What you need:

• 200g unsalted butter, at room temperature, chopped
• ½ cup icing sugar mixture
• 1 teaspoon vanilla extract
• 1 egg
• 2 ½ cups plain flour
• Pink writing icing pen and pink sprinkles, to decorate

What to do:

1. Preheat oven to 160C, fan forced. Grease and line three large oven trays with baking paper.
2. Beat butter, sugar and vanilla in a small bowl of an electric mixer until light and fluffy. Add egg. Beat until combined. Transfer to a large bowl.
3. Add sifted flour. Stir until mixture comes together. Turn out onto a clean bench.
4. Divide into two equal portions. Shape each portion into a round. Wrap in plastic wrap. Refrigerate for 30 minutes, or until firm enough to roll out.
5. One at a time, roll out each portion of dough between two sheets of baking paper until ½cm thick. Using a 7cm square cutter, cut out 22 shapes, pressing un-used dough together and re-rolling as necessary.
6. Using a small knife, cut one corner from each square to make a shield shape. Place on prepared trays, 3cm apart.
7. Ask an adult to help you put trays in oven. Cook for about 15 to 18 minutes, or until lightly golden. Stand 5 minutes, on trays before transferring to a wire rack to cool.
8. Decorate biscuits with writing gel and pink sprinkles.

Tip: Biscuits can be made up to one week ahead. Store in an airtight container.
