Make the date caramel: Put the dates, ½ cup of milk and 1 teaspoon of vanilla extract into a blender or food processor and blend until the dates liquefy. Set aside.
Toast the coconut: Preheat the oven to 350 °F and line a small baking sheet with parchment paper. Sprinkle the coconut in an even layer on the baking sheet and toast in the hot oven for about 3 minutes. Stir, and continue to toast for 2 to 3 more minutes until coconut is lightly golden-brown.
Turn the oven up to 375 °F and lightly spray a 9x13-inch baking dish with nonstick spray.
Reserve about 2 tablespoons of date caramel for topping. Whisk the rest of the date caramel with the applesauce in a large bowl.
Beat the egg and egg white into the applesauce/date mixture.
Whisk in the baking powder, vanilla extract, coconut extract, cinnamon and salt.
Stir in the milk
Stir in the oats
Stir in ½ cup chocolate chips
Put the baking dish in the oven and bake at for 45 minutes, until the oatmeal is golden-brown at the edges. Oatmeal is done cooking when a toothpick/knife/skewer inserted into the center of the oatmeal comes out clean.
