- Stir in half the peanut butter and swirl the rest on top before refrigerating for gorgeous ribbons throughout instead of one uniform color
- Add a pinch of cinnamon or vanilla extract to enhance the peanut butter banana flavor combination
- Prefer thicker oats? Use a 1:1 ratio of oats to milk instead of the standard 1:2 for a spoonable texture that holds its shape

Peanut Butter Banana Overnight Oats
Ingredients
Method
- In a medium bowl or mason jar, mash the banana with a fork until mostly smooth with a few small chunks remaining.
- Add the rolled oats, milk, chia seeds, vanilla extract, cinnamon, and salt to the mashed banana. Stir until everything is well combined.
- Add 1 tablespoon of peanut butter to the mixture and stir it in completely. Take the remaining tablespoon and swirl it on top for a marbled effect.
- Cover the bowl or jar tightly with a lid or plastic wrap. Refrigerate for at least 6 hours or overnight, allowing the oats to absorb the liquid and soften.
- In the morning, give the oats a good stir. If they’re too thick, add a splash of milk to reach your desired consistency.
- Top with fresh banana slices, extra peanut butter drizzle, granola, or your favorite toppings before serving. Enjoy cold or microwave for 30-45 seconds if you prefer them warm.

Frequently Asked Questions
Can I use a different nut butter?
Absolutely! Almond butter, cashew butter, or sunflower seed butter work beautifully. Just maintain the same 2-tablespoon measurement for proper consistency.
Do these need to sit overnight or can I eat them sooner?
While they’re best after 6-8 hours when the oats fully soften, you can eat them after 2 hours in a pinch. The texture just won’t be as creamy.
What’s the best milk for overnight oats?
Any milk works — dairy, almond, oat, or soy. Creamier milks like oat or whole dairy milk create a richer texture, while almond milk keeps them lighter.
Why are my overnight oats watery?
You likely added too much liquid. Stick to the 1:2 ratio (oats to milk) and remember the banana adds moisture too. If they’re too thin, stir in a tablespoon of chia seeds to thicken.
Storage & Serving
Store these oats in an airtight container or mason jar in the refrigerator for up to 4 days. Top with sliced banana, a drizzle of honey, granola, or dark chocolate chips right before eating. They’re delicious cold straight from the fridge or warmed in the microwave for 30-45 seconds if you prefer them cozy. For grab-and-go mornings, portion them into individual jars so you can just grab and eat.
