In a large mixing bowl, whisk together the flour, baking powder, salt and sugar until combined. Then stir in the milk, egg, butter and vanilla. Mix until just combined. The batter will be lumpy.
Fold in the chocolate chips. Then let the batter rest for approximately 5 minutes.
Preheat a Blackstone Grill over medium high heat (approximately 400 degrees F). Rub butter on the grill to keep the pancakes from sticking to the grill.
Pour the batter onto the grill in approximately ¼ cup measurements. Gently spread the batter out some.
Cook for 3-4 minutes until you see bubbles start to form and burst on top of the batter. Flip and cook the opposite side until golden brown. Remove the pancakes from the grill to a plate. Continue this process until all the batter is used.
Serve topped with your favorite toppings and enjoy!
