Preheat oven to 350 degrees F. Line a baking sheet with parchment paper.
In a large bowl, mix flour, baking powder, salt, sugar, and cayenne together using a whisk. Add the herbs, cheese and buttermilk. Stir together until dough forms. Once dough has formed, using an ice cream scooper, scoop out dough onto baking tray. With a brush, lightly butter tops. Bake for 15 minutes.
