Preheat oven to 180°C/fan 160°C/gas mark 5.
Cream together the sugar and butter in a bowl.
Add the Fate Low Protein All-Purpose Mix and the baking powder and rub together with your hands until it resembles breadcrumbs.
In a separate bowl, mix together the ProZero, egg replacer and vanilla essence.
Combine the wet and dry mixtures and stir with a spatula until smooth.
Add as much orange food colouring as desired.
Spoon the mixture evenly into the cupcake cases.
Bake in the oven on the middle tray for 25 minutes.
Remove from the oven and allow to cool.
Once cooled, mix together the icing and the food colouring until you reach the desired colour.
Pipe the icing onto the cupcakes and sprinkle the freeze-dried raspberries on top.
Place the Vitabite shards on top to resemble a bonfire.
