(this was originally a GF recipe, but they work with plain flour as well)
225g plain flour
1 tsp (5 ml) baking powder
175g caster sugar (granulated works as well)
1 tsp (5 ml) vanilla extract/flavouring
1 beaten egg
Mix flour and baking powder in a bowl. Rub in the butter. Squish it between your fingers in the flour, it's actually quite fun in my opinion. Add the sugar and mix. Add the vanilla and egg and mix into a dough. Here is where you can add chocolate, nuts, dried fruits, etc. if you want.
Bake at 190C/375F/gas mark 5 for 10-12 minutes. If baking from frozen, you may need to add an extra minute or two. Let them cool a bit on the tray before trying to get them off, or bake them on the tray with parchment paper/greaseproof paper. The paper makes it so much easier to transfer them off the pan!
The original recipe says to shape into a long roll about 5 cm diameter and wrap, then refrigerate overnight. I end up just rolling little balls of the dough and baking some, then freezing the rest of the cookie balls on a cookie sheet. Once they're frozen, toss them into a bag or container and then you can just pull out as many as you need (or want) and bake away without waiting. That is, *if* you can resist eating the frozen dough like I always end up doing...
