Ingredients
Method
- Heat oven to 350F and line a square pan with parchment.
- Whisk butter, sugar, eggs, vanilla, cocoa, and flour into a batter.
- Fold in most of the chocolate chips and spread into the pan.
- Swirl the peanut butter on top and scatter the remaining chips.
- Bake 28 to 30 minutes until set, then cool before slicing.
Notes
A handful of chips on top gives those bakery-style melty pools.
