No-Bake Butter Cookie Cake with Vanilla Cream!

In a bowl, mix the quark with the powdered sugar and vanilla sugar. In another bowl, whip the cream with the powdered sugar until stiff peaks form. In a third bowl, whisk the milk with the Galetta cream powder and vanilla sugar.
Then mix everything together and divide the mixture in half.

Line a small, deep baking sheet or dish (26x20cm) with parchment paper (I recommend crumpling the parchment paper and soaking it in water, wringing it out, and then lining the dish with it. It works so much better). Spread the cookies on the bottom of the dish, drizzle with milk, spread with half of the filling, then cover with more cookies, drizzle with milk, and spread the rest of the filling on top. Finally, create a layer of cookies.
Brush with milk and refrigerate overnight.
