Ingredients
- 1 cup old-fashioned rolled oats
- 1 cup milk of your choice (dairy or non-dairy)
- 1/4 cup plain Greek yogurt
- 2 tablespoons almond butter or peanut butter
- 1 tablespoon chia seeds
- 1 1/2 tablespoons brown sugar or coconut sugar
- 1 teaspoon pure vanilla extract
- 1/4 teaspoon salt
- 3 tablespoons mini chocolate chips (plus more for topping)
Substitutions
- Rolled oats: You can use quick oats for a softer texture, but avoid instant oats since they turn mushy.
- Greek yogurt: Coconut yogurt or regular plain yogurt works great if you want a dairy-free option.
- Almond butter: Peanut butter, cashew butter, sunflower seed butter, or even tahini all work well here.
- Brown sugar: Maple syrup, honey, or a sugar-free sweetener like monk fruit can be used in equal amounts.
- Mini chocolate chips: Use dark chocolate chips, cacao nibs, or white chocolate chips depending on your preference.
- Milk: Oat milk, almond milk, soy milk, or regular whole milk all give great results.
How to Make Thick Cookie Dough Overnight Oats
- Grab your jar or container: A mason jar or any airtight container with a lid works perfectly. You want something that holds at least 16 ounces so there is plenty of room to stir.
- Add the dry ingredients first: Pour the rolled oats, chia seeds, brown sugar, and salt into your jar. Giving the dry ingredients a quick stir helps distribute everything evenly before you add the wet stuff.
- Mix in the wet ingredients: Add the milk, Greek yogurt, almond butter, and vanilla extract right on top of the dry ingredients. Stir everything together really well until the nut butter is fully mixed in and no clumps remain.
- Fold in the chocolate chips: Add your mini chocolate chips and give the mixture one last gentle stir. Save a few extra chips to sprinkle on top in the morning for a pretty finish.
- Check the consistency: The mixture might look a little thin at this point and that is completely normal. The oats and chia seeds absorb the liquid overnight and thicken everything up beautifully.
- Cover and refrigerate: Seal your jar tightly and place it in the fridge for at least 6 hours. Overnight is ideal and gives you the thickest, creamiest texture possible.
- Stir and enjoy: In the morning, give your oats a good stir. If they seem too thick, add a splash of milk and mix it in. Top with extra chocolate chips and dig in!
Pro Tips for Perfect Thick Cookie Dough Overnight Oats
- Use full-fat yogurt: Full-fat Greek yogurt adds richness and makes the oats noticeably thicker and creamier compared to low-fat versions.
- Do not skip the chia seeds: Chia seeds are the secret weapon for getting that super thick, pudding-like texture. They absorb liquid and expand as the oats sit overnight.
- Stir well before refrigerating: Make sure the almond butter is fully incorporated before you put the jar in the fridge. Clumps of nut butter can stay clumpy if not mixed in properly from the start.
- Let it sit a full 6 to 8 hours: The longer these oats chill, the better they taste. Trying to eat them after just 2 or 3 hours will give you a much thinner result.
- Adjust sweetness in the morning: Taste your oats before eating and add a little extra sweetener if needed. Sometimes the flavors mellow out overnight and a tiny drizzle of maple syrup brings it all together.
Flavor Variations
- Double Chocolate Cookie Dough: Add 1 tablespoon of unsweetened cocoa powder to the base mixture for a rich, brownie-like twist on the classic recipe.
- Peanut Butter Cookie Dough: Swap the almond butter for peanut butter, add a little extra brown sugar, and top with crushed peanuts for a PB cookie experience in a jar.
- Birthday Cake Cookie Dough: Use vanilla protein powder instead of yogurt, add rainbow sprinkles, and top with whipped cream for a festive and fun version.
- Oatmeal Raisin Cookie Dough: Skip the chocolate chips and add 3 tablespoons of plump raisins along with a pinch of cinnamon and nutmeg for a cozy fall flavor.
Storage Tips
These overnight oats stay fresh in the refrigerator for up to 5 days when stored in a sealed airtight container or mason jar. This makes them one of the best meal prep breakfasts you can make because you can prep a whole week’s worth on Sunday night and have breakfast ready every single morning.
For the best texture, keep the chocolate chip topping separate and add it right before eating so the chips do not get too soft. If your oats thicken up more than you like over a few days, just stir in a splash of milk to loosen them up to your preferred consistency.
You can also freeze overnight oats for up to 3 months. Pour them into a freezer-safe container, leaving a little room at the top for expansion. Thaw them overnight in the fridge and give them a good stir in the morning before eating. Keep in mind that frozen and thawed oats may be a bit softer in texture than freshly made ones.

Frequently Asked Questions
Can I make thick cookie dough overnight oats without yogurt?
Yes, you can leave out the yogurt and replace it with an equal amount of extra milk. The oats will still thicken up nicely thanks to the chia seeds, though the texture will be slightly less creamy than the original recipe. Adding a tablespoon of protein powder is also a great way to keep the protein content up if you skip the yogurt.
Why are my overnight oats not thick enough?
The most common reason overnight oats are too thin is not letting them sit long enough. You need at least 6 hours in the fridge for the oats and chia seeds to fully absorb the liquid. Also, make sure you used the right ratio of liquid to oats. Too much milk will result in thinner oats, so stick to the measurements in the recipe for the best thick texture.
Can I eat these oats warm?
Absolutely! If you prefer warm oats in the morning, simply transfer them to a microwave-safe bowl and heat in 30-second intervals, stirring in between, until they reach your desired temperature. Add a splash of milk before heating if needed since the oats thicken even more when warmed up. Just add the chocolate chips after heating so they do not fully melt.
Are these overnight oats gluten-free?
Oats are naturally gluten-free, but they are often processed in facilities that also handle wheat. To make this recipe certified gluten-free, look for oats that are specifically labeled as certified gluten-free on the packaging. All other ingredients in this recipe are naturally gluten-free as well.
How do I make these oats higher in protein?
To boost the protein content, you can add one scoop of your favorite vanilla or chocolate protein powder when mixing the ingredients. You can also increase the Greek yogurt to 1/2 cup or stir in an extra tablespoon of nut butter. Hemp seeds are another easy protein boost that blends right in without changing the flavor much.
These thick cookie dough overnight oats are about to become your new favorite breakfast obsession, and once you try them, you will wonder how you ever started your mornings any other way.
