Stir together yogurt, oats, milk, chia seeds and vanilla in a large bowl. Scoop 1/4 of the mixture into the bottoms of two 16 ounce mason jars (or other container) with lids.
Top each with 1/4 of the banana and blueberries, and 2 tablespoons Honey Nut Cheerios™. Repeat layers, place lids on top and store in the refrigerator. Parfaits will stay good for 2-3 days. Enjoy!
