Pour the cherries into a sieve, drain well and collect the liquid. Fill up the cherry juice with water to 400 ml. Boil up in a pot. In the meantime stir sauce powder, 3-4 tablespoons of water and 25 g sugar until smooth.
Stir into the boiling liquid and simmer for about 1 minute while stirring. Carefully mix in the cherries. Pour the compote into a bowl and let it cool down. In the meantime, for the waffle dough, whip the fat, 50 g sugar, vanillin sugar and salt until creamy with the whisks of the hand mixer.
Stir in the eggs one by one. Mix flour, baking powder and seasoning and stir in alternately with 100 ml milk and cream. Put approx. 1 1/2 tablespoons of dough in the middle of a greased preheated waffle iron and bake until golden brown.
From the remaining dough bake another 7 waffles in the same way. Mix quark, 3 tablespoons of milk and 2 tablespoons of sugar until the sugar crystals have dissolved. Separate the waffles into heart shape as desired, dust with icing sugar.
Add a little cherry compote and quark cream and sprinkle with egg liqueur. Decorate with mint.
