Preheat oven to 350 degrees F. Line your muffin pan with silicone muffin cups or brush the muffin tins a little oil.
Combine flour, oats, baking powder, salt, cinnamon and orange rind in a large bowl.
In a medium bowl, combine mashed bananas, milk, oil, applesauce and egg with a wire whisk.
Add the banana mixture to the flour mixture and stir until combined. Fold in cranberries.
Fill each muffin cup to the top. About 2 tablespoon in each cup.
Bake for 25 minutes or until inserted toothpick comes out clean.
Let muffins cool out of the muffin tins completely. Store in an air-tight container.
