Coffee and banana seem like an unlikely combination, but the flavors complement each other incredibly well. Simply leave out the coffee if youâ€™re not a fan, but it adds a nice additional flavor that isnâ€™t too strong. These muffins are simultaneously fluffy and also hearty due to the oats and make a great portable breakfast. With 265 calories for a big muffin (or 198 for a smaller one), theyâ€™re not incredibly unhealthy either. Everyone wins!
