Preheat the oven to 450 degrees. Place 8-inch cast iron skillet in oven to warm as oven heats.
Into a food processor add flour & salt. Blend to combine.
Next add in milk, eggs & 1 1/2 tbsp melted butter. Blend until all ingredients completely combined & no visible lumps.
When oven is pre-heated, remove skillet from oven. Add the remaining 1 1/2 tbsp butter to the skillet. (Be careful, the skillet will be very hot & melt the butter quickly). Swirl around butter until skillet is coated.
Immediately after butter is melted in skillet, pour in your batter.
Place skillet back in oven and bake for 18-20 minutes. *The sides of the pancake will begin to rise on the sides and sometimes even the middle. Wait until the tops are browned & crispy before removing from the oven.
When pancake is cooked, sprinkle on chocolate chips, powdered sugar & maple syrup. Serve & ENJOY!
