Recipe Details
- Flavor Profile: A nostalgic blend of sweet ripened bananas, warm cinnamon, toasted honey-graham notes, and rich chocolate.
- Textures: Incredibly moist and fluffy cake with a slight graininess from the graham cracker crumbs and gooey pockets of melted marshmallow.
- Total Time: Approximately 25-30 minutes (10 minutes prep + 16 minutes bake).
- Difficulty: Easy – a straightforward mixing process that uses standard muffin pans.
What You’ll Need
To create these muffins, you will need a base of ripe bananas and sour cream to ensure a moist texture. The S’mores element is achieved by incorporating graham cracker crumbs directly into the flour mixture, while miniature chocolate chips and marshmallow bits are folded in at the end to create those signature campfire flavors.
Ingredient Notes
- Ripe Bananas – The more brown spots, the better. Ripe bananas provide the best natural sweetness and moisture for the batter.
- Sour Cream – This is the secret to a professional-style muffin. It adds fat and acidity, which keeps the crumb tender and prevents it from being dry.
- Graham Cracker Crumbs – These are mixed into the dry ingredients to give the muffins a distinct honey-wheat flavor that mimics a s’more crust.
- Marshmallow Bits – It is recommended to use the small, crunchy “mallows” often found in hot cocoa mixes, as they hold their shape better during baking than standard soft miniature marshmallows.
Add-ins and Substitutions
- Nuts – If you like a crunch, feel free to add 1/2 cup of chopped walnuts or pecans to the batter.
- Chocolate Variety – While miniature milk chocolate chips are classic for s’mores, dark chocolate chips or white chocolate chips can be used for a different flavor profile.
- Yogurt – If you are out of sour cream, plain Greek yogurt is an excellent 1:1 substitute that maintains the moisture level of the muffin.
How to Make Banana S’mores Muffins
The key to these muffins is the alternating mixing method, which ensures the batter stays light and airy.
- Prep the Oven and Pan: Preheat your oven to 400°F. Line your muffin pan with 16 cupcake liners or spray the pan thoroughly with non-stick baking spray.
- Cream the Wet Ingredients: In a large bowl, beat together the melted butter and brown sugar. Add the egg, vanilla extract, mashed bananas, and sour cream, then beat again until well combined.
- Combine Dry Ingredients: In a separate bowl, stir together the all-purpose flour, baking powder, baking soda, salt, cinnamon, and graham cracker crumbs.
- Mix the Batter: Add the flour mixture to the wet ingredients alternately with the whole milk. Mix until just combined, being careful not to over-mix, as this can lead to tough muffins.
- Fold in S’mores Elements: By hand, gently stir in 3/4 cup of the chocolate chips and 3/4 cup of the marshmallow bits.
- Fill and Bake: Divide the batter into the prepared liners. Sprinkle the tops with the remaining 1/4 cup of chocolate chips and 1/4 cup of marshmallows. Bake for exactly 16 minutes at 400°F.
- Cool: Allow the muffins to cool in the pan for 3-4 minutes. This allows them to set slightly so they don’t tear. Move them to a wire rack to cool completely.
Pro Tip: When mixing the dry and wet ingredients, use a light hand. Only stir until no more streaks of white flour are visible. Over-mixing develops too much gluten, which will make your muffins dense rather than fluffy.
Recipe Tips
- Room Temperature Ingredients: Try to have your egg and milk at room temperature before mixing to help the batter emulsify more smoothly.
- Don’t Peek: Keep the oven door closed during the 16-minute bake time. Opening the door can cause the temperature to drop and the muffins to sink.
- Filling the Liners: For even baking, fill the liners about 3/4 of the way full. This leaves enough room for the muffins to rise and form a perfect dome.
- Marshmallow Placement: Pressing a few extra marshmallows onto the top after the muffins are baked but still hot can give them a beautiful “just-toasted” look.
FAQs
Can I use regular mini marshmallows? You can, but be aware that standard soft marshmallows tend to melt into the batter and disappear or leave sticky holes. Miniature marshmallow bits (the crunchy kind) stay intact better during the baking process.
How do I store these? Store these in an airtight container at room temperature. They stay fresh and moist for up to 3-4 days.
Can I freeze these muffins? Yes. Once completely cooled, wrap them individually in plastic wrap and store them in a freezer bag for up to 3 months. Thaw at room temperature or warm them briefly in the microwave.
Serving Suggestions
- Morning Coffee: These are a fantastic accompaniment to a dark roast coffee or a latte.
- Afternoon Snack: Serve them slightly warm so the chocolate chips are still melty.
- With Toppings: A small smear of peanut butter or almond butter on a halved muffin adds a delicious savory element.
Make This Recipe in Advance
You can mash the bananas and mix the dry ingredients (flour, baking powder, soda, salt, cinnamon, and graham crumbs) the night before. Store the mashed bananas in an airtight container in the fridge. In the morning, simply combine the wet and dry components for a fresh, hot breakfast in less than 20 minutes.

Description
A delightful twist on a classic campfire treat, combining sweet banana bread with toasted marshmallows, melting chocolate, and graham crackers. These muffins feature a moist, tender crumb infused with cinnamon and graham cracker crumbs for a touch of nostalgia in every bite.
Ingredients
- 2/3 cup light brown sugar, 2/3 cup mashed ripe banana
- 2 cups all-purpose flour, 3/4 cup graham cracker crumbs
- 1/2 cup sour cream, 2/3 cup whole milk
- 2 tbsp unsalted butter (melted), 1 egg, 1 tsp vanilla
- 2 tsp baking powder, 1 tsp baking soda, 1/2 tsp salt, 1 tsp cinnamon
- 1 cup mini chocolate chips (divided), 1 cup mini marshmallow bits (divided)
Instructions
Prep: Preheat oven to 400°F. Line a muffin pan with 16 liners.
Wet Mix: Beat melted butter and brown sugar. Add egg, vanilla, mashed bananas, and sour cream; beat until combined.
Dry Mix: Stir together flour, baking powder, baking soda, salt, cinnamon, and graham cracker crumbs in a separate bowl.
Combine: Add dry ingredients to wet mixture alternately with milk. Stir until just combined do not over-mix.
Fold & Bake: Fold in 3/4 cup each of chips and marshmallows. Fill liners 3/4 full; top with remaining chips/marshmallows. Bake for 16 mins. Cool in pan for 3–4 mins before moving to a rack.
Notes
Marshmallow Choice: Use crunchy ‘mallow bits’ (like in hot cocoa). Standard soft marshmallows melt too quickly and leave sticky, empty holes in the muffins.
The Sour Cream Secret: Sour cream provides the fat and acidity needed for a tender, bakery-style crumb that stays moist for days.
Don’t Over-mix: Stop stirring once flour streaks disappear. Over-mixing develops gluten, which results in a rubbery, dense muffin texture.
