Cook Time: is for one batch of pancakes.
In a small bowl, mix flour, salt, baking powder and soda, and sugar together with a fork.
In a large mixing bowl, combine buttermilk, vanilla, butter, and eggs until well-mixed. Fold in dry ingredients and blueberries until just incorporated. Do not over-mix (batter should be lumpy).
Heat griddle or large non-stick skillet over medium-low heat. Add dab of butter and scoop 1/3 cup of batter on griddle. Cook for 2 minutes (bubbles will appear), then flip and cook 1 minute more.
Pancakes should be golden brown. Repeat steps for remaining pancakes.
Serve with butter, maple syrup, and blueberries.
