Preheat oven to 225F. Place a sheet of parchment paper on a cookie sheet and spray liberally with cooking spray. Set aside.
In a medium size bowl, combine the granulated sugar, ground cinnamon, shortening, light corn syrup and vanilla extract. Mix with fork until the mixture is uniform and crumbly. Spread on parchment lined baking sheet, flattening with your hands and shaping into a rough square about 1/4 inch or so thick. Bake until mixture is melted and somewhat bubbly, about 30 minutes.
