Cake: Juicy Plums with Butter Crumbles

For the dough, mix 250 g of wheat flour with baking powder, sieve on the work surface and make a well in the middle. Add 65 g sugar, vanilla sugar and egg and mix with part of the flour to a thick paste. Cut 125 g of cold butter into pieces and add. From the center, quickly knead all the ingredients into a smooth dough. If the dough sticks, put it in the refrigerator for a while. Roll out the dough on a greased baking sheet and sprinkle with breadcrumbs. For the topping, wash the plums, drain them well, rub dry, stone and cut the halves a little at the top. Place the plums on the dough like scales with the inside facing up. Mix 30 g sugar with cinnamon powder and sprinkle on top. Knead 120 g cold butter with 120 g wheat flour to make crumble and sprinkle over the plums. Put the baking sheet into the preheated oven and bake there at 220 degrees for about 30 to 35 minutes.
