Ingredients
For the Overnight Oats
- ½ cup old-fashioned rolled oats
- 1 tablespoon chia seeds
- ½ ripe banana, mashed
- 1 tablespoon creamy peanut butter
- ½ cup milk of your choice
- ¼ teaspoon vanilla extract
- ½ teaspoon honey or maple syrup, optional
- ¼ teaspoon ground cinnamon
- Pinch of salt
For the Topping
- ½ banana, sliced
- 1 tablespoon roasted peanuts, chopped
- 1 teaspoon chia seeds

How to Make Banana Peanut Butter Chia Overnight Oats
Step 1: Mash the Banana
Start with a ripe banana. The riper the banana, the sweeter and more flavorful your oats will be.
Place half of the banana in a bowl or directly into your jar and mash it with a fork until mostly smooth. A few small banana pieces are totally fine.
The mashed banana blends into the oat mixture and adds natural sweetness without needing a lot of extra sugar.
Step 2: Add the Oats and Chia Seeds
Add the rolled oats and chia seeds to the mashed banana.
Stir them together so the chia seeds are evenly distributed. This is important because chia seeds absorb liquid as they sit. Mixing them well helps prevent large clumps from forming.
For the best texture, use old-fashioned rolled oats rather than quick oats or steel-cut oats.
Step 3: Add Peanut Butter
Add one tablespoon of creamy peanut butter.
Peanut butter gives the overnight oats a rich, nutty flavor that pairs really well with banana. If your peanut butter is thick, you can warm it for a few seconds or mix it with a splash of milk before adding it.
For an extra peanut butter flavor, you can use another tablespoon in the topping.
Step 4: Add Milk and Flavorings
Pour in the milk, then add vanilla extract, cinnamon, and a small pinch of salt.
If your banana isn’t very ripe or you simply like sweeter overnight oats, add a little honey or maple syrup.
Stir everything together until well combined.
The mixture may look fairly loose at this point, but don’t worry. The oats and chia seeds will absorb the milk while they sit in the refrigerator.
Step 5: Refrigerate Overnight
Cover the bowl or jar and place it in the refrigerator for at least 4 hours, although overnight is best.
During this time, the oats soften and the chia seeds absorb the liquid. The result is a thick, creamy mixture with a pudding-like texture.
If you prefer thinner overnight oats, simply add another splash of milk in the morning and stir.
Step 6: Add the Toppings
When you’re ready to eat, give the oats a good stir.
Slice the remaining banana and arrange it on top. Add chopped roasted peanuts and another sprinkle of chia seeds.
Finish with a spoonful of peanut butter and, if desired, a light drizzle of honey or maple syrup.
Serve cold straight from the refrigerator.
Tips for the Best Overnight Oats
Use a ripe banana: A ripe banana gives the oats much more flavor and natural sweetness.
Don’t skip the chia seeds: Chia seeds help create the thick, creamy texture that makes overnight oats so good.
Adjust the consistency: If your oats become too thick, stir in 1–2 tablespoons of milk until they reach the texture you like.
Use natural peanut butter: Creamy peanut butter works best, but crunchy peanut butter is also delicious if you want extra texture.
Let them sit long enough: Four hours will work, but leaving the oats overnight gives the ingredients more time to soften and blend together.
Add toppings right before eating: Fresh banana and peanuts taste best when added just before serving.
Easy Variations
Chocolate Banana Peanut Butter Oats
Turn this into a chocolate breakfast by mixing in 1 tablespoon of unsweetened cocoa powder. You can also add a few dark chocolate chips on top.
Strawberry Banana Oats
Add sliced strawberries along with the banana. The fresh berries give the oats a bright, fruity flavor.
Cinnamon Roll Version
Add extra cinnamon, a splash of vanilla, and a little maple syrup. This gives the oats a warm cinnamon-roll-inspired taste.
Protein Overnight Oats
For a higher-protein breakfast, mix in your favorite protein powder. You may need to add a little extra milk to keep the oats creamy.
Apple Peanut Butter Oats
Replace some of the banana topping with finely chopped apple. Add a little extra cinnamon for a simple apple-and-peanut-butter combination.
How to Store
Keep the prepared overnight oats in a clean, airtight container or covered jar in the refrigerator.
For the best taste and texture, enjoy them within 3–4 days. If you’re meal prepping, you can prepare several individual jars at the same time.
Keep fresh banana toppings separate if possible. Add them right before serving to help prevent them from becoming overly soft or brown.
Frequently Asked Questions
Can I make these overnight oats without chia seeds?
Yes. Chia seeds help thicken the mixture, but you can leave them out. If you do, start with slightly less milk and adjust the consistency in the morning.
Can I use quick oats?
You can, but the texture will be softer and less chewy. Rolled oats are usually the best choice for overnight oats.
Can I eat them immediately?
You can, but they won’t have the same creamy texture. Letting them sit for at least 4 hours gives the oats and chia seeds enough time to absorb the liquid.
Can I use almond butter instead of peanut butter?
Absolutely. Almond butter, cashew butter, or sunflower seed butter can all work well.
Are overnight oats served hot or cold?
They’re usually served cold straight from the refrigerator. If you prefer a warm breakfast, you can gently heat them before eating and add your toppings afterward.
