Clean and wash the rhubarb and cut into pieces about 1cm thick .. mix with sugar, let it steep until the sugar has dissolved, then drain the rhubarb pieces well .. I diluted the collected juice with champagne and the light cocktail Enjoyed in between..mmmhhh! I have to admit ... the recipe starts out super delicious!; O))

Mix the quark, sugar, egg, vanilla sugar and oil with the mixer to a creamy mass ... stir in half of the flour mixed with baking powder and knead in the remaining flour with your hands and roll out the quark oil dough on a greased baking sheet.

Prepare a pudding from milk, sugar and vanilla powder. Let cool a little while stirring constantly. Stir in the sour cream with a mixer and spread the pudding cream evenly on the quark oil dough.

For the crumble .. Knead sugar, flour, vanilla sugar and cold butter together and nibble from it every now and then; o)) If you use cold butter, the crumbles get bigger and I love thick butter crumbs .. mmmhhh delicious! ;O)

Spread the drained rhubarb pieces on the pudding cream and crumble the butter crumble over them. Bake at 200 ° top / bottom heat in a preheated oven for approx. 30-40 minutes ... until the desired browning is achieved. Let the rhubarb cake cool in the mold. Dust with powdered sugar and then enjoy ... mmmhhh!

WAS DELICIOUS !!!
