An alternative baking method might be to follow directions as written, but bake the apple for 40 to 45 minutes or until cooked through, then add the granola, press in lightly, and put under broiler 1 to 2 minutes or until brown and crispy on top. Omit or change the type of nuts. Try pancake syrup or honey instead of maple syrup. Add some raisins or minced ginger. Increase the cinnamon. Make your own crispy topping instead of using granola. Whatever changes work for you based on your preferences and what you have on hand.
