Desserts
This cookie dough Reese's brownie recipe delivers the perfect marriage of two beloved desserts—fudgy brownie texture meets cookie dough gooeyness with rich peanut butter swirls. The secret lies in layering a dense brownie base with pockets of cookie dough and Reese's pieces, creating every bite a flavor explosion.
I developed this recipe during a baking experiment when I wanted to combine my love for both desserts into one decadent treat.
What makes these brownies special is their textural contrast—the outside stays rich and fudgy while the inside reveals creamy cookie dough pockets and melty Reese's swirls.
The recipe uses simple pantry staples like flour, cocoa powder, and peanut butter, but the magic happens in the mixing technique and precise baking time. You'll need about 25 minutes in the oven for perfectly set edges and gooey centers.
The result is a dessert that looks impressive but requires no professional skills—just a few key steps and patience for the layers to set. Each slice delivers that perfect balance of sweet, nutty, and chocolatey flavors, making it ideal for holidays, parties, or satisfying a late-night craving.
These brownies are sure to disappear quickly, so make a batch and enjoy while they're fresh.
For extra indulgence, top with melted peanut butter drizzle or crushed Reese's pieces. The combination of textures and flavors makes this recipe a standout for anyone who loves chocolate desserts with a twist. Let's get baking!
Ingredients for cookie dough reese's brownie
Pantry staples plus two decadent twists—cookie dough and peanut butter swirls.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat preferred |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Packed Brown Sugar 🍚 | ½ cup | Light or dark variety |
| All-Purpose Flour 🌾 | 1 cup | Sifted for best texture |
| Cocoa Powder 🍫 | ¾ cup | Dutch-processed preferred |
| Baking Powder 🍞 | ½ tsp | Aluminum-free recommended |
| Salt 🧂 | ¼ tsp | Fine sea salt |
| Vanilla Extract 🌸 | 1 tsp | Pure alcohol-free if preferred |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Creamy Peanut Butter 🥜 | ½ cup | Natural, no added sugar |
| Mini Reese's Pieces 🍫 | 1 cup | Original flavor preferred |
| Cookie Dough Mix 🍪 | 1 box | 15.25 oz box (Pillsbury preferred) |
| Semisweet Chocolate Chips 🍫 | 1 cup | Enjoy Life brand for allergies |
The butter and sugars are your foundation here. Use European-style butter if you can find it—higher fat content for richer flavor. I grab mine at Whole Foods or Trader Joe's when I'm stocking up. For cocoa powder, Dutch-processed gives that smoother, deeper chocolate taste (Hershey's Special Dark is my go-to). The peanut butter? Natural, no-sugar-added keeps things balanced—skip the jelly version. Mini Reese's pieces should be the original kind (not peanut butter cups), and I always buy the 11 oz bag from the bulk bin at Costco—way cheaper than single servings. Pro tip: Toast the chocolate chips for 5 minutes at 300°F to deepen their flavor before mixing.
No Dutch-processed cocoa? Natural cocoa powder at half the amount works, but the flavor will be slightly bitter. Out of vanilla? Almond extract at half the amount is a decent swap. The cookie dough mix? Betty Crocker or homemade both work—just make sure it's creamy, not cakey. For extra peanut butter flavor, add 1 tbsp peanut butter powder to the dry ingredients. Want to skip the Reese's? Chopped peanuts or extra chocolate chips add crunch. And if you're feeling wild, swap the semisweet chips for white chocolate chips—trust me, it's delicious.
These brownies keep for 5 days in an airtight container at room temperature, but honestly, they won't last that long. For longer storage, wrap tightly in plastic and freeze for up to 3 months. I like to portion them into individual squares before baking so they're ready to grab. The texture changes slightly when reheated—microwave for 15 seconds to bring back that gooey center. Leftovers? Crush into ice cream or use as cake layer filling. Worth making a double batch.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe because it’s one bowl, one spatula—no food processor, no whisking until my arms give out. Just melt the butter, toss in the sugars, and fold in the flour and cocoa until it’s just combined. That’s it. The dough comes together faster than I can scroll through my phone.
- Fudgy-Chewy Magic: Between us, this is the only brownie recipe where I actually fight over the last piece. The brown sugar keeps it moist while the cocoa gives that deep, chocolatey punch—like eating cookie dough that somehow got better. Honestly, the moment I taste that first bite, I forget to breathe.
- Double-Duty Dessert: I make these for everything—birthday cakes, potlucks, or just because I’m craving something rich. They’re sturdy enough to slice into neat squares (no crumbling!) and freeze beautifully. Pro tip: Warm one up in the microwave for 10 seconds, and it’s like it was just baked.
