I had a box of brownie mix that I wanted to add something to so when I found this recipe via Joy the Baker I decided to give it a try. Joy makes hers from scratch and I would have but I was feeling extra lazy. To make your own, start by making the brownie batter. You can follow Joy's recipe, use a box, or you could try my homemade brownie recipe.
Once you have your brownie batter prepared, pour it into a greased 9x13 pan. Now start on the peanut butter mixture. You will need...
- 4 tablespoons unsalted butter, melted
- 1/2 cup powdered sugar (if you're using a box of brownie mix, I would add less powdered sugar since those mixes are usually extra sweet to begin with)
- 3/4 cup smooth peanut butter
- 1/4 teaspoon salt
- 1/2 teaspoon vanilla extract
Combine all of the ingredients for the peanut butter mixture and pour it over the brownie batter. Swirl it around. Now add your pretzels. You can leave them whole or crunch them up like I did.
Bake them according to the brownie recipe you used but keep in mind that they might take a little longer because of the added ingredients. Take them out of the oven when a toothpick comes out almost clean. Wait for them to cool before cutting them up. Beware, these babies are rich!
