Beat the egg and Stevia thoroughly, then add the milk and the rest of the dry ingredients, and keep beating.
Lastly, add the blueberries and mix with a spoon.
Pour the mixture into a buttered metallic baking pan for 6 muffins, or into individual silicone baking molds.
Put in the oven preheated to 375°F for 15-20 minutes, until you can insert a toothpick or a match and it comes out clean.
Allow to cool and remove from the mold.
