  2. Step 2

    Divide icing into 5 equal portions, and tint with varying pastel colours of pink, green, yellow, blue and purple (blue and red) kneading until smooth and colour is evenly distributed. Icing may become sticky with the addition of colour, if this happens, simply dust icing with more icing sugar mixture and knead until no longer sticky.

  3. Step 3

    Roll each colour out to 3-4mm thick. Using a sharp knife or cookie cutter, cut out triangle shapes 3-4cm wide. Set aside on baking paper. Remove cake from fridge, brush the back of each triangle with a small amount of water and adhere to cake to create bunting.

Recipe notes: Once bunting has been added, the cake cannot be refrigerated. Ready to Roll Icing will go soggy and may slide off your cake or leach colour into the buttercream icing.
