Cooking With Dr. Sara: Protein Peanut Butter Fluff

Slow-absorbing casein protein is great before bed. This recipe utilizes the muscle-building properties of casein in a sweet tooth-friendly snack!

I'm not sure desserts get any better than delicacies with peanut butter and chocolate. Actually, I'm sure they don't. This recipe includes both of those mouth-watering ingredients, but it's even better because it also has that extra special macronutrient: protein. If you can't have your usual cookies and milk before bed, this is the next best thing.
