Creamy Peanut Butter Banana Overnight Oats

If I had to pick one overnight oats recipe to eat forever, it would be this peanut butter banana version. I’ve made these countless times, and so have many readers. They come together in under five minutes and are smooth, creamy, and satisfying. I love finishing them with a generous dollop of peanut butter and extra banana slices. Lately I also add a scoop of protein powder for an extra boost.

This peanut butter banana overnight oats recipe is one of the most popular breakfasts on Fit Foodie Finds for good reason. It’s naturally sweetened with banana and a touch of honey, thickened with Greek yogurt and peanut butter, and holds up well for meal prep. Even picky eaters tend to love it — my toddler is obsessed with these oats!

What’s in Peanut Butter Banana Overnight Oats?

This version relies on simple pantry staples to create a creamy, balanced breakfast. The mashed banana and honey add sweetness, while Greek yogurt and peanut butter give the mixture a rich, silky texture and boost the protein. Chia seeds add structure and omega-3s, and cinnamon and vanilla round out the flavor.

• Rolled oats (quick oats can be used, but rolled oats give a better texture)
• Creamy peanut butter
• Banana (mashed)
• Unsweetened almond milk (or any milk you prefer)
• Greek yogurt (plain)
• Honey (for sweetness)
• Chia seeds
• Cinnamon
• Vanilla extract

Variations for PB Banana Overnight Oats

• Add protein: Stir in one or two tablespoons of your favorite protein powder or collagen for extra protein.
• Swap sweeteners: Use maple syrup, agave, or a little brown sugar instead of honey to change the flavor profile.
• Change the nut butter: If peanut butter isn’t your thing, sub in almond butter, cashew butter, or another nut/seed butter for a different taste.

Topping Ideas

Toppings take these oats from good to great. My favorites are extra banana slices, a spoonful of creamy peanut butter, and a handful of chopped peanuts for crunch. Other tasty options include:

• Fresh berries
• Mini chocolate chips
• Fresh lemon zest for brightness
• A splash of extra almond milk to loosen the texture
• Dried cranberries or other dried fruit

How long do PB Banana Overnight Oats last in the fridge?

Stored in an airtight container, these overnight oats will keep well in the refrigerator for about 3–4 days. For the best texture and flavor, add fresh toppings just before serving.
