I baked up a bunch of cookies for a Halloween party today. First were some little cookies shaped like candy corn. Here's a link to that recipe. They were easy to make, and people really liked them. Rather than using candy melts, I just used white chocolate with a bit of yellow food coloring. Just a tip, if you want to use white chocolate, be sure to get a bar of chocolate, or white chocolate specifically for melting. Most white chocolate chips won't melt right, as they're meant to hold their shape when heated.
I also made Witches' Boom cookies. I decided on a smaller version, using mini pretzel rods and only about two teaspoons of dough per cookie.
