Ingredients

  • 2 cups all-purpose flour
  • 1 cup granulated sugar
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon ground cinnamon
  • 2 eggs
  • 1 cup sour cream
  • 1/4 cup butter melted
  • 2 bananas ripe, mashed; about 1 cup
  • 1/2 cup pecans or walnuts chopped, optional
  • 1/2 cup brown sugar
  • 3 tablespoons all-purpose flour
  • 1/4 teaspoon ground cinnamon
  • 4 tablespoons butter softened

Instructions

  1. Preheat oven to 375 degrees Fahrenheit. Line a muffin pan with cupcake liners or spray with non-stick cooking spray.
  2. In a large bowl, combine 2 cups all-purpose flour, 1 cup granulated sugar, 1 teaspoon baking powder, 1/2 teaspoon salt, 1/2 teaspoon baking soda, and 1/4 teaspoon ground cinnamon; set aside.
  3. In a medium bowl, add 2 eggs, 1 cup sour cream, 1/4 cup melted butter, and 2 ripe mashed bananas; beat with a hand mixer until smooth.
  4. Stir the flour mixture into the wet ingredients until just moistened. Fold in 1/2 cup chopped pecans or walnuts if using. Fill the muffin cups 2/3 of the way full.
  5. In a small bowl, combine 1/2 cup brown sugar, 3 tablespoons all-purpose flour, and 1/4 teaspoon ground cinnamon. Cut in 4 tablespoons softened butter with the back of a fork until the mixture is crumbly.
  6. Sprinkle the streusel evenly over the muffin batter and bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean and the tops are lightly golden.

Notes

Use very ripe bananas (about 1 cup mashed) for the best banana flavor. Do not overmix the batter—stir only until the ingredients are combined to keep the muffins tender. The streusel can be made ahead and the muffins freeze well for easy reheating later.
