Beat the eggs, 125 g sugar and salt with the whisk of the hand mixer until foamy. Mix flour, almonds, starch and baking powder and stir into the egg mixture alternately with the milk. Spread the dough on a baking tray (32 x 39 cm) lined with baking paper. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 10 minutes. In the meantime soak the gelatine. Crumble 9 Ferrero Garden roughly.
Remove the sponge cake from the oven, turn over on a damp tea towel and carefully remove the baking paper immediately. Mix quark, sour cream, 50 g sugar and vanillin sugar. Squeeze out the gelatine, dissolve it and stir into the quark mixture drop by drop. Fold in crumbled Ferrero Garden. Cut the sponge cake in half crosswise. Cover a base with a baking frame. Pour the quark mixture onto the base and smooth it down. Place 12 Ferrero Garden evenly into the quark mixture. Pour the second cake base on top and press down a little. Chill for 2 hours. Mix icing sugar and lemon juice.
