Mummy Cupcakes: Preheat oven to 375 degrees F (190 degrees C). Lightly butter, or line 16 muffin cups with white cupcake liners.

In a stainless steel or heatproof bowl place the cocoa powder. Pour the boiling water over the cocoa powder and stir until smooth. Set aside to cool while you make the batter.

In another bowl, whisk together the flour, baking powder, and salt.

Then in the bowl of your electric mixer, or with a hand mixer, beat the butter and sugar until light and fluffy. Add the eggs, one at a time, beating until smooth. Scrape down the sides of the bowl as needed. Beat in the vanilla extract. Add the flour mixture and beat only until incorporated. Then add the cooled cocoa mixture and stir until smooth.

Fill each muffin cup about two-thirds full with batter and bake for about 16-20 minutes or until risen, springy to the touch, and a toothpick inserted into a cupcake comes out clean. Remove from oven and place on a wire rack to cool. Once the cupcakes have completely cooled, place the frosting in a piping bag, fitted with a Wilton #47 or #48 basket weave tip, and pipe lines back and forth on the top of each cupcake. Place two candy eyes on each cupcake.

Marshmallow Cream Frosting: In the bowl of your electric mixer, or with a hand mixer, beat the butter until smooth and well blended. Beat in the vanilla extract and marshmallow creme. With the mixer on low speed, gradually beat in the sugar. Scrape down the sides of the bowl as needed. Add the cream and beat to combine. Then, on high speed, beat frosting until it is light and fluffy (about 3-5 minutes). Add more cream or confectioners sugar if necessary to get the right piping consistency.

Makes 16 cupcakes.
