1 Cake mix
1 pkg Green Jell-O prepared
Black frosting
8 Licorice sticks
8 Gumdrops

Take your average cake mix. Bake it up in 2 metal bowls,1 bigger than the other.
Once un-molded, cut the bigger one (the "body") in half, horizontally. CAREFULLY scoop out an adequate cavity in each half. FILL with well-whipped set green Jell-O, and reattach the halves. Frost black, arrange on serving platter. Use licorice sticks as legs. Use 2 BIG green gumdrops and 6 little ones as eyes. When the cake is cut into, it spurts green goop, just like a real spider when stepped on.
