Ingredients
Method
- Preheat oven to 350F and line an 8x8 pan with parchment.
- Whisk butter, sugar, and eggs, then fold in flour and cocoa.
- Stir half the hazelnuts into the batter and spread it in the pan.
- Dollop hazelnut spread over the top, swirl gently, and scatter remaining nuts.
- Bake 28 to 30 minutes until just set. Cool before cutting.
Notes
Toast the hazelnuts first for a deeper, nuttier flavor.
