Throw all ingredients into a food processor or blender and blend until smooth.
Add to a loaf pan coated with cooking spray. Bake about 25-30 minutes or until knife comes out clean. Transfer to a large plate or cooling rack and cool completely.
To make the frosting, mix together the Greek yogurt and protein powder. Spread evenly over the top of the cake. I cut my cake into four pieces and layered them, but that doubles the serving size. Do what you like!
