Ingredients
Method
- Heat oven to 350F and line an 8x8 pan with parchment.
- Whisk butter and sugar, then beat in eggs and vanilla.
- Fold in cocoa and flour until just combined.
- Stir in one cup of chocolate chips, then spread the batter into the pan.
- Scatter the remaining chips over the top and bake 28 to 30 minutes.
- Cool completely before slicing.
Notes
A mix of dark and semisweet chips gives the best chocolate depth.
