Set your oven to preheat at 350°F (175°C), then grease a 10-inch skillet or pie pan with a portion of the melted butter.
02 -
In a saucepan over medium heat, toss in the apple cubes, white sugar, brown sugar, cinnamon, nutmeg, water, and orange juice. Stir on and off while you bring it to a bubbling boil.
03 -
Turn the heat down to medium-low once the mixture boils. Let it simmer gently for 5 minutes, then keep stirring and cook for 5 more minutes. The apples should soften up but still keep their shape.
04 -
Blend the reserved 2 tablespoons of water with the cornstarch in a tiny bowl until smooth. Pour this mixture into the apples while stirring. Continue cooking and stirring for 3-4 minutes until the liquid thickens.
05 -
Take the apple mixture off the stove. Mix in the ⅛ teaspoon of vanilla extract, let it cool in a heatproof bowl, and stir in ½ cup caramel sauce at the end.
06 -
Combine the cinnamon, brown sugar, and white sugar from the base ingredients in a mixing bowl. Divide what you mix into two parts.
07 -
Take the melted butter from earlier, and split it equally into two portions.
08 -
Grab one bowl of the melted butter and whisk it with the egg, cream, vanilla extract, one sugar-cinnamon portion, and the flour. Stir until smooth.
09 -
Slice all the cinnamon rolls into four smaller pieces each. Toss these pieces in the custard mixture and coat every piece fully.
10 -
In the bowl with the apple filling, mix in the soaked cinnamon roll pieces. Make sure to only use most of the liquid, not all of it, but use all the apples. Fold it all together lightly.
11 -
Pour everything into the greased skillet or pie pan. Spread it out evenly to form a smooth layer.
12 -
Drizzle the rest of the melted butter over the casserole and sprinkle on the rest of the cinnamon-sugar mixture evenly across the top.
13 -
Stir together all the crumble topping ingredients in a small bowl until you get a crumbly texture. Scatter it over the dish.
14 -
Put in the oven and cook for 25-30 minutes. Once the top turns golden and the middle has firmed up, take it out.
15 -
While waiting for the casserole to cool just a bit, stir the cinnamon roll icing along with the powdered sugar, half-and-half, and vanilla until it's silky smooth.
16 -
Drizzle the icing over the warm casserole and finish it off with an extra splash of caramel sauce if you'd like. Enjoy warm!
