking soda mimics the effect. Substitute cookie dough with homemade chocolate chip dough at the same volume, but reduce the flour in the brownie batter by 1/4 cup to balance moisture. For peanut butter cups, homemade peanut butter cups (melted peanut butter + chocolate) work beautifully if you're feeling ambitious. The chocolate chips can be swapped for chopped chocolate bars of equal weight. If you prefer a less sweet dessert, reduce the granulated sugar by 1/4 cup and increase the cocoa powder by 1 tbsp. For a nutty boost, fold in 1/4 cup chopped pecans with the cookie dough.

Store baked brownies in an airtight container at room temperature for up to 5 days, though they're best enjoyed within 2 days for maximum gooeyness. For longer storage, freeze individual portions wrapped in plastic for up to 3 months. To reheat, microwave for 10-15 seconds or warm in a 250°F oven for 5-10 minutes. The peanut butter pockets soften slightly after baking but remain detectable for days. For presentation, bake the brownies in a 9x13-inch pan for a classic sheet cake effect, or divide into two 8-inch pans for thicker slices. Garnish with crushed Reese's Pieces and a drizzle of melted chocolate just before serving for an elegant touch.

Step-by-step instructions for cookie dough Reese's brownies

This method delivers decadent fudgy brownies with swirls of cookie dough and hidden peanut butter surprises.

1

Prepare the Brownie Base

Preheat your oven to 350°F and line a 9x13-inch baking pan with parchment paper, leaving an overhang for easy removal. In a large mixing bowl, cream together the 1.5 cups unsalted butter and both sugars until light and fluffy—this should take about 3-4 minutes with an electric mixer. You'll know it's ready when the mixture nearly doubles in volume and becomes pale.

Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 2 teaspoons vanilla extract until fully combined. In a separate bowl, whisk together the 1.5 cups all-purpose flour, 0.75 cup unsweetened cocoa powder, 0.5 teaspoon baking powder, and 0.5 teaspoon diamond crystal kosher salt. Gradually fold the dry ingredients into the wet mixture until just combined—avoid overmixing to maintain a tender texture.

2

Create the Cookie Dough Swirls

Using a rubber spatula, gently fold 0.75 cups of the brownie batter into the 1.5 cups store-bought chocolate chip cookie dough until evenly distributed. Set aside. Spread the remaining brownie batter evenly into the prepared pan, creating a smooth, even layer. Using a spoon or small offset spatula, create wells in the batter at regular intervals—about 2 inches apart—and drop spoonfuls of the cookie dough mixture into each well.

Gently swirl the cookie dough into the batter using the tip of the spoon, creating marbled patterns. Press down lightly to ensure the cookie dough integrates with the brownie batter. Sprinkle 0.25 cup crushed Reese's pieces evenly over the top for added texture and flavor contrast.

3

Add Peanut Butter Surprises

Using a small knife or offset spatula, carefully cut small wells into the brownie batter—about 1 inch deep—leaving enough batter around each to hold the peanut butter cups in place. Gently press the 12 whole mini Reese's peanut butter cups into these wells, making sure they're fully seated and not floating on top. This ensures they melt evenly throughout the brownie rather than creating a separate layer.

Sprinkle the remaining 0.5 cup semisweet chocolate chips and 0.25 cup white chocolate chips evenly over the top for additional bursts of flavor. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs but no wet batter.

4

Finish and Drizzle

Remove the brownies from the oven and let them cool in the pan for 10 minutes before transferring to a wire rack to cool completely. While still warm, melt the 0.25 cup milk chocolate in a double boiler or microwave, stirring until smooth. Drizzle the melted milk chocolate over the top of the brownies in a zigzag pattern, allowing it to create an elegant finish.

Allow the brownies to set for at least 1 hour before slicing into 9 equal pieces. The result should be rich, fudgy brownies with pockets of cookie dough and melted peanut butter surprises throughout. Serve at room temperature for the best texture and flavor experience.

