Ingredients for brownie cookie and reese's
Twelve ingredients transform into a decadent dessert with contrasting textures and flavors everyone will crave.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 ½ cups | Cold, cubed for brownie dough |
| Granulated Sugar 🍚 | 2 ¼ cups | Superfine preferred for smooth texture |
| Light Brown Sugar 🍚 | ½ cup | Packed, for cookie dough richness |
| Large Eggs 🥚 | 4 whole | Room temperature for even mixing |
| Unsweetened Cocoa Powder 🍫 | 1 cup | Dutch-processed for smoothness |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted, for light texture |
| Baking Powder 🍞 | ½ tsp | Aluminum-free for best results |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Vanilla Extract 🌿 | 2 tsp | Pure, high-quality extract |
| Peanut Butter 🥜 | 1 cup | Creamy, natural style preferred |
| Reese's Pieces 🍫 | 1 ½ cups | Original, not miniatures |
| Chocolate Chips 🍫 | 1 cup | Semi-sweet, 60% cacao |
| White Chocolate Chips 🍫 | ½ cup | For cookie dough contrast |
| Powdered Sugar 🍚 | ¼ cup | For cookie dough dusting |
| Flaky Sea Salt 🧂 | ½ tsp | For cookie dough finishing |
The cocoa powder is non-negotiable here—Dutch-processed creates that velvety smoothness in the brownie layer. I stock up on Valrhona or Ghirardelli when I can find it on sale, but Hershey's Special Dark works perfectly fine for everyday baking. The peanut butter? Natural, creamy style gives the cookie dough that signature peanut butter flavor without being overly sweet. Reese's Pieces are the star—original, not the miniatures—they melt just enough to create those gooey pockets without turning into a puddle. For the chocolate chips, Ghirardelli or Enjoy Life brands melt beautifully without seizing, and the white chocolate chips add a lovely contrast to the peanut butter flavor.
No Dutch-processed cocoa? Natural cocoa powder plus 1/4 tsp baking soda mimics the effect. Natural peanut butter works but add 1 tbsp sugar to compensate for the graininess. Short on Reese's Pieces? Chopped Reese's cups work in a pinch, though they'll be chunkier. The cookie dough gets its structure from the powdered sugar and butter—don't substitute with granulated sugar, or it'll turn out gummy. For the chocolate chips, chopped chocolate bars work if you're in a bind, but measure carefully since brands vary in density. The flaky sea salt is optional but absolutely essential for that restaurant-quality finish—it balances the sweetness perfectly.
This dessert is best made fresh but keeps beautifully for 3 days in an airtight container at room temperature. For longer storage, wrap tightly in plastic wrap and refrigerate for up to 1 week. The brownie layer stays fudgy when stored properly, but the cookie layer softens slightly—reheat at 350°F for 5-10 minutes to restore its chewiness. I always make a double batch because it disappears faster than you can say 'Reese's.' Freeze individual slices for up to 3 months—just thaw at room temperature before serving. The aroma alone will have your whole house gathering in the kitchen.

Step-by-step instructions for brownie cookie and Reese's recipe
Here's how to create the ultimate fudgy-crunchy masterpiece with perfect texture layers.
Create the Base Brownie Dough
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, combine the 1.5 cups unsalted butter (cold, cubed) with the 2.25 cups granulated sugar and 0.5 cup light brown sugar. This cold butter creates pockets of air that give the brownies their signature crackly tops.
Using an electric mixer on medium speed, beat the butter and sugars together for 3-4 minutes until light and fluffy. The mixture should nearly double in volume and become pale in color. Scrape down the sides of the bowl occasionally to ensure even mixing. This thorough creaming is what prevents dense, cakey brownies.
Incorporate Wet Ingredients
Add the 4 whole large eggs one at a time, mixing well after each addition until fully incorporated. The eggs should blend smoothly into the butter mixture, creating a thick, ribbon-like batter. Stir in the 2 teaspoons vanilla extract and 1 cup unsweetened cocoa powder, mixing until completely smooth.
In a separate bowl, whisk together the 1.5 cups all-purpose flour, 0.5 teaspoon baking powder, and 0.5 teaspoon salt. Sift this dry mixture directly into the wet ingredients and mix on low speed just until combined. You'll still see some flour streaks—this prevents overdevelopment of gluten that would make your brownies tough. The batter should be thick and fudgy-looking.
Prepare the Peanut Butter Layer
Spread half of the brownie batter evenly into the prepared baking pan. In a small bowl, mix together the 1 cup peanut butter with the 0.25 cup powdered sugar until smooth. Spread this peanut butter mixture evenly over the first layer of brownie batter, creating a thin, even coating.
