Iced Lemon Protein Loaf

Nothing says "spring" like a refreshingly sweet slice of this Iced Lemon Protein Loaf! The lemon cake is incredibly moist and topped with a sweet but zesty icing. It's also gluten-free and low in fat, with 10 grams of protein per 120-calorie slice.


NOTES: We used gluten free flour but you can also use all-purpose flour, cake flour, fine oat flour, cassava flour, or sorghum flour.

Preheat your oven to 350 degrees F. 

Whisk together dry ingredients (through salt) in a medium mixing bowl.
