They were inside a box of Duff Goldman's Blondie brownie mix which I bought this Spring. I ended up tossing out the dough. It was so thick I couldn't spread it into my square pan. I thought I would at least keep the chocolate morsels which was included in the brownie mix. The expiration date on the box is August 31, 2016.
