Bake the granola for 10 minutes. Use a fork to gently break the granola apart and then rotate the pan to help it cook evenly. Bake for another 10 minutes until is golden brown.
Let the granola cool completely, about 45 minutes or so. then top with dried cranberries or dark chocolate chips, if desired.
Notes
Store the granola in an airtight container at room temperature or in the refrigerator for up to 1-2 weeks. Or freeze in a sealed freezer bag for up to 3 months.
Variations for Low FODMAP Granola
One of the best things about making your own granola is making it your own. These are some other ingredient variations if you are on a low FODMAP diet.
Swap out the peanut butter for almond butter.
Change the walnuts for macadamia nuts or pecans. If you use almonds, limit to 10 nuts per serving or 12 grams to limit FODMAPs.
Experiment with spices by substituting the cinnamon for ¼ teaspoon of nutmeg or ½ teaspoon of ginger.
Many dried fruits are high in FODMAPs; however, dried cranberries are low FODMAP in up to 1 tablespoon or 15 grams. Or you can substitute with dried goji berries, which are also low in FODMAPs, in 3 teaspoons (10 grams) per meal.
