Cookie Dough Overnight Oats
These cookie dough overnight oats are the kind of breakfast that makes you feel like you’re getting away with something. Creamy, lightly sweet, packed with vanilla, nut butter, and mini chocolate chips, and somehow still totally appropriate to eat at 7 a.m.

They taste like actual cookie dough. Not “inspired by.” Not “close enough.” Real cookie dough vibes. But they’re made with wholesome ingredients, loaded with protein, and keep you full for hours. This is the breakfast I prep when I want mornings to feel easier and a little more fun.
If you love overnight oats but get bored of the same flavors, this one needs to be in your rotation.

What Makes These Taste Like Cookie Dough
A few key ingredients do the heavy lifting here.
Extra vanilla is non-negotiable. Cookie dough flavor comes from vanilla more than anything else.
Nut butter adds richness and that classic cookie dough base. Peanut butter or almond butter both work beautifully.
Greek yogurt gives these overnight oats a thick, creamy texture and adds protein.
Mini chocolate chips distribute evenly so you get chocolate in every bite.
It’s cozy, nostalgic, and genuinely satisfying.
Ingredients and Tips
Old-fashioned rolled oats hold their texture best for overnight oats. Quick oats will get too soft.
Vanilla Greek yogurt adds sweetness and protein without extra sugar.
Milk of choice loosens the mixture so the oats soften properly.
Chia seeds help thicken everything and add staying power.
Nut butter creates that cookie dough flavor and richness.
Maple syrup or honey sweetens just enough without being overpowering.
Sea salt balances the sweetness and enhances the cookie dough vibe.
Cinnamon is optional but adds warmth.
Texture Check Before Chilling
Before you refrigerate, the mixture should look like thick, pourable oatmeal.
- Too thick? Add a splash of milk
- Too thin? Add a spoonful of chia seeds or oats
Once chilled, it should be creamy, not soupy.
How to Make Cookie Dough Overnight Oats Foolproof
- Blend the wet ingredients until completely smooth
- Stir thoroughly so chia seeds don’t clump
- Fold in chocolate chips last
- Let them chill at least 6 hours
Overnight is ideal for the best texture.
Ingredient Swaps & Variations
- Use dairy-free yogurt and milk to make them dairy-free
- Swap peanut butter for almond butter or sunflower seed butter
- Add collagen or protein powder if you want more protein
- Use dark chocolate chips or chopped chocolate
- Add a spoonful of cottage cheese for extra creaminess
These oats are very forgiving.
Common Problems and Fixes
Oats too thick:
Stir in milk before eating.
Oats too thin:
Add more chia seeds and let them sit another hour.
Nut butter clumps:
Make sure it’s fully blended into the wet ingredients.
Not sweet enough:
Drizzle a little maple syrup on top before serving.
Storage & Reheating
This recipe is perfect for weekly meal prep.
- Portion into jars or containers
- Store in the fridge for up to 5 days
- Stir before eating
If they thicken too much after a few days, just add a splash of milk.

I have always been intimidated to make overnight oats but this was so easy! I used peanut butter, honey and a little cinnamon like you suggested. I added chopped dark chocolate and my husband loved his with sliced bananas. It was perfect for a busy morning and so delicious! Definitely in our rotation for a little treat!
