Set aside 1/2 cup of flour.
In a large bowl Add 2 1/4 C flour, sugar, salt, and yeast together until evenly dispersed and then set aside.
In a double boiler combine the water, milk, and butter together until the butter is melted and the mixture is hot to touch.
Pour the butter mixture into the flour mixture. Stir to blend. Then add in the egg and between 1/3 C to 1/2 C of the left over flour to make a soft dough.
Dough is ready when it pulls away from the side of the bowl and has an elastic consistency.
Knead the dough for about 3-4 minutes on a floured surface.
Grease a bowl, add the dough allowing it to rest for about 10 minute. Cover with a kitchen towel.
While the dough is resting make your apple pie cinnamon roll filling. Mix the cinnamon and sugar in a bowl and set aside.
Once your dough is ready, roll it out in a rectangle. Spread the butter on top then sprinkle the dough with cinnamon and sugar mixture, then spread the applesauce on top.
Roll up the dough tightly by squeezing the edges closed, then cut into 1- 1 1/2 inch wide pieces.
Prep your cast Iron Skillet (or circle baking pan if you don't have one) with non stick spray. Place cinnamon rolls into pan (you want the top to be the part where you can see the filling on the inside)
Put the skillet in a draft free area, that is warm and loosely cover with a kitchen towel to allow them to rise for 60-90 minutes.
As it gets time to bake them preheat the oven to 375 degrees and when oven is ready place in oven and bake for 25-30 minutes, until they are lightly browned.
While they cinnamon rolls are baking you want to make your frosting.
Combine the vanilla, corn syrup and lemon juice in a small bowl. Whip cream cheese and butter together. Continue to beat while adding the two mixtures together.
scrape the sides of the bowl and mix again, you want this mixed well.
Pour in powdered sugar and stir slowly until it starts to incorporate. Then mix on high for 5 minutes or until frosting starts to lighten in color. Scrape sides of the bowl and mix it together again briefly.
Once rolls have been removed from the oven, frost using half the amount made. let them cool and then frost again. The first layer of frosting will seep into the cinnamon rolls and the second layer will be the frosting on top. This gives them AMAZING Frosting that is oozy just the way cinnamon rolls need to be!
