Do you meal prep? I am a big believer in making at least a few things ahead of time to make the rest of the week easier, and overnight oats are a great example of that. They keep for up to 5 days in the refrigerator, which means you could easily double the recipe and have several breakfasts made ahead of time – and it only takes a few minutes. Plus, the sweet flavor and soft texture of the oats is a total treat.

I’ve already shared my Pecan Pie Overnight Oats recipe, and this scrumptious Apple Crisp Overnight Oats recipe is also a favorite. But this peanut butter overnight oats recipe might just be my favorite. If you like peanut butter, you’ve got to give this a try!

This Recipe Is…

  • Low On Prep: There are only a few ingredients here, and no peeling, chopping, or cooking!
  • Big on Flavor: With peanut butter, pure maple syrup, vanilla, and sea salt, there’s lots to love in this simple recipe.
  • Perfect for Busy Cooks: I can’t think of an easier, faster breakfast recipe. You really can just grab one and go! But it’s still 100% homemade and wholesome.
  • Healthy: Oats are a wonderful source of healthy fiber (gluten free, too!). Fiber is so important for your digestion. With plenty of water and fiber, your body has what it needs to properly digest food – which means you absorb nutrients better and feel better overall. Peanut butter gives you protein and fat, so this meal is well-balanced.

The Ingredients You’ll Need

You can jazz up overnight oats in all kinds of ways, but for this peanut butter version, these are the ingredients you will need:

  • Old Fashioned Oats: Also known as rolled oats, these are flattened oats that do well with soaking. Steel cut oats are harder to use for overnight oats, so I don’t recommend using them.
  • Almond Milk: I like unsweetened, vanilla almond milk for this.
  • Greek Yogurt: Plain Greek yogurt. You can use high-fat or reduced-fat, whichever you like.
  • Peanut Butter: Creamy or crunchy, it’s up to you.
  • Maple Syrup: Pure maple syrup gives the best flavor. Honey would also work.
  • Chia Seeds: For an even silkier texture and additional nutrients.
  • Vanilla: Pure vanilla extract.
  • Sea Salt: Or whatever salt you like to use.
  • Toppings: Blueberries, additional peanut butter, and chopped peanuts.

Are Quick Oats OK for Overnight Oats?

Sure! Quick oats are more finely cut than rolled oats, so they will become softer and have less texture than rolled oats – this may be preferable for some people, while others might like the more robust feel of rolled oats. Use what you have and what you love!

This recipe is so simple – if you can make a bowl of cereal, you can do this! And between you and me, it’s much more delicious than a bowl of ordinary cereal.

  • Combine the Ingredients. First, measure and combine the oats, almond milk, yogurt, peanut butter, maple syrup, chia seeds, vanilla, and sea salt in a bowl.
  • Mix Well. Stir the oatmeal mixture thoroughly, so that the peanut butter gets evenly blended into the rest of the ingredients.
  • Refrigerate. Divide the oatmeal into two containers (mason jars work well for this). Seal the containers and place them in the fridge overnight. 
  • Serve and Enjoy! Take one container of oatmeal out of the fridge the next morning, and stir it well. Top with a little bit of peanut butter, some blueberries, and some chopped peanuts. Enjoy!

Recipe Tips

Ready to make some peanut butter overnight oats? Great! These helpful tips will make the process easy, breezy, and tasty. Let’s do this!

  • Fruit Options: Blueberries are really good in this recipe, adding a pop of color and freshness. But you could also use other fruits like bananas, apples, raisins, dates, etc.
  • Add the Fruit Last: Make sure you add your fruit just before serving. If it sits overnight in the oatmeal, it can become mushy.
  • Jars, Bowls, and Containers: A mason jar is the classic choice for overnight oats, but you don’t have to use those. Lidded food storage containers are also fine, or even cereal bowls covered with plastic wrap. I do recommend mason jars if you are taking this breakfast in the car – they are less likely to spill!
  • Spices: If you like, sprinkle in a little cinnamon, pumpkin pie spice, or other flavoring to customize the recipe.
  • Hot or Cold: Not feeling the cold oats? Warm them up! To make these oats into a warm breakfast dish, just microwave them for a few seconds at a time, stirring each time, to make a creamy hot breakfast.

  • Hard Boiled Eggs: The ultimate portable protein, Perfect Hard Boiled Eggs are a great option to store in the fridge alongside your peanut butter overnight oats.
  • Maca Latte: A Maca Latte (or Golden Maca Latte) would be the perfect hot drink to pair with peanut butter overnight oats.

How to Store Overnight Oats

These should always be kept in the refrigerator, for food safety. Overnight oats will keep for about 5 days in the fridge, sealed in airtight containers or jars. It also helps make them good and cold, which is refreshing, especially in the summer! Want a warm breakfast? Don’t leave them out – just pop them in the microwave for a couple of short bursts, and stir well.

Can I Freeze Peanut Butter Cup Overnight Oats?

Actually, yes! If you want to store these even longer, then freezing is a great option. You can freeze overnight oats for up to three months in an airtight container. Thaw them out overnight in the fridge, and you’re good to go.
