For the dough, beat the sugar, margarine and egg until frothy. Mix in the flour, baking powder, almonds and cinnamon powder.
Spread the dough on a baking sheet lined with baking paper, cover generously with peeled apples cut into strips.
For the crumble: knead the margarine, flour, sugar, cinnamon powder and vanilla sugar into crumble and spread on the cake. If you like the streusel particularly sweet, you can also mix a few drops of liquid sweetener with the dough.
Put it in the oven for 35 minutes at 160 ° C, middle rail. Enjoy your meal 🙂
