Equipment Needed

• Muffin tin & cupcake liners – Essential for shaping the cupcakes.
• Mixing bowls – Needed for preparing the crust, cupcake batter, and frosting.
• Electric mixer – Helps achieve a smooth batter and fluffy buttercream.
• Piping bag & tips – For beautifully frosting the cupcakes.
• Kitchen torch – To give the marshmallow topping a toasted s’mores finish.
• Cooling rack – Ensures cupcakes cool completely before frosting.

Step-by-Step Instructions

1. Prepare the Graham Cracker Crust

Preheat your oven to 325°F (163°C). Line a muffin tin with cupcake liners. In a bowl, combine graham cracker crumbs, melted butter, and granulated sugar. Mix until the crumbs are evenly coated and resemble wet sand. Press about 1 tablespoon of the mixture into the bottom of each cupcake liner. Bake for 5 minutes, then set aside to cool.

2. Make the Coffee-Chocolate Cupcake Batter

Increase oven temperature to 350°F (177°C). In a large bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt. In another bowl, whisk eggs, granulated sugar, brown sugar, milk, coffee, vegetable oil, and vanilla extract until smooth. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

3. Bake the Cupcakes

Fill each cupcake liner ¾ full with batter, covering the graham cracker crust. Bake for 18-20 minutes or until a toothpick inserted in the center comes out clean. Let cupcakes cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

4. Prepare the Espresso Buttercream

In a mixing bowl, beat butter until creamy. Gradually add powdered sugar, one cup at a time, beating on low speed. Add brewed espresso, vanilla extract, and heavy cream, then beat on high for 2-3 minutes until fluffy.

5. Assemble the Cupcakes

Pipe the espresso buttercream onto cooled cupcakes using a piping bag fitted with a star tip. Spoon a dollop of marshmallow fluff on top of each cupcake and torch it lightly with a kitchen torch to create a toasted effect.

6. Garnish and Serve

Sprinkle with graham cracker crumbs, drizzle with chocolate syrup, and top with mini marshmallows for that final s’mores touch.

Tips and Variations

• No Kitchen Torch? Broil the cupcakes for 30 seconds to toast the marshmallow topping.
• Stronger Coffee Flavor? Add ½ tsp espresso powder to the cupcake batter.
• No Espresso Buttercream? Swap it with chocolate or vanilla frosting for a different flavor twist.
• Make It Boozy! Add 1 tbsp coffee liqueur (like Kahlúa) to the buttercream.
• Gluten-Free Option – Use gluten-free flour and graham cracker crumbs.

Serving Suggestions

Serve these cupcakes on a rustic wooden board with a drizzle of chocolate syrup and crushed graham crackers around them. Pair them with a warm latte, iced coffee, or hot chocolate for an extra indulgent experience.

For a party, set up a DIY cupcake bar with extra toppings like chocolate shavings, caramel drizzle, and crushed cookies for guests to customize their own!

Pairings

• Coffee Lovers’ Dream – Serve with a caramel macchiato or cold brew coffee for a double coffee kick.
• Sweet and Boozy – Try with a Baileys Irish Cream latte or espresso martini for a more grown-up dessert.
• Classic Combo – A glass of milk or a mug of hot cocoa enhances the s’mores experience.

Storage and Reheating

• Refrigerate cupcakes in an airtight container for up to 4 days.
• Freeze unfrosted cupcakes for up to 2 months; thaw before frosting.
• To Refresh – Microwave for 5-10 seconds to soften before serving.
