This recipe is based on one from a Dr. Oz December 2011 episode where Chef Alton Brown was a featured guest. Alton Brown discussed how he lost 50 pounds and has kept the weight off for two years. One of his secrets is recipes like this no-bake, low-calorie chocolate pie. This satisfies your sweet tooth while substituting tofu for dairy products. Alton prefers coffee liqueur, but you can substitute just about any of your favorite liqueurs. Prep and cook times do not include the two hours chill time. This recipe is originally from Alton’s book, “Good Eats: The Early Years”. I have tweaked this to suit my preferences.
