120 ml (4 fl oz or 1/2 cup) milk
15 ml (1 tbsp) rum or vanilla essence
115 gr (4 oz or 1/2 cup) unsalted butter, softened
175 gr (6 oz or 3/4 cup) granulated sugar
3 eggs
225 gr (8 oz or 2 cups) plain flour
10 ml (2 tsp) baking powder
pinch of salt
675 gr (1 ½ lb) fresh strawberries, sliced, plus extra for decoration
750 ml (1 1/4 pints or 3 cups) whipping cream
30 ml (2 tbsp) rum or strawberry-flavoured liqueur

White chocolate mousse filling
250 gr (9 oz) white chocolate, chopped into small pieces
350 ml (12 fl oz or 1 1/2 cups) double cream
30 ml (2 tbsp) rum or strawberry-flavoured liqueur


Grease and flour two 23 x 5 cm/9 x 2 in cake tins. Line the base of the tins with non-stick baking paper.

Preheat oven to 180º C 

Make the cake.

Melt the chocolate and cream in a double boiler over a low heat, stirring until smooth.

Stir in the milk and rum or vanilla essence, and set aside to cool.

In a large mixing bowl, beat the butter and sugar with a hand-held electric mixer for 3-5 minutes, until light and creamy, scraping the sides of the bowl occasionally.

Add the eggs one at a time, beating well after each addition.

In a small bowl, stir together the flour, baking powder and salt.

Alternately add flour and melted chocolate to the egg mixture in batches, until just blended. Pour the mixture into the tins and spread evenly.

Bake for 20-25 minutes, until a skewer inserted in the cake comes out clean. Cool in the tin for 10 minutes, then turn cakes out on to a wire rack, peel off the paper and cool completely.

Make  the mousse.

In a medium saucepan over a low heat, melt the chocolate and cream until smooth, stirring frequently. Stir in the rum or strawberry-flavoured liqueur and pour into a bowl. Chill until just set. With a wire whisk, whip lightly.


Assembling the cake.

With a serrated knife, slice both cake layers in half, making four layers.

Place one layer on the plate and spread one third of the mousse on top. Arrange one third of the sliced strawberries over the mousse. Place the second layer on top and spread with another third of the mousse. Arrange another third of the sliced strawberries over the mousse.Place the third layer on top and spread with the remaining mousse. Cover with the remaining sliced strawberries. Top with the last cake layer.

Whip the cream with the rum or liqueur until firm peaks form. Spread about half the whipped cream over the top and the sides of the cake.

Spoon the remaining cream into a decorating bag fitted with a medium star tip and pipe scrolls on top of the cake. Decorate with the remaining sliced strawberries, pressing half of them into the cream on the side of the cake and arranging the rest on top.


The strawberries can be substituted for any other seasonal fruit; play around with the liqueur as well, giving this juicy cake your personal touch!
