Butterfingers have to be one of my favorite candy bars, and Blondies are one of my favorite desserts.  It only seemed natural that they come together in one glorious dessert.  This used up the last of my leftover Halloween candy, which is probably a good thing.  It is really hard to walk past, and not just grab one of those Butterfingers.

My poor family didn’t get to try these.  I had one, ok maybe two, to test of course.  Then I gave them straight to a friend.  Even my husband, who doesn’t like chocolate would have loved these.  Peanut butter base, with Butterfingers mixed in, and then topped with a Butterfinger frosting.  Pure heaven!  I debated about putting the frosting on, but in the end I am happy I did.  The first half of the one I tested, didn’t have Butterfinger in it 🙁  I decided to remedy that, the frosting would be made.

Trust me when I say that you need to try these.  I am thinking about going to buy more candy, just to make these to share with my family.  They were that good.
