Overnight oats are a classic, but have you ever tried adding protein powder to your oats?

Not only is this recipe delicious, but one (huge!) serving packs a whopping 28 grams of protein.

Add in some slivered almonds on top and you are easily over 30 grams of protein.

This breakfast recipe is also vegan, gluten free, and you can prep it in just 5 minutes!

Have I convinced you to try protein powder in your overnight oats yet?

Ingredients to make protein overnight oats

  • banana – mashed banana is perfect in overnight oats and adds a nice sweetness. I tested two versions of this recipe without banana, and the one with banana was the best tasting.
  • protein powder – you can use any protein powder you like. I used a plant based vanilla one, but chocolate would also be a good choice!
  • oats – old fashioned oats, also known as rolled oats
  • unsweetened almond milk – you can use any milk that you have on hand
  • peanut butter – because you just can’t go wrong with the classic combo of peanut butter + banana
  • maple syrup – the real stuff. This is the best natural sweetener for oats.
  • vanilla extract
  • chia seeds

How to make overnight oats

Step 1: mash the banana in a mason jar or bowl of choice.

Step 2: add the remaining ingredients – protein powder, milk, oats, maple syrup, peanut butter, vanilla extract, and chia seeds.

Stir it all up to combine.

Step 3: If you have a mason jar with lid, this is the best way to store overnight oats. Just screw the lid on the jar of oats and refrigerate overnight, or at least 4 hours.

The longer the oats sit, the softer they will be.

If you do not have a mason jar, just cover the oats with cling wrap.

These protein overnight oats will thicken up a lot in the fridge, and all the flavors will really combine.

We love making oats for a homemade breakfast that we can prep ahead for busy mornings.

What to put on overnight oats

The topping possibilities are endless! Some of our favorites include:

  • raspberries
  • blueberries
  • blackberries
  • strawberries
  • sliced banana
  • slivered almonds
  • walnuts

I tested three versions of overnight oats using protein powder, and this one was by far the most delicious!

This recipe is so filling and tastes amazing.

Whoa. This recipe is UN-REAL. I rely heavily on internet bloggers for recipes and have stumbled across some delightful ones, but I've never a comment. This was SO good, I had to come back and drop a note. Thank you for publishing this amazing concoction!! It will be staple in our house going forward. Simple, convenient, nutritious, satisfying, delicious!

Note: I made a few slight adaptations for food sensitivities (sunflower butter vs. peanut butter, and plain pumpkin protein powder vs. vanilla protein powder) and reduced the maple syrup to 1 tbsp. My husband made it more closely to spec but used chocolate protein powder and also reduced the maple syrup to 1 tbsp. We were both shocked at how good it was!!

Thank you so much!!
