Prepare the oats:

Place the oats, milk, sweetener, and cinnamon in a medium to large bowl and stir. Cover with plastic wrap and refrigerate over night.

Do not add the egg or baking powder.

The next morning, preheat the oven to 375 degrees and grease an 8×8″ square baking dish. Set aside.

Stir the beaten egg and baking powder into the oatmeal mixture until well combined, then gently stir in the blueberries. Pour the mixture into the prepared baking dish and spread evenly.

Prepare the streusel:

Stir the 1 cup oats, flour, sugar and pinch of salt together in a medium bowl. Stir in the melted coconut oil until combined. Sprinkle the streusel evenly over the oatmeal.

Bake for 30-40 minute on the middle rack of the oven until the majority of the liquid has been absorbed. If the streusel begins to brown too quickly during baking, cover loosely with foil for the remainder of the baking time.

Remove from heat and cool on a wire rack for 10-15 minutes. Enjoy!
