Since slow cookers often cook differently, the first time you cook a cake in the slow cooker may take some trial and error to find the right amount of time to cook the cake to doneness. Start gently lifting the cover at about 2 hours, pressing the center of the cake lightly with your finger. If it doesn't spring back to the touch, replace the cover, and check every 15 minutes until done.
A Watched Crock Never Cooks... A slow cooker that's opened doesn't cook, so try not to peek! Keep the cover on unless a recipe tells you to remove it. Removing the cover allows heat to escape and adds 15 to 20 minutes to the cooking time each time you peek.
Baking spray with flour is like nonstick cooking spray, but with the addition of flour. When used in this recipe, it makes the slow cooker cleanup quick and simple!
