Use a very small two bite cupcakes tray. Use any size tray or cupcake paper you want though. Make the cake by putting the flour, cocoa, baking soda, salt and sugar into the bowl and mixing well in a machine or by hand, breaking up all the lumps and mixing well.
Mix the eggs, oil, vanilla, buttermilk and vinegar till combined, then mix the wet and the dry mixtures together and beat till smooth
Pour this into the moulds ( always greased and lined with baking paper) or cupcake wrappers a little higher than 3/4 of the way up.
Bake for 15 minutes or till just cooked in the centre. Cool several minutes in the pan before turning out. Chill for an hour or two or overnight.
Make the ganache by warming the cream , then add the chocolate and stir till smooth. Spread this onto the cakes and let them dry for a bit. Minw went onto mini cake bases made from cardboard.
Sprinkle a little sifted icing sugar onto a bench, and roll out the black icing. Measure your cupcake from one side over to the next and cut a circle with that diameter. Using a palette knife under the icing to pick it up from the table drape it over the cake and smooth down, cutting off any excess. a cake this small is not hard to handle, but make sure you have a couple of extras as the first may not look great.
Continue with each tiny cake till the are finished.
Decorate however you like, using the edible glue.
