Chocolate banana overnight oats are made with old fashioned rolled oats, bananas, dark cocoa powder and walnuts for deliciously satisfying breakfast that's filling.
This recipe was originally published in 2018. I've updated the ingredients and the photos for a better version of banana chocolate overnight oatmeal.

Even though they have been around for a while, I still love the simplicity of overnight oats. A few ingredients are mixed together and stored in the refrigerator while the oats soak and soften overnight. When it's time for breakfast you have a creamy and delicious serving of oatmeal.
They may taste a little bit like dessert, but don't let that fool you. Banana chocolate overnight oats are a very nutritious breakfast. They are loaded with protein, fiber, a variety of vitamins and minerals, and they are naturally sweet. You can eat them cold or heat them up for a hot serving of oatmeal.
If chocolate isn't your thing, you can always leave it out or give these apple cinnamon overnight oats a try.
Here is What You Will Need
- Old Fashioned Rolled Oats work the best. Instant oats will turn to mush.
- Chia Seeds thickens the oatmeal
- Almond Butter adds a touch of creaminess
- Water or your favorite milk. I find that the oatmeal is creamy and delicious with just water but you can use any type of milk if you prefer.
- Walnuts
- Ripe bananas that are soft and easy to mash sweeten the oatmeal naturally
- Dark unsweetened cocoa powder
- Maple syrup - optional
- A mixing bowl
- 8 ounce mason jars
Here's How to Make Chocolate Banana Overnight Oats
Add all of the ingredients into a bowl and mix them up.
For individual cups of oatmeal, divide the mixture into half and store it in 8 ounce mason jars or refrigerator storage containers.
Tips and Variations
- Mix overnight oats directly in mason jars by adding the ingredients to the mason jars instead of a bowl. This recipe makes two 8 ounce jars so you would have to split the ingredients in half and place them into each jar.
- Make a double batch to use throughout the week.
- Store the overnight oats in the refrigerator for 4 to 5 days.
- Change It up! Substitute the walnuts for sliced almonds, or chopped pecans. Add fresh raspberries, chopped cherries or dates to the oatmeal.

I'm not a huge oatmeal fan, but this totally looks like dessert. I bet I can trick myself into calling it pudding 😉
