I don’t know about you, but I strongly believe that peanut butter belongs in (almost) everything. A friend of mine asked me to create a recipe that was full of peanut butter, she was my flavor tester and LOVED these Peanut Butter Blondies.

FAQS:
How do I store these peanut butter blondies?
The frosting is made out of butter mostly so if they’re kept at a temperature higher than 72 F, they will begin to become melty. I recommend keeping them in the refrigerator in an airtight container or ziploc bag. Or keep them in a cabinet if your home is consistently at 71 F or lower.
Can this recipe be double/triple or halved? (how to/what not to do/why)
I have not tried doubling or tripling this recipe, but if you do decide to do so, I would recommend making this recipe in two or three batches. Halving the recipe would work, but the size of the pan would need to be reduced to an 8×8 or 9×9 pan versus a 9×13.
Can this recipe be gluten-free/vegan or can any of the ingredients be substituted for other dietary restrictions?
Unfortunately, it is not my specialty. However, there are many bloggers who specialize in gluten-free, vegan, nut-free, dairy-free, etc. desserts and I recommend giving them a try!
