Preheat your oven to 350F.
In a large mixing bowl, add all of your ingredients into a bowl except your peanut butter and chocolate chips.
Fold in your chocolate chips and pour your batter into a greased 8x8 brownie pan, or line your pan with parchment paper
Using a tablespoon, dollop your peanut butter on your brownies. This doesn’t have to be perfect, but try to not let your dollops touch. Using a chopstick or toothpick, create swirls.
Bake for 11-12 minutes in a 9x9 pan until a toothpick comes out clean. Allow your brownies to cool a bit, cut and enjoy!
