Ingredients

• ⅔ cup packed light brown sugar
• 2 tablespoons unsalted butter, melted
• 1 large egg
• 1 teaspoon vanilla extract
• ⅔ cup mashed ripe banana (about 2 medium bananas)
• ½ cup sour cream
• 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
• ⅔ cup whole milk
• 1 cup miniature chocolate chips, divided
• 1 cup miniature marshmallow bits, divided

These ingredients combine to create muffins that are moist, tender, and packed with flavor. Brown sugar adds subtle caramel notes, while cinnamon provides a warm, cozy flavor. Graham cracker crumbs contribute texture and a nod to classic s’mores. Chocolate chips and marshmallow bits bring sweetness and gooeyness, making each bite a little indulgent but irresistibly delicious.

Step-by-Step Method

Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with paper liners or lightly grease it. In a medium bowl, whisk together the brown sugar, melted butter, egg, and vanilla extract until smooth and combined. Add the mashed bananas and sour cream, mixing until evenly incorporated. In a separate bowl, sift together the all-purpose flour, baking powder, baking soda, salt, and cinnamon. Add the graham cracker crumbs to the flour mixture and stir to combine.

Gradually fold the dry ingredients into the wet mixture, alternating with the whole milk, beginning and ending with the dry ingredients. Mix until just combined; do not overmix to keep the muffins light and tender. Fold in half of the miniature chocolate chips and half of the marshmallow bits into the batter, reserving the remaining chocolate and marshmallows for topping.

Spoon the batter evenly into the prepared muffin cups, filling each about 3/4 full. Sprinkle the reserved chocolate chips and marshmallow bits on top of each muffin for a melty, gooey finish. Bake in the preheated oven for 18–22 minutes, or until a toothpick inserted into the center comes out clean or with just a few crumbs. Avoid overbaking to maintain a soft, moist texture.

Remove the muffins from the oven and allow them to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely. The warm chocolate and marshmallows on top will slightly melt, creating an irresistible s’mores effect. Serve the muffins warm for maximum gooeyness, or store them in an airtight container at room temperature for up to 3 days.

Tips for Perfect Muffins

Use very ripe bananas for natural sweetness and maximum flavor. Be careful not to overmix the batter, as this can make the muffins dense. For extra gooey s’mores texture, slightly underbake the muffins and allow residual heat to finish cooking. You can toast the marshmallow bits lightly under a broiler for a golden, caramelized effect. Use fresh, high-quality chocolate chips for better melt and flavor.

Serving Suggestions

These muffins are perfect for breakfast or brunch alongside a cup of coffee, hot chocolate, or a glass of milk. They also make a fun dessert for parties, potlucks, or school events. Serve them warm to enjoy the melted chocolate and marshmallow bits at their gooey best. You can also slice the muffins in half and toast them lightly for a unique treat. They pair wonderfully with yogurt, fresh fruit, or nut butter for a more filling breakfast.

Variations

Swap in dark or semi-sweet chocolate chips for a richer flavor. Add chopped nuts, such as walnuts or pecans, for extra texture and a nutty contrast. Mix in shredded coconut for a tropical twist or drizzle melted chocolate over the cooled muffins for a decadent finish. You can also experiment with different spices like nutmeg or allspice to enhance the warmth and depth of flavor. For a fun twist, add a small piece of chocolate or marshmallow in the center of each muffin before baking for a hidden gooey surprise.
