Combine all wet ingredients (egg, buttermilk, vegetable oil, vanilla extract, sugar) in a medium sized mixing bowl. Whisk together well.
Separately, combine the dry ingredients (flour, salt, baking powder).
Combine the wet and dry ingredients, whisking until mostly combined (fine if there are a few lumps!). You can add a little more milk/buttermilk if the mixture is too thick.
You can add in the blueberries directly to the batter now, or add them to each pancake individually. We like to add them right into the batter.
Heat a nonstick pan over medium heat, add a little butter or cooking spray, and add batter to the pan. We can usually fit 3 pancakes at a time!
Cook the pancakes on one side until you see bubbles on the top.
Flip, cook another minute or two, then remove. Repeat! Adjust the heat as necessary.
Enjoy with syrup, yoghurt, honey, whatever you like to put on your pancakes!
