Add 1 tablespoon of the oats, the chia seeds, almonds, water, stevia, and vanilla in a blender. Blend until smooth. Add a quarter cup of blueberries (fresh or frozen) to the milk and pulse until smooth.
Pour the rest of the oats in a bowl. Pour the blueberry plant-based milk over the oats. Stir to combine. Cover and refrigerate at least two hours, or overnight.
Once the oats are done, pour into serving dishes and top with granola and remaining fresh blueberries.
If calories are important to you, substitute 1¼ cups unsweetened almond milk for the almonds and water. I like using raw almonds because you get more of the nutritional value, however there are more calories and fat. If you're subbing store-bought almond milk for the almonds and water, be sure to add the chia seeds too. The chia seeds are important for absorbing the liquids and creating a thicker oatmeal.If you prefer a thicker overnight oats, increase the chia seeds. If you prefer thinner, reduce the chia seeds.If you don't want to use Stevia, feel free to sub in a tablespoon of agave or maple syrup.
