For the almond whipped cream slices, whip all ingredients strongly with a mixer for about 5 minutes. Pour the batter into a greased springform pan (square or round).
Bake at 180 °C top/bottom heat for about 45 minutes.
For the cream, whip the cream with the powdered sugar until stiff, then mix in the almonds. Place a springform ring around the cake and spread a thin layer of jam on the bottom.
Spread the cream on top and refrigerate the almond whipped cream slices for about 3 hours. Then decorate as desired.
