Preheat the oven to 175°C fan (347°F).
Whip the butter and sugars together in a medium bowl for 3-4 minutes until creamy. I use a hand mixer for this.
Add the egg, vanilla, and maple syrup. Whip again until incorporated.
Pour in the dry ingredients.
Beat on low until a dough forms (it will be on the sticky side).
Measure the cookie dough into 10-gram balls.
Roll them and space them out on a lined baking sheet (I had 16 on mine).
Bake for 5-6 minutes.
Immediately, flatten them with a cookie stamp or the bottom of a glass (in this case, use a small piece of parchment paper so they don't stick).
Let the cookies cool 1-2 minutes on the baking sheet, then transfer them to a wire rack.
Roll the remaining dough into balls and bake them the same way.
