200gm butter, softened at room temperature
150gm icing sugar
2 TB milk powder
1 large egg
310gm all purpose flour
1 tspn vanilla essence/extract
(1) cream butter & sugar till fluffy pale then add in egg & vanilla essence and whisk till cooperated.
(2) now, fold in flour & milk powder till soft dough is formed.
(3) once its ready, fill in pipping bag with soft dough and press to form a circle onto baking tray lined with parchment paper. I used silicon sheet. Then keep refrigerated for 10-15 minutes or till set.
(6) finally, bake at preheated oven 180'C -185'C for about 20 minutes or till cookies became crunchy, not overly brown. Do watch out the temperature.
