I thought this was a very good recipe. I couldn't tell there was no sugar in the muffins. When I made this recipe I used the 4 tablespoons of the protein powder. I got this recipe from Obesity Help. It was posted by thekingskid.
Grease muffin tins with Pam spray. Combine flour, Splenda, baking powder, baking soda, salt & cinnamon and mix together. In a bowl, beat egg whites with a wisk or fork. Stir in mashed banana, applesauce, nuts and milk. Add flour mixture and mix together. Spoon into muffin tins.
Bake for 20-25 minutes. Stick a toothpick in the center of muffin to be sure cooked thru. Cool in pan for 5 minutes then remove and cool on a wire rack.
