Spider cookies
Here's a simple one for the kids that's easy to make.
A few dark chocolate sandwich cookies (such as Oreos)
Pretzel sticks
Candy eyes (often found in the baking aisle)
A little melted white chocolate
Start by breaking the pretzel sticks in half and inserting them into the cream filling of each cookie to create eight legs per cookie.
Use a drop of white chocolate to attach the eyes.
