To make the daffodils, roll out the yellow sugar paste icing and using a flower cutter, cut out flower shapes. Roll a small ball of yellow sugar paste and using a cocktail stick or skewer, poke a hole in the centre, rotating the stick around slightly to make the hole bigger. This will form the centre of your daffodil. Lightly brush the centre of the flower shape with water and gently secure the flower centre to it. Place on top of each cupcake.
