Start by collecting all the ingredients listed above. This will make the preparation process smooth and efficient.
In a mixing bowl, combine 1/3 cup of old-fashioned rolled oats, 1/3 cup of plain Greek yogurt, and 1/3 cup of unsweetened almond milk. Stir until well combined.
To the oat mixture, add 1 tablespoon of chia seeds, 1/2 tablespoon of honey, 1 teaspoon of vanilla extract, and 1/4 teaspoon of cinnamon. Mix thoroughly to ensure all the ingredients are evenly distributed.
Gently fold in 1/4 cup of blueberries, being careful not to crush them. This will maintain their shape and provide bursts of flavor throughout your oats.
Pour the mixture into a jar or container with a lid. Make sure it's sealed tightly to keep the oats fresh.
Place your container in the refrigerator and let it chill overnight, or for at least 4 hours. This allows the oats to absorb the liquid and flavors.
In the morning, give your oats a good stir. Top with 2-3 tablespoons of granola and, if desired, a drizzle of honey for extra sweetness. Enjoy your nutritious Blueberry and Granola Overnight Oats!
