How to Make Easy Banana Peanut Butter Oatmeal Bars

Step 1: Mash the Bananas

Start by peeling and mashing your ripe bananas in a large mixing bowl. You want them smooth and creamy, almost like a thick puree—this will give your Easy Banana Peanut Butter Oatmeal Bars that signature moist texture and natural sweetness.

Step 2: Mix in Peanut Butter, Sweetener, and Vanilla

Scoop in your creamy peanut butter, drizzle the honey (or maple syrup), and pour in the vanilla extract. Stir everything together until it’s wonderfully smooth and fully blended—no peanut butter lumps should remain!

Step 3: Stir in the Oats, Flaxseed, and Salt

Add the old-fashioned rolled oats, ground flaxseed if you’re using it, and a pinch of salt. Mix thoroughly so the oats are evenly coated in the banana-peanut mixture, ensuring every bar holds together beautifully.

Step 4: Fold in Nuts, Chocolate Chips, or Dried Fruit

If the mood strikes, gently fold in chopped nuts, mini chocolate chips, or dried fruit. This is when your bars get their extra pops of flavor and fun—make it your own by choosing your favorite add-ins!

Step 5: Prepare the Baking Dish

Line an 8×8-inch baking dish with parchment paper, letting it overhang the sides for easy removal later. This simple trick ensures you can lift the bars right out once they’re set, no sticking or messiness.

Step 6: Press and Shape the Bars

Spoon the oat mixture into your lined dish and press it down firmly using a spatula or your hands. Get it as compact and even as possible—this helps your Easy Banana Peanut Butter Oatmeal Bars hold together when sliced, keeping every bite chewy and cohesive.

Step 7: Chill Until Set

Pop the dish into the fridge and chill for at least 2 hours—or until everything is nice and firm. Patience is key here! Chilling creates that perfect bar texture you’re after.

Step 8: Slice and Serve

Lift the set mixture out of the pan using the overhanging parchment. Set it on a cutting board, then slice into bars or squares—however big or small you like. Enjoy every chewy, nutty, naturally sweet bite!

FAQs

Can I use crunchy peanut butter?

Absolutely! Crunchy peanut butter brings extra texture and little surprises of nutty goodness in every bite. Just be sure to mash your bananas super smooth so the overall mixture still comes together beautifully.

Are Easy Banana Peanut Butter Oatmeal Bars gluten-free?

They can be! Simply use certified gluten-free oats and double-check any add-ins like chocolate chips or dried fruit to make sure they’re gluten-free as well.

Can I make these vegan?

Yes! Use maple syrup instead of honey, and check that your chocolate chips (if using) are dairy-free. That’s all it takes to make plant-based Easy Banana Peanut Butter Oatmeal Bars you’ll love.

What can I use instead of peanut butter?

Try almond butter, cashew butter, or sunflower seed butter for a delicious alternative. Each nut butter brings its own unique character, so feel free to experiment to find your favorite version.

Do I have to chill them for the full 2 hours?

Chilling gives the bars time to set and makes slicing much easier, but if you’re in a rush, you can chill them for a minimum of 45–60 minutes. Just know they may be a bit softer, though still delicious!
