This super-rich 'Matilda chocolate cake' is just like the cake in Roald Dahl's classic tale - and we think it's just perfect for a birthday.

Layers of soft sponge are sandwiched together by creamy chocolate frosting, and the cake is topped with our favourite chocolates - Crunchie bars and Maltesers. And, unlike our classic chocolate cake, there's popping candy in every layer - what a treat. This cake only takes an hour and a half to make, including prep and baking time which makes it a pretty speedy bake for an indulgent chocolate cake, so you can make it even if you're not the most confident of bakers.
