Place an Oreo near the center of each frosted sugar cookie.
Use black icing to draw four lines on each side of your Oreos to make the spiders legs.
Stick the back side of your candy eye into a bit of leftover frosting and stick on your Oreo to make the spiders eyes.
*Optional* Sprinkle leftover cookies with Halloween sprinkles. Enjoy!

Notes
If short on time you can totally use a sugar cookie mix or even store bought sugar cookies, then quickly spruce them up with the spider embellishments!
