In a small microwave bowl, microwave 1 teaspoon shortening.
Add 1/3 cup lavender chocolate melts. Stir until completely melted.
Using a tablespoon, fill 3 of the molds with 2 Tablespoons of the melted lavender chocolate.
Place an Oreo cookie on top of the melted chocolate.
Pour additional melted lavendar chocolate on top of each cookie, up to the top of the mold.
Tap the sides of each mold to release any air bubbles.
Repeat steps 1-5 using each color: orange (as shown below), green and white.
Chill for 30 minutes.
Line a large baking sheet with wax or parchment paper and set aside.
Gently pop each cookie out. They will be released from the mold very easily. Place on the lined baking sheet. (As this mold is no longer available, the cookies will not have the spider web outline)
You can purchase the spider web molds and make the candy spider webs, placing them on top of each cookie, but you can make your own webs!
Using the black and/or white sparkle gel, make 3 circles on the cookies, mimicking the webs above.
Take a toothpick and pull it from the middle to the outside of the cookie 8 times.
Tip: It's always a good idea to practice on paper before applying to cookie. It will help your confidence when you're piping on the cookie!
Place back on the baking sheet and allow cookies dry for at least 30 minutes.
