Preheat the oven to 400ºF (200ºC).
Prepare a greased muffin tin.
Whisk together milk, yogurt, egg and vegetable oil. Set aside.
In a separate bowl mix the flour, baking powder, and sugar.
Stir in the blueberries until they are well coated.
Add the wet mix and stir.
Scoop batter into the muffin tin and place in the oven for 20 minutes.
The muffins are done when a toothpick inserted in the middle comes out clean.
