Ingredients for Spooky Oreo Overnight Oats

  • Oats
  • Milk or milk alternative
  • Cocoa powder
  • Oreo pudding mix or chocolate
  • Oreos
  • Peanut or almond butter
  • Gummy worms for topping
  • Optional: flax meal, chia seeds, or hemp hearts

Learn How to Make It

Overnight oats are incredibly easy to make and this Oreo oatmeal take on them will show you that you can literally add anything to them. All of the ingredients get added to a container. I recommend a glass container so that you can heat them up in the morning if desired.

Stir the ingredients together well or blend them ahead of time if desired (see below). Place them in the fridge the night before and when you wake up, breakfast is ready to go.

Cooking Shortcuts

Technically overnight oats take a long time because the oats absorb all of the liquid over a span of about eight to ten hours. If you want to fast track this recipe, the shortcut is to add all of the ingredients to a microwave safe bowl. Next, microwave them for two to three minutes, stopping and stirring every minute.

Nutrition Boosts

You’ll see a lot of my oatmeal recipes suggest boosting the nutrition with ingredients like hemp hearts, chia seeds, plain protein powder or flax meal. That’s because I like to focus on adding nutrients in, instead of restricting them. This is not necessary for every meal!

It’s important to ask yourself why you’re adding these nutrients so there’s a purpose behind them. They could be helpful in keeping you fuller longer or helping you meet your fiber goals. Or perhaps you’re not eating enough protein, then adding the plain powder could be helpful.


Can You Blend Overnight Oats

Yes, blended overnight oats end up having a cookie dough like texture. For this recipe in particular, I blended all of the ingredients except for the Oreo cookies. I crumbled them and stirred them in afterwards for texture.

Can You Freeze Overnight Oats

Great question! Yes, you can totally freeze overnight oats and oatmeal in general. I recommend making them and allowing the oats to absorb all of the liquid overnight before freezing them.

They’ll stay good for up to three months and easily thaw by placing them back in the fridge the night before you want to eat them. Add a little milk for extra moisture as needed.

I also love to make large batches of oatmeal in the crockpot like this Berry Oatmeal recipe and freeze them in individual portions using a muffin baking tray.

They take about three hours to freeze in a muffin tray. Once frozen, take them out of the tray and plop them in a gallon size Stasher bag or regular freezer bag. Thaw them by heating them in the microwave, adding a little milk for more moisture.

Benefits of Overnight Oats

As a culinary registered dietitian, I can tell you that overnight oats are full of opportunities for flavor and nutrition. Overnight oats one of the easiest breakfast meals to prep to load up on whole grains, quality fats, vitamins, minerals and protein.

There are a ton of options out there like these Peach Overnight Oats or Cherry and Peanut Butter Overnight Oats. Try any variety because increasing the variety of foods we cook (and eat) is a path toward better nutritional intake overall.

I recommend they be made in an air tight container (glass if you’re planning to reheat them) and stored in the fridge for up to five days. As stated above, you can make overnight oats and freeze them for up to three months. This is a great option if you prepped too many and want to switch your breakfast up one morning.
