1. Gather all your measured ingredients on a clean counter.

2. In a medium-sized bowl, add the rolled oats, protein powder, chia seeds, and a pinch of salt. Use a whisk or spoon to mix them thoroughly, breaking up any clumps of protein powder.

3. Pour in the unsweetened almond milk, Greek yogurt, maple syrup (if using), and vanilla extract.

4. Stir all the ingredients together vigorously. Make sure there are no dry pockets of oats or protein powder clinging to the bottom or sides of the bowl. The mixture should look consistent and slightly thick.

5. Gently fold in your fresh or frozen berries. If using frozen berries, they will thaw and release some color as the mixture chills, which is perfectly fine.

6. Divide the mixture evenly into individual serving jars or airtight containers. Mason jars work wonderfully for this, as they are easy to store and transport.

7. Cover the containers tightly and place them in the refrigerator. Allow them to chill for a minimum of 4 hours, but ideally overnight. This allows the oats and chia seeds to absorb the liquid and thicken, creating a creamy texture.

8. When you’re ready to eat, take a container from the fridge and add any desired toppings like extra fresh berries, a sprinkle of cinnamon, sliced almonds, or a drizzle of nut butter. Enjoy cold!
