Ingredients

Scale

For the Brownie Base:

1 box brownie mix (plus ingredients listed on the box, usually eggs, oil, and water)

Alternative: If you prefer homemade brownies, you can replace the boxed mix with a simple homemade brownie batter using flour, cocoa powder, sugar, butter, eggs, and vanilla extract.

For the Peanut Butter Layer:

2 cups powdered sugar
½ cup butter, softened
1 cup creamy peanut butter

Alternatives: If you have a peanut allergy or prefer a different flavor, almond butter or sunflower seed butter can be used instead.

For the Chocolate Topping:

1 cup milk chocolate chips
6 tablespoons butter

Instructions

Step 1: Prepare and Bake the Brownie Base

Preheat the oven according to the brownie mix instructions.
Grease a 9×13-inch baking pan or line it with parchment paper for easy removal.
In a mixing bowl, prepare the brownie batter according to the package instructions.
Pour the batter into the prepared baking pan and spread it evenly.
Bake the brownies according to the time specified on the box. The exact baking time may vary depending on the brand. To check for doneness, insert a toothpick into the center—if it comes out with a few moist crumbs, the brownies are ready.
Allow the brownies to cool completely before adding the next layer.

Step 2: Make the Peanut Butter Layer

In a medium-sized bowl, combine powdered sugar, ½ cup softened butter, and peanut butter.
Mix well until fully incorporated. The consistency should be similar to playdough, firm but easy to spread.
Using your hands or a spatula, gently press the peanut butter mixture evenly over the cooled brownies. A light dusting of powdered sugar on your hands can prevent sticking.

Step 3: Prepare the Chocolate Topping

In a small saucepan over low heat, melt chocolate chips and 6 tablespoons of butter, stirring occasionally.
Once smooth and fully melted, remove from heat.
Immediately pour the melted chocolate over the peanut butter layer, spreading evenly with a spatula.
Let the brownies cool at room temperature until the chocolate sets. If you are in a hurry, placing the pan in the refrigerator for about 30 minutes will help speed up the process.

Notes

Brownies Not Baking Evenly: If the edges cook faster than the center, try reducing the oven temperature slightly and baking for a longer time. Using a glass or light-colored metal pan can also help distribute heat more evenly.
Peanut Butter Mixture Too Sticky: If the peanut butter layer is sticking to your hands, dust them lightly with powdered sugar or chill the mixture for a few minutes before handling.
Chocolate Topping Not Spreading Smoothly: Melt the chocolate over low heat and stir continuously to prevent burning. If it thickens too quickly, add a teaspoon of melted butter or coconut oil to smooth it out.
Chocolate Cracks When Cutting: Let the brownies come to room temperature before slicing to prevent the chocolate from breaking. Running a knife under warm water before cutting can also help achieve cleaner slices.
