Preheat oven to 450ºF. Spread the sesame seeds on a baking sheet and toast in the oven for about 10 to 12 minutes. Remove and cool.
Heat the honey and butter in a small saucepan over medium-low heat, stirring until it bubbles and darkens somewhat, about 3 to 5 minutes.
Stir the toasted sesame seeds into honey mixture. Spread the mass onto a buttered baking sheet to a thickness of about 1/4 inch. Cool until it is just warm and cut into finger-sized pieces. Cool completely and serve.
(For a tasty coating that will keep fingers less sticky, roll the candy in more toasted sesame seeds to coat after cutting it into pieces.).
