I havent made them yet but think they would be super easy and yummy. To SephandEmma, maybe try putting a large enough squirt of frosting in the center of the cookie so that when the kiss is pressed on it kind of mushes out around the edge, then just pipe a bow. Like I said i havent made them but that seems like it would be easier than piping it like you said. :)
Cute and easy. My 7 year old daughter enjoyed putting the hats together while I preped the frosting and piped the hats. I did melt some chocolate chips and had her dip the bottom of the kiss in the melted chips. It made it so easy to seemlessly put them together. It was difficult to pipe around such a tall, but small circle (the kiss), but they still look and taste great. I will absolutely try these again next Halloween!
