Using a food processor, blend oats until they resemble a chunky powder

Add milk, yogurt, maple syrup, and salt, blending to form a cohesive mixture

Add protein powder and pulse until incorporated

Pour the mixture into small jars and allow the mixture to thicken in the fridge for a few hours before adding toppings

Once the overnight oats are more solidified, you can add toppings such as peanut butter or berries

Enjoy the oats cold or heat them if you prefer (just be sure to add additional liquid before warming)
