Preheat oven to 375 degrees. Spray 6 ramekins or 1 8x8 pan with non-stick spray.
In a medium bowl, combine oats, spices, baking powder and salt. Stir together.
In a second bowl, crack and whisk the egg. Add the milk and whisk together. Add syrup and vanilla (if you're using it). Whisk the mixture while pouring in the melted coconut oil to keep it from getting solid again.
If you're using berries, put half on the bottom of the pan and reserve the rest for the top. If you're using nuts or chocolates chips or similar items, mix those in with the oats.
Pour the oats into the baking dish and the pour the liquid mixture over the top. Make sure all of the oats are in the liquid. If you used berries, top with remaining berries. Then sprinkle with coarse sugar.
Bake for 40-45 minutes in preheated oven until top begins to brown.
