Mix dry ingredients in a bowl: whisk together all-purpose flour, baking powder, baking soda, and kosher salt.

Cream the butter and sugars together with an electric mixer until light and fluffy.

Add honey, egg, and vanilla extract, mixing until fully combined.

Gradually add dry ingredients to wet mixture until a smooth dough forms; fold in toasted sesame seeds.

Chill the dough covered in refrigerator for at least 2 hours or overnight.

Preheat oven to 350°F (175°C). Scoop dough, roll into balls, and optionally roll in more sesame seeds.

Bake for 10-12 minutes until edges are golden but centers remain soft.

Cool on the pan for 5 minutes before transferring to a wire rack.
