Ingredients

Units Scale

Muffins:

  • 5 ripe bananas
  • 2 large eggs
  • 1/2 cup brown sugar, packed
  • 1/4 cup salted butter, melted
  • 1/4 cup neutral oil
  • 2 cups all-purpose flour, spooned and leveled
  • 1 1/2 teaspoons baking soda
  • 1 teaspoon cinnamon
  • 1/2 teaspoon salt

Cinnamon Swirl Filling:

  • 2 tablespoons brown sugar
  • 1 tablespoon melted butter
  • 1/2 teaspoon cinnamon

Streusel Topping:

  • 1/4 cup all-purpose flour
  • 1/4 cup brown sugar
  • 1 teaspoon cinnamon
  • 3 tablespoons cold butter, cubed

Instructions

  1. To make the muffin batter, add the ripe bananas, eggs, brown sugar, melted butter, and oil to a mixing bowl. Mix until the bananas are broken down into small pieces.
  2. Next, add the flour, cinnamon, salt, and baking soda. Begin to mix the wet and dry ingredients together until just combined.
  3. Preheat your oven to 350°F. Line a 12-cup muffin tin with parchment paper cups. Use cooking spray to grease the liners before filling the cups halfway with muffin batter.
  4. Mix the brown sugar cinnamon swirl filling and add a teaspoon to the centers of each of the muffin cups. Use a toothpick or knife to gently swirl the cinnamon sugar through the batter. Top the muffins with the remaining batter.
  5. In a small bowl, whisk together the flour, brown sugar, and ground cinnamon for the streusel topping. Use a pastry cutter or your fingers to rub the cold butter into the dry mixture until the butter is in small pieces. Top each of the muffins with the crumb topping before putting them in the oven.
  6. Bake the muffins at 350°F for 18-22 minutes or until a toothpick inserted in the center comes out clean or with a few crumbs. The edges of the muffins should be lightly golden brown. 

Notes

  • Note: Baking time may vary depending on your oven, how ripe your bananas are, and how full your muffin cups are. If your muffins don't seem fully baked by the 22-minute mark, bake for a few more minutes and check for doneness by pricking the center of a muffin with a toothpick or a small knife.
