Chop the apricots coarsely, mix with the trail mix, sprinkle with almond liqueur and leave to stand for about 15 minutes. Mix the baking mixture, fat, eggs and milk with the whisk of the hand mixer to a smooth dough.
Fold trail mix and apricots into the dough, place on a greased baking tray, smooth down and bake in a preheated oven (electric range: 175 °C / gas: level 2) for approx. 20 minutes. Take the cake out of the oven and let it cool down.
Stir the rum glaze mixture (enclosed in the package), icing sugar and 2-3 tablespoons of water until smooth and coat the cake with it. Decorate the dried icing with brown sugar to taste.
