No Bake Pretzel Peanut Butter Bars

I’m not sure whether to hug or curse the person who invented no-bake peanut butter bars. This homemade version of a peanut butter cup is so ridiculously simple that you might never buy a packaged peanut butter cup at the store again. Especially since you can stash these in your freezer and just take one out to nibble on every now and then. IT’S JUST TOO EASY.

No-bake peanut butter bars have been around for eons. Well, decades at least. There are a million versions of this recipe out there, but mine have a slightly more even ratio between the chocolate and peanut butter portions, and I like to nestle a little mini-pretzel in the top for a little added crunch.

Oh, and most no-bake peanut butter bar recipes usually specify not to use natural-style peanut butter, but that’s what I use with mine and it works just fine! :)

What Kind of Nut Butter Can I Use?

I used a natural-style peanut butter made with just peanuts and salt for these peanut butter bars. If you’re allergic to peanuts you can use a different type of nut butter, like almond or cashew (although those will be quite a bit more expensive).

Just make sure you choose a nut butter that is quite firm when refrigerated and soft when room temperature. As long as it firms up when refrigerated, it will work for these bars. Oh, and make sure it has at least a little salt and is very well stirred before adding to the recipe. Too much oil and the bars won’t set.

Choose Your Chocolate

This recipe is also fairly flexible when it comes to the type of chocolate used. I used plain old semi-sweet chocolate chips, but you could have a little fun and use dark chocolate, or a different flavored chocolate chip if you’d like.

How to Store Peanut Butter Bars

You’ll want to keep these peanut butter bars refrigerated so they don’t melt. I suggest keeping them in an air-tight container in the refrigerator no longer than a week, or you can freeze them for longer storage (freezer bag, up to three months or so). To thaw, just let them sit out at room temperature for about 10 minutes.

Total Cost: $3.94 recipe / $0.16 per square
Author: Beth – Budget Bytes
Prep Time: 15 mins
Refrigerate Time: 2 hrs
Total Time: 2 hrs 15 mins
Servings: 25 1 square

Ingredients

  • 1 cup graham cracker crumbs (about 8 sheets) ($0.38)
  • 1/2 cup butter ($0.82)
  • 1 cup peanut butter (+ 2 Tbsp) ($1.38)
  • 1 cup powdered sugar ($0.07)
  • 1.5 cups chocolate chips ($1.19)
  • 25 mini pretzels ($0.10)

Instructions

  • If your graham crackers aren't already in crumb form, use a food processor to blitz them into a fine crumb.
  • Place the butter and 1 cup of peanut butter in a bowl. Microwave and stir in 30-second intervals, just until they're warm enough to melt together. Stir until evenly combined. (Reserve the last 2 Tbsp peanut butter for later.)
  • Add the powdered sugar and graham cracker crumbs to the melted peanut butter mixture and stir until evenly combined.
  • Line an 8×8-inch baking dish with parchment paper making sure some of the paper overhangs on the sides so you can lift the bars out of the dish later. Press the peanut butter mixture into the bottom in an even layer.
  • Add the chocolate chips and the last 2 Tbsp peanut butter to a bowl. Microwave for 30 seconds, then stir. Continue to microwave and stir in 15 second increments until the chocolate is fully melted and smooth.
  • Pour the melted chocolate over the peanut butter base in the baking dish and spread it smooth. Add the mini pretzels on top in even rows (I did five rows of five across).
  • Refrigerate the peanut butter bars for two hours, or until completely set. Once set, lift the bars out of the dish using the parchment paper. Use a sharp knife to cut them into squares between the pretzels. Enjoy immediately, refrigerate for later, or freeze for long term storage.

How to Make Pretzel Peanut Butter Bars – Step by Step Photos

Graham crackers in a food processor

While you can actually buy graham crackers already in crumb form, it’s going to be less expensive to make crumbs out of whole crackers. You want a very fine and even crumb for this, so a food processor is probably the best option. You need 1 cup of crumbs, which should be about 8 sheets of graham crackers.

Whiz those graham crackers until they’r every fine and even.

Peanut butter and butter in a bowl

Add 1 cup peanut butter and ½ cup butter (I used salted) to a bowl. Microwave for 30 seconds or just long enough that they’ll melt together. Avoid heating it until it’s piping hot. That will make the later steps more difficult. Stir until the mixture is even and smooth.

Graham cracker crumbs and powdered sugar added to the peanut butter

Add the graham cracker crumbs and 1 cup powdered sugar to the peanut butter mixture.

Stir until it forms an even paste-like mixture.

Line an 8×8-inch baking dish with parchment paper so that some of it sticks up the sides (this will help you remove the bars from the dish later). Spread the peanut butter mixture evenly into the bottom of the dish.

Chocolate chips and peanut butter in a bowl

Add 1.5 cups chocolate chips and 2 Tbsp peanut butter to a bowl. Microwave for 30 seconds, then stir will. Continue to microwave and stir in 15 second increments until the chocolate is melted and smooth. Avoid over heating the chocolate or it will begin to get grainy.

Mini pretzels being pressed into the melted chocolate

Press the mini-pretzels into the melted chocolate in rows. I did five rows of five across. Make sure to leave a little space between each because that is where you’ll cut your bars.

Refrigerate the peanut butter bars for at least two hours, or until they are solid. Lift them out of the dish using the sides of the parchment paper. Use a sharp knife to cut them into squares between each pretzel.

You can keep your peanut butter bars in the refrigerator for about a week, or freeze them for longer! They thaw pretty quickly at room temperature, so you can get that peanut butter chocolate fix whenever you’d like. ;)
