Ingredients

• ½ cup unsalted butter, room temperature
• ½ cup tahini
• 1 c sugar
• 1 large egg
• 1 egg yolk
• 1 tsp vanilla
• 1 cup + 2 tb flour
• ½ tsp baking soda
• ½ tsp baking powder
• 1 tsp kosher salt
• 1¾ cup valrhona discs (64% cocoa)
• maldon salt

Instructions

1. In the bowl of an electric mixer fitted with a paddle attachment, cream the butter, tahini, and sugar together on medium speed until light and fluffy, about 5 minutes. add the egg, egg yolk, and vanilla and continue mixing on medium for another 5 minutes. sift the flour, baking soda, baking powder, and salt into a large bowl and combine. add the flour mixture to the butter mixture and mix on low until just combined. add the chocolate discs and mix them in by hand with a rubber spatula.
2. Line a baking sheet with parchment paper. using a 2-ounce ice cream scoop, scoop out 12 dough balls and place them on the baking sheet. wrap the baking sheet with plastic wrap and place it in the freezer for no less than 12 hours. this will allow the gluten in the flour to relax and will give you a tender soft cookie. do not skip this step.
3. At this point you can bake 1 or bake 12. keep the cookie dough balls in zip-top bags in the freezer for up to 6 months.
4. Preheat the oven to 325ºf and line a baking sheet with parchment or a silicone mat. space the cookie dough balls at least 3” apart to allow for them to spread. bake for 13-16 minutes until just golden brown around the edges. they will still look fairly unbaked in the middle, which is perfect. sprinkle each with maldon salt when they come out o the oven. allow to cool for 20 minutes on the baking sheet or cooling rack.
