You will also need: 14-16 creepy crawlie decorations… in my case, I am using large gummi-figures that I found at one of the specialty food shops.
Preheat oven to 400F. Prepare a muffin pan with lines.
In the top part of a double boiler over very hot, but not simmering, water, or in a microwave at medium power, melt the chocolate. Remove from the heat or the oven, and let stand, stirring often, until cool.
Beat the butter in the bowl of a stand mixer fitted with the paddle blade on medium-high speed until smooth, about 1 minute. On low speed, beat in the confectioners’ sugar. Return the speed to medium-high and beat until light in color
and texture, about 2 minutes. Beat in the egg yolks, one at a time, scraping down the sides of the bowl. Beat in the chocolate and vanilla.
Beat the egg whites and granulated sugar in a large bowl with an electric mixer on high speed just until they form soft, shiny peaks. Do not overbeat. Stir about one fourth of the beaten whites into the chocolate mixture to lighten it, then fold in the remaining whites, leaving a few visible wisps of whites. Sift half of the flour over the chocolate mixture, and fold in with a rubber spatula. Repeat with the remaining flour.
Fill the lined muffin cups three-quarters full, being careful not to overfill. Bake until a toothpick inserted in the center of the cupcake comes out clean, about 20-22 minutes. Cool the cupcakes in the pan for 5 minutes, then transfer to a wire rack to cool completely.
For the frosting, cream butter for a few minutes in a mixer with the paddle attachment on medium speed. Turn off the mixer. Sift 3 cups powdered sugar and cocoa into the mixing bowl. Turn your mixer on the lowest speed until the sugar and cocoa are absorbed by the butter. Increase mixer speed to medium and add vanilla extract, salt, and milk/cream and beat for 3 minutes. If your frosting needs a more stiff consistency, add a little more sugar. If your frosting needs to be thinned out, add additional milk 1 tablespoon at a time.
Pipe frosting onto the cooled cupcakes and decorate with one of your decorations. Boo.
