Preheat the oven to 160 degrees, gas between level 2 and 3. Line the muffin tray with paper baking cases. If there is no muffin tin, always put 2 paper cases inside each other and place on a baking sheet.
Shape the marzipan mixture into 12 balls of the same size and dust with flour.
Mix the dry ingredients flour, baking powder, baking soda with a spoon. Mix the moist ingredients of egg, sugar, oil, buttermilk or yoghurt, poppy seeds and a pinch of salt with a whisk.
Briefly stir the dry ingredients into the wet ingredients with a fork. Large pieces of flour can remain, it should not be stirred for too long and under no circumstances with an electric stirrer, as otherwise the mass becomes rock-hard when baking.
Pour half of the dough into the molds, press a marzipan ball on top, and pour the rest of the dough over it. Bake for 20-25 minutes.
Tip:
Muffins are very easy to freeze. Simply place in the oven or microwave briefly to defrost.
