First, make a fire and let it die down.
Then, melt the butter in the cast iron skillet over the fire.
Remove the skillet from the heat and stir in the sugar.
Add the eggs and mix quickly so the eggs don't cook.
Mix in the flour and baking powder until well incorporated.
Stir in the chocolate chips.
Place your cast iron skillet on top of the hot rocks (or grill grate).
Cover with the lid of your dutch oven or aluminium foil.
Place a few hot coals or hot rocks on the lid.
Let it bake! The cooking time will depend on the temperature of the coals but it can take anywhere between 20 minutes to 1 hour.
