In a small bowl, combine the flour, brown sugar, and butter.
Use a fork to mix together to resemble crumbs. Set aside.
Open the cinnamon roll container and separate the rolls.
Place them in a 9x13 baking dish that's been sprayed with nonstick baking spray.
Pour the heavy whipping cream over each roll and in between the rolls.
Next, pour the apple pie filling into a bowl, and use a knife to cut the apples into smaller pieces. Then pour the apples over the rolls and in between the rolls just like with the heavy whipping cream.
Cover the apples and the rolls with the crumble.
Bake at 350°F for 35 minutes or until the rolls are golden brown.
Remove from the oven and allow to cool on a cooling rack.
Be careful the baking dish will be piping hot, and the sugar and cream will be bubbly. The bubbles will settle and thicken.
Notes
Serve warm from the oven with a sprinkling of powdered sugar.
