Ingredients
Full ingredients and substitutions are in the recipe box below.
- Rolled oats: old-fashioned oats give the best creamy texture. You can use quick oats for softer peanut butter banana oats, or gluten-free oats if needed.
- Banana: ripe banana adds natural sweetness and creaminess. Swap with mashed applesauce or pumpkin puree for a different flavor.
- Greek yogurt: makes the oats rich and protein-packed. Substitute low-fat Greek yogurt or Skyr for even more protein, or use a dairy-free yogurt if preferred.
- Milk: any milk works here. Use dairy milk, almond, soy, or oat milk depending on what you like or have on hand.
- Peanut butter: use 100% natural peanut butter, well stirred, for the best texture. Look for jars made with just peanuts (and maybe salt), like Trader Joe’s, 365 by Whole Foods, Crazy Richard’s, Teddie, Smucker’s Natural, Santa Cruz Organic, Once Again, Spread The Love, or Kirkland Signature. You can recognize it by the oil layer on top and a softer, drizzly texture after stirring. Avoid ones with additives or sugar. Swap with almond butter, cashew butter, or sunflower seed butter.
- Honey or maple syrup: adds a touch of sweetness. You can skip it if your banana is very ripe, or use mashed dates.
- Cinnamon: brings warmth and depth. Try pumpkin spice or a pinch of nutmeg for a twist in this no cook oatmeal recipe.
How to Make Peanut Butter Banana Overnight Oats
Step 1. Mash banana and mix with peanut butter
Peel the banana and add it to a medium bowl.
Mash it well with a fork until it turns into a thick, creamy paste. A few small lumps are fine.
Add the peanut butter and stir until smooth and fully combined.
Step 2. Add the wet ingredients
Add the Greek yogurt, milk, honey or maple syrup, and cinnamon.
Whisk well until everything looks smooth and creamy. The mixture should be thick but easy to mix, with no peanut butter clumps.
Step 3. Add oats and chill
Stir in the rolled oats until they are fully coated. Check the sides and bottom so there are no dry spots.
Transfer the mixture into single-portion jars, or keep it in the bowl. Cover and place in the refrigerator for at least 6 hours, or overnight.
As the oats rest, they soak up the liquid and turn soft and creamy. This is what gives you that classic overnight oats texture.
Step 4. Stir and serve
In the morning, give the oats a good stir.
If they are too thick, add a small splash of milk and mix again.
Top with banana slices, chopped peanuts, or cacao nibs, and enjoy cold or warm briefly in the microwave.
Tips
- Use 100% natural peanut butter: choose one made with just peanuts (and maybe salt). It’s less processed, blends better, and keeps the flavor clean and balanced.
- Mash the banana well: the smoother it is, the creamier your oats will be. A few small lumps are okay, but avoid big chunks.
- Adjust the texture in the morning: if the oats feel too thick, add a small splash of milk and stir until creamy again.
- Taste before chilling: give the mixture a quick taste and adjust sweetness if needed, especially if your banana isn’t very ripe.
- Let it rest long enough: at least 6 hours helps the oats fully soften and absorb the liquid for the best texture.
- Stir well before serving: the mixture can settle overnight, so a quick stir makes everything creamy again.
- If you are cooking for mixed diets: use dairy-free yogurt and plant milk for a fully plant-based version, or regular dairy for a higher-protein option.
- Make it your own: add chia seeds, flaxseeds, or a scoop of protein powder if you like a thicker, more filling breakfast.
