Pour 2 tablespoon of the batter into each muffin pan.
Bake in the preheated oven at 180 ° C on the middle rack for between 15 and 30 minutes (until they are golden brown).
Then take them out of the oven and let them cool down.
Variations: Put the cleaned blueberries in the middle of the dough before baking or separate 1/4 of the dough and stir it with cocoa powder (bake as a marble cake) or after the baking time - when the muffins have cooled down - cover them with chocolate icing.
