These blender muffins are so easy to whiz up and come out fluffy with no flour! They’re a fantastic make-ahead healthy breakfast or snack. For other blender muffin flavors, see Healthy Blueberry Muffins and Apple Zucchini Muffins.
Place all ingredients in a blender, breaking the bananas into pieces as you add them. Blend everything on high for a minute or two until a smooth batter forms.
Place 9 to 10 muffin cups into a muffin tin and pour the batter divided evenly between the cups; the amount of muffins will depend on the size of the bananas and type of oats. Sprinkle the tops with extra oats and gently press them down.
Bake for about 25 to 35 minutes until a toothpick comes out clean. Remove from the muffin tin and allow them to cool a few minutes before serving. Store refrigerated or frozen.
