Peanut Butter Cup Brownie Ingredients
For the Brownie Batter
• Semi-sweet chocolate chips – Provides strong chocolate flavor and moisture; substitute with dark chocolate for a richer taste.
• Butter (unsalted) – Adds richness and tenderness; can be replaced with coconut oil for a dairy-free version.
• Eggs (room temperature) – Essential for structure and leavening; ensure they are at room temperature for best results.
• Vanilla extract – Enhances the overall flavor profile; pure vanilla is preferred for a natural taste.
• White granulated sugar – Sweetens and helps create a fudgy texture; can substitute with brown sugar for a deeper flavor.
• All-purpose flour – Provides structure; for gluten-free, use a 1:1 gluten-free flour blend.
• Dutch process cocoa powder – Adds an intense chocolate flavor without bitterness; substitute with regular cocoa powder if unavailable.
• Salt – Balances sweetness and enhances flavors.
• Reese’s peanut butter cups (miniature, halved) – Provides the signature peanut butter taste; no substitute necessary.
• Mini chocolate chips – Adds extra richness and texture; dark chocolate chips can be used for a different flavor.
For the Decoration
• Nutter Butter cookies – Decorative element resembling reindeer; omit for a simpler brownie or use any cookie for decoration.
• Pretzels (miniature) – Used to create antlers on reindeer cookies; any similar-shaped snack can work.
• Candy eyes – Decorative, whimsical element; could use chocolate chips or similar candies as an alternative.
• Red round candies (mini M&M’s) – Acts as the reindeer’s nose; any red candy can substitute.
Step‑by‑Step Instructions for Peanut Butter Cup Brownies
Step 1: Preheat and Prepare the Baking Pan
Start by preheating your oven to 325°F (163°C). Grease an 8×8-inch baking pan with non-stick spray, then line two sides with parchment paper, allowing excess to hang over the edges. This will help you lift the brownies out easily after baking. Set the pan aside as you get ready to make the fudgy brownie batter.
Step 2: Melt Chocolate and Butter
In a double boiler, combine semi-sweet chocolate chips and unsalted butter. Stir the mixture occasionally until everything is fully melted and smooth, which should take about 5-7 minutes. Once melted, remove it from the heat and let it cool for about 5 minutes before mixing in the next ingredients to ensure the chocolate doesn’t cook the eggs.
Step 3: Mix the Dry Ingredients
In a separate bowl, sift together the all-purpose flour, Dutch process cocoa powder, and a pinch of salt. This step is crucial for preventing lumps and ensuring a silky texture in your Peanut Butter Cup Brownies. Set this bowl aside, as you will soon combine it with the wet ingredients for a deliciously rich batter.
Step 4: Whip the Eggs and Sugar
Using an electric mixer, whip together the room temperature eggs, granulated sugar, and vanilla extract in a large mixing bowl. Beat the mixture on medium-high speed for about 5 minutes until it thickens and turns pale. This aeration is essential for creating that wonderful fudgy texture in your brownies.
Step 5: Combine Wet and Dry Ingredients
Gently fold the melted chocolate and butter mixture into the whipped egg mixture, using a spatula for a seamless incorporation. Next, gently add the sifted dry ingredients to the wet mixture, taking care not to overmix. Stop mixing as soon as there are no dry bits left to maintain that rich, fudgy consistency that Peanut Butter Cup Brownies are known for.
Step 6: Add the Special Ingredients
Carefully fold in the halved Reese’s peanut butter cups and mini chocolate chips, ensuring even distribution throughout the batter. This is where your brownies gain delightful pockets of melted peanut butter and additional chocolatey goodness. Make sure every bite contains the scrumptious mix of flavors that makes these brownies a standout dessert.
Step 7: Bake the Brownies
Pour the brownie batter into the prepared baking pan, spreading it evenly with a spatula. Place it in the oven and bake for 40-45 minutes. You’ll know they’re done when the edges look set, but a toothpick inserted in the center comes out with moist crumbs. Allow the brownies to cool in the pan for about 10 minutes before adding more halved Reese’s cups on top for that extra touch of peanut butter richness.
Step 8: Cool and Decorate
Once the brownies are cool enough to handle, use the parchment overhang to lift them out of the pan. Allow them to cool completely on a wire rack for better slicing. After the brownies have cooled, let your creativity shine by decorating them with Nutter Butter cookies attached with melted chocolate, adding pretzel antlers, candy eyes, and red candies for the noses to create your festive reindeer delights.

Peanut Butter Cup Brownies Recipe FAQs
What is the best way to choose ripe ingredients for peanut butter cup brownies?
Absolutely! For the best results, select fresh, high-quality ingredients. Check your eggs for no cracks and a clean shell. When choosing chocolate chips, look for those with a glossy finish and avoid any with dull spots, as they indicate age. Fresh butter should be soft to the touch, while flour should be free of clumps.
How should I store leftover peanut butter cup brownies?
Very simple! Keep your brownies in an airtight container at room temperature for up to 5 days to maintain their fudgy texture. If you need to store them for longer, consider placing them in the refrigerator for up to 7 days. Just wrap them well to prevent drying out.
Can I freeze peanut butter cup brownies and how?
Yes, you can! To freeze your brownies, allow them to cool completely first. Then, wrap each brownie individually in plastic wrap and place them in an airtight container. They can be frozen for up to 30 days. When you’re ready to enjoy, simply thaw them at room temperature for a couple of hours, and they’ll be as fresh as the day you made them!
What should I do if my peanut butter cup brownies turn out too cakey?
If your brownies come out cakey, it’s likely because they were overmixed or baked for too long. The key to fudgy brownies lies in minimal mixing once the flour is added and careful timing in the oven. Always start checking for doneness at around 40 minutes, as they should still look slightly underbaked when you remove them.
Are peanut butter cup brownies safe for people with nut allergies?
Be cautious! Traditional peanut butter cup brownies contain peanut butter, which is unsafe for those with nut allergies. You may opt for alternatives like sunflower seed butter or almond butter (ensure no cross-contamination in your kitchen if allergies are a concern) to create a nut-free version. As always, reading labels on all ingredients used is crucial.
Can I use other candies instead of Reese’s in my brownies?
The more the merrier! Feel free to get creative with your toppings! Snickers, Twix, or even chopped Oreos can add delicious twists to your brownies. Just make sure whichever candy you choose is evenly distributed throughout the batter to ensure that every bite bursts with flavor.
