In a large bowl, beat egg until light and fluffy. Add 1 c milk and melted butter.
Add flour, baking powder, sugar, and salt and mix until moistened. Stir in chocolate chips.
Heat griddle over medium-high heat. Melt about 1 tbsp butter (can also use cooking spray, but butter is better!). Pour about 1/4 c batter onto griddle for each pancake. Cook until bubbles form and pop on the surface, then gently flip. Cook on the other side for 2-3 minutes. Serve warm with butter, syrup, and whipped cream.
