How to make
Beat the eggs with a mixer until you get a snowy mix. In a thin trickle, add the flour, baking powder and vanilla.
Beat until homogeneous, then transfer the mixture to an oven dish with a nonstick coating. Bake 20 min. at 360°F (180 °C) without the fan. In the meantime, make the cream.
Beat the yoghurt with the powdered sugar, juice and grated rind of the orange. Pour this mixture over the baked and cooled cake layer. Leave the cake overnight in the fridge.
