Ingredients

  • 2¼ cups all-purpose flour
  • 2 tsp baking powder
  • ½ tsp salt
  • 3 ripe bananas
  • ¼ cup butter (at room temperature)
  • ½ cup sugar
  • ¼ cup brown sugar
  • 2 eggs
  • 2 tsp vanilla extract
  • ½ cup sour cream
  • ½ cup instant oats
  • ½ cup walnuts, finely chopped
  • Optional: extra oats for topping

Instructions

  1. Preheat oven to 375°F (190°C), no fan.
  2. In one bowl, whisk together flour, baking powder, and salt.
  3. In a separate bowl, mash the bananas into a puree.
  4. In a mixer, cream butter with sugar and brown sugar. Add eggs one at a time, then mix in sour cream and vanilla extract.
  5. Add the dry flour mixture to the wet ingredients and stir gently with a spoon. Do not overmix.
  6. Fold in mashed bananas, oats, and chopped walnuts.
  7. Line a muffin tray with paper cups and fill each with the batter. Sprinkle tops with additional oats if desired.
  8. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
  9. If tops are not golden enough, broil for 2–3 minutes at the end.
  10. Remove muffins from the oven and let cool on a wire rack.

Notes

  • Use overripe bananas for best flavor and moisture.
  • Do not overmix the batter to keep the muffins soft and fluffy.
  • You can substitute yogurt for sour cream if desired.
