All Natural Peanut Butter Yogurt

I will go ahead and say this recipe is not for everyone.   I personally love it and think it is a great snack, but have found some people are not a fan... Mr. Hungry being the biggest non-fan.   I found this recipe a long time ago in a dieting book called The Formula that my parents were using.  While I have never been on the diet it recommends, I have made this yogurt for years.  It is a part of the 40-30-30 diet (or zone diet), which promotes eating meals and snacks that have 40% carbohydrates, 30% protein and 30% fat.  I love that the yogurt uses all natural ingredients and because of the portions, seems to really fill me up.  These are not all ingredients you would have on hand, but I use protein powder for certain smoothies as well so have found it to be a good investment.  It is more expensive than most products I buy, but one can will last a very long time.   
All Natural Peanut Butter Yogurt
4 Servings
Recipe Notes
Using all natural fructose is a healthier alternative to table sugar.  Bob's Red Mill makes a granulated fructose that can be found in alot of grocery store.   I buy protein powder at Whole Foods, but can now be found in most grocery stores in the health food aisle as well.  The original recipe is for one serving.  I have adapted this to make four servings so I can make once, and eat throughout the week.  
32 oz. tub of nonfat plain yogurt (4 cups)
4 tablespoon all natural peanut butter, room temperature
8 teaspoons granulated fructose
2 tablespoons pure whey protein powder
1.  Combine all ingredients in mixing bowl or blender.
2.  Whisk or blend until smooth and creamy.
3.  Divide into four containers and refrigerate until ready to eat.
