Desserts
This brownie Reese cup cookie recipe delivers the ultimate dessert trifecta—fudgy brownie layers, gooey peanut butter rivers, and crisp edges all in one cookie. The secret lies in baking a rich brownie base, embedding Reese’s cups midway, then finishing with a buttery cookie crust that holds everything together.
I’ve perfected this technique over years of testing, ensuring each bite has that perfect balance of textures and flavors.
The process starts with a classic brownie dough, pressed into the pan and partially baked to create a sturdy foundation. Then comes the magic: pressing Reese’s cups into the warm brownie layer, allowing their peanut butter centers to melt slightly and create those signature rivers when baked.
Finally, a cookie dough topping seals the deal, creating a crisp exterior that contrasts beautifully with the fudgy interior.
What you’ll end up with is a dessert that looks impressive but comes together with simple techniques—no fancy equipment required. The combination of chocolatey brownie, creamy peanut butter, and buttery cookie creates a flavor profile that’s impossible to resist.
These cookies stay fresh for days, making them perfect for holiday gatherings or satisfying a late-night craving.
Serve warm with a scoop of vanilla ice cream or dust with powdered sugar for an extra touch of elegance. The contrast of warm cookies and cold ice cream takes this treat to the next level. Let’s get baking!
Ingredients for brownie reese cup cookie
Twelve Reese's cups, rich chocolatey brownie dough, and a buttery cookie crust—this trifecta delivers next-level cookie magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Reese's Peanut Butter Cups 🍫 | 12 whole | Mini or regular size, unopened |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for brownie dough |
| Granulated Sugar 🍚 | 1 ½ cups | White or brown for depth |
| Packed Brown Sugar 🍚 | ½ cup | For chewy texture |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality |
| All-Purpose Flour 🌾 | ¾ cup | Sifted for lightness |
| Cocoa Powder 🍫 | ½ cup | Natural, unsweetened |
| Baking Powder 🧂 | ½ tsp | Aluminum-free preferred |
| Salt 🧂 | ¼ tsp | Fine sea salt |
| Semisweet Chocolate Chips 🍫 | 1 cup | Enjoy Life brand for allergies |
| Peanut Butter 🥜 | ½ cup | Creamy, natural style |
| All-Purpose Flour 🌾 | ½ cup | For cookie topping |
| Powdered Sugar 🍚 | ¼ cup | For dusting |
The Reese's cups are non-negotiable here—mini size works perfectly for even distribution, but regular size cuts in half work too. Walmart or Target always have them stocked, and I swear by the mini size for holiday baking. For the brownie base, Hershey's Special Dark cocoa powder gives that deep chocolate flavor, but Dutch-processed works too. The peanut butter? Jif or Smucker's creamy are my go-tos—just make sure it's natural with no added oils. And the butter? Plugrá or Land O'Lakes unsalted—never salted for perfect balance.
No Reese's cups? Homemade peanut butter cups (melt chocolate, mix with peanut butter, chill) work in a pinch. Short on cocoa powder? Melted dark chocolate at 1:1 ratio saves the day. The cookie topping can be swapped for crushed Oreos or graham crackers if you're in a hurry. For the peanut butter in the dough, sunflower seed butter is a great nut-free alternative. And if you're worried about the cookies spreading too much, chill the dough for 30 minutes before baking—trust me on this!
These cookies stay fresh for 5-6 days in an airtight container at room temperature, but I always make extra to freeze. Portion into single-serving bags for easy reheating—just 10 seconds in the microwave. For serving, I like to dust with powdered sugar right after baking while they're still warm. Pair with vanilla ice cream or a scoop of Ben & Jerry's Phish Food for the ultimate combo. The peanut butter rivers? Worth the extra minute of pressing—every bite is pure magic.
Why You'll Love This Recipe
- No-Fuss Mix-In: I swear by the 5-minute prep here—just chop the cups into tiny chunks, fold them into the dough, and bake. No rolling, no fuss, no waiting for fillings to set. That chocolatey peanut butter magic happens while you’re mixing.
- Double Trouble Crunch: The contrast is what makes this recipe dangerous: the fudgy, crackly edge of the brownie meets the creamy Reese’s shards in every bite. Honestly, I’ve never met a cookie that balances rich and crunchy this well—it’s like dessert hugged a brownie.
