Peanut Butter Cup Brownie Squares

Peanut Butter Cup Brownie Bars by Pixie Dust Kitchen

One of my favorite recipes yet… brownie peanut butter cup bars.

The idea of these came out of having a 3lb jar of peanut butter to get rid of paired with a craving for brownies. I also had some white chocolate chips and sprinkles, so I decided to make a peanut butter cup style brownie bar with three wonderful layers:

1. Fudgy Brownie Crust: I adapted Ashton from Something Swanky’s go-to brownie recipe and pressed into a 9×9 pan. They’re extra most from the use of olive oil and full of chocolate flavor by using equal parts cocoa powder and flour.

2. Peanut Butter Cup Filling: By mixing together creamy Peanut Butter and powdered sugar with a splash of vanilla extract, we’re creating a peanut butter filling very similar to what you would find in a Reese’s Peanut Butter cup

3. White Chocolate and Sprinkles top: To top these brownies, you are going to melt 1 and 1/2 C white chocolate chips and and spread over the bottom two layers, and top with sprinkles. Once you let it set in the freezer Moncler outlet for 20 minutes, you can go ahead and dig in!

These bars are stuffed with some of my favorite things- fudgy brownies, peanut butter, and sprinkles.

Here’s a tip for cutting the bars with the hardened chocolate top: Use a large, sharp knife. Press down and try to cut all at once. This not only makes it easier to cut through the chocolate, but also keeps it from breaking as much as it would making a bunch of smaller cuts with a smaller knife “dragging” through the brownies.

This is one of the most moist, fudgy, brownie recipes I’ve ever had, and stuffing it with peanut butter, sprinkles, and toping with white chocolate is one of the best combos ever! Run to the kitchen and make these today!
