Our chocolate Peanut Butter Brownies are the ultimate treat for chocolate and peanut butter lovers! We're talking rich, chewy, and covered in a creamy peanut butter frosting, then chocolate glaze, and Reese’s peanut butter cups in every bite.
One-Two punch Chocolate Peanut Butter Brownies
I'm sure we can all agree the chocolate and peanut butter combo in this Peanut Butter Brownies recipe is absolutely unbeatable. They're like a homemade Reese’s in brownie form, and always a huge hit whenever I make them.
I actually prefer to make these brownies a day in advance, because I think they taste even better after they've had time to chill and set in the fridge.

How to make Peanut Butter Brownies:
Make Brownies: Combine granulated sugar, brown sugar, and melted butter until smooth, then mix in the eggs, egg yolk, milk, and vanilla. In a separate bowl, whisk together the dry ingredients and add them to the wet mixture, stirring just until combined. Spread the thick batter into a greased 9×13-inch pan and bake at 350°F for 35–45 minutes, or until a toothpick inserted in the center comes out clean. Let the brownies cool completely.
Peanut Butter Frosting: Beat together butter and peanut butter until creamy, then mix in powdered sugar, vanilla, and a splash of milk until light and fluffy. Spread evenly over the cooled brownies and refrigerate.
Add Melted Chocolate: Melt chocolate chips and butter in the microwave until smooth, let cool slightly, then pour over the peanut butter frosting. Top chocolate and peanut butter brownies with chopped Reese’s and chill until the chocolate sets.
