Toblerone chocolate fans...I got you. This Toblerone lava cake in a mug is moist, delicious and takes under 5 minutes to make because you cook the sponge in the microwave. It's perfect as a late-night snack when you have a craving for something sweet, but can't be bothered to go through the whole parade of baking a cake in the oven (and want it faster).
The idea behind a lava cake is that there is a hot pocket of melted chocolate in the middle, and Toberlone works well as you can break off a triangle and just sink it into the batter to melt whilst the sponge cooks. The honey and almond nougat also leaves little sweet crunchy bits in the sponge, it honestly is delicious. I love it served on its own but it's even more decadent with a scoop of vanilla ice cream on top.
A microwave sponge cake recipe is a great one to have up your sleeve as it can be made so quickly and you don't need a ton of measuring equipment and weighing scales, just a teaspoon, a tablespoon and a fork to mix it all together. I experimented with this Toblerone lava cake recipe for a while to get it just right, and I'm so happy with how it turned out. And reader, a lot of Toberlone chocolate was harmed in the creation of this recipe. A lot.
I make this gooey chocolate mug cake with cake mix and it's very simple, just make up the batter in a bowl with a fork, pour it into a coffee mug and sink a few chunks of Toblerone chocolate in the middle. Microwave it and voila. You get a moist sponge cake with melted Toblerone in the middle ready to be devoured.
This microwave sponge cake recipe for Toblerone lava cake was inspired by a poll I did on my Instagram, asking followers what food they looked forward to eating the most around Thanksgiving and Christmas. Someone answered Toblerone and I thought, what better than a quick microwave cake using Toblerone bar.

Substitutions and Variations
There are infinite possibilities with this mug cake recipe, here are a few.
- Chocolate - Want to change up the Toblerone? Try it with something else!
- Sugar - Try honey or maple syrup instead of granulated sugar
- Oil - this recipe also tastes great with coconut oil
You will need a small mixing bowl, a fork and a coffee mug. So easy right?! You can even mix it in the mug but I prefer to do it in a bowl to give myself more room to manoeuvre.
This microwave mug cake is best enjoyed at the time of cooking, so just make as much as you need!
This also doesn't stand up well to freezing.
You can add more Toblerone if it will fit but keep in mind that the cake mixture will expand as it cooks due to the baking powder, so be sure to leave enough room in the mug. I fill mine just over halfway before putting in the chocolate.
