Made with almonds and hazelnuts and covered with dark chocolate frosting, these cupcakes are worth serving on their own. Add a sleek touch by topping the cupcakes with caramel-dipped hazelnut spikes.
- 1/2 cup whole unblanched almonds, toasted
- 1/2 cup hazelnuts, toasted and skinned
- 3/4 cup all-purpose flour
- 3/4 cup cake flour (not self-rising), sifted
- 1 1/2 teaspoons baking powder
- 1/4 teaspoon salt
- 1/2 cup (1 stick) unsalted butter, room temperature
- 1/4 cup granulated sugar
- 1/2 cup firmly packed dark-brown sugar
- 3/4 cup milk
- 4 large egg whites
- Dark Chocolate Frosting
- Caramel-Dipped Hazelnuts
Preheat oven to 350 degrees. Line standard muffin tins with paper liners. In a food processor, pulse together almonds and hazelnuts until finely ground (do not overprocess, or the nuts will turn into a paste). Into a mixing bowl, sift together both flours, baking powder, and salt. Whisk in the ground nuts.
With an electric mixer on medium-high speed, cream butter and both sugars until smooth. Beat in vanilla. Reduce speed to low. Add flour mixture in three batches, alternating with two additions of milk, and beating well after each.
In another mixing bowl, with electric mixer on medium speed, whisk the egg whites until soft peaks form. In two additions, gently fold the egg whites into the batter.
Divide batter evenly among lined cups, filling each three-quarters full. Bake, rotating tins halfway through, until a cake tester inserted in centers comes out clean, about 25 minutes. Transfer tins to wire racks to cool completely before removing cupcakes. Cupcakes can be stored up to 3 days at room temperature, or frozen up to 2 months, in airtight containers.
Using an offset spatula, spread frosting over each cupcake. Cupcakes can be refrigerated up to 3 days in airtight containers; bring to room temperature and top with caramel-dipped hazelnuts just before serving.
