Chop nuts. Dice plums. Cream soft fat and diabetic sweetness. Stir in egg and milk. Mix flour and baking powder and stir in. Fold plums and 2/3 nuts into the dough
Place 2-3 paper forms into each other. Fill 2/3 each with dough. Bake in the preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3) for 35-40 minutes. Let them cool down
Heat the jam and spread it on the muffin surface. Sprinkle muffins with the remaining nuts
-If you have a microwave oven, you can heat up the jam in a suitable bowl in a flash
-Muffins keep fresh for about 2 days when wrapped in aluminium foil. Or they can be frozen and thawed as required, e.g. for a spontaneous coffee party. Bake briefly if necessary
