Add oats, almond milk, yogurt, blueberries, chia seeds, maple syrup, and vanilla into a bowl or mason jar. Stir well to combine. Seal the container with a lid and place it in the fridge overnight.

Take the container out of the fridge the next morning and stir the mixture. You may want to add a little more almond milk before serving. Top with fresh blueberries or toppings of choice and enjoy!
