Preheat your oven to 350°F (175°C). Combine brownie mix with eggs, oil, and water. Pour into a greased baking pan and bake for 25-30 minutes. Let cool.

Cut cooled brownies into squares. Drizzle warmed caramel sauce over them.

Cut black licorice into four segments per spider, inserting two segments into each brownie piece for legs.

Press two candy eyes onto each brownie square.

Drizzle red gel icing over the spiders for decoration. Sprinkle crushed Oreos on top for an eerie effect.

Use festive toothpicks to hold the spiders together and serve on a decorated table.
