Melt the butter and crush the oreos. Spread them evenly on the bottom of a springform pan. Press them down on the bottom and about halfway up the sides. If you don't want to use Oreos you can always make a Butter Crust from scratch instead. (Or you could use chocolate graham crackers if you can find them cheaper!)

Blend the softened cream cheese, sugar, vanilla, pumpkin, eggs, and pumpkin pie spice. I use a hand mixer so that there aren't any chunks of cream cheese left.

Pour into the springform pan on top of the crust.

Bake at 350F for 55 - 60 minutes.

When it's done baking, take it out and let it cool for a while. Pop it out of the springform pan.

Melt caramels (or make caramel sauce) and chocolate chips and drizzle on top. You could also add pecans to make it a true turtle cheesecake.
