Preheat the oven to 330°F (165°C) and grease a 6-cup muffin tin; set aside.
In a mixing bowl, whisk together the applesauce or mashed banana, honey or agave, and vanilla until smooth.
Add the cinnamon, salt, and rolled oats to the wet mixture and stir until the oats are evenly coated.
Portion the mixture into the 6 prepared muffin cups, pressing the mixture up the sides with the back of a spoon to form cups.
Bake for 12 minutes, then remove from the oven and press the sides again with a spoon to help shape the cups.
Let the granola cups cool in the tin for 10 minutes before carefully removing to prevent crumbling.
Serve with yogurt or fresh fruit, or freeze for later use if desired.
