Ingredients Equipment Method Notes

Ingredients
  

  • 1 ½ cups all-purpose flour
  • 1 cup rolled oats
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ cup brown sugar
  • 2 ripe bananas optional, mashed
  • ½ cup melted butter or oil or dairy-free alternative
  • 1 cup leftover oatmeal can be made from cooked oats
  • 1 teaspoon vanilla extract
  • ½ cup dried fruit or nuts optional
  • ½ teaspoon cinnamon

Equipment

  • Oven
  • Muffin tin
  • Mixing bowls
  • Whisk
  • Muffin scoop
  • Spatula

Method
 

  1. Preheat your oven to 180°C (350°F) and line a muffin tin with paper liners or lightly grease it.
  2. In a large mixing bowl, whisk together the flour, oats, baking powder, baking soda, cinnamon, and brown sugar until well combined.
  3. In a separate bowl, mash the ripe bananas until smooth, then whisk in the melted butter or oil, leftover oatmeal, and vanilla extract. The mixture should be slightly thick and fragrant.
  4. Pour the wet ingredients into the dry mixture and gently fold together with a spatula until just combined. Be careful not to overmix; a few lumps are okay.
  5. If using, fold in dried fruit or nuts for added texture and sweetness.
  6. Using a muffin scoop, portion the batter evenly into the prepared muffin tin, filling each about ¾ full.
  7. Bake in the preheated oven for about 20–25 minutes, or until the muffins are golden brown and a toothpick inserted into the center comes out clean.
  8. Remove the muffins from the oven and let them rest in the tin for 5 minutes to set before transferring to a wire rack to cool slightly.
  9. Serve warm or at room temperature, perhaps with a drizzle of honey or a sprinkle of cinnamon for extra flavor.

Notes

For a moister muffin, avoid overmixing the batter. Feel free to customize with your favorite add-ins like chocolate chips or shredded coconut.
