Introduction: The Best Gooey S'mores Cupcakes

Delicious chocolate filled cupcake, with a marshmallow on top, tastes like summer

Step 1: Chocolate Butter Cream Filling

Start buttercream about an hour before your cupcakes

1. In a small saucepan over medium heat place PYREX bowl with butter and chocolate until melted

2. Allow to cool on the counter for 10 minutes then place in refrigerator until solid, about 1 hour.

2 Hershey's Bars 3 oz of chocolate
8 tablespoons (4oz) unsalted butter

Step 2: Graham Cracker Layer

1. Preheat oven to 350° Line cupcake pan with grease-proof liners.

2. In your food processor, pulse graham cracker pieces until they are a fine crumb. Add in flour and sugar and pulse until combined. Drizzle in butter and continue to process until completely incorporated. If you don't have a food processor, you can crush the graham crackers with a rolling pin in a plastic bag and mix everything in a bowl.

3. Divide graham cracker mixture between cupcakes cups, a little less than one tablespoon per cup, and use your fingers or a shot glass to press the mixture down firmly.

4. Bake for 5 minutes until tops look set.

  • 1/4 cup graham cracker crumbs (2 1/2) graham crackers
  • 1/4 cup (30g) all-purpose flour
  • 2 tablespoons (25g) brown sugar
  • 3 tablespoons (1.5oz) melted butter

Step 3: Cupcakes

  • 4 tablespoons (2oz) unsalted butter
  • 1/4 cup (1.5oz) semi-sweet chocolate chopped (high-quality chips are fine)
  • 1 tablespoon vegetable oil
  • 1/2 cup (60g) all-purpose flour
  • 1/4 cup (20g) unsweetened cocoa powder sifted
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup (100g) granulated sugar
  • 1 large egg and 1 large egg yolk at room temperature
  • 1/2 teaspoon vanilla extract
  • 1/4 cup buttermilk
  • 1/4 cup hot coffee or hot water

  1. In a medium microwave-safe bowl, microwave butter until almost completely melted. Add chocolate and oil and microwave for 30 seconds. Stir. Microwave for an additional 15 seconds if necessary, until chocolate is completely melted. Stir until well-combined and set aside to cool.
  2. In a medium bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
  3. In a large bowl, whisk together sugar, eggs, and vanilla extract. Whisk in cooled chocolate mixture. (It can be warm, but if it is hot to the touch, set aside for another couple of minutes. You don't want to scramble the eggs!)
  4. Whisk in half of the flour mixture until just combined. Add all of the buttermilk and mix. Whisk in the last of the flour, mixing until just combined.
  5. Whisk in the coffee (or water). The batter will be thin and runny. It's supposed to look like that.
  6. Fill cupcake tins just under 3/4 of the way full (if you transfer the batter to a liquid measuring cup first, it makes filling easier). Don't overfill--you might have a tiny bit of batter left over.
  7. Bake for 15-18 minutes, until a toothpick inserted into the center of the cupcakes, comes out clean. Take chocolate frosting mixture out of the refrigerator and set on the counter to soften while your cupcakes cool.

Step 4: Finish Chocolate Filling and Assemble

Allow cupcakes to cool completely, about half an hour. Once cupcakes are cool, use a handheld electric mixer, or scoop softened chocolate mixture into the bowl of your stand mixer and use the whisk attachment, to whisk mixture on medium-high until light in color, about 2 minutes.

Using a serrated knife with a sharp tip, cut a cone-shaped piece out of the center of each cupcake. You don't have to be neat about it, and you can discard (or eat) the cone.

Transfer chocolate frosting to a plastic bag by placing the bag over an empty cup and scooping the mixture inside. Seal bag and snip off one of the corners. Use the bag to "pipe" chocolate mixture into the cupcakes and fill to the top.

Step 5: Marshmallow Frosting

Place a marshmallow on top of the cupcake and put in the oven until it starts to puff up, about 5 minutes

  • monitor the whole time so they don't get too puffed
