Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Muffins:
1 ½ cups all-purpose flour
1 teaspoon baking powder
½ teaspoon baking soda
¼ teaspoon salt
1 teaspoon cinnamon (optional)
3 ripe bananas, mashed
⅓ cup vegetable oil or melted butter
½ cup granulated sugar
1 large egg
1 teaspoon vanilla extract
½ cup mini chocolate chips
½ cup graham cracker crumbs

For the Topping:
Mini marshmallows
Extra graham cracker crumbs for sprinkling

Directions

1. Preheat oven: Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or lightly grease it.
2. Mix dry ingredients: In a medium bowl, whisk together flour, baking powder, baking soda, salt, and cinnamon.
3. Mix wet ingredients: In a large mixing bowl, mash the bananas. Add oil (or melted butter), sugar, egg, and vanilla extract. Stir until well combined and smooth.
4. Combine: Gradually fold the dry ingredients into the wet mixture, mixing until just combined. Avoid overmixing to keep the muffins tender. Gently fold in mini chocolate chips and graham cracker crumbs.
5. Fill muffin cups: Spoon the batter evenly into the muffin cups, filling each about three-quarters full.
6. Bake: Bake for 18–22 minutes, or until a toothpick inserted in the center of a muffin comes out clean (avoid the marshmallow topping area).
7. Add marshmallow topping: Remove the muffins from the oven and top each one with mini marshmallows. Place under the broiler for 1–2 minutes, watching closely until the marshmallows are lightly golden and toasted. Sprinkle extra graham cracker crumbs over the top.
8. Cool and serve: Let the muffins cool slightly before serving. Enjoy them warm for the perfect gooey texture.

FAQs

How ripe should the bananas be for this recipe?

Use very ripe bananas with brown spots on the peel for the best sweetness and texture.

Can I use butter instead of vegetable oil?

Yes, melted butter works perfectly and adds a rich flavor to the muffins.

Can I make these muffins gluten-free?

Yes, substitute the all-purpose flour with a 1:1 gluten-free baking blend.

Can I use large marshmallows instead of mini ones?

You can, but cut them into smaller pieces so they melt evenly and don’t overpower the muffin.

Do I need to broil the marshmallows?

Broiling gives them that toasted, s’mores-style finish, but you can skip it if you prefer softer marshmallows.

Can I use brown sugar instead of granulated sugar?

Yes, brown sugar will add a deeper, caramel-like sweetness.

Can I make these muffins vegan?

Yes, replace the egg with a flax egg and use plant-based butter or oil along with vegan chocolate chips and marshmallows.

How can I tell when the muffins are fully baked?

A toothpick inserted in the center should come out clean with a few moist crumbs attached.

Can I prepare the batter ahead of time?

It’s best to bake the muffins immediately after mixing to ensure they rise properly.

What’s the best way to serve these muffins?

Serve them slightly warm with melted chocolate drizzled on top or alongside a glass of milk or coffee.
