Can you tell I don’t like washing dishes? The fewer the better, without compromising taste of course. Plump, purple blueberries burst inside of these little guys, lending a tangy sweetness. Ripe, mashed banana and nondairy yogurt or applesauce are easy substitutes for oil. Sprinkle brown sugar and cinnamon on top before baking for a sweet, crumbly muffin top. I bet you can’t eat just one.
