If you are baking the cookies immediate after rolling out the dough, preheat the oven before you start making the cookies dough to 180℃. If not skip this step.
In a large mixing bowl, beat the butter with an electric hand beater or wooden spatula until it is pale in color. Add the sugar and beat again until creamy.
Add the flavors with the egg and beat together until combined.
Add the flour and fold together to form a dough.
Wrap the dough in cling film or zip lock bag and leave in the fridge for 2 hours to firm up.
Preheat your oven at this point to 180℃. Line a baking tray with baking paper.
Roll the cookie dough 1/4 of an inch. Roll the dough between cling wrap or baking paper.
Transfer the cookie dough to the baking tray and bake for 10-12 mins until the bottom has a golden brown color and the top is dry to the touch.
Remove from the oven, let it cool for a few minutes before transferring to a wire rack to cool.
Sandwich with fillings of your choice or serve as it is.
