In a large bowl, whisk together flour, cocoa, sugar, baking powder, and salt until well mixed.

Add milk, butter, and egg, and mix well until mixture is well blended.

Stir in chocolate chips.

Heat a skillet over medium heat until warm. Drop a pat of butter into pan and coat the pan.

Pour pancake batter slowly onto griddle, allowing batter to form small-to-medium-size circles (whatever size you prefer).

Wait until batter becomes bubbly before flipping over to the other side. Try to flip pancakes just once.

Repeat with remaining batter. Coat skillet with more butter in between batches as needed.
