This red velvet lava cake is six individual chocolate cakes with a molten centre — deep red on the outside, warm and flowing in the middle. The batter takes about 15 minutes to put together, then it chills for an hour before a short bake. That chilling window is exactly what makes these practical: you can prep them hours ahead and bake to order.
The short version of why this works
Two things actually matter here. First, the batter is chilled before baking — this slows the heat from reaching the centre, so the outside sets into a thin cake shell while the middle stays liquid. Skip the chill and you get a fully baked cake, not a lava cake. Second, the ratio of chocolate to flour is deliberately high and the flour is cake flour, which has less protein than all-purpose. That keeps the shell tender enough to give way cleanly when you cut in, rather than turning rubbery or dense around the edges.
Ingredient notes
- Semi-sweet baking chocolate: Use a bar, not chips. Chips contain stabilisers that prevent smooth melting and can make the centre grainy rather than fluid.
- Cake flour: All-purpose flour will work in a pinch, but the shell will be slightly tougher. If you substitute, use 2 tablespoons less per half cup.
- Red food colouring: Gel colouring gives a vivid, saturated red without adding extra liquid. If you use liquid colouring, you may need closer to 1 teaspoon and the colour will be slightly less intense. Either works — the flavour is identical.
- Ramekin size: Use 6-oz ramekins. A 4-oz ramekin will overflow; an 8-oz ramekin will underfill and the bake time will be off. Standard 6-oz is the right fit for this batter yield.
Mistakes to avoid
- Not greasing the ramekins properly: Butter the inside of each ramekin thoroughly, then dust with cocoa powder (not flour — flour leaves a pale coating that shows on the outside of the cake). Tap out the excess. This is what lets the cake release cleanly.
- Overheating the chocolate: Melt the chocolate and butter over barely simmering water, not boiling. If the water is too hot, the chocolate can seize or the butter can separate. Stir gently and pull the bowl off the heat as soon as it is smooth.
- Skipping the knife step before unmoulding: Run a thin knife or offset spatula around the inside edge of each ramekin before inverting. Even well-greased ramekins can stick at one spot. A quick pass takes three seconds and prevents a broken cake.
- Overbaking: The cakes are done when the edges are set and the very centre of the top still looks slightly underdone — it should not jiggle like liquid, but it should not look fully matte either. If the top looks completely set and dry, the centre has already baked through. Pull them at 14 minutes and check; every oven runs differently.
- Forgetting the salt: The recipe card ingredient list includes a pinch of salt — add it when you combine the dry ingredients. It is a small amount but it sharpens the chocolate flavour noticeably.
Keeping and reheating
Unbaked, filled ramekins keep in the fridge for up to 24 hours, tightly covered — this is the most useful thing about this recipe. You can prep a full batch of six, bake two for dinner, and keep the rest ready to bake on demand over the next day. Once baked, lava cakes do not reheat well; the centre firms up and you lose the molten effect entirely. If you have leftover baked cakes, eat them at room temperature — they become a dense, fudgy individual chocolate cake, which is honestly not a bad outcome. Skip the confectioners sugar garnish on any you are storing; it dissolves within minutes and adds nothing once the cake has cooled.
Red Velvet Lava Cake with Molten Chocolate Centre
Equipment
- Ramekins
- Sieve
- Heatproof Bowl
Ingredients
- 7 tablespoons unsalted butter cut into pieces
- 1¼ cups semi-sweet baking chocolate chopped
- 2 large eggs
- 3 large egg yolks
- ½ cup cake flour
- ½ cup confectioners' sugar plus extra for dusting
- 1 pinch salt
- ½ teaspoon gel red food colouring or 1 teaspoon liquid red food colouring
Instructions
- Melt the chocolate and butter together in a heatproof bowl set over a saucepan of barely simmering water (double boiler method), stirring occasionally until smooth. Alternatively, microwave in 30-second bursts, stirring between each, until fully melted. Remove from heat and let cool for 5 minutes.
- Add the eggs and egg yolks and whisk well to combine and smooth.
- Sift the cake flour, salt, and confectioners' sugar through a fine-mesh sieve into the chocolate mixture. Add the red food colouring and whisk gently until the batter is smooth and evenly coloured. Do not overmix.
- Cover the bowl with plastic wrap and refrigerate for 1 hour until the batter is firm enough to hold its shape. While the batter chills, thoroughly grease six 6-oz ramekins with butter and dust with cocoa powder, tapping out the excess. This ensures the lava cakes release cleanly.
- Divide the batter evenly among the prepared ramekins, filling each about three-quarters full. Place on a baking sheet and bake in a preheated oven at 375°F / 190°C (170°C fan-forced) for 14–16 minutes, until the edges are set and firm but the centre still jiggles slightly when gently shaken.
- Let the ramekins rest for 30 seconds, then run a thin knife around the inside edge of each ramekin. Invert onto a serving plate, give a gentle tap, and carefully lift the ramekin away. Dust with confectioners' sugar and serve immediately while the centre is still molten.

FAQ
Can I make these ahead of time?
Yes — assembled, unbaked ramekins keep in the fridge for up to 24 hours before baking. Cover each one with plastic wrap and bake straight from the fridge; you may need to add one to two minutes to the bake time since the batter will be colder than if it had only chilled for the minimum 60 minutes.
How do I know when lava cakes are done without cutting one open?
The edges should look fully set and pulling slightly away from the sides of the ramekin, while the centre of the top still has a subtle soft spot — not wet, but not completely matte and firm. If you are unsure, sacrifice one cake from the batch as a test before pulling the rest.
Can I freeze the unbaked batter in the ramekins?
Yes, for up to one month. Wrap each filled ramekin tightly in two layers of plastic wrap and freeze. Thaw overnight in the fridge before baking, and add two to three minutes to the bake time. Do not bake from frozen — the outside will overcook before the centre thaws.