Here's the thing—this layer needs to be thin but complete. Use a spatula to spread it smoothly, leaving no gaps. The peanut butter will create that signature cookie-like texture while keeping the fudgy brownie base intact. This is where the magic happens—where the cookie meets the brownie in perfect harmony.
Add Chocolate Layers and Bake
Spread the remaining brownie batter evenly over the peanut butter layer. Gently fold in the 1.5 cups Reese's Pieces, 1 cup chocolate chips, and 0.5 cup white chocolate chips using a spatula, being careful not to overmix. Sprinkle the 0.5 teaspoon flaky sea salt evenly over the top for that perfect salty-sweet contrast.
Bake for 25-30 minutes until a toothpick inserted in the center comes out with moist crumbs (not wet batter). The edges should be set but the center should still look slightly underbaked—this ensures maximum fudginess. The top will crack slightly as it cools, which is exactly what you want for that beautiful, rustic look.
Cool and Cut for Perfect Texture
Remove the pan from the oven and let it cool completely at room temperature for at least 2 hours. This long cooling period is crucial—it allows the layers to fully set and the flavors to meld together. Don't be tempted to cut into them while they're still warm, or you'll end up with messy, crumbly pieces.
Once fully cooled, use a sharp knife to cut into 12 equal squares. For clean cuts, dip the knife in hot water between each cut and wipe it dry. Each piece should reveal those beautiful layers of fudgy brownie, peanut butter cookie, and melty chocolate—this is the moment you've been waiting for. Serve at room temperature for the ultimate texture contrast.
Pro Tips For Making Brownie Cookie And Reese'S
- MELT BUTTER SLOWLY: I learned this the hard way—dumping cold butter straight into hot sugar makes a greasy mess that fights you the whole way. Instead, cut the butter into small cubes and melt it in the microwave for 30 seconds at a time, stirring between each interval. You want it just warm enough to blend smoothly, not hot enough to cook the eggs prematurely.
- WHISK EGGS UNTIL THICK: Don’t just crack and stir. Whisk those eggs until they’re pale, thick, and ribbon-like—about 2-3 minutes with a hand mixer. This step actually changes the texture of your cookies, giving them that perfect chewy center without being cakey. (Yes, even if you’re impatient like me.)
- DON’T OVERMIX THE DOUGH: Once you fold in the cocoa and chocolate chips, stop mixing the second everything is combined. Overworking the dough means tough, dense cookies instead of the tender, fudgy texture you’re after. Use a spatula to gently fold—just until the dry bits disappear.
- CHILL THE DOUGH: This isn’t the prettiest method, but it’s the tastiest. After mixing, pop the dough in the fridge for at least 30 minutes. It makes the cookies spread less, keeps the edges crisp, and—most importantly—prevents the Reese’s pieces from sinking to the bottom like sad, melted anchors. (Your future self will thank you.)

Frequently asked questions
Can I make this recipe with regular Reese's cups instead of Reese's Pieces?
Yes, but you'll need to chop them carefully! Use a sharp knife to cut 6 regular Reese's cups into small, even pieces (about 1.5 cups total chopped). The texture will be slightly chunkier, but the peanut butter-chocolate flavor will still shine. For best results, warm the chopped pieces slightly before adding to the batter so they soften during baking.
Why does the recipe call for both white and semi-sweet chocolate chips?
The combination creates the perfect flavor contrast! The semi-sweet chocolate chips provide deep, rich chocolate flavor that pairs beautifully with the peanut butter, while the white chocolate chips add a creamy, slightly sweet element. Together, they create pockets of melty goodness that balance the fudgy brownie and chewy cookie layers.
How do I prevent the peanut butter layer from turning out too thick?
Keep the peanut butter mixture thin and spread it evenly! The key is using just 1 cup peanut butter + 0.25 cup powdered sugar and spreading it as a thin, even layer over the brownie base. If it feels too thick, add 1-2 teaspoons milk or melted butter to help it spread smoothly. Overmixing can make the cookie layer dense, so mix just until combined.
Can I make this dessert ahead of time for a party?
This dessert actually tastes better the next day. Bake it 1 day ahead and store in an airtight container at room temperature. The flavors meld beautifully, and the textures stay perfect. For parties, cut into squares 4-6 hours before serving so the layers hold together. Reheat individual pieces at 350°F for 5 minutes if you prefer them warm.
What's the best way to serve this dessert?
Warm is ideal, but room temperature works too! For a restaurant-worthy presentation, serve with a scoop of vanilla ice cream or a drizzle of melted chocolate. The contrast of cold ice cream with the warm, fudgy brownie is unbeatable. You can also dust with powdered sugar or add a sprinkle of crushed peanuts for extra crunch.
