Heat the butter and sugar in the pan. Add the oatmeal and roast until golden brown. Pour onto a plate to cool. Beat the cream with the mixer until stiff. Then add the quark, sugar, lemon juice and stir with the cream. Drain the cherries and pour them into a glass bowl. Pour half of the oat flakes over the cherries, then pour the curd and cream cream on top and top with the remaining oat flakes.
Alternatively, instead of a glass bowl, you can also prepare 4 individual portions in champagne bowls or something similar.
