Coarsely chop candies with a sharp knife. Beat the fat, sugar and salt with the whisk of the hand mixer until foamy. Stir in eggs one after the other. Add egg liqueur, continue stirring until the sugar is completely dissolved. Mix flour and baking powder, sieve onto the egg-fat mixture and stir in. Fold in sweets.
Pour the dough into a greased, breadcrumbed ring cake mould (2.5 litres capacity). Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 60-65 minutes. Take the cake out of the oven and let it cool down on a cake rack for about 10 minutes. Turn out of the tin and let it cool down. Dust with icing sugar
