Sort the blueberries, wash them and let them drip off on kitchen paper. Mix flour, baking powder, salt and half almonds. Mix eggs, sugar, butter and kefir briefly with the whisk of the hand mixer. Add flour mixture and stir in. Carefully fold in dry blueberries. Line the hollows of a muffin tray (12 hollows) with paper sleeves.
Spread the dough evenly in them. Sprinkle with remaining almonds. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 25-30 minutes. Leave to rest in the pan for 10 minutes. Remove the muffins from the tin and let them cool down. Whipped cream tastes good with them
