Beat the butter and sugar until frothy. Gradually add the eggs while stirring. Add the flour, baking powder, vanilla sugar and custard powder. Gradually stir in the kefir. Finally, add a dash of mineral water so that the waffles become airy and fluffy.
Serving suggestion:
Either dust the waffles with powdered sugar or serve them on a scoop of vanilla ice cream. Cherries also taste very good with it.
Tip:
If you don`t eat the waffles right away, you should let them cool down individually so that they don`t stick to each other afterwards. You can also freeze the rest of the waffles. Bake the frozen waffles in the preheated oven at 140 ° C in the oven (fan oven 120 °) for 5-6 minutes on the wire rack.
