Ingredients for cookie dough reese's peanut butter cup brownie
Fudgy brownies meet Reese's and cookie dough—this list delivers the perfect trifecta.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Room temperature for mixing |
| Granulated Sugar 🍚 | 2 cups | Light brown sugar works too |
| Packed Brown Sugar 🍚 | 1 cup | For moisture and fudginess |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Vanilla Extract 🌿 | 2 tsp | Pure vanilla extract |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for smooth batter |
| Cocoa Powder 🍫 | ¾ cup | Natural, unsweetened cocoa |
| Baking Powder 🧂 | ½ tsp | For lift and texture |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Mini Reese's Peanut Butter Cups 🥜 | 1 ½ cups | Chopped if not mini size |
| Cookie Dough 🍪 | 1 ½ cups | Store-bought or homemade |
| Semisweet Chocolate Chips 🍫 | 1 cup | For extra richness |
| Peanut Butter 🥜 | ½ cup | Creamy, unsalted preferred |
The butter and sugars are your foundation. Use European-style butter if you can find it—it's richer and gives those brownies a silkier texture. For the peanut butter cups, mini size is ideal (no chopping needed), but if you've got full-size, just chop them roughly. Cookie dough? Store-bought is fine—I grab the refrigerated kind from Trader Joe's when I'm in a hurry, but homemade tastes even better. The cocoa powder matters here—Hershey's Special Dark or Dutch-processed for a smoother flavor. Don't skimp on the vanilla either—pure extract makes all the difference.
No mini Reese's? Chop regular ones—just be gentle so they stay intact. Cookie dough missing? Mix softened butter, sugar, and vanilla with flour (about 1 cup dough). Out of cocoa powder? Melted chocolate works at half the amount. The peanut butter can be natural (with oil), but creamy is easier to work with. For the chocolate chips, Enjoy Life brand is my go-to if you're avoiding dairy. And if you're feeling fancy, swap the semisweet chips for white chocolate chips—they melt beautifully into the batter.
Keep the butter and cookie dough refrigerated until ready to use. Brownies keep for 3 days in the fridge, but honestly, they disappear faster than that. For the cookie dough, if you're making it ahead, freeze it in a ball—thaw for 10 minutes before using. The peanut butter cups? Store in a cool, dark place—they last months. Portion the batter into pans before baking for clean layers. And if you're making these for a crowd, double the recipe—they're that good.
Why You'll Love This Recipe
- No Mixing Madness: I swear by this recipe because it’s one bowl—no separate batter or filling fuss. Just cream butter and sugars, fold in eggs and vanilla, then stir in the cookie dough chunks and peanut butter cups. The texture comes together like magic, no overmixing to stress about.
- Triple-Threat Flavor: That first bite hits you with warm, fudgy brownie (thanks to the brown sugar and butter), then the cool, creamy peanut butter from the cups, and finally the soft cookie dough pockets—it’s like dessert’s holy trinity. Honestly, my kids fight over the last piece, and I don’t even bake.
- Party or Pajamas: These brownies are equally at home on a holiday dessert table or as my 10 p.m. snack when I’m too tired to think. The rich chocolate and peanut butter keep them impressive enough for guests, but the cookie dough chunks make them feel indulgent enough for lazy nights.
- Budget Bargain: I make this with store-brand peanut butter cups and a bag of pre-made cookie dough—I’m talking under $10 for a pan full. The leftovers? They last days because they’re so good, and I can freeze half for when I’m too exhausted to bake later. (Yes, even on a Tuesday night.)
Step-by-step instructions for cookie dough Reese's peanut butter cup brownies
Here's how to make decadent brownies with layers of cookie dough and Reese's surprises.
Cream Butter and Sugars Together
In a large mixing bowl, combine the 1 cup unsalted butter and both sugars - the 2 cups granulated sugar and 1 cup packed brown sugar. Beat with an electric mixer on medium speed for about 3 minutes until light and fluffy. You'll see the mixture nearly double in volume and turn pale.
This creaming process incorporates air which creates that signature fudgy texture. I like to scrape down the sides of the bowl every minute to ensure everything gets evenly mixed. The butter should be completely smooth with no lumps remaining.
Add Eggs and Flavorings
Add the 2 whole large eggs one at a time, mixing well after each addition. Then stir in the 2 teaspoons vanilla extract. The mixture will look slightly thicker but should still be smooth. If using room temperature eggs, they'll blend in more easily.
This is where the flavor foundation gets built. The vanilla extract enhances all the other flavors while the eggs provide moisture and structure. Don't worry if the mixture looks slightly curdled - it'll come together when we add the dry ingredients.
Mix in Dry Ingredients and Cookie Dough
In a separate bowl, whisk together the 1.5 cups all-purpose flour, 0.75 cup cocoa powder, 0.5 teaspoon baking powder, and 0.5 teaspoon salt. Gradually add this dry mixture to the wet ingredients, mixing on low speed just until combined. Be careful not to overmix.
Next, fold in the 1.5 cups cookie dough and 0.5 cup peanut butter using a spatula. The batter will be thick and slightly sticky. This is where the magic happens - the cookie dough pieces will create pockets of gooey goodness throughout the brownies.
Layer with Chocolate Chips and Reese's Cups
In a 9x13-inch baking dish, spread half of the batter evenly. Then sprinkle half of the 1 cup semisweet chocolate chips and 1.5 cups mini Reese's peanut butter cups over the batter. Repeat with the remaining batter, chocolate chips, and Reese's cups.
