Ingredients

3/4 cup butter, softened
6 None eggs, separated
3/4 cup sugar
7 oz marzipan, grated
2 tsp vanilla extract
1 cup all-purpose flour, plus extra to dust pan
2/3 cup whole wheat flour
1 1/2 tsp baking powder
1 cup ground almonds
3.5 oz dark baking chocolate, broken into pieces
2 tbsp cocoa powder
3 tbsp rum
2 tbsp almond liqueur (such as amaretto)
1 tbsp flaked almonds
10.5 oz dark chocolate (70% cocoa solids), broken into pieces
8 oz white chocolate, broken into pieces

Preparation

Preheat the oven to 325\u00b0F. Grease a 10 1/2 cup Bundt pan and sprinkle with flour. Beat the butter until creamy. Stir in the egg yolks and 1/2 cup sugar. Add the marzipan and vanilla extract and mix.
In a separate bowl, beat the egg whites and a pinch of salt until stiff peaks form, then gradually add 1/4 cup sugar. Using a wooden spoon, stir in the flours, baking powder and ground almonds. Add this mixture to the marzipan mixture, stirring just until combined.
Melt the baking chocolate in a heatproof bowl set over a pan of simmering water. Spoon one-third of the cake batter into a bowl and, using a wooden spoon, stir in the melted chocolate, cocoa, rum and almond liqueur.
Spoon half the plain batter into the pan, then spoon in the chocolate batter, then the remaining plain batter. Swirl with a fork to form a marbled effect. Sprinkle with the flaked almonds. Bake for 45-50 mins, until a skewer comes out clean. Allow to cool for 30 mins, then turn out of the pan on to a wire rack and allow to cool completely.
Melt the dark chocolate in a heatproof bowl set over a pan of simmering water. Spread over the cake. Allow to set.
Melt the white chocolate in the same way. Spoon white chocolate over the cake, allowing the chocolate to drizzle down the sides. Allow to set.