- Pantry Staple Power: Here’s what sold me—this uses ingredients I always have: butter, sugar, flour, cocoa. No weird specialty items, no last-minute store runs. A single batch costs me less than $5 and stretches for days. Leftovers? They’re the best kind—reheated, shared, or stashed for when I need a quick pick-me-up.
Step-by-step instructions for cookie dough Reese's brownie recipe
Here's how to make these decadent brownies with layers of cookie dough and peanut butter swirls—every bite packs all the flavors you love.
Cream the Butter and Sugars Together
In a large mixing bowl, combine the 1 cup unsalted butter (make sure it's room temperature) with the 2 cups granulated sugar and 0.5 cup packed brown sugar. Using a hand mixer or stand mixer on medium speed, beat everything together for about 3-4 minutes. You'll know it's ready when the mixture is light and fluffy—it should nearly double in volume and look pale in color.
This creaming process is crucial because it incorporates air into the batter, which helps create that signature fudgy texture. If the butter isn't softened, the mixture will clump and your brownies might turn out dense. I like to press the butter between two sheets of wax paper and let it sit for 10-15 minutes if it's still too cold.
Mix in Wet Ingredients and Dry Components
Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 tsp vanilla extract. The mixture will look slightly curdled at first, but don't worry—it'll come together when you add the dry ingredients. Next, mix in the 0.5 cup creamy peanut butter until completely smooth. This is where that rich, nutty flavor starts to develop.
In a separate bowl, whisk together the 1 cup all-purpose flour, 0.75 cup cocoa powder, 0.5 tsp baking powder, and 0.25 tsp salt. Gradually add this dry mixture to the wet ingredients while mixing on low speed. Be careful not to overmix—just combine until no flour streaks remain. Overmixing can make your brownies tough instead of fudgy.
Fold in Cookie Dough and Chocolate
Using a spatula, gently fold in the 1 cup mini Reese's pieces and 1 cup semisweet chocolate chips. You want to distribute them evenly throughout the batter, but don't overmix—just swirl them in until they're mostly incorporated. The cookie dough mix will be thick and doughy, so it's okay if you see some chunks. In fact, that's part of the fun!
Now, fold in the 1 box cookie dough mix using a gentle folding motion. This is where the magic happens—you'll get pockets of cookie dough throughout the brownie batter. If the batter looks too thick, you can add 1-2 tablespoons of milk (not listed in ingredients, but if you have it) to help it come together better. The goal is a thick, spreadable consistency that holds its shape when dropped onto a baking sheet.
Prepare and Bake the Brownies
Preheat your oven to 350°F and line an 8x8-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Pour the batter into the prepared pan and smooth the top with a spatula. For extra decadence, I like to sprinkle a few extra mini Reese's pieces on top before baking.
Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter). The edges should be set, but the center should still look slightly underdone—this ensures that fudgy texture. If you're unsure, err on the side of underbaking. Brownies continue cooking as they cool, and overbaking makes them dry.
Cool and Cut for Maximum Enjoyment
Let the brownies cool in the pan for 15-20 minutes before transferring them to a wire rack to cool completely. This resting time is important—it allows the brownies to set properly so they hold their shape when you cut them. If you cut them too soon, they'll be crumbly and fall apart.
Once fully cooled, use a sharp knife to cut the brownies into 12 equal squares (about 2x2 inches each). For cleaner cuts, dip the knife in hot water and wipe it dry between slices. Serve at room temperature, and enjoy the perfect balance of fudgy brownie, peanut butter swirls, and pockets of cookie dough. These brownies are best enjoyed within 3-4 days—if they last that long!
Pro Tips For Making Cookie Dough Reese'S Brownie
- Cream Butter Slowly: If you dump cold butter into the mix and start beating, you’ll end up with a lumpy mess. Warm the butter slightly (just until it softens, not melts) first—it blends smoother and cuts down on mixing time. I used to rush this, and the dough always felt grainy. Trust me, a few extra seconds here saves frustration later.
- Sift That Cocoa: Cookie dough brownies rely on cocoa for that rich, fudgy texture, but unsifted cocoa powder is a sneaky source of lumps. Sift it with the flour—yes, even if it’s labeled "natural" or "Dutch-process." I learned this the hard way when my first batch had weird dry spots. Sifting also lightens the mix, so the batter flows better.
- Avoid Overmixing: Once you fold in the cookie dough chunks, stop mixing the second everything’s just combined. Overmixing develops gluten, which turns your fudgy brownie into a dense, cakey brick. Give it two gentle stirs—just enough to distribute the dough evenly. I’ve ruined batches by "helping" the batter too much, and you don’t want that.
