Melt the butter. Finely crumble the rusks and mix with the butter. Place a springform pan rim (26 cm Ø) on a cake plate. Press the crumbly mixture firmly into a cake base. Put it in a cold place. Mix quark, lemon juice, diabetic sweetness and vanilla pulp until smooth. Stir in dessert powder. Whip 100 g cream until stiff. Wash lemon balm and dab dry. Pluck off leaves, chop finely and stir into the quark. Fold in the cream. Smooth the quark mixture on the sponge cake base. Chill the cake for at least 2 hours. Loosen the edge of the springform pan. Whip 150 g cream until stiff. Pour into a piping bag with star-shaped spout and squirt small tuffs onto the cake. Decorate with lime slices, lemon balm and pistachios
You can replace these ingredients:
Prepare the base with butter biscuit crumbs. Instead of the cream dessert powder for diabetics you can use 2 sachets of normal dessert sauce powder. Replace the diabetic sweetness with 100 g sugar
