Pre-heat oven to 350 degrees.
Combine icing ingredients until smooth and set aside in the freezer.
In a food processor, mix black beans, applesauce, honey, vanilla extract, Truvia and almond milk until smooth. Add coconut flour, cocoa powder, protein powder and baking powder and blend until smooth. Mix in egg white and chocolate chips by hand.
Spray 2 small ramekins with non-stick cooking spray (I like the coconut oil kind). Divide batter evenly between ramekins and top with extra chocolate chips if desired.
Bake at 350 degrees for 20-22 minutes or until a toothpick inserted in the center comes out mostly clean. Allow to cool for several minutes before icing and serving.
