Preheat the oven to 350° f
Soak the medjool dates in hot water for five minutes or until soft. Drain and mash the dates with a fork till the consistency resembles a jam. Set aside.
In a bowl, combine all the dry ingredients and then add the mashed dates, milk, honey, and the tahini. Use your fork to break up any big clumps, if there are any.
Fold in the chopped chocolate and transfer to a skillet or a greased 8x8-inch pan, spread out, and smooth the top with a spatula.
Bake for about 20 minutes, or until a knife inserted in the middle comes out with moist crumbs and the edges begin to pull slightly away from the pan. Cool the brownies on a wire rack for 5-10 min.
While the brownie cools, scoop out the cream from the can of coconut milk -microwave for 1 minute. Pour over chocolate chips and let sit for 2-3 min before stirring. Spread the ganache over the brownies.
With a spoon, dollop the reserved tahini mixture over the ganache (imagine a grid, and add one dollop of tahini mixture to each square on that grid). With the tip of a butter or pairing knife, swirl the tahini dollops into the ganache.
Allow 5-10 minute for the tahini swirl to set before cutting in!
