Whisk 3/4 cup plus 2 tablespoons milk, egg, and 1 tablespoon melted butter together in a separate bowl. Mix into the flour mixture until batter is fully combined.
Heat 1 tablespoon butter in a skillet over medium-low heat. Drop batter, 1 tablespoon at a time, onto the heated skillet. Cook until bubbles form, 1 1/2 to 2 minutes. Flip and continue cooking until brown, about 1 minute more. Lay on plate lined with a paper towel to help soak up excess butter. Repeat with the remaining batter.
