I got the idea from my Blackberry Pie Bars. For these I used a triple berry jam that I picked up from the store. You could totally make it from scratch. The peanut butter cookie dough I got from one of my favorite dessert bloggers, Crazy for Crust. I topped these babies with some extra creamy peanut butter frosting and sugared berries. You can omit sugaring the berries, but the combination of the chewy peanut butter cookie bars and the crunch from the sugared berries is fantastic.
