Add the coconut milk, honey, vanilla, and 1 cup water in a large pot and bring to a boil.
Stir in the oats and bring to a boil stirring constantly.
Reduce the heat to low and cover.
Simmer on low for 5 minutes stirring every once and a while. Add in 1/2 cup blueberries, cover, and simmer for another 5 minutes or until the oats are cooked through and the mixture is super creamy.
Remove from heat and add in the remaining 1/2 cup blueberries and brown sugar.
Cover and allow to sit for another 5-10 minutes to really thicken up.
