Ingredients and notes

This yummy treat is made with just 4 simple ingredients.

Peanut butter bars ingredients with text labels.

Graham Cracker crumbs

Graham crackers are sweet, mildly flavored crackers made from whole wheat flour, sugar, and honey.

When crushed into crumbs, they serve as a base for these peanut butter bars.

The crumbs add a slightly crunchy texture and a subtle sweetness to the bars.

You can grind up your graham crackers in the food processor or buy the pre-ground crumbs in a box. Since I’m all about easy recipes right now, I went for the box.

I find them in my regular grocery store, right in the baking aisle. Or you can order them online. Here’s a link: graham cracker crumbs.

Powdered sugar

Powdered sugar is used in the peanut butter filling to add sweetness and make it creamy.

Chocolate chips

Chocolate chips are used in the topping for the top layer providing a rich, melty, and chocolaty element to the dessert.

Peanut butter

Serves as the main ingredient in the filling, giving a creamy and slightly savory taste that pairs exceptionally well with chocolate.

Peanut butter also provides healthy fats, protein, and other nutrients.

I use regular creamy peanut butter.

You could probably use the crunchy kind, too, if you like.

I haven’t tried using natural peanut butter, but I think it would probably work if you’re looking for a healthier option.

Key equipment

How to make peanut butter bars

Step 1: Make the base layer

Start by tossing the graham cracker crumbs, peanut butter, and powdered sugar in a large mixing bowl.

Stir everything together on low speed to get it combined.

At first, the mixture may look dry. But if you keep going, it will come together!

Once everything’s fully incorporated it will have a texture almost like a firm cookie dough.

Next, just tip the mixture into a parchment-lined 9×13 inch pan.

You can do it in an 8×8 or 9×9 pan, too- your bars will just come out thicker.

Step 2: Make the topping

The topping is made by melting chocolate with peanut butter.

You can do this in a double boiler or the microwave.

I chose to do it in the microwave. It only took about a minute. Just hit it with quick, 20-second bursts, stirring after each, until the mixture is smooth and luscious.

Step 3: Chill

Allow the bars to chill until the top layer is set.

In my fridge, this took about 1 hour. Once they’re set, they can be cut into bars and enjoyed!

Expert tips

Use high-quality ingredients

Using high-quality ingredients such as good peanut butter, high-quality chocolate chips, and fresh graham crackers can significantly improve the taste and overall quality of your peanut butter bars.

Optimize peanut butter consistency

Depending on the recipe, you may need to adjust the consistency of the peanut butter.

If it’s too thick, you can heat it slightly or mix in a small amount of oil to thin it out.

If it’s too runny, you can add a bit more powdered sugar or graham cracker crumbs to thicken it.

Mix thoroughly

Ensure all the ingredients are thoroughly combined when making the peanut butter filling. This will yield a smooth and consistent texture throughout the bars.

Take your time to mix well and work out any lumps.

Chill properly

After assembling the peanut butter bars, it’s important to refrigerate them until the topping is set.

Recipe FAQ’S’s

These are made with simple ingredients, including graham cracker crumbs, powdered sugar, peanut butter, and chocolate chips.

You don’t need any butter.

Some recipes incorporate additional mix-ins to add texture or flavor variations. These can include chocolate chips, chopped nuts (such as peanuts), shredded coconut, or even oats.

How do you make peanut butter bars gluten-free?

To make a gluten-free version of this recipe, look for gluten-free graham cracker crumbs.

Can peanut butter bars be made dairy-free?

These can also be made dairy-free if you use dairy-free chocolate chips.

How to serve

  1. Enjoy the peanut butter bars as they are, straight from the pan or platter. Serve them at room temperature or slightly chilled.
  2. Crumble peanut butter bars over a scoop of vanilla or chocolate ice cream. The combination of the creamy ice cream, rich peanut butter flavors, and crunchy texture of the bars is so good!
  3. Slice the peanut butter bars in half horizontally and spread a layer of additional peanut butter or chocolate hazelnut spread in the center. Sandwich them back together and enjoy a truly indulgent treat!
  4. Warm the peanut butter bars slightly in the microwave or oven and serve them with a scoop of ice cream or a drizzle of warm caramel or chocolate sauce. The warm and melty bars and cold ice cream create a delightful contrast.
  5. Cut the peanut butter bars into small squares or rectangles, wrap them in decorative packaging, place them in individual treat bags, and give them as gifts or party favors.

How to store and keep

As long as it’s not too hot in your house, these peanut butter bars can be wrapped and kept on the counter for several days.

They should be ok to sit out without melting.

Once they’ve chilled in the fridge and the chocolate is set, they should stay that way, although they will be slightly softer at room temperature.

They should last for around two weeks in the fridge when stored in an airtight container.
