Mix the flour, xanthan gum if using, sugar, baking powder and bicarb together in a bowl

Make a well in the middle and pour in the coconut milk, cream, melted margarine, milkshake powder / liquid & strawberry essence and beat in

Add colouring if desired at this point. I used 2 tsp beetroot powder to reach this colour. Remember using unbleached flour will make your colours duller so you'll need to add extra if using that

Divide the batter between the cupcake cases

Bake for 20 minutes until well risen and set. Let cool on a wire rack

Cream the icing sugar with the margarine then mix in the milkshake flavouring. You can add dye here again if you like. Put in a piping bag and pipe swirls onto each cooled cupcake
