This cookie dough Reese's peanut butter cup brownie recipe delivers the ultimate dessert experience—rich, fudgy chocolate brownie layers swirled with creamy peanut butter and pockets of cookie dough. The secret lies in balancing textures: dense brownie base, gooey cookie dough swirls, and melty Reese's cups that hold their shape.

Serve warm with vanilla ice cream or at room temperature for a show-stopping centerpiece. The contrast of warm brownie, cool cookie dough, and creamy peanut butter creates an experience that rivals anything from a bakery. Let's create this decadent treat that's sure to become a new favorite.
Ingredients for cookie dough reese's peanut butter cup brownie
Twelve decadent ingredients transform into a showstopping dessert with perfect texture balance.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 ½ cups | Softened for brownie base |
| Granulated Sugar 🍚 | 2 cups | Light brown preferred |
| Light Brown Sugar 🍚 | 1 cup | Packed firmly |
| Large Eggs 🥚 | 4 whole | Room temperature |
| Vanilla Extract 🍯 | 2 tsp | Pure Madagascar preferred |
| All-Purpose Flour 🌾 | 1 cup | Sifted for even texture |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | Dutch-processed preferred |
| Baking Powder 🍞 | ½ tsp | Aluminum-free |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Peanut Butter 🥜 | 1 cup | Creamy, natural style |
| Cookie Dough Mix 🍪 | 1 cup | Homemade or quality store-bought |
| Reese's Peanut Butter Cups 🍫 | 12 whole | Mini size preferred |
| Semisweet Chocolate Chips 🍫 | 1 cup | Enjoy Life brand for allergies |
| Vanilla Ice Cream 🍦 | 2 cups | Optional serving suggestion |
The cocoa powder is non-negotiable—Dutch-processed creates that signature velvety texture. Valrhona or Ghirardelli brands deliver restaurant-quality results, but Hershey's Special Dark works in a pinch. For the peanut butter, natural style with no added sugar ensures the perfect balance of richness. Reese's cups should be the mini size—they melt just enough to create pockets of peanut butter without losing their iconic crunch. I always buy an extra bag because they disappear fast when baking. The cookie dough mix can be homemade (use a trusted recipe) or store-bought—just check for egg content if avoiding raw eggs.
No Dutch-processed cocoa? Natural cocoa plus 1/4 tsp baking soda mimics the effect. Short on peanut butter? Substitute almond butter or tahini for a nutty alternative, though the texture will differ slightly. Homemade cookie dough? Use a mix with softened butter and vanilla for best results. For the chocolate chips, Enjoy Life brand is my go-to for allergy-friendly baking, but any high-quality chips work. The ice cream is optional but highly recommended—Breyers vanilla or Ben & Jerry's Phish Food both pair perfectly. If you're feeling adventurous, swap the ice cream for whipped cream or caramel sauce for a different twist.
Store the baked brownies in an airtight container at room temperature for up to 5 days. For longer storage, wrap individually in plastic and freeze for up to 3 months. The texture improves after 24 hours as the flavors meld. When serving, let them sit at room temperature for 15-20 minutes before slicing for clean cuts. The cookie dough and peanut butter elements stay freshest when the brownies are kept cool, so avoid storing them in warm environments. Portion into single servings for easy grab-and-go indulgence—perfect for lunchboxes or office treats.

