These Peanut Butter Swirl Brownies are the perfect combination of chocolate and peanut butter. My homemade brownies are studded with peanut butter chips and swirled with creamy peanut butter. A decadent dessert that will be devoured in minutes!
Preheat oven to 350°F and line a 8x8 inch baking dish with parchment paper leaving an inch overhang on 2 opposite sides. Or grease the pan well with non-stick cooking spray.
Melt the butter in a small saucepan over low heat on the stove or in a large glass mixing bowl in the microwave.
Whisk in eggs and vanilla extract until the batter is smooth and airy.
Using a rubber spatula or wooden spoon, fold in the all purpose flour.
Add the peanut butter chips and fold in until evenly incorporated.
Evenly spread the brownie batter in the prepared baking dish.
In a microwave safe bowl or pourable measuring cup, warm the peanut butter for 15-20 seconds.
Pour or dollop the peanut butter in rows on top of the brownie batter. Using a butter knife or chop stick, drag it through the peanut butter and brownie batter starting with the top rows, going back and forth through each row only once. Then drag through the columns only once as well. It will create a wonderful swirl.
Bake the brownies in preheated oven for 25-30 minutes or until a toothpick inserted in center comes out with only a few damp crumbs. Don't overbake the brownies.
Let brownies cool for at least 20 minutes before removing from pan. Cool completely before storing.
