Soft chocolate sesame butter cookies are sandwiched around a sweet and decadent chocolate sesame buttercream filling, and dipped in dark chocolate. Indulge your deep chocolate craving with these rich and nutty cookies. (Great for those with nut allergies!)
Place the butter, chocolate sesame butter, and brown sugar in a large mixing bowl, and mix on low speed until smooth.
Add the flour, cornstarch, cocoa, and salt, and mix until the dough pulls away from the sides of the bowl.
Place some of the dough between 2 sheets of parchment paper, and roll to a thickness of ¼ inch (I use rolling pin rings to achieve a uniform thickness).
Cut cookies out with a 2-inch fluted circle cookie cutter, and transfer to a parchment-lined baking sheet.
Combine the butter and chocolate sesame butter in a large mixing bowl and mix until smooth.
Add the powdered sugar and vanilla, and beat until completely incorporated.
Melt the dark chocolate melting wafers according to the directions on the package, and dip half the cookie. Set on a parchment-lined baking sheet, and sprinkle with a pinch of sesame seeds. Cool completely.
