In a bowl, add all the dry ingredients (flour, baking soda, ground almonds, salt) and mix.

In your stand mixer or using your hand mixer, mix the butter and sugar till well blended.

Now add the egg and almond extract/essence and mix.

To this gradually add half the dry flour mixture, mix, add the milk, mix and finally the remaining flour and mix till combined well.

Now shape 1 inch balls and roll each ball in the blue sugar crystals. Place each blue sugar crystal covered ball, 2 inches apart, on parchment paper, on a cookie tray.

Once all your cookie balls are done and on the tray, play the same inside the oven to bake for 8-10 minutes.

As soon as you take the tray out of the oven, gently press in the candy to decorate the same and leave to cool.