- Test Doneness with a Toothpick: The classic toothpick test works, but here’s the catch: pull it out and check for moist crumbs, not just dry ones. If it comes out clean but the center’s still slightly wet, that’s perfect—it’ll set as it cools. Overbaking dries out the Reese’s and makes the texture sad. I used to pull them too soon, and the middle stayed doughy. Patience pays off.
Regional styles of cookie dough reese's brownie
Southern Style
In the South, these brownies get a warm, buttery twist with a touch of cinnamon and pecans. I like to fold in ½ cup chopped pecans along with the cookie dough mix, and add 1 tsp cinnamon to the dry ingredients.
The pecans add a delightful crunch that pairs beautifully with the peanut butter. Serve with a dollop of whipped cream and a drizzle of caramel sauce for that classic Southern dessert feel. 🍯
Midwest Cookie Dough Twist
The Midwest loves its cookie dough, so this version takes it to the next level by adding a layer of homemade cookie dough on top before baking. After pouring the brownie batter, spread ½ cup of prepared cookie dough (made with flour, sugar, butter, and vanilla) over the top.
Bake as directed, and you'll get a crispy cookie dough crust with gooey centers. Top with extra Reese's pieces for that Midwest sweet tooth satisfaction. 🥛
West Coast Nutty Crunch
Out West, where nutty flavors reign, I like to swap the mini Reese's pieces for chopped almonds or walnuts and add a layer of almond butter to the brownie batter. Replace half the peanut butter with 2 tbsp almond butter for a sophisticated nutty flavor.
Finish with a sprinkle of crushed hazelnuts for that California-inspired crunch. Serve with a side of vanilla bean ice cream for the ultimate West Coast dessert. 🌴
New England Brown Butter Swirl
For a richer, deeper flavor, New England bakers swear by brown butter. Replace the regular butter with 1 cup browned butter (cooled slightly) in the brownie batter. The nutty, caramelized flavor of brown butter pairs perfectly with the peanut butter swirls.
Add a swirl of peanut butter frosting (made with peanut butter, powdered sugar, and milk) before baking for an extra decadent touch. This version is perfect for chilly New England winters. ❄️
Texas-Style Spiced Brownie
In Texas, a little heat never hurt anyone. Add ½ tsp cayenne pepper and ½ tsp smoked paprika to the dry ingredients for a subtle kick. The cayenne gives a gentle warmth that balances the sweetness of the peanut butter and cookie dough.
Top with a sprinkle of crushed peanuts and serve with a scoop of peanut butter ice cream for a Texas-sized treat. 🌶️
Pacific Northwest Chocolate Lover’s Version
Chocolate lovers in the Pacific Northwest will adore this version, which cranks up the cocoa content. Replace the ½ cup peanut butter with ½ cup chocolate hazelnut spread (like Nutella) and add an extra ¼ cup cocoa powder to the dry ingredients.
Fold in ½ cup white chocolate chips for a creamy contrast. This version is rich, decadent, and perfect for those who can’t get enough chocolate. 🍫

Frequently asked questions
Can I make these without a boxed cookie dough mix?
Replace the boxed mix with 1 ½ cups homemade cookie dough (made with 1 cup flour, ½ cup softened butter, ½ cup sugar, and 1 tsp vanilla). Chill it for 30 minutes before folding into the brownie batter. The texture will be slightly denser but just as delicious.
Why do my brownies crack on top?
Cracking usually happens when the batter cools too quickly or the oven temperature fluctuates. To prevent this, ensure your oven is fully preheated to 350°F and avoid opening the oven door during baking. For extra insurance, place a baking sheet on the lower rack to create steam. The cracks won’t affect flavor—they’re just part of the fun!
How can I make these gluten-free?
Swap the all-purpose flour for a 1:1 gluten-free baking flour blend (like Bob’s Red Mill) and ensure your cookie dough mix is also gluten-free. Use ½ tsp xanthan gum in the dry ingredients to improve texture. Keep an eye on baking time—gluten-free brownies may need 2-3 extra minutes to set properly.
Can I add extra Reese’s pieces for more peanut butter flavor?
Yes, but go easy—too many can make the texture crumbly. Add up to ½ cup extra mini Reese’s pieces to the batter, but reduce the chocolate chips by ½ cup to balance moisture. For a swirl effect, spoon dollops of peanut butter into the batter before baking.
How do I store leftovers to keep them fresh?
Wrap tightly in plastic wrap or store in an airtight container at room temperature for up to 5 days. For longer storage, freeze individual squares for up to 3 months. Thaw at room temperature for 1 hour or microwave for 10 seconds to revive the gooey centers.
