Start by lining a baking sheet with parchment paper, or foil and spray with non-stick cooking spray (only use the cooking spray if using foil).
Place chocolate in a microwave safe bowl. Microwave chocolate in 30 second intervals, stirring every 30 seconds until melted. (Mine was ready in 1 minute, 30 seconds).
Add the bran twigs to the melted chocolate, and stir until well combined. (Add optional sweetener here if you desire)
To assemble spiders, place 6 pretzel stick-halves on prepared baking sheet (3 pretzel halfs on each side). With a large spoon, scoop up about 2 tbs worth of mixture onto parchment paper over the 6 pretzels (this is what makes up the body of the spider). Add 2 white chocolate chips for eyes.
Place baking sheet in the freezer for about 5-10 minutes to set the chocolate. Enjoy!
