Ingredients You’ll Need

Graham Cracker Crust

• 1 1/2 cups graham crackers, crushed
• 1/3 cup sugar
• 5 tbsp melted butter

Cupcakes

• 1 box devil’s food chocolate cake mix
• 3 large eggs
• 1 cup buttermilk (or 1 cup milk + 1 tbsp vinegar, rested 10 minutes)
• 1/2 cup vegetable oil
• 1/2 cup mini chocolate chips
• Additional graham cracker crumbs for topping

Marshmallow Frosting

• 7 oz marshmallow creme
• 1 cup unsalted butter, softened
• 1 cup powdered sugar
• 1 tsp vanilla extract

Step-by-step Instructions

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

Step 2: Combine the crushed graham crackers and sugar in a small bowl. Melt the butter and stir it into the crumbs until the mixture holds together. To crush crackers, use a food processor, or place them in a sealed bag and crush with a rolling pin.

Step 3: Add about 1 tablespoon of the graham mixture to each liner and press down firmly (the back of a spoon or a small measuring cup works fine). Bake the crusts for 6–8 minutes, then remove them and cool on a wire rack for five minutes. Increase the oven temperature to 350°F.

Step 4: In a large bowl, mix the cake mix, eggs, buttermilk, and oil on low speed just until combined. Overmixing can make cupcakes dense—stop when the batter is smooth. If you don’t have buttermilk, combine 1 cup milk with 1 tablespoon vinegar or lemon juice and let it sit 10 minutes.

Step 5: Spoon the batter over the cooled graham cracker crusts, filling liners about 2/3 to 3/4 full. Sprinkle extra mini chocolate chips and a few graham cracker crumbs on top. Bake at 350°F for 12–14 minutes or until a toothpick comes out clean. Transfer the cupcakes to a wire rack and let them cool completely.

Step 6: For the frosting, cream the softened butter in a mixing bowl. Add the marshmallow creme and vanilla, mixing until smooth. Gradually add the powdered sugar, beating until the frosting is airy and spreadable.

Step 7: Frost cooled cupcakes using an offset spatula for a smooth finish or a piping bag for swirls. Garnish with extra chocolate chips and crushed graham crackers for texture and visual appeal. Serve and enjoy.

Tips and Frequently Asked Questions

How full should I fill the cupcake liners?

Fill liners about 2/3 to 3/4 full. Underfilling yields flat cupcakes; overfilling can cause overflow and uneven baking.

How do you make cupcakes light and fluffy?

Mix on low speed and only until ingredients come together to preserve the air bubbles that expand during baking. Avoid overmixing, which makes cupcakes dense.

Is marshmallow fluff the same as marshmallow creme?

They are similar but not identical. Marshmallow creme is smoother and creates a lighter frosting, while fluff may produce a slightly heavier texture. Use marshmallow creme for the silkiest frosting.

How to store and freeze s’mores cupcakes

• Unfrosted: Store at room temperature 4–5 days or in the fridge up to a week. For best texture, frost within two days.
• Frosted: Keep in an airtight container at room temperature for 4–5 days or refrigerated for up to a week. Best eaten within 2–3 days.
• Freezing unfrosted: Cool completely, wrap individually in plastic, and freeze in an airtight container for up to 4 months. Thaw in the fridge overnight.
• Freezing frosted: Freeze unfrosted cupcakes first, then frost, chill briefly, and wrap individually before storing in an airtight container for up to 4 months.

How to frost cupcakes

• Spreading: Use an offset spatula or butter knife, place a dollop of frosting in the center and spread outward in a circular motion for a smooth finish.
• Piping: Use a pastry bag or a snipped corner of a zip-top bag to pipe swirls. Start from the outside and spiral to the center.

Recipe Variations

• Peanut butter: Drizzle melted peanut butter on top for a peanut butter s’mores twist.
• Change the chocolate: Swap semisweet chips for dark or milk chocolate to suit your taste.
