Preheat the oven to 350° F.
Spray a 9-inch pie pan with vegetable oil spray and coat it lightly with the graham cracker crumbs, tilting pan to spread the crumbs.
In a food processor or blender (a food processor makes the job easier), blend all the remaining ingredients. Process until very smooth, stopping to scrape down sides as needed. Pour into the prepared pie pan.
Bake at 350° F for about 1 hour, until small cracks start to form. Cool at room temperature about 20 minutes, then refrigerate.
Serve well chilled, cut into 8 wedges and topped with fresh fruit if desired.Servings:
