Hi, we are having a Christmas party tonight. I baked a bunch of cookies and the recipes called for lining the cookie sheets with parchment paper. I used waxed paper (I thought they were the same thing lol -apparently not). Unfortunately now all of my cookies are stuck to the paper. How can I get them off without ruining the cookies? I already tried putting them back in the oven to heat and then peeling off the paper. That didnt work. Any help would be appreciated. Thanks.
