Start by placing your butter, sugar, and cream cheese into a mixing bowl. Beat until smooth.
Add your powdered sugar, cocoa, and mini chocolate chips. Knead into a ball until completely combined.
Refrigerate for 2 hours. (If the mixture is too sticky you can add one cup of powdered sugar.)
Separate into a small ball and a large ball.
Roll each ball in chocolate sprinkles and set them on a plate, creating your spider body.
Add the candy eyes and pretzels for legs.
Serve and enjoy!
