Firstly, in a food processor, I combined tahini, dates, chia seeds, hempseeds, flax meal, vanilla extract and orange extract. You may add orange zest instead of orange extract.
Secondly, I ground it well until a dough was formed and it was sticking to each other. In this step, I paused frequently to scrape the batter from all sides and grind again.
Then, I took out and lay it flat on the counter and gently pulled out the parchment paper along with the shaped dough. Lastly, I placed it on a cutting board and sliced.
