How to Make Banana S’mores Muffins
Step 1: Prepare your pan and oven
Start by preheating your oven to 400°F. Line a muffin pan with 16 cupcake liners or spray the pan thoroughly with nonstick baking spray. This step ensures your muffins will bake evenly and come out easily without sticking.
Step 2: Combine wet ingredients
In a mixing bowl, beat together melted butter and light brown sugar until smooth and glossy. Then add the egg, vanilla, mashed banana, and sour cream. Beat again until everything is well combined, creating a rich and creamy base for your batter.
Step 3: Mix dry ingredients
In a separate bowl, stir together the flour, baking powder, baking soda, salt, cinnamon, and graham cracker crumbs. This dry mixture is packed with the flavors and lifting agents that make each muffin perfectly tender and flavorful.
Step 4: Combine wet and dry mixtures
Alternately add the dry ingredients and whole milk to the wet mixture, starting and ending with the dry. Stir gently and stop as soon as the flour disappears – over-mixing will make your muffins tough instead of tender.
Step 5: Add chocolate chips and marshmallow bits
Fold in 3/4 cup of miniature chocolate chips and 3/4 cup of marshmallow bits by hand. This soft mixing keeps these treats evenly distributed throughout the batter without smashing them.
Step 6: Fill muffin liners and top
Use a spoon or scoop to fill each muffin liner with batter, then sprinkle the tops with the remaining chocolate chips and marshmallow bits. This top layer will caramelize and give extra gooey, melty texture after baking.
Step 7: Bake and cool
Bake your Banana S’mores Muffins for 16 minutes until golden and a toothpick inserted comes out clean. Let them cool in the pan for about 3 to 4 minutes before transferring to a wire rack to cool completely. This resting lets them set up perfectly while keeping the gooey charm inside.
How to Serve Banana S’mores Muffins

Garnishes
Add a light dusting of powdered sugar or a drizzle of melted chocolate on top to elevate the presentation. For an extra festive touch, sprinkle a few extra mini marshmallows and crushed graham cracker crumbs over the top right before serving to keep that s’mores vibe alive.
Side Dishes
Pair these muffins with fresh fruit or a dollop of vanilla Greek yogurt for a balanced breakfast. If serving as a snack, a warm cup of coffee, hot chocolate, or milk makes a perfect companion to these sweet treats.
Creative Ways to Present
For a fun twist, cut a Banana S’mores Muffin in half, toast lightly under the broiler to melt the marshmallows and chocolate, then sandwich with a thin layer of peanut butter or Nutella. These “muffin sandwiches” bring a creative flair and an extra burst of richness.
Make Ahead and Storage
Storing Leftovers
Store leftover Banana S’mores Muffins in an airtight container at room temperature for up to 3 days. They maintain their softness and flavor best when kept sealed away from air.
Freezing
You can freeze these muffins for longer storage. Wrap each muffin individually in plastic wrap or aluminum foil, then place in a freezer-safe bag or container. They freeze well for up to 3 months without losing their delicious texture.
Reheating
To enjoy, simply thaw at room temperature or gently warm in the microwave for about 20 seconds. For that fresh-baked feel, pop them into a preheated oven at 350°F for 5-7 minutes to restore the melty marshmallow goodness and warm chocolate chips.
FAQs
Can I use mashed bananas that are not very ripe?
Riper bananas are best because they bring more natural sweetness and moisture to your Banana S’mores Muffins. If your bananas aren’t very ripe, the muffins might be less sweet and a bit denser, so try to use soft, spotty bananas for best results.
What can I substitute for sour cream?
If you don’t have sour cream, plain Greek yogurt or buttermilk work as excellent substitutes. Both add moisture and tenderness while preserving the delicate tang that balances the sweetness.
Can I make these muffins gluten-free?
Absolutely! Replace the all-purpose flour with a 1-to-1 gluten-free baking blend, making sure it contains xanthan gum for structure. Keep the other ingredients the same for equally delicious Banana S’mores Muffins.
What’s the difference between using baking powder and baking soda here?
Both are leavening agents but work differently. Baking soda reacts with the acidic sour cream and banana to create lift, while baking powder provides additional rise for a lighter texture. Using both ensures fluffy muffins with great crumb.
Can I add nuts or other mix-ins?
Definitely! Chopped walnuts or pecans add a wonderful crunch that pairs nicely with the banana and s’mores flavors. Just fold in about 1/2 cup along with the chocolate chips and marshmallows.
