Place all dry ingredients in a mixing bowl and whisk together.
Add remaining ingredients, except 3 tablespoons (un-melted) butter.
Whisk with a fork until no dry spots remain, but the batter is still lumpy.
Place a griddle or skillet over medium heat. Add remaining butter and melt (if using skillet, melt butter and make pancakes in batches).
Pour ⅓ cup batter over melted butter and lower heat to medium-low. Cook pancakes until the top begins to bubble and barely set, 3 to 4 minutes.
Flip and continue to cook until set, about 2 to 3 minutes. Remove from heat and serve.
