A dollop of chocolate-hazelnut spread lends unexpected decadence to a hazelnut blondie.
- 1/2 stick (4 tablespoons) unsalted butter, plus more for pan
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- 1 teaspoon salt
- 1 3/4 cups packed light-brown sugar
- 2 large eggs
- 1 teaspoon pure vanilla extract
- 1/3 cup hazelnuts, toasted, skins rubbed off with a kitchen towel, and chopped
- 1 heaping tablespoon chocolate-hazelnut spread, such as Nutella, plus more for serving
Preheat oven to 350 degrees. Butter an 8-by-11-inch baking pan. Line with parchment paper. Butter parchment.
Whisk flour, baking powder, and salt.
Melt butter. Beat butter and sugar until combined. Beat in eggs and vanilla. Add flour mixture, and stir until combined. Stir in hazelnuts and Nutella.
Press dough into pan. Bake until a toothpick comes out with a few moist crumbs, about 25 minutes. Let cool 15 minutes. Cut into squares. Serve with additional Nutella.
