Preheat oven to 350℉.

In a mixing bowl -  add the flour, sugar, baking powder and combine with a whisk.

Next add the eggs, vegetable oil and buttermilk. Mix with a hand mixer until combined. Add the vanilla and mix to incorporate.
Stir in blueberries.

Line a muffin tin with baking papers and fill nearly to the top. I use an ice cream scoop to add the batter.

Bake 18-20 minutes. Insert a toothpick in the center to ensure doneness, it should come out clean. Allow to cool before serving.
