I wish I had a video compilation of people’s reactions when they taste these peanut butter bars. In my experience their eyes get wide and they exclaim something like, “Oh my god!” Then they ask me for the recipe. These are seriously the most delicious and addictive treats I’ve ever had. Once I start eating them I have trouble stopping. One time back in high school I received a marriage proposal when a friend of mine tried one. I think I can safely say that if you like peanut butter, you’re going to love these peanut butter bars. I first wrote about them back in 2011, but I halved the recipe and it just wasn’t the same. But since I needed a boatload of goodies for holiday parties and other get-togethers this week I whipped up a full batch (a whole jelly roll pan’s worth) and served them on three different occasions. I ate more than my fair share too! Didn’t I say they’re addictive?
1 c (2 sticks) melted butter
16 oz (1 jar) chunky peanut butter
1 1/2 c graham cracker crumbs
1 lb powdered sugar
8 oz Hershey bar (I used two 4.4 oz bars)
The original recipe, which is handwritten on an index card in my mom’s recipe organizer, simply says “mix together all ingredients except Hershey bar.” But I’ve found that it works best if you stir together the melted butter, peanut butter, and graham cracker crumbs in a large bowl first. You can just use a wooden spoon for this. When those ingredients are thoroughly mixed add about half of the powdered sugar and stir to combine. At this point you’re going to wonder how in the heck you’ll ever be able to get the remaining powdered sugar to mix in, but it will work. Dump the rest of the powdered sugar into the bowl and stir in as much as possible with the wooden spoon. I always have to resort to using my hands near the end before the mixture gets so thick. I promise if you work at it long enough you can get all of the powdered sugar incorporated! Press the peanut butter mixture into the bottom of a large jelly roll pan (mine is 15x11x1″), using whatever you can find to smooth it out (a rolling pin or round glass works best, but I used the bottom of a measuring cup).
In a small microwave-safe bowl, melt the Hershey’s chocolate. This should take about 1-2 minutes on high. Spread the melted chocolate evenly over the peanut butter mixture with a spatula. Put the whole pan in the refrigerator to cool. Wait until the chocolate has solidified to slice into squares. Enjoy!
