Mix flour and baking powder. Mix eggs, milk, flour and 2 sachets of vanilla sugar to a smooth dough. Leave to swell for about 30 minutes. Sort blueberries, wash and drain. Heat some fat in a pan and pour in about 1/10 of the dough. Sprinkle about 50 g blueberries on top.
Bake the pancakes turning them golden brown. Slide onto a large plate and keep warm. Bake 9 more pancakes from the remaining dough in the same way. Put them all on top of each other on the plate and dust with icing sugar. Stir the sour cream and 1 packet of vanilla sugar until smooth and serve with the blueberry pancakes. Decorate with blueberries and lemon balm
