Instructions
Preparation Steps
Heat oven to 350°F. Line an 8-inch square pan with parchment, leaving overhang. Lightly grease the parchment.
Whisk melted butter, 1 1/4 cups chocolate-hazelnut spread, sugar, and vanilla in a large bowl until smooth.
Beat in eggs and the extra yolk, one at a time, until the batter looks thick and glossy.
In a separate bowl, whisk flour, cocoa, salt, and baking powder to combine.
Fold the dry mixture into the wet just until no dry streaks remain. Stir in chocolate chips if using.
Spread batter evenly in the pan. Dollop the remaining 2 tbsp chocolate-hazelnut spread on top and gently swirl.
Bake 22–28 minutes, until edges are set and a toothpick has moist crumbs, not wet batter.
Cool completely in the pan. Lift out, cut into squares, and finish with a pinch of flaky salt if desired.
