Prepare parchment paper by laying out on flat surface.

If needed trace a circle on parchment with pencil. I used a 12 inch plate as guide.

Flip parchment over so pencil doesn't get on food, you will be able to see the circle through.

Pour melted white chocolate into center of circle and smooth out to edges with off set spatula.

Next drizzle semi-sweet chocolate in a circular pattern. I used a piping bag for better control.

Next take a tooth pick and drag lines downward from out side of semi-sweet circle to inside to create the spider web look.

Next add pretzels, candy corn, toffee popcorn, toffee and sprinkles, pressing lightly so they adhere to chocolate.

Let set for at least 6 hours, this could vary depending on temperature of your room.

Break when ready to serve.
