My family is obsessed with overnight oats, and these Chocolate Overnight Oats are the ultimate go-to in our house. They’re ridiculously easy to make, totally kid-approved, and the perfect way to kick off the day with something delicious.

As a mom of three, I’m all about simple, 7-ingredient recipes, and this one checks every box. No fuss, no fancy ingredients—just a quick, make-ahead breakfast that you can prep in minutes. Chances are, you already have everything you need in your pantry!

I love starting the morning with something quick, yet filling, and this oatmeal recipe makes that so easy. While some people lean toward fruity flavors (hello, mango overnight oats and blueberry overnight oats), I’m all about chocolate (looking at you, chocolate smoothie). The best part? Everyone can customize their oats just the way they like them!

Ingredients

ingredients for chocolate overnight oats
  • Yogurt: I love using Greek yogurt for its thick, creamy texture, but any yogurt you like will work, even dairy free options.
  • Oats: Old-fashioned rolled oats are the best choice here—quick oats get too mushy!
  • Milk: Any kind you like! Want to double down on the chocolate? Try Trader Joe’s Chocolate Oat Milk or your favorite chocolate-flavored milk alternative.
  • Chocolate Syrup: I usually go for my homemade version, but you can swap in cocoa powder and a bit of maple syrup for a lower-sugar option. Or skip the chocolate syrup all together and just use the chocolate milk.

Step-by-Step Directions

Set up your jars. Find your lids before you start—nothing’s worse than making a batch and realizing you're missing that last lid!

Helpful tools

I don’t always need special tools, but when I'm making a big batch of chocolate overnight oats, these few items are game-changers:

  • Mason Jars: The 8oz wide-mouth ones are perfect for my kiddos appetites—not too big, not too small. Plus, they stack well in the fridge. If you are hungrier in the morning, try these 12 oz jars or something like these Weck Jars.
  • Bulk Oats: Buying old-fashioned oats in bulk (think Costco or Whole Foods bins) saves money and ensures you always have some on hand.
  • 4-Cup Liquid Measuring Cup: Helps speed up the measuring process when making a big batch for meal prep.
  • Dry Goods Scoop: Perfect for scooping out your oats and distributing them into the jars easily.

Flavor variations

If someone in your house isn’t all in on chocolate (can’t relate, but okay 😆), here are a few ways to mix things up:

  • Apple Cinnamon Oats: Great for little ones—use baby oatmeal for a smoother texture!
  • Carrot Cake Overnight Oats: Feels like dessert for breakfast but totally nutritious.
  • Vanilla Overnight Oatmeal: For the family member who likes to keep it classic, simple vanilla never fails.

Topping ideas

Toppings take Chocolate Overnight Oats to the next level! Here are a few of our favorites:

  • Nut Butter: Drizzle some melted peanut butter or almond butter for a chocolate-peanut butter combo (like in my chocolate peanut butter smoothie).
  • Fresh Fruit: Sliced strawberries, raspberries, and cherries pair great with chocolate.
  • Mini Chocolate Chips: Perfect for turning breakfast into an afternoon snack or even dessert.
  • Chopped Nuts: Add a little crunch—walnuts, almonds, or pecans work great.
  • Homemade Whipped Cream: Feeling fancy? A dollop of homemade whipped cream makes this simple breakfast feel extra indulgent.

Storage Tips

The overnight oats store well in the refrigerator for up to 5 days.  Perfect for prepping over the weekend, make a few different flavors at one time so you have a variety of options each morning (you won’t get bored, and your kids will love having a choice).

I like using wide mouth mason jars for storing overnight oats, but any container with a lid that seals will work.  Weck Jars are great, as are deli containers if you are on the go.
