For the Philadelphia Torte, place biscuits in a freezer bag and crumble the contents with a rolling pin or your hands. Melt the butter, mix with the crumbs and press everything into a springform pan lined with baking paper.
Mix Philadelphia, yogurt and lemon juice with an electric hand mixer. Soak gelatin in 150 ml cold water for 10 minutes. Add sugar and heat everything while stirring until gelatin and sugar are dissolved. Stir briskly into the Philadelphia cream.
Pour the Philadelphia cream onto the crumb base in the springform pan and chill the cake for at least 3 hours. Then it will be wonderfully creamy and at the same time stand and cut – so perfect all around. Before serving, decorate the Philadelphia Torte with fresh fruit as desired.
