In a bowl, mix together all your dry ingredients: flour, baking powder and salt.
In a mug, stir together the tahini, honey and a drop of vanilla. Transfer in your dry ingredients and mix until you get a smooth and non-sticky dough.
If you think the dough is too wet, add a bit of flour.
Use a shallow plate for the sesame seeds. Form small, walnut size balls of dough and roll them in sesame and flatten between your palms. You normally get approximately 22-25 biscuits.
Place on a lined baking tray and bake in a preheated oven at 180C for 8-10 minutes, until the bottoms are golden.
