Ingredients

• 125 g butter, softened
• 1 cup caster sugar
• 1 egg, at room temperature
• 1/2 teaspoon vanilla essence
• 1 1/2 cups self-raising flour
• 1/2 cup custard powder
• 80 g white chocolate, roughly chopped

Instructions

1. Preheat oven to 180C and line 2 baking trays with baking paper.

2. Using an electric mixer, cream butter and sugar until light and fluffy. Add egg and vanilla and beat until well combined.

3. Sift flour and custard powder together over butter mixture. Add white chocolate and stir until mixture forms a soft dough.

4. Roll tablespoonfuls of mixture into balls and place on prepared trays, allowing room for spreading. Using a fork, press dough to flatten slightly.

5. Bake for 10 to 12 minutes or until golden. Stand on trays for 5 minutes then transfer to a wire rack to cool.
