Why You’ll Love This Recipe

The peanut butter blueberry combination in these overnight oats is just like eating a peanut butter and jelly sandwich. Except, instead of bread, you’ve got healthy, fiber-filled oats instead.

You can eat them cold with a spoon, or add some extra liquid and drink them on the go! Alternatively, microwave your oats in the morning to eat them hot. There’s really no wrong way to enjoy overnight oats!

I think these are such a great breakfast option, because you can make them the night before (hence the β€œovernight” in the name). Then, all you need to do is grab and go in the morning, which is perfect when you’re rushing out the door to work or school.

Benefits of Peanut Butter Blueberry Overnight Oats

  • Peanut Butter. Peanut butter is loaded with vitamins and nutrients, and contains fiber and protein to keep you feeling full. It helps to lower bad cholesterol, manage your blood sugar, and is even good for your skin and hair!
  • Blueberries. Did you know that blueberries are full of antioxidants? That can help protect your body against some types of diseases, but they taste great too!
  • Oats. The oats part of overnight oats are another good source of fiber, which helps to keep you feeling full and gives you sustained energy for your day. They too can lower blood sugar and reduce the risk of heart disease!

Ingredients List

ingredients to make peanut butter blueberry overnight oats
  • Β½ Cup rolled or old fashioned oats
  • 1 Tbsp chia seeds (optional)
  • ΒΎ cup unsweetened vanilla almond milk
  • 1 Tbsp honey
  • Β½ cup blueberries (fresh or frozen)
  • 2 Tbsp peanut butter powder (such as PB2)

Ingredient Tips & Substitutions

  • Any type of oats are fine, so long as they aren’t instant. I’m using old fashioned today, but have used rolled many times as well
  • You can substitute in any other type of unsweetened milk for the almond milk if you’d like, such as macadamia, coconut, or even soy
  • The honey can be replaced by an equal amount of maple syrup or agave if preferred
  • You can substitute ΒΌ cup of creamy peanut butter in place of the peanut butter powder. I just like the way the powder dissolves better and offers a more potent taste. Feel free to substitute almond butter as well if you have a peanut allergy
  • While toppings aren’t necessary, feel free to add sliced bananas, additional fresh blueberries, some creamy peanut butter, or some blueberry jam to finish things off!

Variations and Mix-Ins

  • Greek Yogurt. Swap ΒΌ of the liquid for Greek yogurt. Blueberry or vanilla would be the best choices for flavors here, but you can use what you like. Greek yogurt adds protein and creaminess to the mix
  • Nuts and Seeds. Add extra brunch in your mix by adding nuts or seeds. I like peanuts, almonds, walnuts, or granola to top this, but feel free to make your own variation!

Recipe FAQs

Can I Use Frozen Blueberries in Overnight Oats?

Yes, you can use frozen blueberries in overnight oats. They’ll slowly defrost in your refrigerator overnight.
Β 
If you plan to eat your oats within a few hours, though, note that the berries may not be fully defrosted by then.

How Long Can I Keep Peanut Butter Blueberry Overnight Oats in the Refrigerator?

You can keep peanut butter blueberry overnight oats in the refrigerator for 2-3 days.

For longer term storage, do not add the blueberries, and store the overnight oats for up to 1 week. Add the blueberries just before serving.

Can I use Almond Butter Instead of Peanut Butter?

Yes, you can use almond butter instead of peanut butter. It’s a perfect alternative for those with peanut allergies.

You could also use other nut or seed butters if preferred.

Are There Gluten-Free Options for This Recipe?

This recipe is naturally gluten-free, so long as you make sure to choose certified gluten free oats.

While oats do not normally contain gluten, they are commonly processed on machinery that does, which can cause cross contamination for those highly sensitive.

Can I Add Protein Powder to Overnight Oats?

Yes, you can absolutely add protein powder to overnight oats. Add a single serving, or up to 2 tsp of your favorite.

Peanut butter flavor protein powder would go best here, but you can use vanilla as well.

Can I Make Peanut Butter Blueberry Overnight Oats with Steel-Cut Oats?

You can make peanut butter blueberry overnight oats with steel cut oats. However, steel cut oats are chewier and thicker than other varieties. The longer they sit, the softer they get, so they are a good choice for a big batch being stored for a week.

Otherwise, old fashioned or rolled oats are more popular choices for overnight oats. You should not use instant oats for this purpose.

Do Blueberries and Peanut Butter Go Well Together?

Yes, blueberries and peanut butter go well together. The flavor combination is akin to the classic peanut butter and jelly sandwich. In fact, most berries compliment peanut butter well.

This berry and nut butter combination is seen in all sorts of dishes, including sandwiches, smoothies, desserts, milkshakes, and overnight oats to name a few.

Recipe Pro Tips

  • For an elegant look for presentation, you can layer you overnight oats with a ribbon of peanut butter and more berries or jam in between (if you’re drinking them then it’s not worth it)
  • The liquid to oats ratio for overnight oats is generally between 1:1 and 2:1, depending how thick you like yours. For drinking, plan to double the liquid amount

Tips For Preparation and Storage

  • Overnight oats are designed to be made ahead for busy mornings. Simply combine your ingredients and store in the refrigerator until you’re ready to eat
  • With fresh fruit, overnight oats keep for 2-3 days in the refrigerator. For a larger batch, omit the fruit and add it when you’re ready to eat. This allows the oats to keep for up to one week!
  • If you would like to reheat overnight oats, add a serving to a microwave safe bowl and cook on high for about 1 minute. Stir and enjoy like a normal bowl of hot oatmeal!
