In a large mixing bowl, whisk together oats, chia seeds, cream cheese, Greek yogurt, maple syrup, vanilla extract, and almond milk until smooth. Let sit for 5-10 minutes.

Prepare blueberries by microwaving frozen ones for 30 seconds or rinsing fresh blueberries.

Spoon approximately ¾ of the mixture into clean jars, layer in some prepared blueberries, and repeat.

Seal jars tightly and refrigerate for at least 4 hours or overnight.

Serve cold from the jar or microwave for 30 seconds. Add optional toppings if desired.
