Preheat oven to 325 degrees Fahrenheit.
Mash the bananas into a large mixing bowl.
Add the melted coconut oil or butter, maple syrup, almond butter, vanilla, and coconut or brown sugar. Mix well.
Add all remaining ingredients and mix together.
Add to a baking tray lined with parchment paper and spread evenly.
Bake for 45 minutes, stirring halfway.
Turn the oven off and let sit another 20 minutes to crisp. This granola takes longer to crisp than most because of the banana, so letting it sit in the off oven will help it crisp without burning!
Remove from the oven, let cool and then break apart into clusters. Serve with yogurt, on top of a smoothie or enjoy as a snack!