- Party in a Box: These disappear at gatherings, but the best part? They’re just as good reheated the next day. Pack them in a tin for potlucks, freeze half for lazy mornings, or hand them out as favors. (Yes, even on a Tuesday night.)
- Budget Binge-Worthy: A single bag of Reese’s and a stick of butter stretch to dozens—way cheaper than buying pre-packaged desserts. Plus, the eggs and sugars are pantry staples, so you’re basically making gold from what you already have. My wallet thanks me every time.
Step-by-step instructions for brownie Reese cup cookie recipe
Here's how to create decadent cookies with fudgy brownie centers and peanut butter rivers—every bite is pure indulgence!
Prepare the Brownie Base
Preheat your oven to 350°F and line a baking sheet with parchment paper. In a large bowl, cream together the 1 cup unsalted butter and both sugars until light and fluffy—about 3-4 minutes. This step is crucial for achieving that perfect chewy texture.
Add the 2 whole large eggs, one at a time, mixing well after each addition. Stir in the 1 teaspoon vanilla extract, then sift in the 0.75 cup all-purpose flour, 0.5 cup cocoa powder, 0.5 teaspoon baking powder, and 0.25 teaspoon salt. Mix just until combined—overmixing develops gluten and makes the cookies tough.
Fold in Chocolate and Shape Dough
Gently fold in the 1 cup semisweet chocolate chips using a spatula. Divide the dough into 12 equal portions (about 1.5 ounces each) and roll each into a ball. Flatten each ball slightly into a 1-inch thick disc—these will be your brownie centers.
Place the discs on the prepared baking sheet, spacing them about 2 inches apart. Bake for 10-12 minutes until the edges are set but the centers still look slightly underdone. You want them fudgy, not fully baked—this ensures the perfect texture when combined with the peanut butter cookie layer.
Make the Peanut Butter Cookie Topping
While the brownie discs cool slightly, prepare the peanut butter cookie mixture. In a separate bowl, combine the 0.5 cup peanut butter, 0.5 cup all-purpose flour, and 0.25 cup powdered sugar. Mix until smooth and well incorporated—this will form the creamy peanut butter rivers that bind everything together.
Drop about 1 teaspoon of the peanut butter mixture onto the center of each cooled brownie disc. Use a toothpick to create small "rivers" radiating from the center—this ensures the peanut butter spreads evenly when baked.
Assemble and Bake the Cookies
Place each 12 whole Reese's Peanut Butter Cup on top of the peanut butter rivers, pressing down gently to secure. Bake at 350°F for an additional 8-10 minutes until the peanut butter is set and the edges are golden. The peanut butter should look glossy and slightly puffed.
Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack. The contrast between the fudgy brownie base, creamy peanut butter rivers, and the classic Reese's filling creates the ultimate texture combination—each bite is a perfect balance of chewy, crunchy, and creamy!
Pro Tips For Making Brownie Reese Cup Cookie
- CHOP CUPS SMALL: Reese’s cups are stubborn—don’t just break them in half. Grab kitchen shears or a sharp knife and snip them into tiny, uneven bits (think rice-sized). This ensures even melting and distribution in the dough, so you don’t end up with giant peanut butter pockets. I learned this the hard way when my first batch had a single whole cup that stayed cold and chewy.
- MELT BUTTER LOW: You’re not making caramel—bring that butter to 160°F (71°C) max in a double boiler or microwave in 20-second bursts. Overheating turns it nutty and burns the peanut butter flavor before it even hits the dough. I used to rush this, and the cookies always tasted off. Patience here = richer taste.
- DON’T OVERMIX: The moment the dry ingredients disappear, stop stirring. One more turn and you’ll develop gluten like you’re making bread, not fudgy cookies. The dough should look shaggy and thick—like wet sand. I’ve seen people mix until it’s smooth, and the result? Dense, cakey cookies instead of the chewy, crackly texture you want.
- USE ROOM-TEMP EGG: Cold eggs from the fridge cut the butter in the dough, forcing you to work harder and risk uneven texture. Let them sit in warm water for 5 minutes (or use the hand-hot trick: hold one in your palm for 30 seconds). The dough will come together faster, and the cookies spread more evenly. Trust me, this small step saves headaches later.
