Preheat Crockpot on high.

Prepare the angel food cake mix according to package.

In a separate bowl mix together pumpkin, spice, & vanilla.

Fold pumpkin mix into angel food mix until well incorporated.

Place clean paperless sweetened condensed milk can in the center of a 5 qt or larger crockpot. Spray the entire crockpot and can with baking spray to avoid sticking.

Pour cake mix into crockpot around can, cover, and let cook on high for 2 hours.

After two hours check cake with a toothpick to make sure it is cooked through, it should also be pulling away from the sides of the crockpot.

Carefully remove the can and gently flip the cake out on to a baking rack to cool.

Return the can and 2 cups of water to the crockpot for the caramel to continue to cook for 2 hours while the cake cools.

When done remove the can and allow to cool. Carefully open to reveal the carmel. Serve with the cake.
