Why Should You Make This Recipe

I love making overnight oats for a quick and easy, filling and protein filled breakfast. My Protein Overnight Oats, Apple Cinnamon Overnight Oats, Tiramisu Overnight Oats, Blueberry Overnight Oats and Pumpkin Overnight Oats are overnight oats recipes that I absolutely adore. This peanut butter overnight oats recipe is another healthy, protein packed breakfast recipe I know you will love just as much as I do. 

  • Quick and healthy breakfast. This peanut butter overnight oats recipe takes about 5 minutes to assemble using a handful of simple ingredients. Simply mix everything together and allow the oats to soak overnight. The result is a delicious, healthy and hearty breakfast. 
  • Perfect for meal prep. Peanut butter overnight oatmeal is perfect for making at the beginning of the week and enjoying for a healthy, filling and delicious breakfast for the next 3 - 4 days. 
  • You need an eggless, gluten free and filling breakfast idea. Oats are filled with fiber and slow digesting, complex carbs. Add chia seeds, milk, some sweetener and peanut butter and you’ve got a simple and filling breakfast that will keep you full all morning.

Ingredients

This overnight peanut butter oatmeal recipe requires only a handful of basic pantry ingredients which makes them perfect for busy mornings. Here’s what you will need.

Gather oats, chia seeds, milk, yogurt, peanut butter, maple syrup and vanilla extract. To top the oats like in the pictures, you will also need peanut butter, honey and mini chocolate chips.

Substitutions 

Here are my recommended substitutions to make this overnight oats with protein if you need them.

  • Oats: Heartier types of oats such as old fashioned, rolled oats or steel cut oats are better options for overnight oats. Quick cooking oats will become mushier than the other types of oats. If needed, use gluten free oats to make these overnight oatmeal gluten free. 
  • Chia Seeds: I like adding chia seeds to overnight oats for a thicker and creamier consistency. Feel free to omit or use flax seeds if you like. 
  • Milk: Use any milk you like. Plant based milk also works well in this recipe if you would like to make these protein overnight oats vegan. For an extra boost of protein, use protein milk. 
  • Yogurt: Use a good greek yogurt you like. If you would like to make this vegan, use a plant based yogurt. 
  • Peanut Butter: Feel free to use your preferred runny or creamy peanut butter. If you prefer not to use peanut butter, use any nut butter you like. Sunbutter is a good peanut butter alternative. 
  • Maple Syrup: Honey or agave work well to sweeten these protein oats. 
  • Vanilla Extract: This is for flavor. Feel free to omit if you don’t have any vanilla extract on hand.

How To Make

Learn how to make peanut butter overnight oats in a few easy steps.

  1. Grab 2 containers with lids to prepare the protein overnight oats recipe. To make a layered look, smear some peanut butter around the edge of the container. Add half of the oats and chia seeds into each container. Mix the chia seeds and oats together until well combined. 
  2. Add the milk, yogurt, peanut butter, maple syrup or honey and vanilla extract to a large mixing bowl. Whisk the mixture together until smooth and well combined.
  1. Evenly pour the peanut nutter mixture into each of the containers and mix gently well. Cover the containers and transfer the overnight pb oats to chill in the fridge for at least 4-6 hours or overnight.
  2. When it’s time to serve, top the peanut butter oats with your preferred toppings and enjoy. I love topping mine with warmed peanut butter, slices of bananas, a drizzle of honey and some mini chocolate chips.

How To Make Ahead, Store and Serve

  • Make Ahead: Peanut butter overnight oats are perfect for meal prep. Prepare the oats according to the recipe through to the chilling step. The oats will keep well in the fridge for up to 3 days. Wait to top the peanut butter overnight oatmeal until right before serving. 
  • Store: Place the overnight ob oats in an airtight container for up to 3  days in the fridge. 
  • Serve: Top the overnight peanut butter oats with your preferred toppings. I suggest a dollop of peanut butter, some sliced bananas or berries and a drizzle of honey.

M’s Expert Tips

  • Mix the ingredients directly into individual containers. The easiest and more precise way to make overnight oats is to mix the dry and wet ingredients directly into the individual containers. If you prefer, mix the dry ingredients in the containers. Then mix the liquid ingredients in a large bowl until well combined. Evenly pour the liquid into the containers and chill. 
  • How to make it pretty. To create the layered look simply smear some pb on the sides of the glass container prior to mixing in the overnight oats. 
  • Use the right kind of oats. Rolled oats, old fashioned oats or steel cut oats are good for making overnight oats. Quick cooking oats are not ideal unless you prefer a mushier texture. 
  • Add chia or flax seeds. The addition of chia or flax seeds adds healthy omega-3 fats and creates a thicker more pudding like consistency to the pb overnight oats. 
  • Add toppings right before serving. Add a dollop of peanut butter, some sliced bananas or berries and a drizzle of honey right before serving.

FAQs

Are peanut butter overnight oats healthy?

Yes, overnight oats have a whole host of benefits to keep your body healthy. Soaking the oats breaks down starches and phytic acid, making the nutrients and vitamins easier to absorb. The addition of chia seeds adds a boost of omega-3. Adding peanut butter or any other nut butter adds more satiating protein to keep you fuller for longer.

How to soften peanut butter for overnight oats?

Scoop the amount of peanut butter you would like to add to the overnight oats either as a mix-in or as a topping, to a microwave safe dish. Heat the peanut butter for about 20 - 30 seconds or until the pb becomes more liquid.
