Ingredients

Scale
  • ⅔ cup packed light brown sugar

  • 2 tbsp unsalted butter, melted (or coconut oil)

  • 1 large egg (or flax egg: 1 tbsp flax + 3 tbsp water)

  • 1 tsp vanilla extract

  • ⅔ cup mashed ripe banana (≈2 spotty bananas)

  • ½ cup sour cream (or plain yogurt/buttermilk)

  • 2 cups all-purpose flour (or 1:1 GF blend + ½ tsp xanthan gum)

  • 2 tsp baking powder + 1 tsp baking soda

  • ½ tsp salt

  • 1 tsp cinnamon

  • ¾ cup graham cracker crumbs (about 6 sheets)

  • ⅔ cup whole milk

  • 1 cup mini chocolate chips, divided

  • 1 cup mini marshmallow bits, divided


Instructions

1️⃣ Prep: Preheat oven to 350°F (175°C). Line muffin tin with paper liners and lightly spray for easy release.
2️⃣ Wet Mix: In a large bowl, whisk sugar + melted butter. Add egg + vanilla. Stir in mashed banana + sour cream.
3️⃣ Dry Mix: In another bowl, whisk flour, baking powder, baking soda, salt, cinnamon, graham crumbs.
4️⃣ Combine: Stir dry ingredients into wet in thirds, alternating with milk. Stop at just combined.
5️⃣ Fold: Gently fold in ¾ cup chocolate chips + ¾ cup marshmallows (tossed in a bit of flour).
6️⃣ Fill & Top: Spoon into muffin cups ¾ full. Sprinkle remaining chocolate + marshmallows on top, press lightly.
7️⃣ Bake: 18–22 mins, rotating halfway. Tent with foil if marshmallows brown too fast. Done when tops spring back + toothpick is clean (ignore melted chocolate).
8️⃣ Cool: Rest in tin 5 mins, then move to rack. Enjoy warm!

Notes

  • Freeze marshmallows 10 mins for easier chopping.

  • Measure flour by spooning, not scooping—no dense muffins!

  • Broil 60 sec after baking for extra toasty tops.
