Miniature rainbow birthday cake cupcake topper

Roll out each of the sugarpaste colours to the thickness of a £1 coin, then cut out one of each colour and four in white.

Stack the circles, layering one white circle between each colour and sticking them together with water.

Roll the tower gently to blend the sugarpaste together slightly.

Take the bulb tool and give texture to the coloured sugarpaste layers to create a sponge-like texture with little holes.

Carefully cut a slice out of the cake with the palette knife. Roll small balls of white sugarpaste, then paint a circle of water around the top of the cake and stick them on top.

Paint the circles of sugarpaste with a dot of water and attach sprinkles of choice.

Take 2 colours of sugarpaste and roll into tubes. Attach together at one end and twist gently, then trim accordingly. Leave to dry for 30 minutes. Shape a small ball of yellow sugarpaste into a teardrop shape.

Make a small dent in the top of the cake in the centre, then brush on some water and attach the candle upright.

Paint the end of the candle with water, then attach the yellow flame to finish.
