Peanut Butter Overnight Oats

Overnight oats are such an easy way to start your day with wholesome ingredients. They are so easy to mix in flavors with. From blueberry overnight oats to strawberry cheesecake oats to carrot cake overnight oats, there are so many fun flavors to try!

This peanut butter oat recipe is no exception! One of the best things about these oats is that they are easy to prepare.

All you need to do is mix the ingredients in a bowl and store them covered overnight. The next morning the rolled oats will have all the liquid and create the perfect creamy texture.

One of the most popular ways to store overnight oats is in a mason jar. The oats can be sealed tightly with a lid, preserving their freshness.

This is a great way to meal prep a bunch of overnight oats for breakfast throughout the week. Then when you’re ready to eat them, just give them a good stir and add any toppings you’d like.

Chopped nuts or seeds can add a nice crunch. You can even use crunchy peanut butter for this! Adding a dollop of strawberry jam on top gives a bit of that PB & J experience.

There are plenty of other overnight oat healthy recipes to try, like carrot cake overnight oats, banana bread oats, decadent chocolate oats, lemon blueberry overnight oats, rich and creamy strawberry cheesecake oats, classic peanut butter overnight oats, and warming apple cinnamon oats. It comes down to personal preference and variety.

Recipe Ingredients

To make delicious carrot cake overnight oats, you will need the following ingredients. Here’s an overview with the full instructions in the recipe card at the bottom of this post.

  • PEANUT BUTTER – You can use your favorite style of peanut butter. Crunchy peanut butter, natural peanut butter, creamy peanut butter, or nut butter will all work!
  • ROLLED OATS – Rolled oats work best, these are large flake oats and they absorb the moisture from milk and yogurt beautifully.
  • MILK – You can use any milk of your choice, such as dairy-free coconut milk, regular milk, oat milk, or unsweetened almond milk.
  • YOGURT – Yogurt adds creaminess and tanginess to the oats. You can use plain Greek yogurt or regular yogurt. If you don’t have yogurt, you can use extra milk instead.
  • HONEY – Liquid honey works great as a sweetener. Feel free to swap with pure maple syrup, brown sugar, or coconut sugar.
  • CHIA SEEDS – These add a gel-like texture to the oats and are a great source of fiber. If you don’t have chia seeds, you can use ground flaxseeds or just skip them altogether. They aren’t required.
  • SALT – This brings out the flavors of the other ingredients and balances the sweetness.


  • CHOCOLATE – Make chocolate peanut butter oats by adding cocoa powder or chocolate chips to the mixture.
  • BANANA SLICES – Bananas and peanut butter always go well together.
  • FRESH BERRIES – Adding fresh fruit like raspberries, blueberries, or strawberries always tastes good with everything.
  • CHOPPED PEANUTS – Chopped peanuts will add a nice crunch which can go really well with the soft and creamy texture of the overnight oats.
  • SHREDDED COCONUT – Sprinkle some coconut flakes into the oats before you mix, or add on top for a twist.
  • NUT BUTTER – Using your favorite nut butter instead of peanut butter will also work! You can try almond butter, peanut butter, or cashew butter.

Can I Use Quick Oats or Steel Cut Oats?

Yes, you can use either quick oats or steel-cut oats, but the texture will be different. Steel-cut oats will create a dense and chewy texture that isn’t a personal favorite.

Quick oats do not hold their structure as well and can produce a more mushy texture. I prefer old-fashioned rolled oats because they are in between both of these texture-wise.

How to Make Peanut Butter Overnight Oats

Overnight oats are so easy and simple to make. Here’s a quick overview with full details in the recipe card at the bottom of this post:

  1. ASSEMBLE – In a mason jar or other container with a lid, combine the rolled oats, milk, yogurt, peanut butter, honey, chia seeds, and salt. Stir well to combine.
  2. CHILL – Cover the container and place it in the fridge overnight to let the oats soak up all the liquid.
  3. SERVE – In the morning, remove the jar from the refrigerator and stir together. Add your favorite toppings like chopped nuts, warmed peanut butter drizzled on top, and a dollop of jam.

How long do you soak overnight oats?

You should soak them for at least 6-8 hours, but preferably overnight. This will give the rolled oats enough time to absorb as much liquid as possible, which will soften them. Make sure to store them in the fridge while they are soaking.

How To Store Oats

  • REFRIGERATE – Store the oats in an airtight container in the fridge for up to 5 days. My personal favorite container to use is a mason jar.
  • SERVING LEFTOVERS: Simply give the creamy oats a stir before serving to redistribute any liquid that may have separated. Add any desired toppings and serve.

Just grab one in the morning and give it a good stir. Add your favorite toppings like chopped nuts, a dollop of jam, chocolate chips, or a drizzle of peanut butter. They’re healthy and will keep you feeling full and satisfied all morning long.
