Line a baking sheet with parchment paper or a silicone mat. This keeps the bark from sticking and makes cleanup simple.

Place white candy melts in a microwave-safe bowl. Heat in 30-second bursts, stirring after each, until completely melted and smooth.

Pour the melted white candy onto your prepared baking sheet. Use a spatula to smooth it into an even layer, about 1/4 inch thick.

Melt the orange, purple, green, and black candy melts in separate bowls. Use the same microwave method as the white melts.

Once melted, spoon each colored candy into a small piping bag or a zip-top plastic bag with a corner snipped off. This gives you more control over the swirl design and makes the process less messy.

Use your piping bags to draw even rows of colored candy melts across the white layer. Don’t worry about perfect lines - the fun is in the swirls.

Use a toothpick or skewer to drag through the colors, blending and swirling to create a marbled Halloween pattern. Work quickly while the base is still soft.

Sprinkle the candy corn, pretzel pieces, and Halloween sprinkles over the swirled bark. Press toppings down gently so they stick before the bark sets.

Let the bark sit at room temperature for 1–2 hours until firm. To speed things up, place it in the refrigerator for about 30 minutes.

Once fully set, break into pieces using your hands or a sharp knife. Big or small pieces work great - just go with what feels fun.