Pro Tips For Making Cookie Dough Reese'S Brownie

  • Melt Butter Slowly: I learned this the hard way—dumping cold butter into hot sugar makes a greasy mess. Instead, melt the butter first (just until it turns liquid, not brown), then let it cool to room temperature before mixing. That way, the butter blends smoothly with the sugars without separating.
  • Use Room-Temp Eggs: Cold eggs from the fridge will make your batter lumpy and dense. Let them sit in warm water for 5 minutes before cracking—just enough to bring them to about 70°F. The batter will be lighter, and the texture will be that perfect fudgy-yet-crackly hybrid you’re after.
  • Don’t Overmix the Batter: I used to beat this like a smoothie, but that’s how you end up with tough, cakey brownies. Mix the wet and dry ingredients just until the flour disappears—about 15 seconds after the last trace vanishes. Overmixing develops gluten, and nobody wants a chewy brownie when they’re craving Reese’s.
  • Bake in Two Batches: This isn’t a pretty trick, but it works: Split the dough into two 8x8 pans instead of one. The brownies will bake faster, stay fudgy in the center, and avoid the sad, underdone middle that happens when you overcrowd the oven. (Yes, even if you’re impatient like me.)

Best sauces and condiments for this cookie dough reese's brownie

Peanut Butter Drizzle

After baking, elevate your brownies with a warm peanut butter drizzle made from ½ cup creamy peanut butter and 2 tablespoons heavy cream. Microwave in 15-second bursts until smooth, then drizzle over the warm brownies.

The heat helps the peanut butter melt into the cookie dough pockets, creating a gooey, peanut-buttery surprise in every bite. 🥜

Chocolate Ganache

For a luxurious finish, make a quick dark chocolate ganache by heating ½ cup heavy cream until steaming, then pouring it over ½ cup chopped dark chocolate (70% cacao). Let sit for 2 minutes, then stir until silky smooth.

Drizzle over the cooled brownies for a glossy, decadent sheen that enhances the chocolate flavor without overpowering the peanut butter.

Salted Caramel Swirl

Add a sophisticated twist by swirling store-bought salted caramel sauce (like Trader Joe’s or Smucker’s) into the batter before baking. Use a spoon to create ribbons in the brownie mixture, then press mini Reese’s cups on top.

The salty-sweet caramel contrasts beautifully with the peanut butter and chocolate, adding depth to each bite. 💫

Whipped Cream Topping

Serve your brownies with a dollop of homemade whipped cream sweetened with 1 teaspoon powdered sugar and flavored with ½ teaspoon vanilla extract. The light, airy texture balances the richness of the brownies, while the vanilla complements the peanut butter.

For extra flair, dust with crushed graham crackers or peanut butter powder for a playful crunch.

Spiced Chocolate Sauce

Infuse your chocolate sauce with warmth by adding ½ teaspoon cinnamon and ¼ teaspoon cayenne pepper to the melted chocolate drizzle. This subtle spice blend enhances the peanut butter’s nuttiness while adding a hint of heat.

Pair it with a sprinkle of flaky sea salt on top for a sophisticated contrast that keeps every bite exciting.

Peanut Butter Frosting

For a frosting-like finish, whip ½ cup creamy peanut butter with 2 tablespoons softened butter, ½ cup powdered sugar, and 1 teaspoon milk until smooth. Spread a thin layer over the cooled brownies, then press crushed Reese’s Pieces on top.

This adds a creamy, peanut-buttery frosting that ties all the flavors together in one cohesive, indulgent bite. 🍫

Frequently asked questions

1

Can I make this recipe without store-bought cookie dough?

Use 1.5 cups homemade chocolate chip cookie dough instead, but reduce the flour in the brownie batter by 1/4 cup to balance moisture. For best texture, let the dough cool slightly before mixing into the batter. The flavor will be fresher, though store-bought saves time.

2

How do I prevent the peanut butter cups from sinking to the bottom?

Press them gently into 1-inch deep wells in the batter, leaving enough batter around each to hold them in place. Don’t overmix the batter before adding them, as this can cause sinking. Bake at 325°F (not higher) to ensure even melting without burning.

3

What’s the best way to store leftovers?

Keep in an airtight container at room temperature for up to 5 days, though they’re best enjoyed within 2 days for maximum gooeyness. For longer storage, freeze individual portions for up to 3 months. Reheat briefly in a 250°F oven for 5 minutes to restore texture.

4

Can I use regular Reese’s cups instead of mini ones?

Yes, but reduce the quantity to 6-8 regular cups to maintain balance. Cut them in half before pressing into the batter, and adjust baking time by 2-3 minutes if needed. Mini cups melt more evenly, but full-size ones create bigger surprises!

5

Why did my brownies turn out cakey instead of fudgy?

Overmixing the batter or using too much flour causes cakey texture. Stick to just combined when folding dry ingredients, and ensure your butter is cold but not frozen before creaming. For extra fudginess, reduce the flour by 1/4 cup next time.
