• Peanut Butter – Creamy peanut butter is the star flavor in these no-bake bars..

• Graham Crackers – Finely ground graham cracker crumbs combine with the peanut butter to stabilize the bars. They also add a slightly chewy texture.

• Chocolate Topping – Semi-sweet chocolate chips, peanut butter baking chips and peanut butter.
• Garnish – Chopped peanuts add texture and crunch.

How to Make the No-Bake Peanut Butter Bars Recipe

• Chill Peanut Butter Mixture – Press evenly into 13×9-inch pan. Place into the refrigerator for 15 minutes.

Kitchen Equipment to Make Reese’s Peanut Butter Bars

• 13×9-inch size pan, cake pan or baking dish.
• Medium bowl.
• Measuring cups and measuring spoons.
• Nut chopper or sharp knife and chopping board.
• Double boiler to melt the chocolate. You could also use a large microwave-safe bowl.
• Offset spatula for spreading the warm melted chocolate on top.

Recipe Variations, Tips and Substitutions

• Chocolate Chips – You can use your favorite brand of baking chips for this recipe. I recommend Ghiradelli as it tends to melt smoothly.
• Butter – You can use salted or unsalted butter in this recipe. Don’t sweat the small stuff.
• Peanut Butter – You could experiment with alternative nut butters, such as almond butter.
• Double Boiler Substitution – If you don’t have a double boiler you can make your own. Fit a stainless steel bowl or tempered glass bowl over 1 inch of simmering water. Be certain that the water doesn’t touch the bottom of the bowl. Let sit until the chocolate chips and peanut butter chips are completely melted. Stir the baking chips and peanut butter periodically until the mixture is completely smooth.
• Parchment Paper – To lift the chocolate peanut bars from the pan for slicing, you could line the pan with two long pieces of parchment paper. Leave around a 2-inch overhang to form the handles for lifting the bars from the pan.
• Topping Variations – You can use all semi sweet chocolate chips or all peanut butter baking chips for the topping instead of a combination of the two. This won’t change the amount, only the flavor. You may also try replacing the peanut butter chips with butterscotch chips for a slightly different flavor profile.

Best Peanut Butter to Use

• Chunky or Smooth Peanut Butter – You can use chunky peanut butter in this recipe in a pinch, but creamy really does work best. Chunky peanut butter won’t taste different, but it does change the texture and I find it to be drier. This is one instance when the ingredients are so simple you should make as few changes as possible.
• Best Brand of Peanut Butter – The best brand of peanut butter to use, is your personal favorite. I use Jif peanut butter for this recipe but you could use Skippy, Peter Pan or a private store brand that you enjoy.

Storage and Leftovers

• Leftovers – Store leftover No-Bake Peanut Butter Bars chilled in the refrigerator in an airtight container, covered with aluminum foil or plastic wrap for up to 1 week.
• Freezer – You can freeze these bars for up to 3 months. When stacking, separate layers with wax paper to prevent them from sticking together. Thaw in the fridge and enjoy.
