Preheat your oven to 450 degrees F

In a cast iron skillet or regular skillet melt 2 tablespoons of butter. Pour out into a large bowl

To the skillet melt another 4 tablespoons of butter over medium high heat

Add in the thinly sliced apples and let them saute for a minute

To the apples add in the brown sugar and cinnamon, letting them cook another minute

While the apples are cooking make the batter. To the bowl with the melted butter add in the eggs, flour, milk, salt, and vanilla extract. Make sure to whisk very well- you don’t want the batter to have clumps of flour

Turn the heat off of the apples and pour the batter over the top of the apples

Put the skillet into the preheated oven and bake until the pancake is puffed and a light golden brown, about 18-20 minutes

Take out the puffed pancake and let it cool slightly before dusting with powdered sugar and serving! Don’t worry, the pancake will puff after you take it out. Enjoy!
