This was sent to me by KAF and it looks like such fun, my family loves cheesecakes and this would be so easy. The description they give is: a simple and easy way to make individual servings of cheesecake that are perfectly portable. Your slow cooker is the key to creating the warm, moist environment that's best for baking cheesecakes. I added a few drops of food coloring just for fun and to make them show up better A hint they also supplied was "The slow cooker method works well for almost any cheesecake batter. Imagine a buffet of your favorite flavors, each in a perfect little jar!" Cheesecakes will stay fresh in their jars in the fridge for up to a week.
