In a medium mixing bowl, combine 1 cup rolled oats, 2 scoops of protein powder, 1 tablespoon of chia seeds, and a small pinch of salt. Whisk everything together until evenly combined. This helps distribute the protein powder and chia seeds throughout the oats so that they thicken uniformly later. The chia seeds will absorb liquid overnight and create a creamy, pudding-like texture, while the protein powder adds body and flavor.

Pour in 1 cup unsweetened almond milk, ¾ cup Greek yogurt, 1 teaspoon vanilla extract, and 1–2 teaspoons of your preferred sweetener, such as stevia, allulose, or maple syrup. Stir slowly at first to incorporate the dry ingredients, then whisk more thoroughly to ensure the protein powder dissolves completely and no clumps remain. The mixture should look smooth, slightly runny, and pourable — this is normal because the oats and chia will absorb much of the liquid overnight. If the mixture looks too thick right away, add 2–3 tablespoons of extra milk to loosen it slightly.

Divide the mixture evenly between two mason jars or small airtight containers, filling each about three-quarters full to leave room for expansion and toppings later. Use a spoon or spatula to scrape down the sides and smooth the surface. Seal each jar tightly with a lid or plastic wrap to prevent moisture loss and keep flavors fresh. Place the jars in the refrigerator and let them rest for at least 6 hours, or ideally overnight. During this time, the oats will soften and absorb the liquid, while the chia seeds will swell and thicken the texture into a creamy, cold porridge.

The next morning, open your jar and give the oats a good stir. If they look too thick, add a splash of milk and mix until you reach your desired consistency. Taste and adjust sweetness if needed. Add your favorite toppings such as sliced bananas, mixed berries, peanut butter drizzle, cocoa nibs, or crushed nuts. You can enjoy them straight from the jar for a chilled, refreshing breakfast, or warm them in the microwave for about 30–45 seconds if you prefer a cozy, pudding-like version.
