Greek Yogurt Overnight Oats Ingredients

You only need a few simple ingredients to get started. Once the base is prepared, you can personalize it with your favorite fruits, nuts, or other tasty toppings.
- Rolled oats: Regular or certified gluten-free rolled oats both work well.
- Milk: Use whichever milk you enjoy most. Whole milk, almond milk, soy milk, oat milk, or coconut milk all make delicious overnight oats.
- Greek yogurt: Plain or vanilla Greek yogurt both work nicely. If using vanilla yogurt, you may want to reduce the sweetener since it’s often already sweetened.
- Peanut butter: Creamy peanut butter adds rich flavor and extra protein. For peanut allergies, substitute another nut butter or your favorite seed butter.
- Vanilla extract: Adds warmth and enhances the overall flavor.
- Maple syrup: My favorite natural sweetener, but honey, brown sugar, or another sweetener can be used instead.
Recipe Notes
- These overnight oats are delicious served cold straight from the refrigerator or gently warmed before eating. I usually prefer mine warmed up.
- If the oats become thicker than you’d like after chilling overnight, simply stir in a splash of milk before serving until you reach your preferred consistency.
