What is S’mores Lava Cake?
S’mores Lava Cake is a unique twist on the traditional lava cake. Instead of just the molten chocolate center, you get an extra layer of gooey marshmallow in the middle, reminiscent of the classic s’mores treat. When baked, the cake has a rich, fudgy texture on the outside, while the inside remains molten with a perfect blend of chocolate and marshmallow. The graham cracker crumbs sprinkled on top add the finishing touch, giving it the crunchy element that makes s’mores so iconic. This dessert is indulgent and comforting, offering a warm, gooey center that’s the perfect combination of sweet and rich.
The Origin of S’mores Lava Cake
The traditional s’mores treat originated in the United States in the early 20th century, especially popular in camping settings. The simple, yet beloved treat of roasted marshmallows, chocolate, and graham crackers has become a symbol of outdoor fun and cozy nights by the fire. The idea of adding this familiar combination to a molten lava cake emerged as a modern twist on a classic dessert. Lava cakes, which are also known as molten chocolate cakes, gained popularity in the 1980s when chef Jean-Georges Vongerichten famously introduced the dish at his New York City restaurant. By merging these two ideas, the s’mores lava cake has become a decadent and indulgent way to enjoy the nostalgic flavors of s’mores in a more sophisticated form.
Ingredients for S’mores Lava Cake
For the Cakes:
- ½ cup (115 g) unsalted butter
- 6 oz (170 g) semi-sweet chocolate, chopped
- 2 large eggs
- 2 large egg yolks
- ¼ cup (50 g) granulated sugar
- 1 tsp vanilla extract
- ¼ cup (30 g) all-purpose flour
- Pinch of salt
Filling:
- 4 large marshmallows (or ½ cup mini marshmallows)
For Serving:
- Crushed graham crackers
- Chocolate syrup or melted chocolate
- Optional: extra toasted marshmallows or ice cream
Step-by-Step Instructions for S’mores Lava Cake

Preheat & Prep:
- Start by preheating your oven to 425°F (220°C).
- Grease 4 ramekins (6 oz size) with butter and dust them lightly with either cocoa powder or crushed graham crackers. This ensures that the cakes don’t stick to the sides and adds flavor.
Melt Chocolate & Butter:
- In a heatproof bowl, combine the unsalted butter and semi-sweet chocolate. You can melt them together in the microwave in 20-second bursts, stirring in between, or use a double boiler for a gentler method.
- Stir until the mixture is smooth and fully melted, then set it aside to cool slightly.
Make the Cake Batter:
- In another large bowl, whisk together the eggs, egg yolks, granulated sugar, and vanilla extract. Whisk until the mixture becomes thick and pale, about 2 minutes.
- Once the chocolate-butter mixture has cooled slightly, gently stir it into the egg mixture.
- Fold in the all-purpose flour and salt, mixing just until combined. Be careful not to overmix, as this could affect the texture of the cakes.
Assemble the Cakes:
- Spoon half of the cake batter evenly into the prepared ramekins, filling them about halfway.
- Place one large marshmallow (or a few mini marshmallows) in the center of each ramekin.
- Cover the marshmallow with the remaining batter, ensuring each ramekin is filled about ¾ full.
Bake the Lava Cakes:
- Bake the cakes in the preheated oven for 12-14 minutes, or until the edges are set, but the centers are still slightly soft. This will ensure that the molten chocolate and marshmallow center remains gooey and indulgent.
Cool & Serve:
- Let the cakes cool for about 1 minute before carefully inverting them onto plates. Be gentle, as the cakes are delicate.
- Serve immediately with a sprinkle of crushed graham crackers on top, drizzled with chocolate syrup or melted chocolate, and, if you wish, extra toasted marshmallows or a scoop of ice cream for added indulgence.
Variations of S’mores Lava Cake
While the classic S’mores Lava Cake is absolutely delicious, there are plenty of ways to mix things up and tailor it to your taste preferences:
- Add Espresso: For a deeper, richer chocolate flavor, add a tablespoon of espresso powder to the batter. It enhances the chocolate’s intensity without overpowering the dessert’s sweetness.
- Use Different Marshmallows: If you prefer a more authentic s’mores flavor, use mini marshmallows instead of large ones. This will give you more gooey goodness in the center.
- Caramelized Marshmallows: For an extra toasted flavor, try caramelizing the marshmallows before adding them to the center. You can do this with a kitchen torch or by placing them under the broiler for a few seconds.
- Nutty Twist: Add chopped nuts, like walnuts or pecans, to the batter for a crunchy contrast to the soft, gooey texture.
- Vegan or Gluten-Free Options: Replace the eggs with a flaxseed mixture, the butter with a dairy-free alternative, and the flour with a gluten-free variety to make this dessert suitable for those with dietary restrictions.
Frequently Asked Questions (FAQs) about S’mores Lava Cake
1. Can I make the batter ahead of time?
Yes! You can prepare the batter ahead of time and store it in the refrigerator. Just bring the batter to room temperature before baking it. This makes it a great dessert to prepare in advance for a dinner party or special occasion.
2. What if I don’t have ramekins?
If you don’t have ramekins, you can use oven-safe cups or muffin tins. Just make sure they are well-greased, and keep in mind that the baking time may vary depending on the size of the containers.

Yes, you can freeze the cakes before baking them. Assemble the cakes in the ramekins, cover tightly with plastic wrap or foil, and freeze for up to 2 months. When you’re ready to bake, just pop them into the preheated oven and bake as usual, adding a few extra minutes if needed.
4. Can I use other chocolate types?
Absolutely! You can use milk chocolate or dark chocolate if you prefer a sweeter or more intense flavor. Just keep in mind that it will affect the overall taste of the lava cake.
5. What should I serve with S’mores Lava Cake?
S’mores Lava Cakes are delicious on their own, but you can elevate them by serving them with vanilla ice cream, whipped cream, or extra marshmallows toasted to perfection. The choice is yours!
