Kittencal'S German Apple Puff Pancake - cooking recipe

Ingredients

4 tablespoons butter, divided (one more tablespoon butter won't hurt)
4 large apples, peeled and sliced
3/4 cup flour
3/4 cup milk (or use half and half cream)
1/2 teaspoon salt
1/4 teaspoon baking powder
1 tablespoon sugar (optional or to taste)
4 large eggs
1/3 cup sugar (can use 1/2 cup sugar)
1 teaspoon cinnamon (or to taste)

Preparation

Set oven to 400 degrees F.
Spray two 8-inch round cake pans with cooking spray.
Place 2 Tbsp butter in each of the pans.
Place the pans in the oven and bake until the butter has melted; remove from oven.
In a bowl, beat the flour, 1/4 teaspoons baking powder, sugar (if using) salt, milk and eggs until smooth, then allow to stand for 30 minutes.
Arrange the apple slices into the two pans onto the melted butter.
Re-whisk the flour/egg mixture again then divide the batter evenly between pans, over the apple slices.
Mix the sugar and cinnamon; sprinkle over the batter in each pan.
Bake until puffed, and golden brown, about 20-25 minutes.
