Bake the brownies for 33-36 minutes. Allow to cool completely in the pan before frosting.
Place the chocolate and tahini over a small saucepan with simmering water. Stir often until the chocolate is fully melted. Gently stir in the sifted powdered sugar a little at a time. Allow the frosting to sit for about 10 minutes to thicken.
Make the frosting
Frost the cooled brownies and sprinkle with sesame seeds, as desired. Cut into 16 squares and enjoy!
