Place the dry ingredients into a large mixing bowl and rub in the butter until it has a breadcrumb consistency.
Add the light brown sugar and stir thoroughly.
Next, make a well in the centre of the mix and add the beaten eggs and black treacle.
Stir until it makes a firm dough. If the mixture doesn’t form a dough easily – add a little milk at a time, kneading and adding more milk if necessary.
Place the dough on a lightly floured surface and roll it out until it is around 5mm thick.
Using a snowflake cookie cutter cut out several shapes from the dough.
Make the leftover dough into a ball and roll out again. Repeat until the dough is used up.
Put the snowflakes onto a greased or lined baking tray and bake in the oven for 7- 10 minutes until light golden brown.
Remove and cool on a rack.
Icing
Using the stand mixer, combine the egg whites, cream of tartar, vanilla and icing sugar and mix until combined and stiff peaks form.
Scoop out and decorate using a spoon or piping bag as you want.
Add sprinkles, sugar crystals, balls or snowflakes to finish off.
