I haven't tried this yet but I just found the recipe online and thought it looked very interesting.

Garbanzo Bean Chocolate Cake

This cake puts the sweetness back into your gluten-free diet.

Ingredients:

1 1/2 cups semisweet chocolate chips (try gluten-free)


1 can of garbanzo beans, rinsed and drained


4 eggs


3/4 cup white sugar


1/2 teaspoon baking powder


1 tablespoon confectioners' sugar for dusting

Preheat oven to 350°F

Grease and flour one 9-inch round cake pan. Melt the chocolate chips
either in a double broiler or in a microwave, being sure to stir every
20 seconds to avoid burning.

Combine the beans and eggs in either a food processor or a blender, and
blend until smooth. Add the sugar and baking powder and blend. Finally,
add the melted chocolate, and once again, blend until smooth. Pour the
batter into the cake pan.

Bake for 40 minutes or until a fork or toothpick inserted into the
center of the cake comes out clean. Place cake (still in pan) on a wire
rack to cool for 10 to 15 minutes. Invert cake onto a serving plate.
Dust with confectioners' sugar just before serving. Berries are an
excellent option to add sweetness and color.
