Instructions
 

Donuts

  • Prepare Pan and Oven:

    Grease a nonstick donut pan lightly with butter or spray; set aside. Heat oven to 350°F (175°C).

  • Mix Dry Ingredients:

    In a bowl, combine flour, cinnamon, baking powder, baking soda, and salt with a whisk.

  • Whisk Wet Ingredients:

    In another bowl, whisk buttermilk, melted butter, mashed banana, granulated sugar, ¼ cup brown sugar, sour cream, oil, and 2 tsp vanilla.

  • Combine Wet and Dry:

    Fold wet mixture into dry mixture until no streaks remain.

  • Fill Donut Pan:

    Transfer batter to a piping bag and fill the donut pan.

  • Bake Donuts:

    Place pan on the center rack and bake for 11-12 minutes, until tops bounce back when pressed.

  • Cool and Remove Donuts:

    Cool the pan on a wire rack, then invert and carefully remove donuts.

Glaze

  • Make Brown Sugar Glaze:

    For the glaze: In a saucepan, heat 4 tbsp butter and ½ cup brown sugar until smooth. Stir in milk and bring to a simmer. Take off heat, whisk in powdered sugar and 2 tsp vanilla until smooth. Pour into a bowl and let rest for 10-12 minutes. Glaze will be thin but thickens as it cools.

Caramelized Bananas

  • Caramelize Bananas:

    For caramelized bananas: In a saucepan over medium heat, melt ½ tbsp butter. Sprinkle 2 tbsp brown sugar and ¼ tsp cinnamon over the butter, then add banana slices. After 2 minutes, flip gently and cook for 1 more minute.

  • Glaze Donuts:

    Dip donut tops into the glaze. If glaze drips off quickly, let it cool longer. If too thick, warm in a microwave in 10-15 second bursts until desired consistency.

  • Top with Bananas:

    Place caramelized banana slices in the center of each donut and serve.
