This recipe was cobbled together by my sister Mara. She was inspired by this recipe from William-Sonoma.
4 cups frozen blueberries
1/2 cup sugar
1/2 tsp ground cinnamon
4 tablespoons butter
2 packets instant oatmeal (I used maple brown sugar flavor)
Cook the blueberries in a little water until the juices start to come out. Pour into serving dish.'
Melt the butter. Add the remaining ingredients and cook until the sugar is melted. Stir to combine. Pour over the blueberries and serve hot.
