If starting with dry adzuki beans, simmer the beans in enough water to cover the beans until they are tender and fall apart easily. Drain the beans well.
Pre-heat the oven to 350 degrees. Blend all ingredients, except eggs, until smooth in a food processor. Then add eggs and pulse until combined.
Line a small pan (for example, 8 inch square pan) with parchment paper and grease with coconut oil. Bake for about 25 minutes until the middle is firm and springs back.
Allow the brownies to cool before slicing into squares.
Recipe Notes
If using black beans, use a 16-ounce can of black beans.
