Desserts
This brownie Reese cup cookie recipe delivers the ultimate dessert trifecta—fudgy brownie layers, gooey peanut butter cups, and crispy cookie edges all in one decadent bite. 🌟 The secret lies in baking a rich chocolate brownie base, embedding store-bought or homemade Reese’s cups, then finishing with a buttery cookie crumble that adds texture contrast.
I perfected this recipe after years of testing, ensuring every forkful delivers that perfect balance of sweet, salty, and crunchy.
The process starts with a classic brownie batter—dense, moist, and packed with cocoa powder for that signature fudgy texture. While it cools, you’ll press Reese’s cups into the center, creating pockets of peanut butter bliss that melt at the right moment.
The final touch? A cookie crumble topping made from crushed chocolate cookies and melted butter, baked until golden for that irresistible crunch. This isn’t just dessert—it’s an experience that’ll have everyone asking for seconds.
What makes this recipe truly special is how it combines three beloved treats into one cohesive dessert. The brownie provides structure, the Reese’s cups add that signature peanut butter crunch, and the cookie topping elevates it to restaurant-quality indulgence.
Plus, it’s easier than it looks—no fancy techniques, just layering and baking. The result? A showstopping dessert that’s perfect for holidays, dinner parties, or satisfying a serious sweet tooth.
For an extra touch, chill the baked cookies for at least 2 hours before slicing—this ensures clean cuts and lets the flavors meld even more. You can also swap store-bought Reese’s cups for homemade peanut butter cups if you’re feeling ambitious.
Either way, this recipe delivers a dessert that’s equal parts impressive and foolproof. Let’s get baking!
Ingredients for brownie reese cup cookie
Twelve ingredients, three decadent layers—this dessert is pure magic in every bite.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 ½ cups | Cold for crumble topping |
| All-Purpose Flour 🌾 | 2 cups | Sifted for brownie batter |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred for smooth texture |
| Unsweetened Cocoa Powder 🍫 | 1 cup | Dutch-processed for rich flavor |
| Large Eggs 🥚 | 4 whole | Room temperature for even baking |
| Vanilla Extract 🥛 | 2 tsp | Pure extract for authentic flavor |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Chocolate Cookies 🍪 | 1 ½ cups | Crushed (like Oreos or homemade) |
| Reese's Peanut Butter Cups 🥜 | 12 whole | Store-bought or homemade |
| Semisweet Chocolate Chips 🍫 | 1 cup | For extra richness in brownie |
| Peanut Butter 🥜 | ½ cup | Creamy for homemade cups |
| Powdered Sugar 🍚 | ¼ cup | For dusting finished cookies |
The cocoa powder and chocolate chips are non-negotiable for that signature fudgy texture. Dutch-processed cocoa from Ghirardelli or Valrhona makes all the difference—it’s smoother and richer. For the peanut butter cups, Reese’s is the gold standard, but if you’re feeling fancy, make your own with creamy peanut butter and chocolate. The cookie crumble topping? Oreos or homemade chocolate cookies work best—just crush them finely for that perfect crunch. I always grab extra butter (the cold, unsalted kind) since it’s used in both the brownie and cookie topping.
No Reese’s cups? Homemade peanut butter cups are surprisingly easy—just melt chocolate, mix with peanut butter, and chill. Short on chocolate chips? Swap for chopped chocolate bars (like Ghirardelli squares) or even dark chocolate chunks. The powdered sugar is just for dusting, but if you’re feeling wild, add a sprinkle of flaky sea salt on top for a sweet-salty kick. And trust me on the eggs—room temperature is key for even baking, so take them out of the fridge 30 minutes before mixing. The flour should be sifted to avoid lumps in the brownie batter.
This dessert needs time to set—2 hours in the fridge before slicing is non-negotiable. Store leftovers in an airtight container for 5 days (if they last that long). For parties, bake ahead and freeze the assembled cookies for up to 3 months. Just thaw at room temperature before serving. Pro tip: Line your pan with parchment paper for easy removal, and press the Reese’s cups firmly into the brownie layer so they stay put during baking.

