Stir soft fat until foamy. Stir in 150 g diabetic sweetener. Beat in the eggs bit by bit. Mix flour and baking powder. Stir in sour cream by the spoonful and work into a smooth dough. Grease a fat pan of the oven (approx. 38 x 32 cm) and spread the dough on it. Bake in a preheated oven at 225 °C (fan oven: 200 °C) for about 20 minutes. Melt the butter. Add remaining diabetic sweetener and cream and bring to the boil while stirring. Fold in flaked almonds and simmer for about 3 minutes. Spread almond butter mixture on the cake and bake for another 5-10 minutes at the same temperature
