The only thing I suggest is that you use PLAIN yogurt if you are going to add sugar to it. I used a vanilla yogurt and whoa - it was sweet.
PB Chocolate Chip Cookie Dough Yogurt
1 Plain Greek Yogurt
1 Tbsp. Peanut Butter
1 Tbsp. Sweetner
1 Tbsp. Mini Chocolate Chips
1/4 tsp. Vanilla
DIRECTIONS: Mix all ingredients. Eat!
*Note: You may substitute vanilla yogurt - however, omit the sugar and vanilla.
