Finely grate the marzipan. Beat the marzipan, soft fat and sugar until creamy with the whisk of the hand mixer. Add the eggs one after the other and stir in. Mix flour and baking powder and stir in alternately with the milk by the spoonful. Fold half of the brittle sweets into the dough.
Pour into a greased and flour-blasted box form (2 1/2 litres capacity) and smooth it down. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 45-50 minutes. If necessary, cover the cake halfway through. Remove the cake from the oven. Place on a cake rack and allow to cool for 10 minutes. Turn the cake out of the tin and let it cool completely for about 50 minutes. In the meantime, roughly chop the brittle bars and warm them up in the cream. Stir until the bars have completely dissolved (approx. 45 minutes). Coarsely chop the remaining candy.
