Welcome to My Kitchen Serenity! These amazing peanut butter brownie squares are an easy one pan dessert. There’s just something about that tasty combination of chocolate and peanut butter.
We love all kinds of brownies, really. These fudgy peanut butter brownies in particular are my husband’s favorite. We also love these Blonde Brownies that always get great comments, and my Chocolate Trifle with Brownies and Toffee Bits are regularly requested for all kinds of gatherings.
Dessert bar recipes are a great idea when you need to bake and take. I like anything you can bake in one pan and then cut into squares and pop into your mouth lol. Plus, dessert bars and squares can easily be individually wrapped and placed into lunch boxes, purses, and picnic baskets.
This is a great recipe for beginners and kids, too. Learning how to carefully measure ingredients, mixing them up, and following directions are essential kitchen skills. Baking can be lots of fun and rewarding with a sense of accomplishment! Eating the finished recipe is the best part!
please refer to the printable recipe card for a complete list of ingredients and step by step directions.
The chocolate brownie layer is made from flour, butter, sugar, eggs, vanilla extract, and salt. These ingredients give the brownies a rich fudgy flavor and texture.
The peanut butter brownie layer is made from flour, butter, sugar, peanut butter, egg, vanilla extract, baking powder, and salt.
The directions are really quite simple. Mix all the ingredients for the peanut butter brownie layer.
Mix all the ingredients for the chocolate brownie layer.
Spread the peanut butter layer on the bottom of an 8-inch by 8-inch pan.
Spread the chocolate layer on top of the peanut butter layer.
Bake and let cool for a few minutes.
Line the bottom of an 8” x 8” pan with parchment paper and spray with non-stick cooking spray. This makes for super easy removal of the brownies. I like to use the pre-cut parchment paper when I have some on hand. Otherwise, it’s not hard to cut your own to fit your pan. You can find this pre-cut parchment paper for square pans on Amazon.
For the brownie layer, do not over mix the batter or the brownies will turn out cake-like.
