Easy S’mores Cupcake Recipe with Cake Mix:

I love s’mores, but on hot summer nights building a fire isn’t always practical. These s’mores cupcakes capture the same flavors without the mess or the risk of burnt marshmallows. A crisp graham cracker base, moist chocolate cupcake, and cloud-like marshmallow frosting make for a perfect summer dessert.

Although they may look fancy, this recipe is straightforward. Follow the steps below for an easy, step-by-step guide to recreate s’mores in cupcake form.

Are Homemade S’mores Cupcakes Easy to Make?

Yes. These are one of the easiest ways to enjoy s’mores flavors at home. They require minimal effort and deliver big flavor — all without an open flame. The end result is a safe, delicious treat that feels special but is simple to prepare.

Ingredients You’ll Need:

Graham Cracker Bottom Crust

• Graham crackers — for the crunchy base.
• Sugar — adds sweetness to the crust.
• Melted butter — binds the crumbs together.

Cupcakes

• Devil’s food chocolate cake mix — for a rich, chocolatey cake.
• Eggs — help bind and structure the cupcakes.
• Buttermilk and vegetable oil — keep the cupcakes moist.
• Chocolate chips — add extra chocolate texture and pockets of melty goodness.
• Graham cracker crumbs — a little mixed into the batter gives extra crunch.

Frosting

• Marshmallow creme — creates a light, fluffy frosting.
• Butter — provides body and creaminess.
• Powdered sugar — sweetens and stabilizes the frosting.
• Vanilla extract — enhances the marshmallow flavor.

Step 1: Preheat the oven to 325°F. Line a 12-cup muffin tin with cupcake liners or grease the tin if you prefer. Parchment liners work well and don’t need greasing.

Step 2: In a small bowl, combine crushed graham crackers and sugar. Melt the butter and stir it into the crumbs until evenly moistened.

Tip: To crush graham crackers, place them in a sealed bag and crush with a rolling pin, or pulse them in a food processor until coarse crumbs form.

Step 3: Spoon about 1 tablespoon of the graham cracker mixture into each liner and press firmly to form a crust. A small measuring cup, the back of a spoon, or a tart shaper works well. Bake 6–8 minutes, then remove and let the crusts cool on a wire rack for about five minutes.

Step 4: Increase oven temperature to 350°F. In a large bowl, combine the boxed cake mix, eggs, buttermilk, and oil. Mix on low speed just until smooth — avoid overmixing to keep cupcakes light and tender. An electric mixer helps, but a whisk works too.

How do you make cupcakes light and fluffy?

The air incorporated into the batter expands during baking and produces a light texture. Mix only until ingredients are combined and avoid overbeating, which makes cupcakes dense. If you don’t have buttermilk, make a substitute by combining 1 cup milk with 1 tablespoon vinegar or lemon juice; let sit 10 minutes to thicken.

Step 5: Divide the batter over the cooled graham cracker crusts, filling each liner about 2/3 to 3/4 full. Sprinkle extra mini chocolate chips and graham cracker crumbs on top if desired. Bake 12–14 minutes, or until a toothpick inserted in the center comes out clean. Cool completely on a wire rack before frosting.

Step 6: Make the frosting: cream softened butter in a large bowl, then add marshmallow creme and vanilla extract and mix until smooth. Gradually add powdered sugar and beat until the frosting is light and spreadable.

Is marshmallow fluff the same as marshmallow creme?

They are similar but not identical. Marshmallow creme yields a smooth, spreadable frosting. Fluff can be thicker and slightly heavier; choose based on the texture you prefer for your cupcakes.

Step 7: Frost the cooled cupcakes and decorate with extra chocolate chips and graham cracker crumbs. Serve and enjoy!

A s’mores cupcake on a warm evening is a delicious way to enjoy summer flavors without a campfire.

How full should I fill my cupcake liners?

Fill liners about 2/3 to 3/4 full. Underfilling yields flat cupcakes with too much frosting; overfilling spills and overflows during baking.

How to store s’mores cupcakes

• Unfrosted cupcakes: store at room temperature for 4–5 days or in the refrigerator up to a week. For best texture, frost within two days.
• Frosted cupcakes: keep in an airtight container for 4–5 days at room temperature or up to a week refrigerated. They’re best within 2–3 days.
• Freezing unfrosted cupcakes: cool completely, wrap individually in plastic wrap, and place in an airtight container or freezer bag for up to 4 months. Thaw in the fridge overnight or at room temperature.
• Freezing frosted cupcakes: freeze unfrosted first, then frost and chill on a plate in the freezer for about an hour. Wrap individually and store in an airtight container for up to 4 months.

How do you frost cupcakes?

• Spreading: use an offset spatula or butter knife. Dollop frosting in the center and spread outward in a circular motion for a smooth finish.
• Piping: fill a pastry bag or a Ziploc bag with frosting, snip a corner, and pipe a swirl beginning at the outer edge and working toward the center.

Variations to this Recipe:

• Peanut butter: drizzle melted peanut butter over the frosting for a peanut-butter s’mores twist.
• Change the chocolate: swap semisweet chips for dark or milk chocolate to suit your taste.
