In a bowl, combine the dry ingredients: all-purpose flour (140 gms), baking powder (1/2 tsp), baking soda (1/2 tsp), and salt (1/4th tsp) with a whisk.
In a stand mixer or a bowl with electric mixer, add the softened butter* (113 gms) and sugar (150 gms), and cream together on high speed for 2 minutes, until the sugar is well incorporated into the butter. The mixture should be pale and creamy.
Add the shredded kataifi dough (50 gms) into the butter mix and beat in high speed for 1 minute, until it’s well combined.
Next, add the room temperature egg* (1), and vanilla essence (1 tsp) into the butter mixture and beat on medium-high speed until it’s all well combined and there is no liquid remaining in the batter.
With the mixture on low, add the prepared dry ingredients into the batter and keep mixing until everything is well incorporated and there are no streaks of flour remaining. You will end up with a creamy, thick cookie dough at the end.
Wrap the dough in cling film and refrigerate for 8-10 hours.*
