Servings 12 muffins

Equipment

  • Measuring cups, spoons
  • 1 Large mixing bowl
  • Hand mixer with beaters
  • 1 small mixing bowl
  • rubber spatula
  • spoon
  • Large spoon/cookie scoop
  • Muffin Tin
  • Silicone or paper muffin cups
  • Cooking spray

Ingredients

  • ½ cup granulated sugar
  • ½ cup butter softened
  • 1 ½ whole ripe bananas
  • 1 egg
  • ½ cup milk
  • 1 teaspoon lemon juice
  • 1 cup + 2 teaspoons all purpose flour divided
  • ½ cup whole wheat flour
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • 1 ½ cup blueberries fresh or frozen
  • ¾ cup oats
  • 2-3 Tablespoons turbinado sugar

Instructions

  • Preheat oven to 375 degrees F. Line muffin pan with silicone muffin cups and spray with cooking spray.
  • Add ½ cup granulated sugar, ½ cup softened butter to medium mixing bowl. Beat with hand mixer until mixture is smooth and fluffy.
  • Add 1 ½ ripe bananas, 1 egg, ½ cup milk, and 1 teaspoon lemon juice to batter. Beat until smooth.
  • Add 1 cup all purpose flour, ½ cup whole wheat flour, 2 teaspoons baking powder, ½ teaspoon salt. Beat on low and until just barely incorporated.
  • If using frozen blueberries, sprinkle 2 teaspoons flour over 1 ½ cup blueberries, and mix until blueberries are coated. This will prevent some bleeding from the blueberries and keep them from all sinking in the mixture.
  • Add blueberries and ¾ cup oats to mixture. Carefully fold them into batter with rubber spatula.
  • Using a large spoon or cookie scoop, divide batter evenly between 12 muffin cups. Sprinkle turbinado sugar over each muffin (about 2-3 Tablespoons worth).
  • Bake for 15-18 minutes, or until a toothpick comes out clean.
  • Store in airtight container for a couple days, or in freezer bag for months.

Notes

  • Use frozen or fresh bananas, but make sure they're brown and very ripe. 
  • You can use any combination of whole wheat flour and all purpose flour, but 100% whole wheat flour will make your muffins more dense than fluffy.
  • You can use either fresh or frozen blueberries in your banana blueberry oatmeal muffins. If using frozen blueberries, toss them in flour before adding to batter.
  • Optional add-ins: chocolate chips, chopped nuts, mixed berries.
