A lot of of peanut butter bars are “No Bake”, like these Chocolate Peanut Butter Bars from Sally’s Baking Addiction, but our Easy Peanut Butter bars contain egg and so they do spend a little time in the oven. But, no worries, it’s still a really easy recipe! The only part that can sometimes be a little tricky is the frosting — I find that the key to avoiding lumpy frosting is to sift your confectioners sugar and then slowly mix it in! And let the bars cool before adding the frosting unless you want a huge mess.

Here’s the recipe and the full set of instructions:
