Granola is often sweetened in one of two ways: maple syrup or honey. They offer a depth of flavor that table sugar doesn't. But they also help with the binding process and cluster formation. There are other sweeteners used in granola, like brown rice syrup or agave nectar. Some use brown sugar, too. But for a healthier experience, it's best to avoid granola that uses white sugar or corn syrup. And when you make your own, you can easily control the sugar.
