Decide which design you will make (if you're making a little of each, adjust ingredient amounts accordingly).
Remove pan from oven and immediately press your Reese's or marshmallow half into the hot cookie. Begin decorating (see notes below for steps)! ENJOY.

Notes
Have all your candy unwrapped so you can press them into your cookie cups immediately when taking them out of the oven! Allow the cookie cups to sit in the pan for about 10 minutes, then use a butter knife and they should POP right out!
For the mummy: you can use either white chocolate peanut butter cups or marshmallows (for a fun fluffernutter treat). Use melted white chocolate and drizzle it on the cookie to create the scraps of cloth! Don't forget the candy eyes!
For the spider: you can use either a peanut butter cup or a rolo for these fun treats. Then press your candy eyes on top and use melted chocolate to create the legs!
For the bloody eyeballs, you can use either a white chocolate peanut butter cup or marshmallow. Then use red gel to create the bloodshot look and the big candy eyes!
