• Here’s everything you need to make these indulgent treats!

- Unsalted butter – Adds moisture and richness; you can use salted butter if desired, just adjust the salt in the recipe.
- Eggs (room temperature) – Helps bind all ingredients together; always use room temperature eggs for better mixing.
- Vanilla extract – Enhances the flavor profile; opt for pure vanilla extract for the best results.
- White granulated sugar – Sweetens the brownies; feel free to swap it with brown sugar for added depth.
- All-purpose flour – Provides structure to the brownies; gluten-free flour can be a suitable substitute for a gluten-free version.
- Dutch process cocoa powder – Deepens the chocolate flavor; unsweetened cocoa can work as a good alternative.
- Salt – Balances the sweetness and enhances flavors; essential for a well-rounded taste.
For the Delicious Mix-ins

Step‑by‑Step Instructions for Peanut Butter Cup Brownies
Step 1: Prepare Baking Pan
Preheat your oven to 325°F (163°C). While it heats, grab an 8×8 baking pan and spray it with non-stick spray. To ensure easy removal later, line two sides of the pan with parchment paper, allowing excess to hang over the edges. This will help you lift out the brownies effortlessly once they’re baked.
Step 2: Melt Butter and Chocolate
In a large heatproof bowl set over a saucepan of simmering water (double boiler), combine semi-sweet chocolate chips and unsalted butter. Stir gently until the mixture is completely melted and smooth, about 5-7 minutes. Once melted, remove from heat and let it cool for 5 minutes before moving to the next step to avoid cooking the eggs later.
Step 3: Mix Dry Ingredients
While the chocolate mixture cools, take a medium bowl and sift together the all-purpose flour, Dutch process cocoa powder, and salt. This process aerates the ingredients, ensuring an even distribution in your rich and fudgy peanut butter cup brownies. Set this bowl aside and prepare for the next exciting blend!
Step 4: Beat Eggs
In a large mixing bowl, use a mixer fitted with a whisk attachment to beat the room temperature eggs, sugar, and vanilla extract together. Whip everything on medium speed for about 5 minutes, until the mixture turns pale, thick, and slightly frothy. This step is crucial for creating that beautiful crackly top on your brownies.
Step 5: Combine Mixtures
Gently stir the cooled chocolate mixture into the whipped egg mixture using a spatula, being careful not to deflate the whipped eggs. Once combined, slowly and carefully fold the sifted dry ingredients into this wet mixture, ensuring not to overmix. You want your peanut butter cup brownies to stay fudgy and delicious!
Step 6: Add Fillings
After the batter is smooth and well combined, fold in the chopped Reese’s peanut butter cups and mini chocolate chips. These mix-ins will create delicious pockets of creamy peanut butter and extra chocolatey flavor throughout the brownies. Make sure they are evenly distributed for the ultimate treat!
Step 7: Bake the Brownies
Pour the brownie batter into your prepared baking pan, using a spatula to spread it evenly. Bake in the preheated oven for 40-45 minutes. The edges should look set while a toothpick inserted into the center will come out with a few moist crumbs. This indicates a perfect fudgy texture.
Step 8: Cool and Top
Once baked, let the brownies cool in the pan for about 10 minutes. While they’re still warm, scatter additional peanut butter cups on top, allowing them to melt slightly. Afterward, transfer to a wire rack or let cool completely in the pan before slicing into squares; this ensures clean edges when serving.
Step 9: Decorate Cookies
For a decorative touch, take your Nutter Butter cookies and stick miniature pretzels onto the top as antlers. Then, attach candy eyes and place a red round candy for the nose. These delightful reindeer cookies can be placed on each sliced brownie, adding a fun and festive aesthetic to your stunning peanut butter cup brownies!

How to Store and Freeze Peanut Butter Cup Brownies
Room Temperature: Store brownies in an airtight container at room temperature for up to 5 days to maintain their richness and fudginess.
Fridge: If you want to keep them fresh for a longer time, you can refrigerate the brownies for up to 7 days, but be aware they might become a bit denser.
Freezer: For longer storage, freeze the brownies for up to 30 days. Wrap them tightly in plastic wrap and place them in a freezer-safe bag to prevent freezer burn.
Reheating: Thaw frozen brownies at room temperature for about an hour before serving. You can warm them slightly in the microwave for 10-15 seconds to revive their gooey texture.
Make Ahead Options
These Rich & Fudgy Peanut Butter Cup Brownies are perfect for meal prep enthusiasts!

If you prefer, you can also bake the brownies and store them in an airtight container at room temperature for up to 3 days. Just remember to top them with additional peanut butter cups while they’re still warm for maximum deliciousness. To enjoy, simply slice and serve, and you’ll have a decadent treat ready for any occasion with minimal last-minute effort!
