Add the Greek yogurt, almond milk, vanilla extract, almond butter, and maple syrup to a mixing bowl. Whisk together until well combined.
Next, fold in the oats, chia seeds, cinnamon, and blueberries. Stir until well combined.
Add all of the ingredients to a large wide mouthed glass container with a lid and stir until everything is well combined.
Cover the container and place in the fridge for at least 2 hours or up to overnight.
After oats have chilled, remove them from the fridge and give them a stir. Add a few extra blueberries, sliced almonds, and lemon zest on top for serving!
