Preheat oven to 180 celsius. Grease a 6" tart Pan. Set aside
Bake for 20 minutes, until the granola is toasted on top. Transfer tart pan to a wire rack, and cool until they reach room temperature. Tart will dry out and crisp up while it cools.
Gently remove the granola tart from the tart tin, fill with your desired fillings and serve immediately.
