In a medium bowl, add oats, 1 cup almond milk and the juice of 2 Cara Cara oranges and stir. Let sit for 20 minutes, allowing oats to soak in liquid.
Preheat oven to 375°F. Grease a 9-inch pie pan with 1 tablespoon ghee and set aside. In a large bowl, combine egg, Turkish honey and remaining ghee and almond milk. Add soaked oats, Trek Mix, baking powder, salt and cinnamon and stir gently until combined.
Pour the oat mixture into the greased pie pan. Thinly slice the remaining Cara Cara orange and layer slices atop mixture. Sprinkle with sugar, if desired, and bake for 30 minutes, until the center is set. Turn the oven to broil (low) and cook until orange slices are caramelized, about 3 minutes. Let cool 10 minutes prior to serving.
