Instructions
Preheat the oven to 350 degrees. Spray two mini muffin tins with cooking spray.
Combine sugar, softened butter, and water in a microwave-safe glass bowl. Cook on high for about 45 seconds or until butter is melted. Stir in ¾ cup semi-sweet chocolate chips until they are melted.
Stir in the egg and vanilla extract, mix until well combined.
Mix the flour and baking soda, and stir until combined.
Add the flour mixture to the melted butter mixture, and stir until well combined.
Allow the batter to cool to room temperature–it takes just a few minutes. Once the batter is cool, stir in ¾ cup milk chocolate chips and the remaining ¼ cup of semi-sweet chocolate chips.
Spoon batter evenly into the prepared mini muffin tins.
Bake for 8-9 minutes or until the top is set and a tester inserted into the center comes out slightly wet.
After brownies are out of the oven, wait for centers to fall, about 15 minutes. If the centers don't fall, tap the centers with the back of a teaspoon to make a hole for the peanut butter.
Place peanut butter in a small microwave-safe glass bowl. Microwave on high for 20 seconds, then stir.
While brownies are still warm, spoon about a tablespoon of peanut butter into the center of each brownie.
