This recipe was actually the first time I ever made overnight oats. And boy was I impressed. They came out so creamy, luxurious and flavorful! I’ve been making them ever since, including these Pumpkin Spice Overnight Oats for fall and these Superfood Overnight Oats: Maca, Cacao, + Chia Seeds for detox.

How to Make the Best Peanut Butter Overnight Oats

The secret to the creamiest and sweetest overnight oats without tons of added sugar is to use a nice ripe banana. It should have some brown spots on the peel and be nice and soft. When you mash it up, the fruit gets even sweeter!

Ingredient Subs & Swaps

This is a very forgiving oatmeal recipe, so here are some simple ways to mix up the ingredients using what’s in your pantry. 

  • Oats. I highly recommend using thick-cut rolled oats, which absorb flavors well but don’t turn to total mush overnight. However, if you only have rolled or quick oats, you can still make this recipe with them. Quick oats will become quite soft if left to soak overnight though. 
  • Almond milk. Use any dairy-free milk you like. 
  • Peanut butter. You can easily ymake these banana overnight oats with almond butter, pistachio butter or even sunflower seed butter to make it nut-free. 
  • Agave. I like this vegan liquid sweeter, but other options like date syrup, coconut sugar or maple syrup also work. 
  • Cinnamon, nutmeg and allspice. You can also use pumpkin pie spice!

Health Benefits of Oats

Oats, especially rolled oats, are super nutritious! They include slow-burning carbs, soluble fiber, protein, and fat. In addition, they are loaded with important vitamins, minerals, and antioxidants.

Here are a few reasons to eat more oatmeal

  • They can help lower cholesterol.
  • Balance blood sugar levels, to prevent cravings or crashes. 
  • May help with losing weight because of the high fiber content.
  • Can help reduce inflammation in the skin.
  • Helps to relieve constipation.
