Whether you dread it, look forward to it, or are indifferent to it, it is back-to-school time! At this time of year, I like to feature a recipe using peanut butter. As a grade schooler, our neighborhood school allowed those within walking distance of the school to go home for lunch. Living directly across the street from the elementary school, I headed home on most school days for a peanut butter sandwich at lunchtime. I ate quickly and hurried back across the street in time to buy ice cream for dessert in the school lunchroom before heading outside for recess with my classmates.
Peanut butter is still a staple of my lunches when I need a portable, non-perishable lunch. We always have a jar in the kitchen cabinets and a backup jar in the pantry. I also use this versatile condiment frequently while baking. Peanut butter is the focal point of this recipe for back-to-school treats.
These peanut butter shortbread bars have a rich and crumbly dense and sweet shortbread base. Shortbread is traditionally made with butter, sugar, and flour. Here, peanut butter is added to the biscuit base, adding delicious nutty flavor. What really makes these bars special is the chocolatey peanut butter icing. With some additional chopped peanuts topping the bars off, these are a special treat for so much more than just the back-to-school season!
