Dairy free Tahini brownies with tahini Ganache

0 First, preheat your oven to 350°F and line the sides and bottom of a 9x13-inch baking pan with parchment paper.
1 In a large mixing bowl, combine the baking soda and the unsweetened cocoa powder with a whisk. Add half of the tahini and coffee, then mix well. 
2 Next, add the sugars, eggs, and remaining tahini, and mix until smooth.
3 Incorporate the flour, vanilla extract, and salt, mixing until just combined. Be careful not to overmix. Gently fold in the chocolate chips.
4 Pour the brownie batter into your prepared pan, spreading it evenly. Bake for 33-38 minutes, or until a toothpick inserted in the center comes out with slightly wet crumbs. Let them cool completely over a wire rack while you make the ganache.
5 For the ganache, start by melting the chocolate (click here for tips on how to melt chocolate) and let it cool slightly in a small bowl. Then, add the tahini and mix well. Incorporate the powdered sugar, vanilla, and salt, mixing until smooth.
6 Pour the ganache over the cooled brownies and sprinkle with sesame seeds.
