Ingredients

Scale

Wet Ingredients

  • ⅔ cup packed light brown sugar
  • 2 tablespoons unsalted butter, melted
  • 1 large egg
  • 1 teaspoon vanilla extract
  • ⅔ cup mashed ripe banana (2 medium sized)
  • ½ cup sour cream
  • ⅔ cup whole milk

Dry Ingredients

  • 2 cups all purpose flour
  • 2 teaspoons baking powder
  • 1 teaspoon baking soda
  • ½ teaspoon table salt
  • 1 teaspoon cinnamon
  • ¾ cup graham cracker crumbs

Add-ins

  • 1 cup miniature chocolate chips, divided
  • 1 cup miniature marshmallow bits, divided

Instructions

  1. Preheat and Prepare Pan: Preheat the oven to 400°F. Line a muffin pan with 16 cupcake liners or spray the pan well with nonstick baking spray.
  2. Mix Wet Ingredients: In a large bowl, beat together the melted butter and light brown sugar until combined. Add in the egg, vanilla extract, mashed banana, and sour cream; beat again until smooth.
  3. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, cinnamon, and graham cracker crumbs.
  4. Mix Batter: Add the dry mixture alternately with the milk to the wet ingredients, stirring gently until just combined. Be careful not to overmix to keep muffins tender.
  5. Add Chocolate and Marshmallows: Fold in ¾ cup of chocolate chips and ¾ cup of miniature marshmallow bits by hand to evenly distribute.
  6. Fill Muffin Cups: Spoon the batter into the prepared liners, filling each about three-quarters full. Sprinkle the tops evenly with the remaining chocolate chips and marshmallow bits.
  7. Bake: Bake in the preheated oven for 16 minutes, or until a toothpick inserted in the center comes out clean and marshmallows are slightly toasted.
  8. Cool and Store: Allow muffins to cool in the pan for 3 to 4 minutes, then transfer to a wire rack to cool completely. Store muffins in a sealed container to maintain freshness.

Notes

  • Due to the low butter content, muffins may stick to liners on the first day; letting them sit overnight in a sealed container helps the liners come off easily.
  • You can also spray the muffin pan with non-stick spray and bake the batter without liners for easier removal.
  • Alternatively, bake the batter in a greased 9×5 loaf pan at 350°F for 60 minutes for a banana s’mores loaf.
