In a large mixing bowl, whisk together the flour, sugar, baking powder, and sea salt.
In a separate bowl, combine the milk, egg, and melted butter. Whisk until smooth.
Pour the wet ingredients into the dry ingredients and gently stir until just combined.
Heat a non-stick skillet over medium heat and melt a small amount of butter.
Pour about 1/4 cup of batter onto the skillet. Cook until bubbles form, then flip and cook until golden brown.
Stack the pancakes on a plate and drizzle with chocolate sauce or your favorite toppings.