Health benefits of brownie reese cup cookie
Energy Boost Combo
This dessert packs a surprising nutritional punch with its peanut butter and dark chocolate combo. The Reese’s cups contribute healthy fats from peanuts, which provide sustained energy and help keep you full longer.
A single serving (about 3 cookies) delivers roughly 150 calories and 8 grams of protein, making it a more satisfying treat than many store-bought cookies. 💪
Antioxidant-Rich Chocolate
The cocoa powder and semisweet chocolate chips in the brownie layer are loaded with flavonoids, powerful antioxidants that support heart health and reduce inflammation. Dark chocolate (like the Hershey’s Special Dark used here) has even higher antioxidant levels than milk chocolate.
These compounds also help improve blood flow and cognitive function—so you’re basically feeding your brain while indulging! 🧠
Protein for Muscle Recovery
Peanut butter isn’t just delicious—it’s a protein powerhouse. The ½ cup of creamy peanut butter in both the brownie and cookie layers provides about 8 grams of protein per serving.
This makes these cookies a great post-workout snack, especially when paired with a banana or Greek yogurt for extra protein. The eggs in the brownie base add another 12 grams of complete protein, rounding out this nutrient-dense treat.
Fiber for Digestion
While these cookies are indulgent, they’re not devoid of fiber! The all-purpose flour and cocoa powder contribute about 3 grams of fiber per serving, supporting healthy digestion.
The peanut butter also adds a small amount of fiber, plus vitamin E and magnesium, which help with muscle function and stress reduction. For an extra fiber boost, try swapping ¼ cup of the all-purpose flour for whole wheat flour—you won’t taste the difference! 🌾
Healthy Fat Balance
The unsalted butter and peanut butter in this recipe provide heart-healthy monounsaturated fats, which help lower bad cholesterol when consumed in moderation. These fats also enhance the absorption of fat-soluble vitamins like vitamin A and vitamin E from the other ingredients.
Just be mindful of portion sizes—these cookies are rich, so 2-3 per serving keeps them a treat rather than a daily staple. 🍫
Smart Indulgence Tips
Want to make this dessert even healthier? Use natural peanut butter (no added sugars or oils) and dark chocolate chips with at least 60% cocoa. For a lighter version, reduce the sugar by 2 tablespoons and add 1 teaspoon of vanilla extract to compensate for the sweetness.
Pair with a small scoop of vanilla ice cream or fresh berries to balance the richness and add vitamins. The key is moderation—these cookies are a guilt-free splurge when enjoyed mindfully! ✨

Frequently asked questions
Can I make these without Reese's cups?
For a homemade version, melt ½ cup semisweet chocolate with ½ cup creamy peanut butter, chill until firm, then cut into 12 squares to replace the Reese's cups. Press them into the warm brownie layer just like the originals—they'll melt slightly and create those same delicious rivers when baked.
Why do my peanut butter rivers disappear?
This usually happens when the brownie base isn't fully cooled before adding the peanut butter. Let the brownie discs cool completely (5-10 minutes) before adding the peanut butter mixture. Also, make sure your peanut butter isn't too runny—if it is, chill it for 15 minutes before using. The rivers should stay put when baked at 350°F for 8-10 minutes.
How do I prevent the cookies from spreading too much?
Chill the peanut butter cookie mixture for 30 minutes before baking, and use a cookie scoop to portion the dough evenly. For extra insurance, place the assembled cookies on a parchment-lined baking sheet and bake at 325°F instead of 350°F—this slower temperature helps them set better without spreading.
Can I make these gluten-free?
Yes! Swap the all-purpose flour for a 1:1 gluten-free baking flour blend (like Bob's Red Mill) and ensure your cocoa powder is labeled gluten-free. The brownie base and cookie topping will both work perfectly with this substitution. For the peanut butter rivers, use the same gluten-free flour blend—just mix it with the peanut butter and powdered sugar as directed.
How long do these stay fresh?
Store in an airtight container at room temperature for up to 5 days, or freeze for 2 months for maximum freshness. To reheat, microwave for 10-15 seconds to restore the peanut butter rivers' gooey texture. For serving, dust with powdered sugar right before eating—it adds a beautiful finish and keeps the cookies from drying out too quickly.
