Preheat oven to 350 °F and line a baking tray with parchment paper.
Beat butter, honey and brown sugar until fluffy. Beat in egg and vanilla. In a separate bowl, combine flour, baking powder, salt and cinnamon and add to butter mixture. Stir in toasted sesame seeds. Drop by teaspoonfuls onto prepared baking tray, leaving 2 inches between each cookie. Bake for about 7 minutes, until cookies brown around the edges. Cool cookies for 1 minute, then remove to cool completely.
