Have you wondered what all the fuss is about overnight oats–because they kind of seem like a cold bowl of oatmeal that someone forgot on the counter?
Me too. But then I tried them at a resort while on vacation–and there’s nothing like someone else making you breakfast (and eating it by the ocean) to change your mind!
This variation is a mash-up of overnight oats and my all-time favorite cookie: No Bakes.

Ingredients You Need
- Old-Fashioned Oats: These give the best texture.
- Powdered peanut butter: This ingredient gives the flavor of peanut butter without the fat and with fewer calories. It’s shelf-stable, and you can usually find it at the store alongside the peanut butter. It comes in sweetened and unsweetened versions–either works. If you’d rather use regular peanut butter, you can.
- Cocoa powder
- Cacao nibs or mini chocolate chips: I prefer cacao nibs here to give a chocolate flavor without sugar, but feel free to use regular chips and reduce the maple syrup.
- Pure maple syrup: You can use honey here as well. Adjust the amount based on how sweet you like it.
- Vanilla extract
- Milk: Use what you have and like, whether it’s dairy or plant-based milk.

- In the morning, give it a stir and add a splash of milk if it’s thicker than you like.
- Top with a drizzle of peanut butter and a few cacao nibs or chocolate chips if you’re feeling fancy, and dig in!

Variations You Might Like
- Add a scoop of protein powder for even more staying power (cut back on the maple syrup if it’s sweetened).
- Try regular peanut butter instead of powdered peanut butter. The texture will be creamier.
- Use almond butter or sunflower seed butter if you want a peanut-free version.
- Swap maple syrup for honey if that’s your preference.

Questions About No Bake Cookie Overnight Oats
Are overnight oats healthy?
Yes! Oats are whole grain and rich in heart-healthy soluble fiber, which may help to reduce your cholesterol level and is good for gut health. They also provide protein–this recipe has 19 grams of protein.
Are you supposed to eat overnight oats cold or warm?
Either works. Most people eat them cold, straight from the fridge. But feel free to warm them in the microwave.
Can I prep overnight oats ahead of time?
Absolutely. You can double, triple, or quadruple this recipe to prep overnight oats for multiple days. Keep in mind that they’ll thicken the longer they sit in the refrigerator, so you’ll want to add more milk before eating.
