Peanut Butter & Banana Overnight Oatmeal

Peanut Butter and Banana Overnight Oatmeal: no-bake, vegan, gluten-free, and tastes amazing!!

10 MIN


4-6 Servings

Overnight oatmeal is the perfect breakfast!  You just add rolled oats, your milk of choice, and sweetener in a jar, shake it up, and put it in the fridge overnight. There’s no baking!  I love coming home from a hot morning run and having cold oats for breakfast!  For this recipe, I added bananas, peanut butter, cinnamon, and walnuts to make it taste like banana bread…yum!

Assembly is so easy!

Add your rolled oats to a large (quart-sized) jar.  Then add the almond milk, vanilla extract, maple syrup, peanut butter, cinnamon, nutmeg, and salt into the jar.

Mash 2 ripe bananas in a separate bowl and add to the jar.

Stir and seal with the lid.  I like to give mine a good shake to make sure everything is well-mixed.

Place your jar in the refrigerator overnight.  That’s it!  Your overnight oatmeal will be ready in the morning!

You can enjoy your oats cold and straight from the jar, or you can add them to a bowl and warm them up.  Add your favorite toppings and you’re good to go!


2 cups old-fashioned rolled oats*
2 cups unsweetened almond milk (or light coconut milk)
1 teaspoon pure vanilla extract
3 tablespoons pure maple syrup or honey
3 tablespoons unsweetened peanut butter (or nut butter of your choice)
2 large ripe bananas, mashed
3/4 teaspoon ground cinnamon
1/4 teaspoon ground nutmeg
¼ teaspoons sea salt

Optional Topping Suggestions:
Peanut butter
Sliced banana
Ground cinnamon
Raw walnuts, chopped
Dairy-free milk of choice


Pour the rolled oats into a large (quart-sized) jar.
Add the almond milk, vanilla extract, maple syrup, ground cinnamon, ground nutmeg, peanut butter, and salt into the jar with the rolled oats.
Mash the ripe bananas in a bowl and add them to the jar. Stir everything together until well combined. Seal the jar and place it in the refrigerator.  Allow the oats to sit overnight.
When ready to serve, stir the oatmeal well. Serve with your preferred toppings: maple syrup, peanut butter, raisins, chopped walnuts, granola, cinnamon, bananas, and/or a splash of your favorite milk (such as almond milk or coconut milk)

Do not use quick or instant oats.

    Yummy! I love overnight oats. My favorite way to make them is with ground coffee, cacao nibs, and a few chocolate chips – so good it could almost be dessert!

    Most people don’t think of oatmeal as refreshing but I find cold overnight oats to be just that! I’ve experimented with tons of flavor combinations but I always come back to Chocolate PB2, instant coffee granules and a little cinnamon. Pumpkin pie spice and 100% pure pumpkin is a favorite in the fall. Mmmmmm……. :)
