If this is your first time making Overnight Oats, don’t stress. This recipe is impossible to mess up. Plus you get that satisfying chocolate flavor while filling peanut butter keeps you going all day. Win-win!

Ingredients

  • Oats. Old-fashioned oats will get you a better texture, but quick oats can also be used. However, use less milk, and they might end up a but mushier. Definitely avoid steel-cut oats.
  • Milk. You can use a regular or a plant-based alternative. Oat milk is my favorite! Feel free to go with soy, almond, or cashew milk for vegan oatmeal. My favorite type of milk to use when making overnight oats is almond milk.  It is subtle enough in flavor, while still having the consistency of regular milk. Avoid coconut milk if possible as it adds quite a bit of flavor to the dish.
  • Cocoa powder. Be sure to go with an unsweetened variety. Depending on your personal preference, choose regular or dark. 
  • Peanut butter. Either creamy or crunchy peanut butter are fine—opt for your personal preference. If needed, you can also sub with almond or cashew butter.
  • Sweetener. Keep it natural with pure maple syrup, honey, or agave nectar. Sweeten it to preference.

How to Make Chocolate Peanut Butter Overnight Oats

Please see the recipe card below for more detailed ingredient amounts.

1. Combine Ingredients

Add the oats and cocoa powder to a large bowl. Use a whisk to thoroughly combine.

Carefully stir in the milk of choice, maple syrup, and vanilla extract. Be sure no lumps are remaining for the best results.

2. Pour into Jars

Be sure to use 8-ounce jars when making this recipe. They are easy to find and perfectly fit one serving of overnight oats.

Evenly divide the oat mixture between 4 jars. Add one tablespoon of the peanut butter to the top of the oatmeal.

3. Chill in the Fridge

Place a lid on each jar, ensuring it is screwed on tight. Set the jars in the fridge.

Let the oatmeal set up for at least 2 hours in the fridge. But, it will be best if left to chill overnight.

Before digging in, top with some chopped peanuts. You can even include some chocolate chips or any other favorite toppings, as well.

What are Overnight Oats?

Overnight oats are old-fashioned or quick-cooking oats that absorb some sort of milk (almond, soy, coconut, cashew, or regular milk) for at least two hours. This is an easy breakfast that is incredibly versatile.

You can choose to mix in your toppings before the overnight oats are refrigerated or after. Crunchy toppings such as nuts taste best if added the day of serving, whereas soft toppings, like peanut butter, will do well if refrigerated.

How Long Do Overnight Oats Last?

Overnight oats are best enjoyed within the first 24 hours but will last for up to 2-3 days if refrigerated properly. However, the texture does start to get a bit thick after the first day or two.

    1. Yes, Zach! That’s totally it. I like to use unrefined sugars whenever possible. You can always use regular sugar if that’s what you have!

    1. What a wonderful idea, Stefanie!! Do you have a favorite brand of hemp hearts? I have not tried those yet and would love to add them to some overnight oats next time, too!

    1. Hi Faith! Yes, the nutrition facts are for 1 serving (or 1/4 of the total amount.) Peanut butter and peanuts are pretty calorically dense so you can always decrease how much you use or leave off the peanuts entirely to decrease the calories.
