Diabetics don't have to give up desserts! This is low in sugar. If you don't want the sugar in the Craisins, rinse them a little in cold water and drain. This removes some of the sweetener on them. Or use raisins instead. Dry buttermilk powder can be found in the baking section of the store. It is great to have on hand for baking.
This was adapted from a recipe in "Desserts for Diabetics", by Mabel Cavaiani. NOTE: This is a low-rise cake, like a snack-cake or brownie.
