How to Cook Peanut Butter Cup Brownies

Baking Peanut Butter Cup Brownies is an enjoyable and straightforward process. You’ll love how easy it is to create this decadent treat. Let’s get started with the detailed steps to ensure your brownies turn out perfectly!
Preheat your oven to 350°F. This step is crucial as it ensures even baking. While the oven is heating up, grab an 8-inch square baking pan and spray it with nonstick cooking spray to prevent sticking.
In a microwave-safe bowl, combine semi-sweet chocolate chips and unsalted butter. Microwave for about 45 seconds, then give it a good stir. If the mixture isn’t mostly melted, microwave it for an additional 20 seconds. Stir until the mixture is completely smooth.
Once your chocolate and butter mixture is ready, whisk in the cocoa powder and instant espresso powder. Mixing these dry ingredients into the warm chocolate will help them dissolve better, enhancing the flavor.
In a separate bowl, whisk together the eggs, granulated sugar, vanilla extract, creamy peanut butter, and salt. You want everything to be well combined; this will create a smooth batter.
Now, gradually whisk the warm chocolate mixture into the egg mixture. The warmth of the chocolate will help to temper the eggs, preventing them from scrambling.
With your chocolate and egg mixtures combined, gently stir in the all-purpose flour until just incorporated. Be careful not to overmix, as this can lead to tougher brownies.
Finally, fold in the chopped Reese’s peanut butter cups. This is where the magic happens! The pieces will melt slightly during baking, providing delightful pockets of peanut butter goodness.
Pour the brownie batter into the prepared baking pan, spreading it evenly. Use a rubber spatula to level the surface, ensuring even baking.
Place the pan in the preheated oven and bake for approximately 35 to 40 minutes. The brownies will puff slightly, and a toothpick inserted into the center should come out mostly clean.
Once baked, remove the brownies from the oven and allow them to cool in the pan for about 2 hours at room temperature. This cooling time is essential for achieving the perfect texture.
Once cooled, cut the brownies into 1-inch squares and serve. Store any leftovers in a tightly sealed container at room temperature for up to 3 days.
Things Worth Knowing
- Use high-quality chocolate: The flavor of your brownies will be influenced by the quality of the chocolate you use. Opt for good-quality semi-sweet chocolate chips.
- Check for doneness: The toothpick test is essential. You want the brownies to be set but still fudgy, so they should not be overbaked.
- Let them cool: Allowing the brownies to cool completely before cutting helps them maintain their shape and texture.
- Experiment with toppings: Consider adding a drizzle of chocolate or a sprinkle of sea salt on top for an extra flavor boost!
Ways to Customize

If you’re looking to add a personal touch to your Peanut Butter Cup Brownies, here are some fantastic ways to customize this recipe!
- Add nuts: For a delightful crunch, consider adding chopped walnuts or pecans to the batter.
- Use different chocolate: Experiment with milk chocolate or dark chocolate chips for a different flavor profile.
- Mix in more candies: Try adding mini chocolate chips or even M&M’s for extra sweetness and color.
- Gluten-free option: Substitute the all-purpose flour with gluten-free flour to make this recipe suitable for those with gluten sensitivities.
- Make it vegan: Swap the eggs with flaxseed meal and use dairy-free chocolate and peanut butter.
- Try different nut butters: While creamy peanut butter is delicious, consider using almond butter or cashew butter for a unique twist.
- Serve warm: For an indulgent treat, serve the brownies warm with a scoop of vanilla ice cream on top.
