How to Make a Molten Chocolate Cake

This article is written by a student writer from the Spoon University at McGill chapter.

Chocolate Fondant  (a.k.a. molten lava cake or molten chocolate cake) is one of the most popular desserts during Valentine’s day. Whether you have a date to impress or you have a date with your kitchen, this cake will make your night. However, many shy away from making it at home as it requires precise timing. Just one minute too long and your cake won’t have a liquid centre, but take it out of the oven too early and the exterior of the cake will collapse. Fear not. As intimidating as this dessert may sound, here is a foolproof method to execute the perfect chocolate fondant time and time again.

9. Place a plate over the ramekin and invert the fondant onto the plate. Tap the ramekin a few times before carefully removing it.
Note: the ramekin will still be very hot at this point.

Optional: Serve with vanilla ice cream, caramel or chocolate sauce.

It’s all about timing: 

At the end of the day, mastering this recipe comes down to how long it bakes for. In the name of science, the following three chocolate fondants were baked for three different amounts of time to show how an additional minute or two affects the interior and general structure of the cake.

8 minutes: this chocolate fondant collapsed as soon as the ramekin was removed.

9 minutes: this chocolate fondant held its structure but the centre was not hot enough.

Pro tips: 

  • These fondants can be prepped ahead of time by completing up to step 6 and placing them in the fridge. Simply bring the cakes to room temperature before baking them.
  • Wrap paper towels around your tongs to help you pick up ramekins when hot.
  • Don’t have a sieve? You can use a tea infuser, it works like a mini sieve.
