In a large mixing bowl, whisk together the flour, baking powder, baking soda, and kosher salt until well combined.

In another bowl, cream together the butter, light brown sugar, and granulated sugar until fluffy, then mix in honey, egg, and vanilla extract.

Gradually mix the dry ingredients into the wet mixture until a smooth dough forms, then fold in toasted sesame seeds.

Cover the dough with plastic wrap and refrigerate for at least 2 hours.

Preheat the oven to 350°F (175°C). Roll portions of dough into balls and coat with sesame seeds before placing them on a baking sheet.

Bake for 10-12 minutes until the edges are golden; cool on the baking sheet for 5 minutes before transferring to a wire rack.
