so, the main reason i made these cookies was because i wanted to use up some leftover frosting in the freezer.
recipe from Real Simple. i added all i had left for chocolate chips as well as some chopped white chocolate. i also used shortening instead of butter...because i didn't have any butter.
my favorite was the browned butter cream cheese frosting cookie sandwich. also, i haven't tried the strawberry butter-cream or chocolate ganache sandwich cookies because i probably ate about five cookies before they made it into the oven so...that's enough for one night. maybe.
