How to Make Easy Peanut Butter Brownies
Step 1: Prepare the Oven
Preheat the oven to 350°F (175°C).
Line a 9×13-inch baking pan with parchment paper.
Step 2: Make the Brownie Batter
Whisk together the melted butter, granulated sugar, and brown sugar.
Add the eggs and vanilla extract.
Mix in the cocoa powder.
Fold in the flour, baking powder, salt, and chocolate chips until just combined.
Spread the batter evenly into the prepared pan.
Step 3: Prepare the Peanut Butter Swirl
In a small bowl, stir together the peanut butter, powdered sugar, and melted butter until smooth.
Drop spoonfuls evenly over the brownie batter.
Use a butter knife to gently swirl the peanut butter through the brownie batter without overmixing.
Step 4: Bake
Bake for 30 to 35 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs.
Allow the brownies to cool completely before slicing.
Expert Tips
These simple tips will help your Easy Peanut Butter Brownies turn out rich, fudgy, and perfectly swirled every time.
Use Creamy Peanut Butter
Regular creamy peanut butter creates the smoothest swirls. Natural peanut butter tends to separate during baking and won’t produce the same texture.
Don’t Overmix the Swirls
Use a butter knife or skewer to make just a few gentle figure-eight motions. Overmixing blends the peanut butter into the batter instead of creating beautiful swirls.
Slightly Underbake
Remove the brownies when a toothpick comes out with a few moist crumbs. They will continue setting as they cool, giving you a fudgy texture.
Cool Completely Before Slicing
Let the brownies cool completely before cutting. This helps them hold their shape and creates clean bakery-style squares.
If you’re a fan of rich chocolate desserts, our Easy Brownie Cheesecake Bars are another decadent recipe you’ll love.
Common Mistakes
Using Natural Peanut Butter
Natural peanut butter can separate while baking and may create oily patches instead of creamy swirls.
Overbaking
Too much time in the oven can make the brownies dry instead of soft and fudgy.
Overmixing the Batter
Mix only until the flour disappears. Overmixing develops gluten and makes brownies less tender.
Cutting While Warm
Warm brownies tend to crumble. Cooling them completely produces cleaner slices.
Easy Variations
These Easy Peanut Butter Brownies are easy to customize.
Peanut Butter Cup Brownies
Fold chopped peanut butter cups into the brownie batter before baking.
Triple Chocolate Peanut Butter Brownies
Add white chocolate and milk chocolate chips along with the semi-sweet chocolate chips.
Salted Peanut Butter Brownies
Sprinkle flaky sea salt over the brownies just before baking for a sweet-and-salty finish.
Peanut Butter Cheesecake Brownies
Swirl sweetened cream cheese into the batter along with the peanut butter.
Crunchy Peanut Butter Brownies
Use crunchy peanut butter for added texture and roasted peanut flavor.
What to Serve With Easy Peanut Butter Brownies

Serve them warm with a scoop of vanilla ice cream or a dollop of freshly whipped cream for an indulgent dessert.
