In a large mixing bowl, whisk together flour, baking powder, and salt until evenly combined. Set aside.

In another bowl, crack the egg and beat it until smooth. Stir in milk and melted butter until well mixed.

Pour the wet ingredients into the bowl with the dry ingredients and stir gently until just combined.

Fold in cheddar cheese and chives until evenly distributed in the batter.

Preheat a non-stick skillet over medium heat and lightly grease with butter or oil.

Pour 1/4 cup of the batter onto the skillet for each pancake and cook for about 2 minutes.

Flip the pancakes and continue cooking for 1-2 more minutes until golden brown.

Keep pancakes warm until serving, adding toppings like sour cream if desired.
