Well for frosting there is the traditional
1 Cup Greek yogurt (I used Stonyfield Farms)
A good splash of vanilla extract (I used 1 t)
1/2 C powered sugar, sifted
or
1 cup greek yogurt
1 scoop protein powder
or
1 cup greek yogourt
1/2 cup fruit preserves
Or just get you favorite yogourt and dunk them in like a dip.
