Step 1

Line a 7x11 baking pan with foil or parchment paper. Set aside.

Step 2

In a double boiler: melt the dark chocolate over medium-low heat stirring constantly. Remove from the heat once the chocolate is silky smooth. - OR - In the microwave: microwave on high for 15 - 30 second bursts, stirring between bursts, until silky smooth. Repeat with the white chocolate.

Step 3

Once the dark chocolate is melted, pour it into the prepared pan. Spread it out to cover the bottom, making the top as smooth as possible.

Step 4

Load the melted white chocolate into a piping bag. Cut off the very tip of the bag to create an opening just large enough to squeeze out the white chocolate.

Step 5

Starting with a white center dot, make concentric circles randomly over the dark chocolate. Circle 3 - 4 layers deep work well. Create both big and small circle sets and take them all the way to the edges.

Step 6

Use a toothpick to lightly feather the white chocolate through the dark chocolate. Start in the solid center and gently drag the toothpick out to the edge

Step 7

Go around the circles pulling them out to make web designs, there is no wrong way to do the webs, just have fun with it.

Step 8

Once you get it how you like it gently press the spider rings into the webs wherever you like.

Step 9

Allow to cool completely to set.

Step 10

To serve, cut with a sharp knife. Store at room temperature in an airtight container.
