Get out a cookie sheet and cover with wax paper. Melt the Vanilla Almond Bark (otherwise known as Vanilla Flavored Candy Coating) in a microwave safe bowl according to the package instructions. Stir the Almond Bark until smooth.
Spread out the melted Vanilla Almond Bark onto your wax paper on the cookie sheet. Use a rubber spatula to spread the bark out smoothly. Shape into a rectangle and smooth out to be about 1/4 of an inch thick.
Press Milk Duds into the melted candy coating and space about every 2-3 inches apart or sporadically. Press broken pretzel pieces into the melted Almond Bark. Shake sprinkles over the top of everything.
Take a tooth pick and dip the end into the melted Vanilla Almond Bark. Touch the tooth pick to each Milk Dud and create two "spider eyes".
Set in refrigerator for at least 30 minutes until the Vanilla Almond Bark is completely set up. Break the bark into small pieces. Break it around the Spiders so you have a Spider on each piece of bark. Serve to your guests or store in an air tight container.
*Tips: Feel free to add other toppings or use this recipe to make another version of holiday bark.
