Ingredients
Preparation
Step 1
Preheat oven to 350° F. and butter and flour a 9-inch square baking pan, knocking out excess flour.
Step 2
Toast and skin hazelnuts (procedure this page). In a food processor pulse hazelnuts until coarsely ground (bits should be about 1/8 inch).
Step 3
Chop chocolates into small pieces and in a double boiler or a metal bowl set over a saucepan of barely simmering water melt chocolates with butter and Nutella, stirring occasionally until smooth. Remove top of double boiler or bowl from heat.
Step 4
While chocolates are melting, into a bowl sift together flour, baking powder, and a pinch salt. Whisk sugar into chocolate mixture until combined well. Add eggs, whisking until mixture is glossy and smooth. Stir in flour mixture and hazelnuts until just combined.
Step 5
Pour batter into baking pan and bake in middle of oven 35 to 40 minutes, or until a tester comes out with moist crumbs adhering to it. Cool brownies completely in pan on a rack and cut into 16 squares. Brownies keep, layered between sheets of wax paper in an airtight container at cool room temperature, 5 days.