Use a spatula to gently press down on the top layer just enough to create pockets for the chocolate and Reese's pieces. This layering technique gives you those delicious surprises in every bite. Don't worry about perfect distribution - the brownies will still be amazing even if some spots have more than others.
Bake to Perfect Fudgy Texture
Bake at 350°F for 25-30 minutes until the edges are set but the center still looks slightly underdone. A toothpick inserted in the center should come out with moist crumbs, not wet batter. The top should be crackly but not completely dry.
Let the brownies cool completely in the pan before cutting. This resting time allows the flavors to meld together and prevents them from falling apart when sliced. Once cooled, cut into squares and enjoy the perfect combination of fudgy brownie, cookie dough pockets, and Reese's surprises.
Pro Tips For Making Cookie Dough Reese'S Peanut Butter Cup Brownie
- MELT BUTTER SLOWLY: I learned this the hard way—dumping cold butter into a hot pan or mixer just makes it seize up. Instead, cut the butter into small cubes and let it melt gradually over low heat (or at room temp if mixing by hand). You want it creamy, not greasy, so the brownies don’t turn out dense or oily.
- WHISK EGGS ROOM TEMP: Cold eggs from the fridge will curdle when mixed with melted butter, and you’ll end up with weird lumps in your batter. Pop them in a bowl of warm water for 5 minutes first—just enough to make them pliable but not hot. The batter will be smoother, and the texture will be way better.
- STOP BEFORE IT LOOKS DONE: These brownies are fudgy, not cakey, so they’ll look undercooked when they’re actually perfect. Pull them out at the first sign of edges pulling away from the pan (usually 5–7 minutes before the recipe’s suggested time). The center should still jiggle slightly—it’ll set as it cools.
- SWAP BUTTER FOR BROWN SUGAR: Sounds weird, but it works: Replace half the butter (about ¼ cup) with packed brown sugar in the peanut butter filling. The extra moisture keeps the Reese’s layers gooey instead of dry, and the caramel notes play so well with the cookie dough flavor. Just don’t skip the vanilla—it balances the sweetness.
Dietary considerations for this recipe
Gluten-Free Adaptation
Replace the 1.5 cups all-purpose flour with a high-quality gluten-free blend like King Arthur Measure for Measure. Use 1:1 substitution and add 1 teaspoon xanthan gum to mimic gluten's structure.
For extra moisture, reduce the batter by ¼ cup since gluten-free flours absorb differently. I've tested this with Bob's Red Mill 1-to-1 and it works beautifully. 💪
Dairy-Free Options
Swap the butter for Earth Balance vegan butter and use dairy-free chocolate chips like Enjoy Life brand. For the peanut butter cups, opt for Reese's Vegan Peanut Butter Cups or make your own with dairy-free chocolate.
The cookie dough should be egg-free too—I recommend Ben & Jerry's non-dairy cookie dough or homemade with flax eggs (1 tbsp ground flax + 3 tbsp water per egg).
Nut-Free Swaps
Skip the peanut butter cups and cookie dough entirely—replace them with chopped dairy-free chocolate bars (like Lindt 70% dark) and sunflower seed butter cups (homemade with sunflower seed butter and dairy-free chocolate).
For cookie dough, use a seed butter like SunButter instead of peanut butter. The brownies will still be rich and fudgy without the nut allergens. ✨
Lower Sugar Version
Reduce the granulated sugar to 1.5 cups and the brown sugar to ½ cup, then add ¼ cup monk fruit sweetener or erythritol. Use sugar-free chocolate chips like Lily's brand and sugar-free peanut butter cups (check labels for no added sugars).
The texture stays fudgy but with fewer calories. I've found this works best with Swerve granulated for baking.
Refrigerated Cookie Dough
If you're avoiding raw eggs (like in store-bought cookie dough), make your own safe version with baked cookie dough or egg-free cookie dough. For the brownies, use baked cookie dough pieces (bake at 350°F for 10-12 minutes) to avoid any raw egg concerns.
The flavor is slightly different but still delicious and safe for everyone. 💛

Frequently asked questions
Can I use store-bought cookie dough instead of making my own?
Store-bought cookie dough works perfectly—just use 1.5 cups of refrigerated dough (like Trader Joe's or Pillsbury). For best results, let it soften slightly at room temperature before folding into the batter. If using pre-baked cookie dough, crush it into small chunks to mimic fresh dough texture.
How do I prevent the peanut butter cups from melting completely?
Bake at 350°F for 25-30 minutes max—overbaking will turn the peanut butter cups into a puddle. For extra insurance, place a few extra cups on top after baking and let them melt slightly during the final 5 minutes of bake time. Chill the brownies for 1 hour before slicing to help them set.
Can I make these brownies ahead of time?
Yes! Bake them up to 2 days ahead and store in an airtight container at room temperature. For longer storage (up to 1 week), wrap tightly and refrigerate. Bring to room temperature before serving—this helps the textures soften beautifully.
What if I don't have mini Reese's peanut butter cups?
No problem! Chop 12 full-size Reese's cups into small pieces (about 1.5 cups total) and sprinkle them evenly. For extra peanut butter flavor, add 2 tablespoons peanut butter swirls to the batter before baking. The texture will be slightly different but still delicious.
How do I make these extra fudgy?
Replace ¼ cup of the all-purpose flour with ¼ cup cocoa powder and reduce the baking time by 2-3 minutes. For even more fudginess, slightly underbake (toothpick should have moist crumbs) and let them cool completely before cutting. The centers will firm up as they cool.
