Wash the cherries, drain and stone them. Stir the jam until smooth and mix in the cherries, set aside. Roughly chop dark chocolate. Melt with the butter over a warm water bath. Chop white chocolate. Whisk the eggs with a whisk.
Mix flour and baking powder. Put melted chocolate in a mixing bowl. Add sugar, vanilla sugar, salt, eggs and flour mixture. Mix with the whisks of the hand mixer to a smooth dough. Fold in chopped chocolate. Grease the fat pan of the oven (32 x 39 cm) and dust with flour. Add the dough and smooth it down. Spread cherries on top. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 35-40 minutes. (Brownies are very juicy. If you don't like it, just bake the cakes a few minutes longer until no more dough sticks to the wooden skewer). Let them cool down on a cake rack.
