Ingredients
- 2/3 cup packed light brown sugar
- 2 tablespoons unsalted butter, melted
- 1 large egg
- 1 teaspoon vanilla extract
- 2/3 cup mashed ripe banana (2 medium-sized)
- 1/2 cup sour cream
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1/2 teaspoon table salt
- 1 teaspoon cinnamon
- 3/4 cup graham cracker crumbs
- 2/3 cup whole milk
- 1 cup miniature chocolate chips, divided
- 1 cup miniature marshmallow bits, divided
Instructions
- Step 1: Preheat the oven to 400°F. Line a muffin pan with 16 cupcake liners or spray the pan well with nonstick baking spray.
- Step 2: In a bowl, beat together the melted butter and brown sugar until combined. Add the egg, vanilla extract, mashed banana, and sour cream, beating again until smooth.
- Step 3: In a separate bowl, stir together the flour, baking powder, baking soda, salt, cinnamon, and graham cracker crumbs.
- Step 4: Add the flour mixture to the wet ingredients alternately with the milk, mixing until just combined. Be careful not to over-mix the batter.
- Step 5: Gently fold in 3/4 cup of the chocolate chips and 3/4 cup of the marshmallow bits by hand.
- Step 6: Fill the muffin liners evenly with batter. Sprinkle the remaining chocolate chips and marshmallow bits on top of each muffin.
- Step 7: Bake for 16 minutes, until a toothpick inserted in the center comes out clean. Allow muffins to cool in the pan for 3-4 minutes before transferring to a wire rack to cool completely.
Tips & Variations
- For extra moisture and a richer flavor, try substituting half the sour cream with Greek yogurt.
- Swap the miniature chocolate chips for white chocolate or butterscotch chips for a different taste.
- If you prefer, use mini marshmallows instead of marshmallow bits—just be aware they may melt more during baking.
- To enhance the banana flavor, add a teaspoon of mashed banana extract or a pinch of nutmeg along with the cinnamon.
Storage
Store the banana muffins in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to one week or freeze for up to 3 months. Reheat refrigerated or thawed muffins in the microwave for about 15 seconds for a warm, soft texture.

FAQs
Can I use overripe bananas for this recipe?
Absolutely. Overripe bananas with lots of brown spots are perfect because they are sweeter and mash easily, enhancing the muffin’s flavor and moistness.
Can I make these muffins gluten-free?
Yes, substitute the all-purpose flour with a gluten-free baking blend that includes xanthan gum. The texture may vary slightly but should still produce delicious muffins.
