Preheat the oven to 180°C or 350°F.
Add tahini paste, eggs, baking powder, vanilla, sweetener and cocoa powder in a large bowl. Mix until just combined. The batter should be a rich, deep brown. Don’t overmix.
Stir in the chocolate chips or chopped chocolate.
On a parchment-lined baking tray, arrange the batter into a long, thin rectangle (it will expand in the oven).
Sprinkle with sea salt on top.
Bake for 15 minutes.
Enjoy fresh out of the oven or freeze them for a deliciously cold treat!
