Key Ingredients And Swaps
- Large flake oats: Also known as rolled oats or old fashioned oats — these are my favorite to use in overnight oats because they absorb liquid while keeping some chew. You can swap for quick oats if needed, but instant or steel cut won’t work.
- Vanilla protein powder: It’s important you use flavored protein powder, not unflavored. My favorite for overnight oats is the vanilla whey protein from Leanfit, which we get at Costco.
- Powdered peanut butter: I like using powdered peanut butter instead of regular here because it has fewer calories, more protein, and more flavor. Don’t worry, you’ll add regular creamy peanut butter as a topping later.
- Ground flaxseed: A star ingredient for these cookie dough oats because they taste nutty and delicious, and offer some healthy fats. I get mine from Costco.

How To Make
Step 1: Add all ingredients to a jar.
Step 2: Stir, cover, and refrigerate overnight. Add toppings right before eating.
Topping Suggestions
I like to top these overnight oats with a big scoop of natural peanut butter and some mini chocolate chips. You could also try:
- Crushed nuts: 1-2 tablespoons of chopped peanuts, walnuts, pecans, or cashews.
- Seeds: A few teaspoons of hemp hearts or chia seeds add nice crunch.
- Another nut nutter: If you don’t love peanut butter, try cashew butter, almond butter, or any seed butter.
- Fresh or frozen fruit: Add 1/2 a sliced banana or 1/2 cup mixed berries.
- Dried fruit: Skip the chocolate and swap for a few tablespoons of dried fruit like raisins, dried cranberries, chopped dates, or diced apricots.
- More fun stuff: Swap chocolate chips for a tablespoon of chopped dark chocolate, granola, jam, or nutella.
Common Questions
Cookie dough overnight oats will stay good in the fridge for up to four days. Just make sure you stir them thoroughly before chilling.
You can substitute ground flaxseed for whole chia seeds, but they don’t taste as good here.
Make these overnight oats dairy-free by using plant-based protein powder, a plant-based milk alternative like soy or almond, and swapping the yogurt for extra milk.

Hi Miranda! Is the powdered peanut butter for texture? Could we use regular?
Love your recipes btw!
It’s for flavor! I use powdered here because it’s a bit more of a concentrated peanut flavor, and contains more protein vs fat from a nutritional perspective. But you can absolutely use regular if that’s preferred or that’s all you have. Hope you enjoy!!
