I made these for a birthday party last fall. They were a hit! Just take a glazed donut hole, smear peanut butter (or chocolate frosting if you have an allergy) on the top part of the hole. Dip the covered part into toffee pieces (I bought Heath toffee bits) and then stick a half of a pretzel stick in the top for the "stem". Tip: twist the pretzel into the "acorn" versus stabbing it in so as to not deflate the donut. Voila! Enjoy!
