Pre-heat the over to 180 degrees/Fan 160 degrees/Gas 4. Put muffin cases into a 12-hole muffin tin, to keep a good shape as they bake.
Measure all the cupcake ingredients into a large bowl and beat until blended and smooth. Once the mixture is mixed, separate the mixture between three bowls, then add your food gel to each bowl then mix the food colouring in. Add more food gel until you get your desired colour. Spoon your mixtures in to the cake cases and bake in the pre-heated oven for about 20-25 minutes.
While your cupcakes are cooking, get some white fondant and add a few drops of black food gel to a little bit of fondant, Mix in until all the same colour...you may need to add more to get it black instead of grey.
To make your eyes for the mummies, get your white fondant and roll it out until its an even thickness. Use a cutter that is no bigger than a five pence piece, I used a piping nozzle for the white bit of the eye and then a small piping nozzle end for the pupil. You will need 24 white bits and 24 pupils, I made the pupils using the black fondant. Once you have done your eyes, just put them to one side. Lift paper cases out of the tin and cool cakes on a wire rack until completely cold before icing.
Once your cakes have risen and gone a nice golden brown take them out of the oven and lift the paper cases out of the tin and cool cakes on a wire rack until completely cold before icing.
