Preheat oven to 350°. Grease mini pie or baking dish with coconut oil.
Combine all ingredients in a large bowl. Pour into pie dish.
Bake for 25 minutes, until edges are lightly browned.
If enjoying right away, top with peanut butter and use a knife to serve.
If preparing the night before, let cool completely and pop baked oatmeal out of baking dish. In the morning slice into pieces, reheat in the oven and top with peanut butter before serving.
