Recipe can be made ahead and stored in the refrigerator for up to 6 weeks. For an added treat melt one teaspoon butter and one tablespoon of brown sugar in each muffin tin before filling. Absolutley wonderful! Please note that this recipe is written to use with Raisin Bran Flakes . . . if using All Bran you will need to soak in water as noted by previous reviewers This recipe is best if made in advance and stored in the refrigerator..
