Cookie Dough Overnight Oats are a fun and delicious twist on classic overnight oats, combining creamy oats with the sweet, nostalgic flavors of cookie dough. With a touch of vanilla, a hint of brown sugar or maple syrup, and those little chocolate chips mixed in, it’s like having a breakfast treat that tastes like dessert. The oats soak overnight to get perfectly soft and creamy, making your morning so easy and tasty.
I love making these on busy mornings because they come together with just a few simple ingredients and you don’t have to cook anything. Plus, the chocolate chips add a nice little surprise with every bite. Sometimes I like to add a sprinkle of cinnamon or a pinch of salt to bring out all the flavors even more. It’s such a cozy way to start the day, and it feels like a small moment of happiness before the day really begins.
My favorite way to enjoy these overnight oats is straight from the fridge with a dollop of Greek yogurt on top and some fresh berries when they’re in season. They’re perfect for a quick breakfast on the go or even as a cool snack in the afternoon. If you’ve ever loved cookie dough, this is a great way to enjoy that flavor without any guilt and with the added bonus of healthy oats. I promise, it’s a make-ahead breakfast you’ll want to keep coming back to!
Key Ingredients & Substitutions
- Rolled oats
- These soak up the liquid nicely and get soft without becoming mushy. If you don’t have rolled oats, old-fashioned oats work well too. Avoid quick oats—they can get too mushy.
- Milk
- I usually use cow’s milk for creaminess, but almond, oat, or soy milk are great dairy-free options. Just pick what you like or have on hand.
- Greek yogurt
- Adds a creamy texture and protein. If you want it dairy-free, try coconut or almond milk yogurt. Regular yogurt works fine too.
- Peanut butter
- This gives that cookie dough flavor and thickness. You can switch it with almond butter, cashew butter, or sunflower seed butter for different tastes or allergies.
- Chocolate chips
- Mini chips mix evenly through the oats. Use dairy-free or vegan chocolate chips if needed. You can also chop up a chocolate bar.
How Do You Get the Perfect Creamy Texture in Overnight Oats?
The key to creamy overnight oats is the soaking time and the right liquid-to-oats ratio. Here’s what helps:
- Use rolled oats and enough milk (about equal parts oats to liquid) so they soften well without being runny.
- Mix in yogurt for a thicker, creamier feel and some tang.
- Let the oats sit covered in the fridge for at least 6 hours—overnight is best.
- Stir gently in the morning to combine all layers smoothly.
Adding a little salt balances sweetness and helps bring out the flavors. A swirl of peanut butter on top adds richness and texture that feels just like cookie dough.
Equipment You’ll Need
- Mason jar or airtight container – perfect for mixing and storing your oats overnight in the fridge.
- Mixing bowl – makes it easy to combine all ingredients evenly before layering.
- Measuring cups and spoons – helps keep your proportions just right for creamy oats.
- Spoon or spatula – for stirring the mixture and layering peanut butter smoothly.
Flavor Variations & Add-Ins
- Swap peanut butter for almond or cashew butter to change the nutty flavor and keep it allergy-friendly.
- Add mashed banana for extra natural sweetness and a creamier texture.
- Stir in cinnamon or a pinch of nutmeg to warm up the flavor and add a cozy twist.
- Top with fresh berries or sliced strawberries in the morning for a refreshing burst of color and taste.

- 1 tablespoon maple syrup or honey
- ¼ teaspoon vanilla extract

How Much Time Will You Need?

Step-by-Step Instructions:
1. Make Your Peanut Butter Layers:
Start by spooning 1 tablespoon of peanut butter into the bottom of a clean jar or bowl. This will give a tasty base layer that feels just like cookie dough.
2. Mix the Oat Mixture:
In a mixing bowl, combine the rolled oats, milk, yogurt, maple syrup, vanilla extract, and a pinch of salt. Stir everything well until you have a creamy, smooth mixture. Then fold in 1 tablespoon of the mini chocolate chips.
3. Layer the Oats:
Pour the oat mixture over the peanut butter layer in your jar. Spread or swirl the remaining tablespoon of peanut butter on top to make it extra creamy and delicious. Finish by sprinkling the last tablespoon of chocolate chips on the very top.
4. Chill and Enjoy:
Cover your jar or bowl and refrigerate overnight, or for at least 6 hours. When you’re ready to eat, give it a gentle stir and enjoy cold straight from the container. You can add extra peanut butter, fresh fruit, or a drizzle of honey if you want a little something extra.
Can I Use Frozen Fruit in Cookie Dough Overnight Oats?
Yes, you can add frozen fruit like berries or bananas, but it’s best to thaw them slightly beforehand to avoid excess moisture making the oats too watery. Just stir them in before serving.
Can I Make Cookie Dough Overnight Oats Without Peanut Butter?
Absolutely! You can replace peanut butter with almond butter, cashew butter, or even sunflower seed butter. If you prefer, you can skip the nut butter, though it adds to the creamy texture and flavor.
How Long Do Overnight Oats Last in the Fridge?
Stored in an airtight container, these oats keep well for up to 3 days. Beyond that, the texture might change and oats can become too soft, so it’s best to enjoy them within that timeframe.
Can I Use Quick Oats Instead of Rolled Oats?
While quick oats can be used in a pinch, they tend to become mushier and lose that hearty texture. Rolled oats are ideal for the best creamy but slightly chewy overnight oats.
