Make soft, moist, and naturally sweet banana oatmeal muffins using only one bowl for simple preparation and cleanup. These are perfect for quick breakfasts or healthy snacks.

Ingredients

Scale
  • 3 very ripe large bananas, mashed
  • 1/4 cup melted unsalted butter or coconut oil
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 cup packed light brown sugar (optional, reduce or omit for less sweetness)
  • 1 1/2 cups rolled oats (old-fashioned or quick oats)
  • 1 teaspoon baking soda
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup milk (dairy or non-dairy)
  • Optional: 1/2 cup chocolate chips or chopped nuts

Instructions

  1. Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease well.
  2. In a large mixing bowl, mash the ripe bananas until mostly smooth.
  3. Add the melted butter (or oil), egg, and vanilla extract to the mashed bananas. Whisk until combined.
  4. Stir in the brown sugar, if using.
  5. Add the rolled oats, baking soda, cinnamon, and salt to the wet ingredients. Mix gently until just combined. Do not overmix.
  6. Pour in the milk and mix briefly until the batter comes together. Fold in any optional add-ins now.
  7. Divide the batter evenly among the 12 prepared muffin cups. The batter will be thick.
  8. Bake for 18 to 22 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
  9. Let the muffins cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • For a truly ‘no added sugar’ version, omit the brown sugar entirely; the ripe bananas provide sufficient natural sweetness.
  • These muffins freeze well. Cool completely, then store in an airtight, freezer-safe bag for up to 3 months. Thaw overnight on the counter or reheat briefly.
  • To achieve a bakery-style topping, sprinkle a small amount of coarse sugar over the tops of the batter before baking.
  • If you prefer a finer texture, pulse the rolled oats in a food processor briefly to create a coarse oat flour before mixing.
