  • 1 and 1/2 cups (189g) all-purpose, white flour
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 3/4 teaspoon cinnamon
  • 1/2 teaspoon nutmeg
  • 2-3 (260g) very ripe bananas, mashed (1 packed full cup)
  • 1/2 cup (100g) white sugar
  • 1/4 cup (42g) light brown sugar, packed
  • 1 large egg, lightly beaten
  • 1/3 cup butter, melted
  • 1 teaspoon vanilla extract

Crumb Topping

  • 2 tablepoons light brown sugar, packed
  • 2 tablespoons white sugar
  • 1/4 cup + 2 tablespoons (45g) all-purpose white flour
  • 1/2 teaspoon cinnamon
  • 3 tablespoons butter, melted


  1. Preheat oven to 375 degrees F. Lightly grease and flour 10 cavities in a muffin tin. Fill the other two muffin cavities halfway with water (ensures even baking)

  2. In a large bowl, mix together the flour, baking soda, baking powder, salt, cinnamon, and nutmeg. In another bowl, beat together bananas, white sugar, brown sugar, egg, melted butter, and vanilla extract. Stir the banana mixture into the flour mixture until JUST combined. Do not overmix (will result in denser muffins). Spoon batter into prepared muffin cups.

  3. In a small bowl, make the crumb topping: combine the brown sugar, white sugar, flour, and cinnamon. Whisk until combined and then add in the melted butter and stir until crumbs form. Sprinkle this mixture evenly onto the 10 muffins.

  4. Bake in preheated oven for 18 to 20 minutes, until a toothpick inserted into center of a muffin comes out clean.
  5. Remove and allow to cool on a cooling rack. Muffins are best within 3 days.
