How to Make 4-Ingredient Peanut Butter Banana Bars
Step 1: Preheat the Oven and Prepare the Pan
Preheat your oven to 350°F (175°C). Line a baking pan (8×8 inches works best) with parchment paper or lightly grease it with cooking spray. This ensures that the bars come out easily once they’re baked.
Step 2: Mash the Bananas
Peel the ripe bananas and mash them in a large mixing bowl. You can use a fork or a potato masher for this. The more mashed your bananas, the smoother the bars will be.
Step 3: Mix in Peanut Butter, Oats, and Honey
Add the peanut butter, rolled oats, and honey (or maple syrup) to the mashed bananas. Stir everything together until fully combined. The mixture should be thick but sticky.
Step 4: Bake the Bars
Transfer the mixture into the prepared baking pan and press it down evenly. Bake the bars in the preheated oven for 15-20 minutes, or until they’re lightly golden and firm to the touch.
Step 5: Cool and Slice
Once baked, remove the bars from the oven and allow them to cool in the pan for a few minutes. Once cooled, slice them into squares or bars, and they’re ready to enjoy!

Tips for Making the Best Peanut Butter Banana Bars
- Use Ripe Bananas: The riper your bananas, the sweeter the bars will be. Overripe bananas are ideal for this recipe since they’ll provide natural sweetness without needing added sugar.
- Choose Natural Peanut Butter: For the healthiest version, opt for natural peanut butter that only contains peanuts and maybe a little salt. Avoid peanut butter with added sugars or hydrogenated oils.
- Add-ins for Extra Flavor: If you like a little extra flavor or texture, consider adding chocolate chips, chopped nuts, or dried fruit to the mixture before baking.
- Store in an Airtight Container: These bars are perfect for meal prepping. Store them in an airtight container at room temperature for up to 4 days, or refrigerate them for up to a week.

- Top with a Drizzle: For an extra touch, drizzle dark chocolate or caramel sauce over the top of the bars before serving. This can elevate the flavor and make them feel like a dessert!
