What Are the Benefits of Overnight Oats?

Make-Ahead: You can whip up several of these on the weekend and have breakfast ready to go for the week. They just take minutes to put together.

No Cooking Involved: The oats soften in the liquid as it sits in the refrigerator, which means no cooking is needed.

Super Healthy: Breakfast doesn’t get much healthier than this! The combo of fresh or frozen fruit, whole grains, and other nutritious add-ins provides fiber, protein, antioxidants, and valuable minerals.

Eat On the Go: Whether you have just a few minutes before you leave for the day or need to eat breakfast in the car or at your desk, this breakfast-in-a-jar fits the bill! Eat these overnight oats cold or warm. (Read on for tips for serving.)

Super Tasty: With a balance of sweet, salty, and texture, our variety of overnight oat recipes will make the whole family happy. Today’s recipe–Peanut Butter Cup Overnight Oats–is one of my favorites. It’s like a dessert in a jar.

In just four simple steps, you can throw together your overnight oats and be ready for the week. This particular recipe uses rolled oats, pure maple syrup, peanut butter, ground flaxseed, mini chocolate chips, bananas, chopped peanuts, and almond milk. Here’s the basic method:

1.  Build the Base: In a clean 10-ounce or 12-ounce mason jar, pour in your favorite (unsweetened) milk. Add old-fashioned or rolled oats and your all-natural sweetener of choice (pure maple syrup or honey). 
2. Add Fruit: Bananas are the starring fruit in this version, which adds more sweetness, flavor, and nutrition. When adding bananas, you can add them ahead of time if you don’t mind them getting mushy. We prefer to add bananas right before serving, however.
3. Add Toppings: Pour in the remaining add-ins. For this recipe, it’s peanut butter, ground flaxseed, mini chocolate chips, and chopped peanuts.
4. Shake and Refrigerate: Seal and shake. Set in the refrigerator for up to 3-5 days.

Do I Eat Overnight Oats Warm or Cold?

We hear this question a lot. The best way to serve overnight oats is…whatever you like best! Eating them cold or warm works.

Serve Overnight Oats Cold: Shake the jar. Stir in a little extra milk if it’s too thick and more sweetener if you’d like. Grab a spoon and eat your oats cold. This is the perfect solution for those mornings when you’re on the run!

Serve Overnight Oats Warm: This is our preferred way to serve overnight oats. Shake the jar and then remove the lid. Warm the oats in the microwave for about 45 seconds. Stir. Add more milk or sweetener as needed. Warm up even more, if desired.

Can I Freeze Overnight Oats?

As cookbook authors and long-time freezer meal evangelists, our professional opinion is that this is one dish that won’t freeze and thaw well. If you’d like a freezer-friendly oat recipe, try one of our Baked Oatmeal recipes:

Prep a few of these overnight oats ahead of time and enjoy healthy, hearty breakfasts throughout the week.
