Peanut Butter Overnight Oats with Oat Milk

Peanut Butter Overnight Oats with Oat Milk

With 15 grams of protein and 11 grams of fiber these peanut butter overnight oats made with oat milk are a filling way to start your morning! 

After years of adjusting the recipe, I’m officially in love with these creamy peanut butter overnight oats made with oat milk.

Despite making these oats nearly every day for the past 4 or so years, I feel like every year or so I find a small tweak that makes them even better.

In this case it’s been a three small tweaks, one of which was intentional while the other two were out of my control.

Tweaks I made to make these peanut butter overnight oats even better

  • Oat milk instead of almond. As I talked about in a previous post, almond milk is placing a strain on the environment due to the amount of water needed to grow them. Now I’m hooked on it’s nutty, slightly sweet flavor – especially in overnight oats!
  • Chewier, good-quality oats. While I used to buy 10 lb bags of Quaker Oats, I started trying out different brands and realized how much better these oats could be. Keep reading for my new go-to brand!
  • Less Greek yogurt. Initially not intentional (I was just running low on yogurt), but ever since I’ve preferred my overnight oats with less yogurt as they’re now chewier and less thick.

What You’ll Need to Make Peanut Butter Overnight Oats

  • Rolled oats
  • Chia seeds
  • Cinnamon
  • Natural peanut butter
  • Plain Greek yogurt
  • Original oat milk (unsweetened) 

Best oats for overnight oats

As mentioned above, I could have never guessed how the brand of oats can really make a difference. 

I’ve been loving Bob’s Red Mill Organic Rolled Oats.

Not only can you buy them in bulk (hello money-saver!), but they’re also chewier and have a sweeter, oatier taste than the Quaker oats I had been buying. 

If you like a little texture to your oats, it’s definitely worth finding a brand with thicker, higher quality oats.

How to adjust the consistency of your overnight oats

If you’re new to overnight oats, it can take a couple tries to get the consistency just to your liking.

This recipe makes a pretty thick jar of oats, which I love but I know may be too filling for others. 

Adjustments to try for thinner oats: 

  • Add an extra 1-3 tablespoons of milk in the morning
  • Leave out the chia seeds
  • Nix the Greek yogurt (although, the protein content will go down)
  • Use regular instead of Greek yogurt (again, the protein content will be slightly lower) 

Want these oats even thicker and more filling? Here are some adjustments to try: 

  • Use full-fat Greek yogurt
  • Use an extra tablespoon or two of Greek yogurt
  • Add an extra ½ – 1 tablespoon of peanut butter
  • Try an extra couple tablespoons of rolled oats 

Finally, while I prefer oats cold, I know some prefer them heated up. To do this, just leave out the yogurt when making them, heat them in the morning, and then stir in Greek yogurt afterwards. 

Benefits of using oat milk 

With so many types of milk and milk alternatives on the market, it can be confusing deciding what to buy.

Unfortunately the “right” answer really depends on individual nutrition needs, including allergies, intolerances, food preferences, nutrition goals (weight loss vs gain or maintenance), and — perhaps most importantly — personal preference. 

While oat milk isn’t the lowest calorie or highest protein option out there, it’s become my new go-to as I love the thicker texture and oaty, almost nutty, flavor.

It’s also better for the environment than almond (although I fully admit to still using almond milk occasionally), and the unsweetened version of oat milk (in my opinion) tastes better than any other unflavored milk alternative that I’ve tried. 

Plus, if you enjoy making alternative milks at home, oat milk is much cheaper and easier to make than a nut-based one.

Best way to stir overnight oats 

If you’ve looked at any of my overnight oat recipes before, you’ll notice that I always call for mixing with a butter knife rather than a spoon. 

Another trick that I discovered simply by chance, a butter knife does a much better job at evenly mixing all the ingredients together — which is super important when using chia seeds as no one wants to bite into a big clump of them.
