In a mixing bowl, whisk together the flour, sugar, baking powder, and salt.
In another bowl, combine the milk, egg, and melted butter.
Pour the wet ingredients into the dry ingredients and mix until just combined.
Gently fold in the fresh blueberries.
Heat a non-stick skillet or griddle over medium heat and lightly grease it.
Pour 1/4 cup of batter onto the skillet for each pancake.
Cook until bubbles form on the surface, about 2-3 minutes.
Flip the pancakes and cook for another 2-3 minutes until golden brown.
Remove from the skillet and keep warm while cooking the remaining pancakes.
Serve warm with maple syrup and extra blueberries on top.
