0 Preheat the oven to 350 degrees F. Lightly grease a silicone donut pan.
1 Blend the bananas, almond butter, coconut oil, vanilla, and eggs together until smooth. Blend in the almond flour, vanilla protein powder, baking soda, and baking powder. Stir in the blueberries.
2 Pour the batter into the prepared pan and bake for 22 minutes, or until a toothpick comes out clean.
3 Cool completely before removing from the pan. Dip the donuts in icing (melted coconut butter or cream cheese with honey mixed in), if desired.
