Prepare Apples slices. Use a Cast Iron Skillet or other oven safe skillet. Spray skillet to ensure it doesn't stick. Put down layer of Brown Sugar and Granulate Sugar. Place slices of butter on top of sugar and then layer apples on top. Cook until bubbly and brown, move apples around to speed up cooking time (about 4-7 minutes).
Once everything is bubbly, pour your pancake batter over your apple mixture, be sure to spread it around as much as possible.
Place in Oven above the middle level and bake until firm/set about 15/20 minutes.
Remove and let sit for about 3-5 minutes and then flip onto serving plate.
