Salty, no bake chocolate 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 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!

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 1 cup of 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: You’ll need 1 cup of oat flour to give 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.
• Maple syrup: You’ll need 1/4 cup maple syrup to sweeten the bars and help bring the base together. Honey or agave can work too.
• Chocolate chips: You’ll need 1/2 cup of 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.

Kitchen tools required

• Medium mixing bowl
• 8×8 baking dish
• Small microwave-safe bowl
• Spoon or spatula
• Parchment paper, optional but helpful

How to make healthy peanut butter bars

Add the peanut butter, maple syrup, and oat flour to a medium bowl. Stir until a thick dough forms, and everything looks fully combined. The mixture should be soft enough to press into the dish, but not sticky or runny.

Press the peanut butter mixture into an 8×8 baking dish in an even layer. If you want easy cleanup and cleaner slices later, line the dish with parchment paper first!

In a small microwave-safe bowl, melt the chocolate chips in 30-second increments, stirring well between each one. If you’re adding extra peanut butter to the topping, stir that in once the chocolate is smooth.

Pour the melted chocolate over the top of the peanut butter layer and spread it out evenly. Place the dish in the freezer for about 1 hour, or until the bars are firm enough to slice cleanly.

Remove from the dish, cut into bars, and enjoy.

Below are some common 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. Similar peanut butter bar recipes and troubleshooting posts flag dry dough and not enough binding fat as common reasons bars fall apart. 

HOW DO I KEEP THE CHOCOLATE TOPPING FROM CRACKING?

Let the bars sit for a few minutes before slicing if they’re very firm from the freezer. Using a warm knife also helps the chocolate cut more cleanly instead of snapping.

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.

CAN I TURN THESE INTO PEANUT BUTTER BALLS?

Yes, you can. Roll the base mixture into balls, chill until firm, then dip or drizzle with melted chocolate.

CAN I FREEZE PEANUT BUTTER BARS?

Yes, these freeze well. Freezing in a single layer first, then transferring to a container or bag, is a common method for keeping bars from sticking together. Comparable no-bake bar recipes suggest freezing after the bars are fully set and then storing them wrapped or layered for easier grab-and-go portions.

Store these healthy peanut butter bars in an airtight container in the refrigerator for up to 1 week. Chilled storage is commonly recommended for no-bake peanut butter bars because it helps them keep their shape and texture. 

You can also freeze them for longer storage. To make that easier, freeze the bars in a single layer first, then transfer them to a freezer-safe container or bag so they do not stick together. That method is widely recommended in similar bar recipes.
