I have to tell you, making the Peanut Butter and Banana Overnight Oats Recipe has completely changed my mornings. It’s one of those recipes that feels indulgent but is actually healthy. I love that I can prepare it the night before and wake up to a creamy, delicious breakfast.

Every bite is packed with flavor, and the texture is just perfect—soft oats with a hint of peanut butter and sweet banana. Honestly, it’s my go-to for busy mornings or when I want something comforting but nutritious. You can also enjoy a Copycat Nutter Butters Recipe as a sweet treat alongside this breakfast.

Ingredients

Here’s everything you need to make this overnight oats recipe come together perfectly:

1/2 cup old-fashioned rolled oats – These give the best texture; avoid instant oats as they can get mushy.
1 tablespoon chia seeds – They help thicken the oats and add a boost of fiber.
1 tablespoon peanut butter – I prefer natural peanut butter for rich flavor and less sugar.
1 cup milk (dairy or plant-based) – Almond, oat, or cow’s milk works; I like oat milk for creaminess.
1 ripe banana, mashed – Fresh bananas add sweetness naturally; overripe ones work best for flavor.
1 teaspoon honey or maple syrup – Optional, for extra sweetness if needed.
1/2 teaspoon vanilla extract – Enhances the overall flavor of the oats.
Pinch of salt – Balances sweetness and boosts flavor.

Note: several serving

Equipment You Need

Spoon or spatula – For mashing the banana and mixing ingredients.
Measuring cups and spoons – To keep the recipe balanced and consistent.

How to Make Peanut Butter and Banana Overnight Oats Recipe?

Step 1: Mash the Banana

Start by mashing your ripe banana in a bowl until smooth. I like a few small chunks left for texture, but you can mash it completely if you prefer creamier oats.

Step 2: Mix Wet Ingredients

Add peanut butter, milk, honey (if using), and vanilla extract to the mashed banana. Stir everything together until smooth and creamy, making sure the peanut butter is fully incorporated.

Step 3: Add Dry Ingredients

Stir in oats, chia seeds, and a pinch of salt. Make sure the oats are evenly coated with the wet mixture for consistent flavor in every bite.

Step 4: Refrigerate Overnight

Transfer the mixture to a mason jar or airtight container and refrigerate for at least 6 hours, or overnight. This allows the oats to soak and become creamy and soft.

Step 5: Serve

The next morning, give the oats a quick stir. If needed, add a splash of milk to loosen the mixture. Top with banana slices, a drizzle of peanut butter, or your favorite nuts for extra flavor and crunch.

Additional Tips for Making this Recipe Better

Here are a few things I’ve learned after making this recipe multiple times:

I always use a ripe banana; it naturally sweetens the oats and avoids extra sugar.
I mix in peanut butter well at the start; it helps prevent clumps and keeps the flavor consistent.
I like to let the oats sit for at least 8 hours; shorter times make them slightly chewier.
I occasionally add a pinch of cinnamon for extra warmth—it elevates the flavor completely.
I avoid using instant oats; they get too mushy and don’t hold the peanut butter flavor as well.

How to Serve Peanut Butter and Banana Overnight Oats?

Serving this recipe is half the fun! I love layering it in a mason jar with toppings for a pretty presentation. A few ideas:

Slice fresh bananas and sprinkle over the oats.
Add a handful of chopped nuts like almonds or walnuts for crunch.
Drizzle extra peanut butter or honey on top for a restaurant-style look.
Sprinkle cinnamon or cocoa powder to make it visually appealing and aromatic.
