Directions
Prepare the Base
Line the base of a 20cm (8-inch) springform cake tin with parchment.
Mix the crushed biscuits, melted butter, and cocoa powder.
Press firmly into the base of the tin using the back of a spoon.
Refrigerate while you prepare the mousse layers.
Make the Dark Chocolate Mousse Layer
Melt the Whitakers dark chocolate gently over a pan of simmering water or in the microwave in short bursts. Let cool slightly.
In a separate bowl, whip the double cream, icing sugar, and vanilla until soft-medium peaks.
Fold the melted chocolate into the whipped cream until smooth and fully combined.
Spoon over the biscuit base and level the top.
Chill in the fridge for 30 minutes before adding the next layer.
Make the Milk Chocolate Mousse Layer
Melt the Whitakers milk chocolate and allow to cool slightly.
Whip the double cream and icing sugar to soft-medium peaks.
Fold in the melted chocolate.
Carefully spoon over the dark chocolate layer.
Chill for another 30 minutes.
Make the White Chocolate Mousse Layer
Melt the Whitakers white chocolate and allow to cool slightly.
Whip the double cream and icing sugar.
Fold in the melted chocolate until smooth.
Gently spread over the milk chocolate mousse layer.
Chill the Cake
Refrigerate the entire cake for at least 4–6 hours, or overnight for best results.
Remove from the tin and slice with a hot knife for clean layers.

If you want cleaner, sharper layers, freeze the cake for 20 minutes between layers.
For a lighter option, replace one-third of the cream with Greek yoghurt (this makes the mousse slightly tangier and softer).
For a richer chocolate flavour, add 1 tsp espresso powder to the dark chocolate mousse.
Decorate the top with shaved Whitakers chocolate, cocoa dusting, or fresh berries.

A Brief History of Mousse in the UK
Mousse started in France during the 18th century as savoury dishes, often served at fancy events.
These early versions used whipped egg whites to create a light, foamy texture.
By the late 19th century, sweet mousses became common, with chocolate mousse appearing in recipes around that time.
In the UK, chocolate mousse grew popular from the 1960s, as French cooking styles spread to homes and restaurants.
It featured in cookbooks, TV shows, and magazines during the 1970s and 1980s.
People saw it as an elegant option for dinner parties, often made at home or bought ready from supermarkets in packets like Angel Delight or frozen tubs.
Over time, it linked to 1980s nostalgia, even appearing in British comedy sketches.
Today, mousse remains a classic in UK desserts, especially chocolate types, and fits into broader British pudding traditions that mix creamy textures with simple prep.
