Hot Chocolate Lava Cake: Molten Chocolate Layers
This French hot chocolate lava cake is a rich dessert consisting of a firm outer sponge and a liquid core. It balances the bitterness of 70% cocoa dark chocolate with a smooth, buttery texture. You serve it warm to ensure the molten centre remains fluid upon slicing.
The success of this cake depends on the temperature and the mixing process. Use an instant-read thermometer to ensure the centre reaches 88–90°C (190°F). If the heat is too high, the cake will bake through and lose its liquid core. Gently fold in the flour to minimise bubbles, which keeps the centre silky and free of cracks. Allow the batter to rest at room temperature for 10 minutes before baking. This step ensures even heat distribution and a smoother rise across the cakes.

Recipe cardIngredients
Instructions
-
Prepare the ramekins
Preheat your oven to 160°C (325°F). Grease each ramekin with a thin layer of butter and dust them with cocoa powder. Tap out the excess powder to ensure the cakes release cleanly from the sides.
-
Melt the chocolate
Melt the dark chocolate and 75°g of butter together using a double boiler or a microwave in 20-second bursts. Stir until the mixture is completely smooth and glossy. This prevents the chocolate from seizing or burning.
-
Whisk the eggs
In a separate bowl, whisk the eggs, yolks, caster sugar, vanilla, and sea salt. Continue for about 1 minute until the mixture is pale and aerated. This aeration provides the necessary lift for the cake.
-
Combine the mixtures
Fold the melted chocolate mixture into the egg mixture until just combined. Sift the flour over the batter and fold gently with a spatula until the dough is uniform. Avoid over-mixing to keep the texture light.
-
Prepare for baking
Divide the batter evenly among your greased ramekins, filling each to about three-quarters full. Let the batter rest at room temperature for 10 minutes. This ensures even heat distribution and a smoother rise.
-
Bake in water bath
Place ramekins in a baking tin and pour hot water until it reaches halfway up the sides. Bake for 12–13 minutes until the edges are set but the centre remains soft. The water bath prevents the edges from overcooking.
-
Cool and serve
Remove the tin from the oven and let the cakes sit for 2 minutes. Carefully invert each cake onto a plate. Use a thermometer to ensure the centre reads 88–90°C (190°F) for a molten consistency.
Check the centre temperature with an instant-read thermometer. If the centre exceeds 90°C (190°F), the lava will solidify into a standard sponge. Fold in the flour gently to minimise bubbles, which keeps the molten centre silky and free of cracks.
Getting the texture right
Fold in the flour gently to minimise bubbles. This keeps the molten centre silky and prevents cracks. Let the batter rest at room temperature for 10 minutes before baking to ensure even heat distribution and a smoother rise. Use a thermometer to hit 88–90°C (190°F) in the centre.
Storing and reheating
Wrap individual cakes in plastic film and place them in an airtight container. Store in the freezer for up to 3 months. To serve, thaw in the fridge overnight. Re-warm in a 90°C (190°F) oven for 5 minutes to restore the molten state without overcooking the edges.

Questions people ask
What is the difference between molten cake and lava cake?
Lava cakes traditionally have a liquid centre created by underbaking the batter. Molten cakes often use a frozen ganache core to ensure a consistent flow of chocolate regardless of the exact bake time.
What type of chocolate is best for melting in lava cakes?
Use dark chocolate with at least 70% cocoa. High cocoa content provides a stable structure for the cake walls while ensuring the centre remains rich and intensely savoury rather than overly sweet.
How do you make hot lava cake?
Melt chocolate and butter, then fold into aerated eggs and sugar. Sift in flour and bake in a water bath at 160°C (325°F) for 12–13 minutes until the edges set but the centre stays soft.