Step-by-step instructions for brownie Reese cup cookies
Here's how to create decadent cookies with fudgy brownie centers and Reese's surprises!
👨🍳 Step 1: Make the Brownie Dough Foundation
Preheat your oven to 350°F and line two 9-inch round baking pans with parchment paper. In a large mixing bowl, cream together the 1.5 cups unsalted butter and 2 cups granulated sugar until light and fluffy—about 3-4 minutes with an electric mixer. You'll see the mixture nearly double in volume and become pale. This step is crucial for that tender, cake-like texture we want in these cookies.
In a separate bowl, whisk together the 2 cups all-purpose flour, 1 cup unsweetened cocoa powder, 0.5 tsp salt, and 1 cup semisweet chocolate chips. Gradually add this dry mixture to your butter-sugar blend, mixing on low speed just until combined. Be careful not to overmix—you should still see small flour streaks. Add the 4 whole large eggs one at a time, mixing well after each addition, followed by the 2 tsp vanilla extract. The dough will be thick and fudgy—this is exactly what we want!
🥘 Step 2: Prepare the Reese's Peanut Butter Cup Filling
While your brownie dough rests, it's time to make the peanut butter cups. In a small bowl, combine the 0.5 cup peanut butter and 0.25 cup powdered sugar, mixing until smooth. This will be our filling for the Reese's cups. For each of the 12 whole Reese's peanut butter cups, carefully scoop out the chocolate centers, leaving the peanut butter cups intact. Set the chocolate shells aside for later.
Fill each peanut butter cup with about 1 teaspoon of your peanut butter mixture, pressing it down gently. Place the filled cups back in the refrigerator to firm up while you prepare the crumble topping. This step ensures each cookie gets that perfect peanut butter surprise in every bite!
🍳 Step 3: Create the Crumble Topping
In a food processor, pulse the 1.5 cups chocolate cookies (like Oreos or homemade) until they form fine crumbs. Add the 1.5 cups unsalted butter (cold from the fridge) and pulse until the mixture resembles coarse sand. This texture is perfect for creating that crispy, buttery topping we all love. If you don't have a food processor, you can crush the cookies by hand and cut in the butter with a pastry cutter.
Divide the crumble mixture evenly between the two prepared baking pans. Press it down firmly with a fork or your fingers to create an even layer. This topping is what gives these cookies their signature crunchy texture and irresistible flavor combination!
🥘 Step 4: Assemble and Bake the Cookies
Scoop about 2 tablespoons of brownie dough onto each peanut butter cup, gently pressing it down to create a flat base. Place each filled cup in the center of the crumble topping in one of your baking pans. You should have about 6 cookies per pan. Sprinkle a few extra chocolate chips on top of each cookie for added richness and visual appeal.
Bake for 12-15 minutes until the edges of the brownie bases are set and the tops are golden brown. The centers should still look slightly underdone—they'll continue cooking as they cool. Watch closely after 10 minutes to prevent overbaking, which can make the cookies dry. The cookies are done when a toothpick inserted into the center comes out with a few moist crumbs but no wet batter.
⏰ Step 5: Cool and Finish
Remove the cookies from the oven and let them cool in the pans for 5 minutes. Then transfer them to a wire rack to cool completely. Once cooled, use a small spoon or your finger to gently press the chocolate shells back onto each peanut butter cup. This creates that classic Reese's look while keeping the surprise inside. For extra decadence, dust the tops with a little more powdered sugar before serving.
These cookies are best enjoyed at room temperature, so let them sit for at least 30 minutes before serving. The contrast of the warm, fudgy brownie, the creamy peanut butter filling, and the crispy chocolate cookie crumble is what makes these cookies absolutely irresistible!
Pro Tips For Making Brownie Reese Cup Cookie
- Melt Butter Slowly: I learned this the hard way—dumping cold butter into a hot pan for brownie layers makes the batter seize up like a stubborn mule. Instead, melt the butter over medium-low heat until it’s just shimmering (not brown), then let it cool for 2 minutes before mixing. That tiny pause keeps the batter smooth and prevents a greasy mess in your cookies.
