Sieve the almond flour into a bowl then combine it with the sweetener, salt, vanilla, almond essence, baking powder (optional), and butter. Stir in ground almonds and mix, making sure to scrape off any dough sticking on the bowl. Next, divide the dough into 5 pieces each about 4-5cm. Wrap each in saran wrap or cling film and allow to cool in the fridge.
