This is a twist on the classic Millionaire bars - layered shortbread crust, caramel, and chocolate - with the addition of sesame throughout. There’s toasted sesame seeds mixed into our 3-2-1 shortbread crust, and sesame seeds sprinkled atop the dark chocolate top. But being the little tricksters that we are, we snuck a generous helping of tahini into the caramel layer, for that oh-so-very sesame goodness. These bars are super rich and luxurious - a little bit goes a long way!
