Ingredients & Substitutions

These are the main ingredients and substitutions for chocolate peanut butter brownies. Scroll down to the recipe card for full ingredients list and instructions.

Combine creamy all natural peanut butter and powdered sugar for the filling. Use an all natural creamy peanut butter made from only peanuts and salt. Do not use one with added oils or sugars.

Any type of chocolate chips can be used. I recommend using chocolate chips that you enjoy the taste of. The chocolate is a huge flavor. If using sugar free chocolate, the tops of the brownies will not be as shiny.

Granulated sugar adds sweetness. For refined sugar free, use coconut sugar.

Two eggs help bind the brownies together. For Vegan and egg free, make these Vegan Brownies.

Cocoa powder adds even more chocolate flavor. Use regular or dark cocoa powder.

Vanilla extract adds a great homemade flavor.

Both regular all purpose flour and gluten free 1 to 1 flour work well. If needed, substitute cornstarch or tapioca flour in an equal amount.

Use creamy all natural peanut butter for the swirl. The only ingredients should be peanuts and salt. This version is easily pourable and runny.

How to Make

Step 1

First, preheat oven to 350 degrees Fahrenheit. Line an 8 inch by 8 inch square pan with parchment paper.

Step 2

Make peanut butter filling. Add creamy peanut butter and powdered sugar to a bowl. Stir to combine. Set aside.

Step 3

In another bowl, add melted butter and chocolate chips. Stir until chocolate is completely melted and creamy. If needed, microwave quickly to melt.

Step 6

Add in cocoa powder, vanilla and flour. Stir to combine.

Step 7

Pour half of the brownie batter into the lined pan.

Drop the peanut butter filling in dollops on top. Use your hands to spread out into an even layer. This does not have to look perfect.

Step 9

Then, pour remaining brownie batter on top.

Step 10

Pour ⅓ cup creamy peanut butter all over the top. Use a knife or toothpick to swirl.

Step 11

Bake for 28 to 30 minutes or until middle looks set. The brownies should no longer jiggle.
