I found this no-bake recipe on Taste of Home. While it isn’t overly heart-healthy, when noshed on in moderation it isn’t terrible. It also stores for at least 10-days in an air-tight container.
The key is to first fully line a 13×9 inch pan with foil, allowing a good two inches of foil to fall over all the sides; the foil will act as handles to remove the bar from the pan.
Pour out 1 and ½ cups of pretzels and save for decorating the bars. Pulverize the rest of the pretzels in a food processor, blender, or under a rolling pin.
Mix 1 and ½ cups melted butter, 1 and ½ cups peanut butter, 3 cups confectioners’ sugar, and the pulverized pretzels. Smoosh the mixture in an even layer in the foil-lined pan.
Microwave two bags (4 cups) of chocolate chips with two tablespoons of shortening or butter. Stir every 15 seconds or so – you want it to be shiny and soft, and it will take a minute or less. The recipe called for half this amount, and it was barely enough to cover half the pan, so use the full four cups of chocolate. Spread the melted chocolate over the first pretzel layer, and cover that with the reserved pretzels, crumbled.
Refrigerate for an hour or so, remove from the pan, and slice it into bars (a little of this goes a long way, so smallish bars).
