Crumble the baked and cooled chocolate cake into a large mixing bowl.
Add the frosting gradually and mix until the mixture holds together when pressed.
Take a small amount of cake mixture and shape it into a rough hand, rolling smaller pieces for fingers and attaching them to form a creepy hand shape.
Insert a lollipop stick into the base of each hand.
Place shaped cake hands onto a parchment-lined baking sheet and freeze for 15–30 minutes until firm.
In a microwave-safe bowl, melt white candy melts in 30-second intervals, stirring between each.
Add green food coloring to achieve a zombie-like shade. Stir well.
Dip each frozen cake hand into the melted green coating, tapping off the excess.
Stand the pops upright in a foam block or cup until set.
Once dry, use black icing gel to draw fingernails and stitches.
Add red gel icing to mimic blood at the fingertips or wrist area.
Optional: Use mini chocolate chips or toothpicks to add texture like scars or wounds.
Let all decorations dry completely before serving.
