Prepare the sponge cake batter for schnitten according to the basic recipe, and bake two cake bases.
Brush one cake base with warmed apricot marmalade.
Place a baking frame around this cake (or place in a deep cake pan).
Mix the quark, mascarpone or sour cream, confectioner’s sugar, rum, lemon zest, vanilla sugar, and raisins in a mixing bowl.
Warm the orange juice.
Add cold water to the gelatin, remove excess water, dissolve in orange juice, and stir into the quark mixture.
Now mix in the apricot marmalade.
Finally, fold the whipped cream and apricots into the quark cream and fill the pan.
Place the second cake on top and chill for 4 hours.
Cut with a serrated knife dipped in hot water and dust each piece with confectioner’s sugar.
