Mix the flour, margarine, sugar, eggs, milk, lemon zest, crumbled yeast and raisins, knead until smooth and cover in a warm place for about 30 minutes. Then knead the dough again and roll it out on a baking sheet lined with baking paper. Let rise for another 20 minutes.
Cover the dough evenly with the butter flakes and flaked almonds. Bake in a preheated oven at 225 ° C top / bottom heat (convection: 205 ° C and gas: level 5) for about 10-12 minutes until golden.
In the meantime, stir the powdered sugar with the lemon juice until smooth. Brush the still warm cake with the lemon glaze.
