Millionaire Shortbread? Let’s Make That Billionaire Bars…

Do you need a treat? Of course you do! I love classic Millionaire Bars with a shortbread layer, a rich caramel layer, and fudgy chocolate on top. They are wonderfully indulgent and absolutely make you feel like you are living luxuriously! But believe it or not, I have figured out how to make gooey chocolate caramel cookie bars even more amazing. This recipe should be called Billionaire Bars, because we have added an all-American ingredient that is so beloved, it’s become a multi-billion-dollar industry… Peanut Butter. Let’s be honest, peanut butter makes everything better. Am I right?!?

While these cookie bars have more ingredients than traditional Millionaire Shortbread Bars, they are just as easy to make. Instead of creating unnecessary layers and steps, I’ve turned the classic caramel layer into a caramel peanut butter fudge. The result is this fantastic recipe for Caramel Peanut Butter Cookie Bars. They are velvety-sweet, perfectly nutty, and a must-make to cure your next sweet tooth craving!
