Nutella Brownies (Gourmet Magazine)
Gianduia Nutella Brownies
1-1/4 C hazelnuts (about 6-1/4 oz)
4 oz bittersweet chocolate (not unsweetened)
3 oz milk chocolate
1 stick (1/2 C) unsalted butter, plus more for the pan
¼ C Nutella
½ C all-purpose flour, plus more for the pan
½ t baking powder
½ C granulated sugar
2 large eggs
Preheat oven to 350 F. Butter a 9-inch square baking pan and line it with two crisscrossed sheets of aluminum foil, allowing the excess to hang out over the edges. Butter the foil and dust the pan with flour, tapping out any excess flour.
Toast the hazelnuts on a rimmed baking sheet for 10-15 minutes, or until the nuts are lightly colored and the skins are blistered. Wrap the nuts in a kitchen towel and steam for 1 minute; then rub them in the towel to remove the loose skins. Cool completely.
In a food processor, pulse the cooled hazelnuts until coarsely ground (the bits should be about 1/8” in diameter).
Chop the two different types of chocolate into small pieces. In a double boiler or a metal bowl set over a saucepan of barely simmering water, melt the chocolate with the butter and Nutella, stirring occasionally, until smooth. Remove from the heat.
While the chocolate is melting, sift together the flour, baking powder, and salt in a bowl.
Whisk the sugar into the chocolate mixture until well combined. Add the eggs, whisking until the mixture is glossy and smooth. Stir in the flour mixture and the hazelnuts until just combined.
Scrape the batter into the prepared pan and bake for 35-40 minutes, or until a tester comes out with moist crumbs adhering to it. Cool the brownies completely in the pan on a rack and cut into 16 squares. The brownies will keep, layered between sheets of wax paper in an airtight container at cool room temperature, for up to 5 days.
