Pumpkin Toffee Cheesecake

Why I Love This Recipe
I found this in a food community on livejournal. I attempted to make this once at Thanksgiving with disastrous results. It came out perfectly the second time around!
Ingredients You'll Need
Ingredients
1 Recipe For Crust:
1 3/4 cups (about 1 and 1/2 sleeves) shortbread cookies, crushed (I use Lorna Doone)
2-3 tablespoons butter or margarine, melted
1 Recipe For Cheesecake:
3 packages (8 oz. each) cream cheese, softened
1 1/4 cups packed brown sugar
1 can (15-oz.) LIBBY'S 100% Pure Pumpkin
1 can (5 fl.-oz can) CARNATION Evaporated Milk
2 large eggs
2 tablespoons cornstarch
1/2 teaspoon ground cinnamon
1 cup crushed toffee candies, (about 25 to 30) (note: It's easier to just buy a package of toffee bits. They should be located next to the chocolate chips and nuts at your local grocery store.)
1 Recipe For Topping:
1 cup (8 oz. container) sour cream, at room temperature
2 tablespoons granulated sugar
1/2 teaspoon vanilla extract (I prefer a few dashes of Amaretto)
Caramel ice cream topping
