How to make
Crack the egg into a large bowl, add the sugar and beat with a mixer for 10 minutes.
Pour the oil and white wine. In another bowl, mix the two types of flour with the baking powder, cinnamon and a pinch of salt.
In portions, pour the dry mixture into the liquid, by stirring with a spoon. Add the washed and dried blueberries.
Homogenize carefully. Fill 2/3 of paper muffin cup with the prepared mixture. 12 muffins are obtained.
Bake the muffins at 360°F (180°C) in a preheated oven with a fan for about 25-30 minutes.
Cool the baked muffins on a wire rack. Sprinkle them with powdered sugar.
