I’m wild about these Peanut Butter Banana Overnight Oats! They're my go-to when mornings fly by. Toss everything together the night before and wake up to oats that are sweet, rich, and filling. Since they’re loaded with protein, fiber, and healthy fats, I don’t end up hungry again right away.

This was a classic dorm hack when I was broke and frantic in college. Now it’s something my whole crew looks forward to every week.

Creamy Peanut Butter Banana Overnight Oats – Ingredients

  • Pinch of salt: just a little goes a long way to make everything pop—sea salt works great
  • Maple syrup or agave nectar: if you love things sweeter, pour in a bit of pure syrup or nectar
  • Cinnamon: optional, but it gives things a nice warm flavor—just make sure it's fresh for max aroma
  • Vanilla extract: a splash makes things taste cozy—pure vanilla is best if you have it
  • Chia seeds: you can toss them in for extra fiber or if you like a pudding vibe—use whole seeds for a good texture
  • Peanut butter: go for natural peanut butter, just peanuts and salt—it pumps up the protein and creamy taste
  • Plant-based milk: whatever type you’ve got—soy, almond, oat—unsweetened is a good call for less sugar
  • Rolled oats: use whole ones for chewy texture and solid energy that lasts
  • Ripe banana: brown spots are your friend—they bring the most flavor and make everything sweet and smooth

Simple Step-by-Step Directions

Finish and add toppings:
After the fridge time, stir your oats well. You can keep them cold or microwave for about 30 seconds if you want them warm. Stack on any extras—more banana, peanut butter, or chopped nuts for fun.
Chill overnight:
Pack the oat mixture into a lidded container, close it tight, and let it sit in the fridge for at least four hours (overnight is best). That way, the oats get soft and all the flavors come together.
Check sweetness:
Give everything a taste. If it’s not sweet enough, mix in some maple syrup or agave nectar until it’s just right. Be sure everything’s mixed up.
Combine your base:
Start by adding rolled oats, non-dairy milk, peanut butter, chia seeds, vanilla, cinnamon, and a bit of salt into the bowl with your mashed banana. Mix it up well so the peanut butter melts in smooth.
Smash the banana:
Take a ripe banana, peel it, and mash it with a fork until it’s totally mushy. This gives your oats creamy sweetness all the way through.

Peanut butter’s always the hero in my pantry. Pop the lid on a new jar for this and the whole place just smells welcoming! My kiddo likes to mash up the bananas... and sneak a few tastes for herself.

How to Store

Stick your oats in the fridge and cover them up tight. They’ll stay tasty for three days easy. If they get thick, a little extra milk brings them right back to creamy.

Switch It Up

No nuts? Use tahini or sunflower seed butter—works a treat! Want it extra smooth? Try quick oats. Need more protein? A scoop of your favorite plant-based protein powder fits right in.
