125 g unsalted butter, chopped, at room temperature
¾ cup caster sugar
1 tsp vanilla extract
1 egg, at room temperature
1 ½ cups self-raising flour
90 g Smarties
- Line two large oven trays with baking paper.
- Beat butter, sugar and vanilla in a small bowl of an electric mixer until light and fluffy. Beat in egg until combined. Transfer to a large bowl. Add sifted flour. Stir until combined.
- Roll 2 tablespoons of mixture into balls. Arrange 5cm apart, on prepared trays. Gently press down to flatten slightly. Press seven Smarties into the top of each cookie.
- Cook both trays at the same time, in a moderately slow oven (160C) for about 15 to 20 minutes, swapping trays halfway through, or until golden brown. Remove from oven.
- Cool cookies on trays.
