  • Total Time: 4 hours 10 minutes
  • Yield: 2 servings

Ingredients

Scale

1 cup old-fashioned rolled oats

1 cup plain nonfat or 2% Greek yogurt

1 scoop (about 30 g) vanilla or unflavored protein powder

1 cup milk of choice (dairy or high-protein milk)

2 tablespoons chia seeds

23 teaspoons maple syrup or honey, to taste

1 teaspoon vanilla extract

1/2 teaspoon ground cinnamon

Pinch of salt

1/2 cup fresh or frozen berries (optional)

1/2 sliced banana (optional)

2 tablespoons peanut butter or almond butter (optional)

12 tablespoons chopped nuts (optional)

1 tablespoon ground flaxseed (optional)

Instructions

1. In a medium bowl, stir together the rolled oats, chia seeds, cinnamon, salt, and protein powder until evenly combined.

2. Add the Greek yogurt, milk, vanilla extract, and maple syrup or honey, then stir or whisk until the mixture is smooth and no dry pockets remain.

3. Taste the mixture and add a little extra sweetener if you prefer it sweeter, or a splash more milk if it seems very thick.

4. Fold in berries, sliced banana, or a spoonful of nut butter if you want those flavors mixed throughout instead of just on top.

5. Divide the mixture evenly between 2 jars or containers with lids, smoothing the tops with the back of a spoon.

6. Cover the jars and refrigerate for at least 4 hours, or overnight, until the oats are soft and the mixture is thick and creamy.

7. In the morning, stir each jar, add a bit of milk if needed to loosen the oats, and top with extra fruit, nuts, or nut butter.

8. Enjoy the oats cold straight from the jar, or gently warm them in the microwave in short bursts if you like them warm.

Notes

Use a high-protein milk and a full scoop of protein powder if you want each serving to reach about 30 grams of protein.

For a dairy-free version, choose a thick plant-based Greek-style yogurt, plant-based protein powder, and soy or pea-protein milk.

Store the jars in the refrigerator for up to 4 days and stir in a splash of milk if the mixture thickens too much as it sits.

You can freeze the oats for up to 1 month, then thaw overnight in the fridge and stir well before serving.

Keep very crunchy toppings like granola or nuts for just before eating so they stay crisp rather than getting soft overnight.
