I use pretzels, M & Ms, sprinkles, and candy eyeballs in my bark, but you can also mix in these tasty toppings: -Candy corn (I personally am not a fan, but it would look great in Halloween holiday bark!) -Pumpkin-shaped candy -Black licorice pieces -Reese's Peanut Butter Cups -Nuts (almonds, cashews, or pistachios would work well) -Popcorn - either regular or Halloween-colored popcorn
