Chef Tips
Add the chocolate to the eggs slowly
The melted chocolate and butter mixture is hot, the eggs are raw. Pour the chocolate into the eggs in a steady stream while folding constantly to temper it in. Tipping it all in at once will scramble the yolks and you’ll end up with sweet chocolate omelette instead of a glossy batter.
Coat the ramekins with cocoa
After greasing the ramekins with soft butter, dust the insides with cocoa powder and tap out the excess. The cocoa gives the cake an extra layer of bittersweet crust on the outside and helps it release cleanly from the ramekin. Bonus: it looks better than flour or sugar.
Make them ahead
You can portion the batter into greased ramekins, cover with cling film and chill overnight. Bake straight from the fridge, just add 2 minutes to the cook time (9 to 10 minutes total). This is the move when you’ve got people coming for dinner and want a fancy dessert without the last-minute pressure.
Don’t open the oven door early
The cakes set quickly and a sudden temperature drop can cause them to deflate. Trust the timer for the first bake (7 to 8 minutes for fresh batter) and only check at the end. The top should look just set and slightly cracked at the edges.
Storage
These are best eaten the moment they come out of the oven. The whole point is the molten centre, which sets up firmer the longer you leave them. Unbaked batter in greased ramekins keeps in the fridge for up to 2 days, covered with cling film, and is honestly the best way to plan this dessert ahead. If you do end up with leftover baked cakes, they’ll keep at room temperature for a few hours but the centre will be set to a regular chocolate cake texture by then.
FAQs
Why is the centre fully cooked through? You’ve baked them a minute too long. The window between molten centre and fully set is tight, and it varies a bit depending on your ramekins and oven. Pull them out the second the top looks just set, the residual heat keeps cooking for another minute or two while they sit before inverting.
Can I make these gluten-free? Yes, swap the plain flour for a 1:1 gluten-free baking flour blend and it works almost identically. The recipe only uses 35g of flour so the texture isn’t heavily dependent on gluten.
What size ramekins should I use? 200ml capacity is the sweet spot. Smaller and the centre cooks through before the outside sets, larger and the cake collapses under its own weight when you invert it. If you only have 150ml ramekins, reduce the bake time to 5 to 6 minutes and check earlier.
