- 1 box brownie mix
- 3/4 cup peanut butter, smooth
- About 1 cup pretzels
Preheat oven to 350°F.
Prepare brownie mix to package directions.
Pour the peanut butter into the brownie batter and give it a few quick folds to make a peanut butter swirl. Pour the batter into a 12-inch cast-iron skillet.
Carefully place pretzels on the top of the brownie batter to cover.
Bake for 25-30 minutes.
