Banana Bread Donuts with Nutella Glaze

Preheat oven to 350 ºF. Spray your donut pan with nonstick spray. You want to do this after baking every batch. In a bowl, whisk together flours, baking powder and salt. In a large bowl, whisk together butter and sugar until combined. Add dry ingredients and eggs, mixing until batter is just combined. Whisk in bananas and vanilla paste, then stir in buttermilk until batter is smooth. Use a spoon and add batter to the donut pan until each mold is about 3/4 full. Bake donuts for 13 –15 minutes, until they are set and slightly golden. Remove and let cool. Once they are cool, dip each donut in the glaze and cover in sprinkles. Serve immediately.
