Preheat oven to 350 degrees F and line two baking sheets with parchment paper.
In a large mixing bowl, whisk together the eggs, oil, tahini, sugar, and vanilla.
Add the flour, salt, and baking powder to the wet mixture and stir with a spatula or wooden spoon until a dough has formed. Stir in the finely chopped chocolate.
On a lightly floured surface, roll out the dough to around 1/4 inch thick and cut out circles with a cookie cutter or the top of a drinking cup. Transfer the circles to the baking sheets, roll out the remaining dough again and cut out more circles until there is no dough left.
Fill each circle of dough with a 1/2 tsp of the tahini filling then pinch together the corners to create the signature hamantaschen triangle shape.
Bake the hamantaschen for 10-12 minutes, until the edges are just turning golden brown. Transfer to a cooling rack.
While the hamantaschen cool, make the tahini ganache by melting the chocolate and tahini together either over a double boiler or in the microwave. Set aside for 5-10 minutes to cool a bit then drizzle over the hamantaschen.
Enjoy your delicious Salted Chocolate Chip Tahini Hamantaschen!
