Experience the Southern style of pie baking in cast iron with this super-delicious dessert recipe! Place butter in your cast iron pan, then place the pan in your preheated oven, to melt. Sprinkle in brown sugar and heat some more while you peel and cut your apples. Place a pie crust in the buttery sugar, and top with sliced apples, sugar and cinnamon. Repeat the layers and top with sugar and dot with butter. Make vents in top crust and bake up beautifully golden. Get the recipe for Grandma's Iron Skillet Apple Pie.
