No Bake Chocolate Peanut Butter Bars

These peanut butter bars are so easy to make and are ready to eat in 30 minutes or less! Chances are you have most of these ingredients in your pantry, if not all of them.

Why this recipe works

Recipes that don’t require baking are easy and great any time of year. While they are a year-round treat, these peanut butter bars are especially wonderful in the summer, when you don’t want to crank up your oven. And with them being so quick to make, they’re perfect for unexpected company or that last-minute teen request.

Ingredient Info and Substitute Suggestions

CHOCOLATE – I prefer to use baking chocolate for these bars as it’s easier to melt in my opinion, however, you can also use chocolate chips. Semi-sweet, dark chocolate, or milk chocolate are all great options.

PEANUT BUTTER – I used regular creamy peanut butter for this recipe. I have not tested this recipe with natural peanut butter. In natural peanut butter, the oil separates from the butter itself therefore I am uncertain if the bars will harden completely. Some of my readers have suggested adding extra animal cracker/graham cracker crumbs to help it solidify better if you do take this route.

Spread over the top of the peanut butter layer.

Frequently Asked Questions

What if I don’t have a food processor?

You can use a hand mixer or even a blender if you don’t have a food processor. We like the food processor because it makes for the smoothest mixture.

Do these taste like Reese’s peanut butter cups?

This recipe uses semi sweet chocolate for the topping. If you want it a bit sweeter, and closer to the flavor of a Reese’s Peanut Butter Cup, simply substitute milk chocolate for the semi sweet. I prefer to use baking chocolate, but you can certainly use chocolate chips instead.

Can I freeze them?

Yes, absolutely. I would suggest flash freezing the bars first, removing them from the freezer once they are mostly frozen, then transferring them to a large ziptop bag or air-tight container. Freeze for up to 3 months.
