Convection Oven Granola calls for a little wheat germ and egg white to help it clump.
Granola Bark Variation: To make bark, use 1/4 cup of ground flax in place of the 2 tablespoons. Also, add 1 tablespoon of water in with the wet ingredients. Press the granola down flat on the baking sheet, then put a layer of parchment over it. Set a second baking sheet over the parchment. Bake at 300 degrees F for 45 minutes with the second baking sheet nestled on top. Halfway through baking, lift up the second sheet. If the granola is pretty brown, continue baking covered with the sheet. If the granola is not brown enough, continue baking without the sheet. Remove from oven and let cool completely. Break into large chunks.
