Why This S’mores Swiss Roll Works So Well

Traditional s’mores rely on contrast: crisp graham crackers, melted chocolate, and toasted marshmallows. Translating that into cake form means respecting those textures while adapting them into something sliceable, elegant, and shareable.

Here’s how this recipe nails it:

• Chocolate sponge cake stays flexible, preventing cracks when rolling
• Marshmallow filling melts slightly into the cake, creating that iconic pull
• Graham cracker flavor adds subtle crunch and nostalgia
• Chocolate drizzle or ganache deepens the cocoa richness

The result? A dessert that tastes like summer nights by the fire—without needing a campfire at all.

Instructions

1. Prepare the Pan
   Preheat your oven to 350°F (175°C). Line a rimmed baking sheet with parchment paper and lightly grease.
2. Make the Chocolate Batter
   Whisk together flour, cocoa powder, baking powder, and salt. In a separate bowl, beat eggs and sugar until thick and pale. Mix in vanilla, milk, and melted butter.
3. Combine & Bake
   Gently fold dry ingredients into wet ingredients until just combined. Spread batter evenly into the prepared pan and bake for 10–12 minutes until set but soft.
4. Roll While Warm
   Turn the warm cake onto a clean towel dusted with powdered sugar. Peel off parchment and gently roll the cake (with towel) from the short side. Let cool completely.
5. Prepare Marshmallow Filling
   Beat butter until creamy. Add powdered sugar and vanilla, then fold in marshmallow fluff until light and spreadable.
6. Fill & Roll
   Carefully unroll the cooled cake, spread marshmallow filling evenly, sprinkle with graham cracker crumbs, then re-roll tightly.
7. Finish with Chocolate
   Melt chocolate with cream to create a drizzle or ganache. Pour over the roll and let set before slicing.
