Wash, clean and halve the strawberries. Add yoghurt, icing sugar, lemon juice and zest. Finely puree everything with a hand blender. Whip the cream until stiff and allow the vanillin sugar to trickle in. Fold the cream into the yoghurt
Freeze the mixture in a mixing bowl for 3-4 hours. Stir vigorously 2-3 times in between, so that the ice cream becomes nice and creamy
Spread 8 wafers with ice cream. Place a second wafer on top of each and press down lightly. Wrap the ice cream bites individually in aluminium foil and freeze for at least 5 hours, preferably overnight.
