Line a baking sheet with wax paper that will fit in your refrigerator.
Melt 12 ounces dark or milk chocolate and 3 ounces melting white chocolate separately in different bowls. I use the microwave (10-second spurts mixing well between each). Or use a double boiler.
Spread the dark chocolate on the paper with an offset spatula, knife, or the back of a spoon. Don't make it too thick, or it will be hard to break up. Between ⅛ and ¼ inch is what you want.
Sprinkle ⅓ cup crushed plain chocolate cookies or wafers on top.
Mix orange food coloring with the melted white chocolate. Depending on your brand of coloring (mine was a powder, Dustcolor), you might need more or less to get the type of orange you want. Start small, with a pinch, mix well and add more if necessary.
Drizzle the orange chocolate across the dark rectangle, leaving streaks and not covering it completely.
Top with candy eyes before it sets.
Refrigerate for about 20 minutes until completely hardened. Depending on the thickness of the orange-colored chocolate, it might take more time to solidify.
Separate the cold chocolate rectangle carefully from the paper.
Break into pieces by hand and keep in tins with a tight lid or another airtight container.
