Step 2
In a large bowl, mix together the oats, protein powder, cinnamon, and baking powder.

If your bananas aren't very ripe you may need to microwave them for 30 seconds to a minute to soften them up. Peel the bananas, place them into a bowl with the butter and microwave them until they are mashable. If your bananas are already ripe enough, they should be mashable as is.
Step 4
Add in the egg whites, milk, syrup, 1 tbsp of melted butter, and mashed bananas. Stir to combine.
Step 5
Spray a 13"x9" pan with oil and add the oat mixture.
Step 6
Bake for 35-40 minutes.
Step 7
In a small bowl, mix the powdered sugar, pinch of salt, vanilla, and 1 tsp of milk. Stir vigorously until a glaze has formed. If you need a few extra drops of milk to help things move, add it.
Step 8
Place the icing into a piping bag and drizzle over the top once the oatmeal has come out of the oven.
