Why I Love This Recipe
The first time I made this, I just wanted something different from plain oatmeal. I crushed up a few chocolate sandwich cookies, stirred them in, and hoped for the best. The next morning, I opened the fridge and took one bite… and it honestly tasted like dessert.
Now it’s one of my favorite make-ahead breakfasts because:
- It tastes like cookies and cream ice cream.
- It keeps me full for hours.
- It takes about 10 minutes to mix together.
- No cooking needed.
- It’s easy to double for the week.
It feels indulgent, but it’s simple and balanced.
What You’ll Need
- 1 cup old-fashioned rolled oats
- 1 cup milk (dairy or unsweetened almond milk)
- 1/2 cup plain Greek yogurt
- 1 tablespoon chia seeds
- 1 tablespoon maple syrup
- 1/2 teaspoon vanilla extract
- 4 chocolate sandwich cookies, crushed
- 1 tablespoon dark chocolate chips (optional, for topping)

Tools You’ll Need
- Medium mixing bowl
- Spoon or spatula
- Measuring cups and spoons
- 2 jars or containers with lids
- Small microwave-safe bowl (for melting chocolate, optional)
Recipe Instructions
Step 1: Mix the Base
In a medium bowl, add 1 cup rolled oats, 1 cup milk, 1/2 cup plain Greek yogurt, 1 tablespoon chia seeds, 1 tablespoon maple syrup, and 1/2 teaspoon vanilla extract. Stir well until everything is fully combined and creamy.

Step 2: Crush and Add the Cookies
Take 4 chocolate sandwich cookies and crush them into small chunks. Stir the crushed cookies into the oat mixture so they’re evenly spread out.

Step 3: Portion and Chill
Divide the mixture evenly into 2 jars. Seal with lids and place in the fridge for at least 4 hours, or overnight, until thick and set.

Step 4: Add Topping Before Serving
If using, melt 1 tablespoon dark chocolate chips in a small microwave-safe bowl until smooth. Drizzle the melted chocolate over the chilled oats and sprinkle extra crushed cookies on top before serving.

Pro Tips
- Stir really well in Step 1 so the chia seeds don’t clump.
- Let it chill at least 4 hours. Overnight is even better.
- Crush cookies into chunks, not powder. You want texture.
- If it’s too thick in the morning, add a splash of milk and stir.
Substitutions and Variations
- Use chocolate Greek yogurt for extra chocolate flavor.
- Swap maple syrup for honey.
- Use gluten-free sandwich cookies if needed.
- Add a spoon of cocoa powder for deeper chocolate taste.
- Stir in protein powder for a protein boost.
Make Ahead Tips
These stay fresh in the fridge for up to 4 days. Make a double batch and portion into jars for the week.
Leftovers and Storage
Store in airtight jars in the fridge for up to 4 days. If they thicken too much, stir in 1–2 tablespoons milk before eating. Do not freeze, as the texture will change.

Why This Recipe Works (Quick Science)
Chia seeds absorb liquid and expand, helping thicken the oats. Greek yogurt adds protein and creaminess. As the oats soak overnight, they soften without cooking. The crushed cookies release flavor into the milk, giving that cookies-and-cream taste all the way through.
Common Mistakes
- Not stirring enough: This causes dry oat pockets.
- Skipping chill time: It won’t thicken properly.
- Adding too many cookies: It can overpower the oats.
- Using quick oats: They can get too mushy.
What to Serve With
- Fresh strawberries or raspberries
- A banana on the side
- A boiled egg for extra protein
- Iced coffee or a smoothie
