Line the recesses of a muffin tray (for 12 pieces) with paper baking cups. Sort blueberries, wash and pat dry. Mix flour, baking powder, 1 pinch of salt and almonds. Mix kefir, butter, eggs and sugar briefly with the whisk of the mixer.
Stir in the flour mixture briefly.
Fold blueberries into the dough. Spread the dough into the hollows. Bake in the preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer) for 20-25 minutes. Let cool off. Whipped cream tastes good with it.
