Instructions
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.
2 cups old fashioned rolled oats, 2 cups unsweetened almond milk, ⅓ cup pure maple syrup, 2 teaspoons ground cinnamon
The next morning, preheat the oven to 375 degrees and grease an 8x8" 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.
1 large egg, 1 teaspoon baking powder, 1½ cups fresh or frozen blueberries
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.
1 cup old fashioned rolled oats, ½ cup all purpose flour, ½ cup brown sugar, 1/4 teaspoon salt, ½ cup coconut oil
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!
Notes
Pro tip: The streusel topping may be made up to a few days in advance and stored in an airtight container in the fridge until ready to use. It may also be omitted entirely if you prefer!
Store leftovers in the refrigerator for up to 5 days. It may also be frozen for up to 3 months.
Make this baked oatmeal vegan by substituting the egg with a flax egg or egg replacement.
