For the crumble cake, preheat oven to 180 °C. Beat butter and sugar until fluffy. Gradually add eggs. Combine flour, almonds, baking powder and chocolate drops and add to the liquid mixture, mix well.
Line a baking tray with baking paper, fill in the mixture and cover with apricots. Prepare crumble by kneading butter with sugar and flour until crumble/clumps form. Spread them on the apricots.
Bake for about 45 minutes, making sure that the crumble does not get too dark – cover with aluminum foil if necessary. Let cool and dust with powdered sugar if desired.
