In a medium-sized mixing bowl, combine the rolled oats and almond milk, whisking them together until smooth.
Add in the almond butter, chia seeds, maple syrup, vanilla extract, and a pinch of salt. Stir the mixture thoroughly until all ingredients are evenly blended.
Carefully fold in the fresh blueberries, ensuring you preserve their shape; be gentle to avoid mashing them.
Evenly distribute the oat mixture among four mason jars or airtight containers, making sure each jar is filled to about three-quarters full.
Close the jars with their lids securely and place them in the refrigerator overnight, or for at least 4 hours, allowing the oats to absorb the almond milk and soften.
In the morning, remove the jars from the refrigerator and give the oats a light stir to incorporate any ingredients that may have settled.
Finish each serving with a generous topping of additional fresh blueberries and a handful of sliced almonds to add a delightful crunch.
Notes
Present the oats in clear jars to beautifully display the vibrant blueberries and layers. Add a sprig of mint on top for an extra refreshing touch and a splash of color!
