2 oz unsalted butter, softened
1/2 cup caster sugar
2 eggwhites, at room temperature
1/3 cup plain flour
45 messages on 1 x 2 inch pieces of paper
Preheat oven to 350 F. Place butter and sugar in a bowl. Using a wooden spoon, combine well. Add eggwhites, 1 at a time, stirring until smooth. Stir in flour and a pinch of salt until smooth.
Using an 3 inch pastry cutter as a guide, trace 4 circles, 1.5 inch apart, on to a sheet of baking paper. Flip paper over and place on a greased oven tray. Using a metric measuring spoon, spoon a slightly rounded tsp of mixture on to each circle. Use the back of a spoon to spread batter to fill circles.
Bake for 6-7 minutes or until cookies begin to brown around edges. Working quickly, slide a spatula under each cookie to loosen, then place a message on top of each. Fold hot biscuits in half to enclose, pressing edges together, then bend in half the other way, over the edge of a glass, to create crescent shapes. Hold for a few seconds. Place on a wire rack to cool.
Repeat with remaining batter. Store in an airtight container for up to 5 days.
