Ingredients

Why this recipe works

The method relies on a high ratio of chocolate and butter to flour, which creates a batter that sets on the outside while remaining soft and molten in the center.

The brief, hot bake at 400°F (200°C) cooks the edges quickly, forming a delicate crust, while the center stays gooey. The addition of egg yolks adds richness and helps the batter hold its shape without becoming too firm.

The hidden dollop of chocolate hazelnut spread amplifies the molten factor, creating a distinct, intensely flavored lava that flows out when the cake is broken.

Baking in a mini cast iron skillet provides excellent heat retention, which helps achieve the perfect contrast between the crisp exterior and the soft interior. The skillet also makes for a beautiful, rustic presentation that is perfect for serving straight from the oven.

Notes and substitutions

Use high-quality dark chocolate (60-70% cacao) for the best flavor and meltability. Chop it finely so it melts evenly. Unsalted butter is preferred to control the salt level; if using salted, reduce the flaky sea salt topping. The eggs and egg yolks should be at room temperature to incorporate smoothly into the batter.

Mini cast iron skillets (about 5 inches) are ideal for this recipe, but you can also use ramekins or oven-safe mugs. If using ramekins, adjust the baking time slightly, as they may cook faster. The chocolate hazelnut spread should be thick; if it is too runny, chill it for 10 minutes before spooning into the batter.

• dark chocolate: Use semi-sweet or bittersweet chocolate (60-70% cacao) for a less sweet result. Milk chocolate will make the cake sweeter and softer.
• chocolate hazelnut spread: Any chocolate-hazelnut spread works. For a different flavor, try a chocolate-caramel spread or a peanut butter-chocolate spread, but note the texture may vary.
• vanilla bean ice cream: Substitute with any premium vanilla ice cream or a dairy-free vanilla alternative. The cold contrast is key, so choose a firm scoop.
• unsalted butter: Salted butter can be used; omit the flaky sea salt topping or reduce it slightly to balance the salt.
