Sift together the flour, baking powder, sugar, and salt in a large bowl. In a separate bowl, whisk together the milk, melted butter, egg, and honey. Create a well in the dry ingredients and pour in the wet mixture. Stir gently until the batter is smooth but not overmixed. Preheat a lightly oiled skillet or griddle over medium-high heat. Pour ¼ cup of batter per pancake onto the hot surface. Cook for 2 to 3 minutes, until bubbles form on the surface and edges are set. Flip and cook until golden brown on the other side. Repeat with the remaining batter. Serve warm with extra honey, fruit, or your favorite toppings.
