Cookie Dough Overnight Oats are a fun, tasty twist on your regular morning oats. They mix creamy oats with a bit of sweet vanilla and a sprinkle of chocolate chips, giving you that beloved cookie dough flavor without having to bake anything. It’s like having a little dessert and a healthy breakfast all in one bowl!
I love making these the night before because they’re so easy—just stir everything together, pop it in the fridge, and in the morning it’s ready to eat. I usually add a pinch of cinnamon or a few nuts for a little extra crunch, which makes the oats even better. It’s my go-to when I want a quick breakfast but don’t want to skip on flavor or fun.
These oats are great on their own or topped with fresh fruit like sliced bananas or strawberries. Sometimes I even swirl in a spoonful of peanut butter to make it richer. They’re perfect for busy mornings or when you want something sweet but still want to start the day on a good note. I know I keep coming back to this one because it’s easy, filling, and feels like a treat every time!
Key Ingredients & Substitutions
Rolled Oats: These give the oats a nice chewy texture after soaking. Avoid instant oats here, as they get too mushy. Steel-cut oats won’t soften enough overnight.
Milk: Dairy milk or any plant milk works! Almond, oat, or soy milks all add a different flavor, so pick your favorite. Thicker milks make the oats creamier.
Greek Yogurt: Adds creaminess and protein. Use dairy-free yogurt if you prefer vegan or dairy-free.
Chia Seeds: These help thicken the oats and add some fiber. If you don’t have chia seeds, you can skip them, but the texture may be looser.
Maple Syrup or Honey: Sweetens the oats naturally. For a vegan option, use maple syrup or agave.
Vanilla Extract: This little touch makes the flavors pop and gives the cookie dough vibe.
Peanut Butter: The creamy topping adds richness and pairs perfectly with chocolate. You can swap it for almond butter or sunflower seed butter if you want.
Chocolate Chips: Mini dark chocolate chips or chunks are best for that cookie dough feel. You can also use semi-sweet or dairy-free chocolate chips.
How Do You Get Perfectly Creamy Overnight Oats Without Them Being Too Runny or Thick?
Balancing the texture is key for overnight oats. Here’s how to make them just right:
- Measure liquids carefully. Equal parts oats and liquid usually work well, but if you prefer thicker oats, reduce liquid a little.
- Add yogurt for creaminess. Yogurt thickens the oats and keeps them rich, so don’t skip it if you want creamier oats.
- Don’t stir too hard before chilling. Mix just enough to combine ingredients, then let the oats absorb moisture overnight.
- Use chia seeds to thicken. They soak up liquid and add a nice texture without clumping.
- Check after 6 hours. If the oats look too thick, stir in a splash of milk before serving. If too runny, add a spoonful of oats or chia seeds and let sit for a little longer.
Following these tips will help you get that creamy, soft, yet thick oats texture that makes overnight oats so enjoyable.
Equipment You’ll Need

Step-by-Step Instructions:
1. Mix the Ingredients:
In a medium bowl or jar, add your rolled oats, milk, Greek yogurt, chia seeds, maple syrup or honey, vanilla extract, and a pinch of salt. Stir everything well until it’s fully combined.
2. Refrigerate Overnight:
Cover your bowl or jar with a lid or plastic wrap and place it in the fridge overnight, or for at least 6 hours. This lets the oats absorb the liquids and become yummy and creamy.
3. Add Peanut Butter and Chocolate:
Before you dig in, give the oats a gentle stir. If you like, swirl in a tablespoon of peanut butter for extra creaminess. Then spoon the oats into your favorite jar or bowl. Top with the rest of the peanut butter and sprinkle on the dark chocolate chunks or chips.
4. Serve and Enjoy:
If you want, add a little extra crunch with some more oats or chocolate on top. Eat your cookie dough overnight oats cold straight from the jar or bowl—a delicious and easy start to your day!
Can I Use Frozen Fruit in My Overnight Oats?
Absolutely! Just add frozen fruit like berries or banana slices directly to the oats before refrigerating. They’ll thaw overnight and add a refreshing burst of flavor.
Can I Make This Recipe Ahead for Several Days?
Yes! You can prepare several jars at once and store them in the fridge for up to 4 days. Just keep the chocolate chips separate until serving to prevent melting.
What’s the Best Milk Alternative for Creamy Overnight Oats?
Oat milk and almond milk are great choices for creaminess and mild flavor, but feel free to use any plant-based milk you prefer. Higher-fat options usually make the oats richer.
How Can I Thicken My Overnight Oats if They’re Too Runny?
Add a bit more chia seeds or reduce the milk slightly next time. You can also stir in extra oats just before serving and let them sit a few minutes to absorb any excess liquid.
