Preheat the oven to 160C/320F. Line a baking tray with baking paper.
Combine the ingredients for the cookie dough in a small mixing bowl. Mix, mix and mix until the batter is the consistency a slightly soft cookie dough. This can take 2-3+ minutes of mixing and some elbow grease - I promise it will get there. If need be, have a tiny break and then get back into it. It should hold steady on the spoon if you lift some batter into the air. Some batches I'm even able to pick the dough up and roll it into balls by hand (soft but firm is what we're going for).
Add any mix ins you plan to use and stir to combine. Use a spoon to place the dough onto the baking tray, leaving room for spread. Bake for 15-20 minutes or until the cookies are golden and crisp. Allow to cool almost totally on the tray - they firm up as they cool.
These cookies keep well in an airtight container on the bench or in the fridge for a number of days. They will become less crisp with time, but are still delicious.
