Heat a griddle to 350°F or a skillet to medium heat.
Beat eggs in a large bowl, then add milk, vanilla extract, and oil. Whisk together.
2 eggs, 1 ¾ cups milk, 1 tablespoon vanilla extract, 4 tablespoons vegetable oil
Add the flour, baking powder, salt, and sugar. Mix until combined, but it is okay if there are lumps.
2 cups all-purpose flour, 2 tablespoons baking powder, 1 teaspoon salt, 2 tablespoons granulated sugar
Gently fold in the blueberries.
1 ½ cups fresh blueberries
Using a large spoon or ladle, drop batter on the heated skillet to make about a three-inch circle for each pancake, or whatever size you want to make them!
Flip the pancakes over once they are slightly browned. Cook each side for about two to three minutes.
Serve warm with maple syrup and butter. Top with additional blueberries, optional.
