Drain the apricots. Cream fat, diabetic sweetener, vanilla pulp and salt with the whisk of the hand mixer. Stir in the eggs one by one. Mix almonds, flour and baking powder and stir in portions alternately with the milk. Spread the dough into a greased fat pan (approx. 32 x 38 cm).
Spread apricots and rhubarb on top. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 ° C/ gas: level 2) for approx. 1 1/4 hours. If necessary, cover with aluminium foil in the last minutes. Let them cool down
