These cozy banana oatmeal muffins are easy to whip up in a blender! Add streusel for a sweet crunch, or go healthy with a sprinkle of oats.



For the batter

  • 3 large ripe bananas (broken into pieces)
  • 1/2 cup maple syrup
  • 1/4 cup neutral oil
  • 1 egg (or flax egg for vegan)
  • 1 tablespoon vanilla extract (or 1/2 tablespoon almond extract)
  • 1 1/2 cups rolled oats
  • 3/4 cup all-purpose flour (for gluten free, go to Blender Muffins)
  • 1 teaspoon cinnamon
  • 1 teaspoon allspice
  • 2 teaspoons baking powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon kosher salt

For the streusel topping (or use 3 tablespoons roughly chopped oats & 2 tablespoons turbinado or brown sugar)

  • 2 tablespoons all-purpose flour
  • 2 tablespoons rolled oats
  • 3 tablespoons turbinado sugar or dark brown sugar
  • 2 tablespoons salted butter (or coconut oil for vegan)
  • 1/2 teaspoon cinnamon


  1. Preheat the oven to 350 degrees Fahrenheit. 
  2. Mix the streusel topping ingredients, with the butter cut into small pieces, in a small bowl with a fork until crumbly. Or, mix the optional chopped oats and brown sugar. Set aside.
  3. Combine all the batter ingredients in blender and blend until a smooth batter forms (don’t over blend). Pour into 10 muffin cups. Crumble a bit of the streusel topping onto each muffin.
  4. Bake 25 to 28 minutes until a toothpick comes out mostly clean with a few clinging crumbs. Allow to cool in the pan for 5 minutes, then remove the muffins and place them on a cooling rack. Cool 1 hour until room temperature. Store up to 4 days in a sealed container with a paper towel inside (to keep the topping crumbly) or frozen up to 3 months. You can also refrigerate the muffins, but they can become dry and the topping becomes soft.
