Make these soft, moist banana oatmeal muffins using one bowl for easy cleanup. They use ripe bananas for natural sweetness and are perfect for quick breakfasts or kid-friendly snacks.

Ingredients

Scale
  • 3 very ripe large bananas, mashed
  • 1/4 cup melted coconut oil or vegetable oil
  • 1/4 cup maple syrup or honey (optional, adjust based on banana sweetness)
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1 1/2 cups rolled oats (not instant)
  • 1/2 cup milk (dairy or non-dairy)
  • 1/2 cup mix-ins like chocolate chips or chopped walnuts (optional)

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 bowl, mash the ripe bananas until mostly smooth.
  3. Add the melted oil, maple syrup (if using), egg, and vanilla extract to the mashed bananas. Whisk until combined.
  4. Add the baking soda, cinnamon, and salt to the wet ingredients. Mix briefly.
  5. Stir in the rolled oats until just incorporated.
  6. Pour in the milk and mix until the batter is uniform. Do not overmix.
  7. Fold in any optional mix-ins like chocolate chips or nuts.
  8. Divide the batter evenly among the 12 muffin cups, filling each about two-thirds full.
  9. Bake for 18 to 22 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
  10. Let the muffins cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • For freezer-friendly muffins, allow them to cool completely, then store them in an airtight container or freezer bag for up to three months. Thaw overnight on the counter or microwave briefly.
  • If you skip the maple syrup, the muffins will rely solely on banana sweetness, making them a guilt-free treat.
  • These are excellent for meal prep breakfast ideas; they hold up well for grab-and-go meals.