- Sift That Cocoa: That unsweetened cocoa powder? It’s not all created equal, and clumps make your cookies dense and uneven. Sift it directly into your mixing bowl—no need to measure afterward—then lightly whisk it with the flour before adding wet ingredients. This ensures every bite gets that rich, even chocolate flavor without dry pockets.
- Don’t Overbake the Centers: The Reese cups are supposed to stay gooey, not turn into hockey pucks. Pull your cookies when the edges are set but the middle still jiggles slightly (about 2–3 minutes after the edges look done). If you’re nervous, cut into one—it should look underdone inside, like a thick pudding. Overbaking kills the magic.
- Chill the Dough: I used to rush this, and my cookies always spread into sad, flat pancakes. After mixing, pop the dough in the fridge for at least 30 minutes (or up to 24 hours if you’re planning ahead). The cold firmness keeps the shape intact, and the flavor develops deeper—like letting wine breathe, but for dessert. Yes, even if you’re impatient like me.
Health benefits of these flavors
Sweet Energy Boost
These cookies pack a satisfying dose of natural sugars from the brownie base, peanut butter, and chocolate, providing a quick energy lift perfect for post-dinner cravings. The combination of carbohydrates (from flour and sugar) and protein (from peanut butter) creates a balanced treat that won’t leave you crashing.
I notice my energy levels stay steady for hours after enjoying one—ideal for late-night dessert lovers. 💪
Peanut Power
The peanut butter in Reese’s cups delivers healthy fats and plant-based protein, both essential for satiety and muscle repair. A single serving contains about 7 grams of protein, making this dessert surprisingly more nutritious than it appears.
The peanuts also provide vitamin E and magnesium, which support skin health and energy metabolism. Trust me, this isn’t just empty sugar—it’s a sneaky nutrient boost!
Chocolate Antioxidants
The unsweetened cocoa powder and semisweet chocolate chips contribute flavonoids, powerful antioxidants that combat oxidative stress in your body. Dark chocolate (like the cocoa used here) has been linked to improved heart health and cognitive function.
For maximum benefits, opt for 70% cocoa or higher—though this recipe still delivers great flavor with standard cocoa powder. 🍫
Crunchy Texture Benefits
The cookie crumble topping adds fiber from the crushed cookies, aiding digestion and promoting gut health. The whole wheat flour option (if substituted) would further boost fiber content, helping you feel full longer.
Even with regular flour, the texture contrast makes each bite more satisfying, reducing the urge to overeat. It’s a smart way to enjoy dessert without guilt!
Portion Control Tip
While indulgent, these cookies are best enjoyed in moderation due to their caloric density (about 350-400 calories per serving). To balance the treat, pair with a protein-rich drink like milk or a small Greek yogurt parfait.
I often save one for dessert and skip other sweets that day—this way, I can fully enjoy the rich flavors without overdoing it. 🍽️

Frequently asked questions
Can I make these without Reese's cups?
For a homemade version, melt 1 cup chocolate and mix with 1 cup creamy peanut butter, then chill until firm. Cut into squares to replace the store-bought cups. The texture will be slightly different but still delicious. If you're short on time, try peanut butter-filled chocolate truffles from the baking aisle.
How do I prevent the brownie centers from being too gooey?
Bake them just until the edges are set (12-15 minutes) and let them cool completely before slicing. The centers will firm up as they cool. For extra stability, chill the baked cookies for 2 hours in the fridge before cutting. If they're still too soft, pop them back in the oven for 2-3 minutes at 300°F.
What's the best way to store these?
Keep them in an airtight container at room temperature for up to 5 days. For longer storage, freeze the baked cookies for up to 3 months. Thaw at room temperature for 1-2 hours before serving. The flavors actually meld better over time, making them perfect for making ahead!
Can I make this gluten-free?
Yes! Replace the all-purpose flour with a 1:1 gluten-free baking flour like Bob's Red Mill. Use the same measurements, but add ½ tsp xanthan gum to help bind the dough. For the cookie crumble, use gluten-free chocolate sandwich cookies. The texture will be slightly different but still delicious.
Why did my crumble topping get greasy?
This usually happens if the butter melts too much during baking.
