Take 5 minutes to prep these Chocolate Pistachio Overnight Oats and breakfast will be ready and waiting for you when you wake up. A sweet and salty breakfast or snack that you will love!

Chocolate for breakfast is a delightful treat, and when paired with oats and crunchy pistachios it becomes an easy, satisfying start to the day.
These Chocolate Pistachio Overnight Oats are quick to assemble, naturally sweet with a hint of salt from the nuts, and perfect for grabbing on busy mornings or enjoying as a cozy snack.
I love pistachios — they add a unique flavor and texture. If you enjoy pistachio-forward breakfasts, you might also like my Honey Pistachio Avocado Toast, but for a sweeter option, this chocolatey oatmeal wins every time.
Why You Will Love These Chocolate Pistachio Overnight Oats:
- Make ahead. Prep these the night before and breakfast is ready when you are — one of the best conveniences of overnight oats.
- Simple ingredients. Basic pantry staples are all you need. Pistachios are optional but make the dish special. Chia or flax seeds can be added if you like.
- Chocolate. Cocoa powder gives a rich chocolate flavor that works wonderfully for breakfast.
- Adaptable for dietary needs. Use gluten-free oats if needed and any milk you prefer — dairy or plant-based — even chocolate milk if you want to boost the chocolate flavor.
Recipe Ingredients:
You don’t need much: rolled oats, milk, cocoa powder, vanilla, a sweetener, and pistachios. I often keep these items on hand, which makes this recipe quick to throw together.
Optional additions like flax or chia seeds add fiber and texture, but the oats are delicious without them as well.

Storing Your Pistachio Overnight Oatmeal:
Store overnight oats in the refrigerator for up to 5 days. If you plan to add banana, add it just before serving to avoid browning. Berries and other fresh fruit work well and can be mixed in either before chilling or just before eating.
Other Overnight Oats Flavors to Try:
- Triple Chocolate
- Coconut Cream Pie
- Zucchini Bread
- Banana Bread
- Blueberry Muffin
- Peanut Butter Chocolate
- Vanilla Cold Brew
- Peach Pie
- Apple Pie
Recipe Notes and Tips:
- Sweeten to taste at serving. Personal preference varies, so add maple syrup or another sweetener when you’re ready to eat to control the sweetness.
- Enjoy hot or cold. Overnight oats are delicious chilled, but many people prefer them warmed for about a minute in the microwave.
- Toast the pistachios for extra flavor. Lightly toast shelled pistachios in a dry skillet for about 5 minutes, or toss them with a little maple syrup before toasting for a caramelized finish.
