What is a triple chocolate mousse cake?

A triple chocolate mousse cake has three layers of chocolate mousse (milk, dark and white) set over a sponge base. Ours uses Belgian chocolate on a light cocoa sponge.

What chocolate do you use?

We use Belgian chocolate for all three mousse layers: milk, dark and white.

Is the triple chocolate mousse cake suitable for vegetarians?

No. The mousse is set with gelatine, so this cake isn't suitable for vegetarians or vegans.

How much is a triple chocolate mousse cake?

Our triple chocolate mousse cake starts at £95, with larger sizes up to £245.

What's the difference between a mousse cake and a chocolate cake?

A mousse cake is mostly set mousse on a thin sponge base, so it's lighter and silkier. A regular chocolate cake is made from layers of baked sponge.

Are your cakes suitable for people with allergies?

Our kitchen handles nuts, gluten, dairy and eggs, so we can't guarantee our products are free from traces. Please contact us before ordering if you have an allergy.
