Preheat your oven to 350F while you prepare your oatmeal
In a large bowl, mix together all of your oatmeal ingredients until evenly combined. Transfer into baking dish of choice, and bake for roughly 20 minutes, or until top is lightly golden brown.
To prepare icing sugar, blend coconut sugar on high until it becomes powdered. Mix with water, a few teaspoons at a time until an icing consistency forms. Start with less than you think you need and as more as you go along! Alternatively, use warmed coconut butter to top.
