Preheat oven to 350 degrees
Place large paper liners in muffin pan.
Add black beans, 4 eggs, vanilla extract, sugar and coconut oil to the blend. Blend on high for 1-2 minutes until smooth.
In a small bowl gently mix cocoa powder, baking powder and baking soda.
Add dry ingredients to the blender.
Blend on high for another 1-2 minutes.
Pour batter into prepared pan.
Bake for about 20-25 minutes until cupcakes are completely cooked. I find 22 minutes perfect.
Optional: Allow to cool completely before icing.
If using a mini muffin pan reduce baking time to 16-18 minutes.
