In a large bowl, mash the bananas then add in the applesauce, milk and coconut oil and mix well
Mix in the oat flour, baking powder and cinnamon until smooth and well combined
Evenly distribute cake batter to pans and bake in oven for 15 minutes or until ready (I stick a toothpick in)
Allow the cakes to cool completely then gently remove one cake from pan and add to plate and spread frosting on top then add additional cake and repeat for the remaining cakes
Frost the cake in its entirety then add sprinkles if desired
Notes
*This cake will stay good for 3-4 days (I recommend keeping in fridge)
