How to make this Halloween candy bark

First, make the chocolate and Oreo base

Melt 15 oz of dark chocolate using a double boiler, stirring until smooth. If you don’t have a double boiler, place a heatproof bowl over a pot of simmering water. This gentle method reduces the risk of overheating the chocolate and keeps it warm while you work.

Dark chocolate can be darkened with a touch of black food gel if you prefer a deeper color. Alternatively, you can substitute 20 oz of black candy melts for the dark chocolate if you want a consistent black base without tinting.

Crush 12 Oreos in a food processor or in a sealed bag with a rolling pin, then fold the crumbs into the melted chocolate. Spread the mixture across a parchment-lined 9″x13″ baking sheet and let it set at room temperature until firm.

Second, create the white chocolate webbing

Melt 5 oz of white chocolate in a double boiler, stirring until smooth. To recreate the irregular look of a cobweb, dollop larger amounts of white chocolate in spots, then drizzle thinner strands over the surface. Use a toothpick to pull through the wet white chocolate to form a webbed effect. Add sprinkles now if desired, then allow the white layer to set at room temperature.

Third, pipe the chocolate spiders

Melt the remaining 5 oz of dark chocolate in the double boiler and darken with black food gel if desired. For piping shapes, the chocolate needs a smooth, pipeable consistency — similar to a soft peak that will hold shape but still has a slight curl. If the chocolate is too thick, add a small amount of vegetable shortening and stir until fully incorporated. A little shortening goes a long way.

Transfer half the chocolate into a piping bag and leave the rest warm in the double boiler so it doesn’t set. Snip a larger hole and pipe dollops for spider bodies and heads, tapping the sheet lightly to smooth ridges. Put the remaining chocolate into a second bag, snip a smaller hole, and pipe legs.

To make black widows, melt 2 oz of red candy melts and pipe small eyes and the signature red hourglass on a few spiders while the chocolate is still soft.

Finally, cut and serve

Use a large knife to slice the candy bark into pieces. For clean edges, run the knife under hot water, dry it, then cut; repeat between cuts as needed. Arrange on a platter and serve at room temperature.

Tips for making spider candy bark

  • Keep utensils dry: Any water in the chocolate will cause it to seize, so make sure bowls and tools are completely dry.
  • Swap candy melts: To avoid tinting dark chocolate, use 20 oz of black candy melts instead of dark chocolate.
  • Thin thick chocolate: Add a small amount of vegetable shortening and stir until smooth to reach a pipeable consistency.
  • Make realistic webbing: Dollop larger amounts of white chocolate, then drizzle thin strands and drag a toothpick through wet chocolate to create a web look.
  • No double boiler: You can microwave in 10-second bursts, stirring between each burst, but be careful not to overheat.
  • Clean cuts: Warm your knife between cuts for neater slices.
  • Storage: Store candy bark in an airtight container in a cool, dark place for several months.
