Preheat the oven to 190°c. Place paper cupcake pans in the cupcake form.
Sift the flour, cocoa, baking soda and salt into a bowl. Add the sugar and stir well. Add the eggs, buttermilk, melted butter, vanilla essence and food colouring and beat until smooth. The mixture will be quite thick and dark
Pour in the coffee and stir in carefully with a spatula until the texture of the batter is even. It will be quite runny.
Fill the cupcake pans with batter until they are two-thirds full. Bake for 20-24 minutes. Allow to cool before frosting.
For the frosting
Beat the margarine until soft. Add the cocoa and icing sugar and beat to combine.
Add the splash of milk and pinch and combine until you reach a good consistency. At this stage, the frosting will be quite dark and thick. Continue beating on high for a minute and it will become paler and fluffier.
Add the food colouring and mix the desired colour is met.
Once the cupcakes have cooled, spread the frosting onto the cake using a cake icing spatula
For the decoration
Dust a flat surface with icing sugar and roll out the fondant until it is about 2mm thick (less than 1/8"). Cut the fondant into strips the width of the cupcake. If you like, you can make indents in some or cut ends into whisps to look like frayed bandages.
Lie the fondant strips on the cupcake, some overlapping some not, to look like bandages on a mummy. Leave a slit for the eyes. Trim any excess fondant with a knife. Add two of the eyes to the slit and you are finished.
Notes
See our tips above - save time by using remade cupcakes and/or frosting or a cake mix. If you can't find remade fondant or candy eyes, see our tips above for how to make your own.
