Instructions

Step 1
Preheat oven to 180°C/160°C fan-forced. Grease a 9.6cm-deep, 20cm (base) round loose-based cake pan. Line base and sides with baking paper.
Step 2
Make packet cakes following packet directions or homemade cakes (see related recipe). Spread into prepared pan. Bake for 1 hour or until cooked through. Stand in pan for 5 minutes. Turn out onto a wire rack to cool completely.
Step 3
Make icing: Using an electric mixer, beat butter in a bowl until pale. Gradually add icing sugar mixture and milk, beating constantly until combined. Tint icing green.
Step 4
Place sugar in a snap-lock bag. Add 2 drops green colouring. Seal bag. Shake, scrunching with hands to distribute colour evenly.
Step 5
Using a serrated knife, level top of cake if necessary. Place, cut-side down, on board. Spread top and side of cake with icing. Cut Flakes into uneven pieces (see tip). Using picture as a guide, position Flake pieces around cake to form a fence. Sprinkle cake with green sugar. Position Curly Wurly on cake to form a gate.
