Overnight Breakfast Bars

The original recipe called for 1 tbsp baking soda which seemed wrong - I changed it to 1 tsp. Flax meal is available at major supermarkets and in health food stores. Substitute 1 cup shredded carrots for 1 apple, if desired. Substitute plain yogurt for the buttermilk, if desired. Recipe Source: Relish Mag
