How to Make Banana S’mores Muffins Recipe
Step 1: Prepare Your Oven and Muffin Pan
Start by preheating your oven to a toasty 400°F. Line a 12-cup muffin tin with cupcake liners to keep your muffins from sticking and to make cleanup a breeze. This simple preparation sets the stage for perfectly baked treats.
Step 2: Mix the Wet Ingredients
In a mixing bowl, combine the melted butter and light brown sugar, beating them together until they are fully blended and smooth. Then add in your egg, vanilla extract, mashed ripe bananas, and sour cream. Mix everything until the batter looks silky and consistent. These ingredients give your muffins a moist base and beautiful flavor foundation.
Step 3: Combine Dry Ingredients Separately
In another bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, cinnamon, and graham cracker crumbs. This dry mixture brings structure, lift, and that quintessential s’mores crunch to your muffins.
Step 4: Blend Wet and Dry Ingredients
Gradually incorporate your dry mix into the wet ingredients, alternating with whole milk. Be sure to mix gently just until everything is combined—overmixing can toughen your muffins. This careful folding ensures a soft, tender crumb.
Step 5: Fold in Chocolate Chips and Marshmallow Bits
Reserve a quarter of the chocolate chips and marshmallow bits for topping, then fold the rest into the batter. This step distributes the gooey surprises evenly, so you get pockets of chocolate and sweet marshmallow in every bite.
Step 6: Fill Muffin Cups and Add Toppings
Use a spoon or scoop to evenly divide the batter between the cupcake liners. Top each muffin generously with the remaining chocolate chips and marshmallow bits. They will toast nicely as the muffins bake, giving an irresistible golden crust.
Step 7: Bake to Golden Perfection
Bake in your preheated oven for about 16 minutes, or until the tops are golden brown and a toothpick inserted comes out clean. The aroma that fills your kitchen at this point is pure magic — a warm invitation to indulge.
Step 8: Cool and Enjoy
Let the muffins cool in their pan for a few minutes before transferring them to a wire rack. Cooling slightly will help set their texture, making them easier to handle and perfect for enjoying warm or room temperature.
How to Serve Banana S’mores Muffins Recipe

Garnishes
These muffins are delicious on their own, but sprinkle a little extra graham cracker crumbs or a dash of cinnamon on top just before serving for an extra hint of flavor and crunch. A light drizzle of honey or a smear of butter can elevate them even further.
Side Dishes
Pair your Banana S’mores Muffins with a cold glass of milk or a cup of coffee for an energizing breakfast or snack. Fresh fruit, such as berries or sliced apples, can balance the sweetness beautifully and add a refreshing contrast.
Creative Ways to Present
Serve these muffins warm out of the oven alongside a small bowl of vanilla yogurt or even softened cream cheese mixed with a touch of honey. For a fun twist at a brunch, offer a toppings bar with extra chocolate chips, marshmallow bits, chopped nuts, and caramel drizzle.
Make Ahead and Storage
Storing Leftovers
You can store leftover Banana S’mores Muffins in an airtight container at room temperature for up to three days. To keep them moist and soft, place a slice of bread or a damp paper towel inside the container — it helps maintain moisture balance.
Freezing
These muffins freeze beautifully. Wrap each muffin individually in plastic wrap or aluminum foil, then place them in a freezer-safe bag or container for up to two months. When you want a quick treat, simply thaw at room temperature.
Reheating
To enjoy your muffins warm after storage, pop them in a 350°F oven for about 8 minutes or microwave for 20-30 seconds. This reheating revives their soft texture and melty chocolate goodness as if freshly baked.
FAQs
Can I use frozen bananas for this recipe?
Absolutely! Frozen bananas work wonderfully as long as they are fully thawed and well mashed before using. They will add the same natural sweetness and moisture to your Banana S’mores Muffins Recipe.
What if I don’t have graham cracker crumbs?
You can substitute crushed digestive biscuits or even finely crushed cereal like cinnamon toast crunch to create a similar texture and flavor profile.
Can I make these muffins dairy-free?
Yes, you can swap the butter for a dairy-free alternative and use a plant-based sour cream or yogurt. Just make sure your milk substitute is unsweetened to avoid altering the flavor too much.
How ripe should the bananas be?
Use bananas that are very ripe with spots for the best sweetness and flavor. Under-ripe bananas might make your muffins less moist and flavorful.
Can I add nuts or other mix-ins?
Definitely! Chopped walnuts, pecans, or even a sprinkle of shredded coconut would complement the s’mores flavors nicely. Just fold them in at the same stage as the chocolate chips and marshmallow bits.

Add-ins
- 1 cup miniature chocolate chips, divided
- 1 cup miniature marshmallow bits, divided
Instructions
- Preheat and Prepare: Preheat your oven to 400°F (204°C) and line a muffin pan with cupcake liners to prevent sticking and make removal easy.
- Mix Wet Ingredients: In a mixing bowl, beat together the melted butter and light brown sugar until well combined. Then add the egg, vanilla extract, mashed banana, and sour cream; mix everything until the batter is smooth and well blended.
- Combine Dry Ingredients: In another bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, cinnamon, and graham cracker crumbs to ensure even distribution of leavening agents and spices.
- Incorporate Dry and Wet: Gradually add the dry ingredients to the wet mixture, alternating with the whole milk. Stir gently until just combined to avoid overmixing, which can make muffins tough.
- Add Chocolate and Marshmallows: Carefully fold in three-fourths of the miniature chocolate chips and marshmallow bits, evenly distributing these flavorful additions without deflating the batter.
