Sometimes my son needs a quick fix for protein. I love Zoku for good food masquerading as TREATS! I'll be delving into fancy Zoku pop ideas and recipes soon this summer, but today, I just grabbed our chocolate protein powder (sweetened only with Stevia), PB & some milk. Blended it up and poured it in the Zoku. One and done. Yummy & nutritious. Strawberries may have been even yummier.
