1 large egg

5 tablespoons all=purpose flour

1/2 cup chopped hazelnuts

Directions

Heat the oven to 350 degrees. Line a 12-cup mini muffin pan with paper or foil liners.

Put the Nutella and egg in a medium bowl and whisk until smooth and well blended. Add the flour and whisk until blended.

Spoon the batter into the prepared muffin tins (about 3/4 full) and sprinkle with the chopped hazelnuts.

Bake until a pick comes out with wet, gooey crumbs, 11 to 12 minutes. Set on a rack to cool completely. Serve immediately or cover and store at room temperature for up to 3 days.
