For the base, beat the eggs with powdered sugar and vanilla sugar until frothy, then fold in the oil, yogurt, grated poppy seeds, flour, and baking powder. Spread the batter on a baking sheet lined with non-stick paper (for a 60 cm oven) and bake at 175°C for about 35 minutes, then let it cool.
For the cream, mix the yogurt, quark, powdered sugar, lemon juice, and vanilla sugar. Soak 4 sheets of gelatin and dissolve them in some warmed rum. Whip the cream and fold it in. Spread the cream over the poppy seed base and refrigerate for 1 hour.
For the raspberry glaze, briefly cook the raspberries and puree them with powdered sugar. Mix 3 sheets of gelatin with the raspberry puree. Pour and spread it over the chilled quark mixture. Chill in the refrigerator for about 1 hour more (preferably overnight).
For decoration, place small dollops of whipped cream on each piece of cake and garnish with a raspberry.
