For a richer flavor, toast the oats and almonds in a dry pan for a few minutes before adding them to the mixture. Feel free to customize the mix-ins with your favorite nuts, seeds, and dried fruits. Chocolate chips, shredded coconut, or chopped apricots would also be delicious additions. If you prefer a softer bar, reduce the amount of crispy rice cereal. Store the snack bars in an airtight container at room temperature or in the refrigerator for longer shelf life.
