Cream 125 g butter, 125 g sugar and salt with the whisk of the hand mixer. Stir in the eggs one by one. Mix 150 g flour, ground hazelnuts and baking powder. Alternately stir in with the milk.
Fold in the chocolate flakes. Grease 12 troughs of a muffin tray and dust with flour. Fill the dough evenly into the hollows. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 20 minutes.
In the meantime, bring whipped cream, 2 tablespoons of water, 100 g sugar, vanillin sugar and 50 g butter to the boil. Reduce over low heat in an open pot for about 6 minutes. Roughly chop the cherries. Stir in cherries, hazelnut and almond flakes and 65 g flour.
Remove the muffins from the oven and quickly cover with the Florentine mixture. Bake the muffins at the same heat for 12-15 minutes. Remove them from the muffins, remove them from the baking trays after 10 minutes and let them cool down on a cake rack.