Step-by-step instructions for cookie dough Reese's peanut butter cup brownies
Here's the method for creating decadent, fudgy brownies with peanut butter swirls and Reese's cups.
Prepare the Brownie Base
Preheat your oven to 350°F and line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. In a large mixing bowl, cream together the 1.5 cups unsalted butter, 2 cups granulated sugar, and 1 cup light brown sugar on medium speed until light and fluffy, about 3-4 minutes. This step incorporates air, which creates the signature fudgy texture.
Add the 4 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 cup all-purpose flour, 0.75 cup unsweetened cocoa powder, 0.5 teaspoon baking powder, and 0.5 teaspoon salt. Gradually fold the dry ingredients into the wet mixture until just combined—avoid overmixing to maintain the fudgy texture.
Create the Peanut Butter Swirls
In a small bowl, combine the 1 cup peanut butter and 1 cup cookie dough mix until smooth and well blended. This mixture will create the signature peanut butter swirls throughout the brownies. Spread half of the brownie batter evenly into the prepared baking pan, using a spatula to create an even layer.
Drop spoonfuls of the peanut butter mixture evenly over the brownie base, spacing them about 2 inches apart. Using a butter knife, gently swirl the peanut butter mixture into the brownie batter, creating marbled patterns. This step ensures every bite has both rich chocolate and creamy peanut butter flavors.
Add Reese's Cups and Chocolate Chips
Spoon the remaining brownie batter over the peanut butter swirls, spreading it evenly across the pan. Gently press down the 12 whole Reese's peanut butter cups into the batter, spacing them evenly. They should be partially submerged but still visible on the surface. Sprinkle the 1 cup semisweet chocolate chips evenly over the top of the batter.
This layering creates pockets of melted chocolate and peanut butter cups throughout each brownie, delivering surprise bites with every slice. The chocolate chips will create additional pockets of melted chocolate, enhancing the overall texture and flavor.
Bake to Perfect Fudgy Texture
Bake the brownies in the preheated oven for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs but no wet batter. The edges should be set, but the center should remain slightly soft and fudgy. Avoid overbaking, as this can make the brownies dry and cakey.
Once done, let the brownies cool in the pan for 10 minutes before transferring them to a wire rack to cool completely. This cooling period allows the brownies to set properly, making them easier to slice and serve. For the ultimate experience, serve each piece with a scoop of the 2 cups vanilla ice cream on the side.
Pro Tips For Making Cookie Dough Reese'S Peanut Butter Cup Brownie
- MELT BUTTER SLOWLY: If you dump cold butter into the dry ingredients, you’ll end up with lumps that fight you the whole way. Instead, melt the butter first—just until it’s liquid but not browned—then let it cool for 5 minutes before mixing. This keeps the batter smooth without cutting the fat too much, which is key for that fudgy texture.
- WHISK EGGS ROOM TEMP: Cold eggs from the fridge will curdle when they hit the warm butter mixture, leaving you with a weird, grainy batter. Pop those eggs out 10 minutes early, crack them into a bowl, and give them a quick whisk. Your brownies will bake evenly, and the cookie dough pockets won’t turn rubbery.
- STOP WHEN EDGES SET: I used to pull these out too soon, thinking they’d keep baking—wrong. The edges should look set (not dry or cracked), but the center should still jiggle slightly. Let them rest 10 minutes before slicing, or the Reese’s cups will ooze out like a science experiment gone wrong.
- SWAP BROWN SUGAR HALFWAY: Mix half the brown sugar into the dry ingredients first, then fold in the rest with the melted butter. This keeps the moisture balanced so the cookie dough swirls stay soft, not dense. (Yes, it’s extra stirring, but it’s worth it.)
Essential equipment for this dish
Mixing Bowls
Invest in a set of stainless steel mixing bowls—I recommend OXO Good Grips for their non-slip bases and durable construction. A large 8-quart bowl handles the brownie batter perfectly, while a small 2-quart bowl works for the peanut butter-cookie dough mixture.
These bowls prevent spills when combining wet ingredients and keep your workspace organized. 🍫
Baking Pan Essentials
Use a 9x13-inch heavy-duty baking pan—I swear by Wilton Perfect Results pans for even heat distribution. Line it with parchment paper (not wax paper) to prevent sticking and ensure clean removal.
For extra insurance, lightly grease the parchment with coconut oil before adding batter. Avoid dark pans—they can over-bake edges.
Measuring Tools
Precision matters with this recipe! A digital kitchen scale (like OXO Good Grips) is ideal for measuring butter and sugars, but if you prefer cups, use liberty measuring cups with pour spouts.
For dry ingredients, sift through a fine-mesh strainer to avoid lumps. A microplane comes in handy for grating chocolate if you want to add extra texture. 🔥
Swirling Tools
The secret to perfect peanut butter swirls lies in your tools. Use a long, flexible silicone spatula (like OXO Good Grips) to spread batter evenly, then a butter knife for creating marbled patterns.
For Reese's cups, I recommend mini size (1.69 oz) to melt just enough without losing their shape. A small offset spatula helps press them gently into the batter.
Cooling & Storage
Let brownies cool in the pan for 10 minutes before transferring to a wire cooling rack. For storage, I use amber glass containers with airtight lids to preserve freshness. If freezing, wrap individual slices in plastic wrap and store in a ziplock bag for up to 3 months.
A sharp chef's knife (like Mercer Culinary) ensures clean slices after chilling for 30 minutes in the fridge. ✨

Frequently asked questions
Can I make this recipe without Reese's peanut butter cups?
Swap the Reese's cups for mini peanut butter cups or even chopped peanuts mixed into the batter for a nutty crunch. For a chocolate twist, use mini chocolate chips or chopped dark chocolate instead. The peanut butter swirls will still deliver that signature flavor, just without the iconic peanut butter cup pockets.
Why does my cookie dough layer turn out too dry?
Overmixing the cookie dough or using dry ingredients (like store-bought mix with added stabilizers) can cause dryness. Use softened butter and mix just until combined—no more than 1 minute. For homemade cookie dough, add 1 tablespoon sour cream or Greek yogurt to keep it moist. Chill the dough for 30 minutes before mixing to prevent excess air incorporation.
How do I prevent the peanut butter swirls from sinking to the bottom?
Work quickly when adding the peanut butter mixture—drop spoonfuls onto the batter and swirl gently with a knife before covering with the remaining batter. Avoid overmixing after adding the swirls, as this can cause them to disperse. For extra stability, press the Reese's cups into the batter firmly but gently so they stay partially submerged without sinking completely.
Can I make these brownies ahead of time?
Yes! Bake them 1 day in advance and store in an airtight container at room temperature. The flavors meld beautifully overnight, making the brownies even richer. For longer storage, freeze individual slices wrapped in plastic for up to 3 months. Thaw at room temperature for 1-2 hours before serving to restore the perfect texture.
What's the best way to add extra peanut butter flavor?
Increase the peanut butter in the swirls to 1.5 cups or add 2 tablespoons peanut butter powder to the brownie batter. For a decadent twist, top with a peanut butter glaze (melt ½ cup peanut butter + ½ cup powdered sugar + 1 tsp milk) before baking. This enhances the peanut butter notes without altering the brownie's fudgy texture.
