The black bean brownie is an American variation that uses bean puree as the base of the batter. This gluten-free recipe is based on a simple idea: replacing flour with a natural ingredient rich in protein. The result is a dense, moist, and structured cake, and the cocoa gives it the sweetness that children crave. It's a dessert designed for simplicity, to be prepared with everyday ingredients. The mixture is made in a blender or food processor, to obtain a smooth batter effortlessly. This gives the characteristic texture of a brownie without using traditional flour. As with the traditional brownie, you can add nuts. This cake is delicious, but be careful not to overbake it or it will become dry.
Preheat the oven to 180°C.
Let cool before cutting into squares.
