Create ultra-moist banana oatmeal muffins using a simple one-bowl method. These hearty muffins use ripe bananas for natural sweetness, making them perfect for quick grab-and-go breakfasts or freezer-friendly meal prep.

Ingredients

Scale
  • 1 3/4 cups all-purpose flour
  • 1 cup rolled oats
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1/2 cup unsalted butter, melted
  • 1/2 cup packed light brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup mashed ripe bananas (about 3 medium)
  • 1/4 cup milk (any kind)
  • Optional: 1/2 cup chocolate chips or chopped walnuts

Instructions

  1. Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease it well.
  2. In a large bowl, whisk together the flour, rolled oats, baking soda, salt, and cinnamon. This is your dry mixture.
  3. In a separate medium bowl, whisk the melted butter and brown sugar until combined.
  4. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract and the mashed bananas until smooth.
  5. Pour the wet ingredients into the dry ingredients. Mix with a spatula until just combined. Do not overmix; a few streaks of flour are acceptable.
  6. If using, gently fold in the chocolate chips or walnuts.
  7. Divide the batter evenly among the 12 muffin cups, filling each about two-thirds full.
  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 pan for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • Use bananas that are heavily spotted or almost black for the best natural sweetness and moisture.
  • For freezer-friendly muffins, cool them completely, then store them in an airtight, freezer-safe bag for up to three months. Thaw overnight on the counter or microwave briefly.
  • To achieve bakery-style muffins, fill the cups slightly higher and bake at 400°F (200°C) for the first 5 minutes, then reduce the temperature to 375°F (190°C) for the remaining bake time.
