First, assemble your ingredients. To make the meringue, you will need two egg whites at room temperature, 1/4 tsp cream of tartar, and 1/2 cup granulated sugar. I prefer to use superfine sugar, as it dissolves quickly and does not produce a grainy texture. If you don't have superfine sugar, you can place regular sugar in a blender and process it for about 20 seconds to create superfine sugar.
In addition to the ingredients for the meringue, you will need 1/4 cup white chocolate or candy coating, 1/4 cup cocoa powder, an electric mixer with a whisk attachment, two baking sheets covered with parchment paper, and a pastry bag fitted with a coupler or a 1/2-inch round tip.
