Peanut butter cookie bars are topped with a layer of whipped peanut butter frosting, then a layer of chocolate frosting in this tasty treat that’s perfect for parties and potlucks.
If you love peanut butter and chocolate together, then you’re going to love these easy to make Frosted Peanut Butter Cookie Bars.
I love a good peanut butter cookie! I love it even more with chocolate frosting. And I especially love a delicious cookie in bar form.
Baking one big pan of cookies, rather than scooping out dozens of individual cookies, really appeals to the busy me that loves a good shortcut in the kitchen.
And since these Sugar Cookie Bars are a favorite with friends and family, I figured I couldn’t go wrong with a peanut butter and chocolate version.
I was not disappointed. And neither were the friends and family we shared these cookies with.
On of the best things about this recipe is that it does make plenty to share with friends. Which means it’s perfect for potlucks, parties and school bake sales.
And yes, these cookies do have two layers of frosting–peanut butter and chocolate. I suppose you could just pick one, although I can’t imagine why you’d want to leave out any frosting!
Like I said, if you love chocolate and peanut butter, then this is the recipe for you.
You can use chunky peanut butter if you prefer a little crunch. Personally, I’d go with chunky, but since everyone else in my family prefers smooth peanut butter, that’s what I use.
If you want to make a big batch of peanut butter cookies, but do it quickly and efficiently, then you’ve got to try these Frosted Peanut Butter Cookie Bars.
