Preheat oven to 450 degrees. Spray a baking sheet and set aside.
In a large bowl whisk together barley flour, all-purpose flour, sugar, baking powder, and salt.
Cut in butter and combine until mixture resembles coarse crumbles.
Add in milk, egg, and vanilla. Mix until well combined and shape dough into a ball. Cut dough into 6 even pieces.
Place evenly on the baking sheet and place in oven. Bake for 12-15 minutes or until golden brown. Remove from oven and top with toppings of your choice. Serve immediately and enjoy!
