Nutella and Banana Filled Aebleskiver

from Sticky, Gooey, Creamy, Chewy

4 eggs, separated
2 cups buttermilk
1 teaspoon vanilla
1/4 cup melted unsalted butter
2 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon fine sea salt
2 tablespoons sugar
1/2 cup Nutella
1 banana, sliced into quarters lengthwise and then into small chunks
1 tablespoon melted butter for pan

Beat egg whites until stiff but not dry, and set aside.

In a small bowl, whisk together the egg yolks, buttermilk, vanilla and butter. In another bowl, whisk together the flour, baking powder, salt and sugar.  Combine the yolk mixture into the flour mixture and whisk until well blended.  The batter will be a little lumpy.  Using a rubber spatula, gently fold in the egg whites in two additions.

Heat an aebleskiver pan over medium heat and brush each well with melted butter. Pour about 1 tablespoon of the batter into each well. Add 1/2 teaspoon of Nutella and 1-2 chunks of banana to each well. Then top off each well with enough batter to fill.  

Cook about 3 minutes or until golden brown on the bottom and bubbly around the edges, Quickly turn each aebelskiver over, using a long wooden skewer or toothpick, trying not to puncture the balls.  Continue cooking until golden on the bottom, about 2 minutes more.

Transfer to a plate and repeat the process with the remaining batter.

Dust with powdered sugar or drizzle with chocolate sauce and serve immediately.

Makes about 35.
