Lay the 2 halves of each cookie out on the parchment.
Grab your sucker sticks and place them over the cream side of the cookie, about ¾ of the way up. Give it a little push, and then add your cookie top. Smush the 2 sides together by placing pressure in the center of the cookie, right over the sucker stick. If you push on the sides of the cookie, it will most likely break. Do all your Oreos like this until you have the desired amount.
In a double boiler on the stove, your candy melts. Don’t use the microwave method for these. You are going to need to reheat your chocolate at least once throughout the process. It's easier to have the hot water ready to go.
** Side note:. Make sure all bowls and utensils are bone dry. Chocolate and water do not mix. If you put water in it, it will seize and be useless. If you are coloring your candy melts, make sure you use candy colors. Don't use regular food coloring. It is water-based and will ruin your chocolate. Either buy pre-colored candy melts or buy candy coloring.
When your chocolate is ready to go, start dipping. Be as quick as you can; don’t doddle in the chocolate, or the heat will melt the cream in the cookie and it will fall apart. A quick in and out, then tap the stick on the bowl to get the excess chocolate off. Lay the dipped cookie on your parchment paper.
After you have dipped 10 cookies, place your chocolate back on your double boiler (low heat). Put your candy eyeballs on your cookie pops. You have a relatively long working time with candy melts; just make sure the chocolate is still wet when you place the eyes.
Keep going until all the pieces are dipped and have their eyes on them.
