Healthy No Bake Peanut Butter Bars Recipe

If you know me, you know I will always say yes to peanut butter and chocolate. It’s one of my favorite combinations, and these no bake bars keep it simple!

The base is made with peanut butter, oat flour, and maple syrup, so it comes together quickly and firms up nicely once chilled. Then you add a smooth chocolate layer on top, which gives each bite that sweet-salty balance that makes these so good.

I also love that these no bake peanut butter chocolate bars are easy to keep in the fridge or freezer. They’re great for meal prep, easy to portion out, and nice to have on hand when you want a homemade treat that is ready to go!

Why You’ll Love These Healthy No Bake Peanut Butter Bars

Just four ingredients. Peanut butter, oat flour, maple syrup, and chocolate chips, that’s genuinely all you need! It doesn’t get much better than that.
No oven required. These are fully no bake, which means you can make them any time of year without heating up your kitchen.
They taste like a Reese’s cup. That salty peanut butter base + chocolate topping combo is absolutely unreal.
Perfect for meal prep. Make a batch on Sunday and snack on them all week straight from the fridge or freezer.
Easy to customize. Add flaky sea salt on top, swap in almond butter, or drizzle with white chocolate, these bars are a total blank canvas!

Ingredients Needed

Making a batch of these no-bake chocolate peanut butter bars are simple and requires only four ingredients.

Peanut butter: You’ll need creamy peanut butter for the base and more for the topping if you’re mixing it with the melted chocolate. I like salted peanut butter for the sweet-salty flavor, but creamy unsalted works too!
Oat flour: Oat flour gives the bars structure and a soft, sturdy texture. Store-bought is usually a little finer, but homemade works too if you blend rolled oats until very smooth. Using oat flour make these peanut butter bars completely gluten-free!
Maple syrup: This sweetens the bars and help bring the base together. Honey or agave can work too.
Chocolate chips: For the topping! Mini chocolate chips melt easily, but regular chocolate chips work just as well! You can use semi-sweet or dark chocolate chips.

Tip: For a yummy twist, you can add 1/2 cup of shredded coconut or chopped nuts as a topping. It can add an additional crunch and texture.

How to Make Easy Healthy Peanut Butter Bars

Step 1: Make the peanut butter base. In a medium bowl, mix together peanut butter, maple syrup, and oat flour until a thick dough forms. Press the mixture firmly and evenly into a parchment-lined 8×8 baking dish.

Step 2: Make the chocolate topping. Add chocolate chips and peanut butter to a microwave-safe bowl. Microwave in 30-second increments, stirring between each, until completely smooth.

Step 3: Assemble and freeze. Pour the melted chocolate mixture over the peanut butter base and spread evenly. Transfer to the freezer for 1 hour, or until fully set and firm enough to slice cleanly.

Step 4: Slice and serve. Lift the bars out using the parchment paper, cut into 12 bars, and enjoy! Store in the fridge or freezer

Erin’s Expert Recipe Tips

Use salted peanut butter. It’s the secret to that addictive sweet & salty balance. If you only have unsalted, add a pinch of salt to the base.
Line your dish with parchment paper. It makes cleanup easy and helps you pull out perfectly clean bars for slicing!
Don’t rush the freeze. A full hour in the freezer is key so the chocolate sets properly and the bars hold their shape when sliced.
Use a warm knife for cleaner slices. Run your knife under hot water, dry it, and then slice. The chocolate won’t crack or shatter.
Storing: Keep bars in an airtight container in the fridge for up to 1 week, or freeze for up to 3 months. To freeze without sticking, lay bars in a single layer first, then transfer to a freezer-safe bag or container.

Frequently Asked Questions

Below are some common no bake peanut butter bar recipe questions. Don’t see the answer you’re looking for? Leave a comment at the bottom of this post!

Why are my peanut butter bars crumbly?

Usually, that means the mixture is a little too dry, or the peanut butter was too thick. Make sure everything is fully mixed, and the base is soft enough to press firmly into the pan. Using a creamier peanut butter helps a lot.

What’s the best peanut butter for no-bake peanut butter bars?

For these no-bake peanut butter bars, I recommend using a creamy, salted peanut butter. It can be natural, but it might make the base mixture more dry. If you find the base mixture is too dry, you’ll want to add just a dash of water to make it smoother.

Can I double this recipe?

Yes. Double the ingredients and use a 9×13 pan if you want a bigger batch for sharing or meal prep.

Notes

Use salted peanut butter for the best flavor. The sweet-salty balance is what makes these bars so good! If you only have unsalted, just add a pinch of salt to the base mixture.
Line your dish with parchment paper. It makes cleanup a breeze AND helps you get cleaner slices later. Totally worth the extra 30 seconds!
Don’t skip the freezer step. The bars need to go in the freezer for a full hour before slicing. This ensures the chocolate layer sets properly so everything cuts cleanly and holds together.
