preheat oven to 350F

combine flour, cocoa powder, sugar and salt in a bowl; stir in melted butter and combine. press into a 9" tart pan, evenly across the bottom and up the sides.

bake for 15-20 minutes until firm. remove from oven and let cool completely.

in a bowl off to the side, combine white chocolate chips, tahini and salt. in a sauce pan, heat the cream and honey - whisk to combine and only warm up till it's simmering, not boiling. pour the cream/honey over the white chocolate/tahini/salt and combine. whisk to combine and make sure it's smooth and glossy.

pour the filling into the cooled tart and smooth on top.

microwave the dark chocolate chips with a splash of cream to help loosen them, until liquidy. using a teaspoon, drizzle dark chocolate over the white chocolate tart and then artifully use a knife or chop stick to make the marble-y design.

plop into the fridge and cool for at least an hour.

hit it with flaky salt before serving!
