Mix flour and baking powder and sieve into a bowl. Add 120 g sugar, vanillin sugar, butter and 3 tablespoons of cold water. Knead first with the dough hooks of the hand mixer, then with cool hands to a smooth shortcrust pastry. Wrap dough in foil and refrigerate for 1 hour. Bring 150 g sugar and cream to the boil in a small pot. Add almonds, nuts and fruit mix and bring to the boil briefly.
Let the mixture cool down for about 20 minutes. Roll out the dough between 2 cut open freezer bags to a rectangle (30 x 40 cm). Place on a greased baking tray (30 x 40 cm) using the foil, prick several times with a fork. Pre-bake the dough in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 8 minutes. Leave to cool for 5 minutes on the baking tray. Spread the cream-fruit mixture on the pre-baked dough and smooth it down. Continue baking in the oven at the same temperature for 10-15 minutes until the surface is golden brown. Place the baking tray on a cake rack and let it cool down for 5 minutes. Cut the pastry into rectangles (3 x 7 cm) with a knife (blade coated with oil). Let the bars cool down. Chop the chocolate coating, melt with coconut oil on a hot water bath and mix. Dip the underside of the bars into the couverture, let the excess couverture drip off.
