Pour half of your yogurt on top of your graham cracker in the mason jar. It ends up being just a little more than 1/4 cup of yogurt in each. Repeat for all 6 mason jars.
NOTE: We've chosen to add Mixed Berry Yogurt to our mason jars, but you could definitely choose another flavor that best fits your family. And if you don't have blueberries, any delicious chopped up fruit will work great too.
