Ready to transform these simple ingredients into a show-stopping dessert? Follow these clear, detailed steps to achieve perfectly baked cupcakes with that classic s’mores finish.
1. Preheat the oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners. Ensuring the oven reaches the correct temperature before baking guarantees an even rise and consistent crumb throughout.
2. In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Sifting removes lumps and incorporates air, resulting in a lighter, more uniform batter.
3. In another bowl, whisk the buttermilk, vegetable oil, egg, and vanilla extract until well combined. This wet mixture brings moisture and richness, making every bite tender.
4. Gradually add the wet ingredients to the dry ingredients, mixing until the batter is smooth. Take care not to overmix—just enough to combine for a soft, fluffy texture.
5. Stir in the boiling water until fully incorporated. The thin batter is normal; it helps produce a moist, fudgy crumb.
6. Place a graham cracker square at the bottom of each cupcake liner. This creates a delightful crunch that echoes the classic campfire treat.
7. Pour a generous scoop of the chocolate batter over each graham cracker until they are 2/3 full. This ensures space for the cupcakes to rise without spilling over.
8. Add a few chocolate chips on top of the batter in each cup. These will melt into gooey pockets of rich chocolate as they bake.
9. Bake for 18–20 minutes or until a toothpick inserted into the center of a cupcake comes out clean. Watch the color—cupcakes should look set but still moist.
10. Remove cupcakes from the oven and turn on the broiler setting. This step readies the oven for the perfect marshmallow toast.
11. Place 2 marshmallows on top of each cupcake and return to the oven. Watch carefully and broil until the marshmallows are golden brown, about 1–2 minutes. They should puff and develop a toasted exterior without burning.
12. Remove and allow cupcakes to cool slightly. Optionally, sprinkle more graham cracker crumbs on top or drizzle with melted chocolate for an extra touch of elegance.
