Ingredients
Method
- Preheat the oven to 350°F and line a pan with parchment.
- Whisk the butter, sugar, and eggs until thick and glossy.
- Fold in the flour and cocoa to form a rich batter.
- Stir in both kinds of chocolate chips.
- Spread into the pan and bake for 30 to 32 minutes until just set.
- Cool fully, then chill briefly for a dense, truffle-like texture.
Notes
Slightly underbake for that gooey truffle center everyone fights over.
