2 cups all-purpose flour, plus more for hands and work surface
2 tsp baking powder
1/2 tsp baking soda
1 tsp sugar
3/4 tsp salt
1/2 cup unsalted butter, very cold or frozen
1 cup cheddar cheese, shredded
1 stalk green onion, thinly sliced
1/2 tsp thyme
1/2 tsp garlic powder
1/2 cup buttermilk
1/4 cup whipping cream
2-3 tbsp water
1. Preheat oven to 400F. Line a baking sheet with parchment paper.
2. In a large bowl, whisk the flour, baking powder, baking soda, sugar, and salt together.
3. Grate the frozen butter into the flour mixture. With your fingers, crumble the butter into the flour until the mixture resembles coarse meal.
4. Add cheese, green onion, thyme, and garlic powder. Stir to combine.
5. Add in wet ingredients and mix until a shaggy dough is formed.
6. Pour the dough onto a floured surface and gently pat the dough until the flour mixture just comes together into one mass and shape the dough into a large rectangle. Be careful not to over mix.
7. Using a floured rolling pin, roll out the dough into a large rectangle. Fold it in half then roll out the dough again.
8. Using a sharp knife, cut the dough into 8 even rectangle biscuits, then cut in half to make triangles.
9. Place scones 1/2-inch apart on the prepared baking sheet.
8. Bake for 17 to 18 minutes, or until lightly golden and cooked through.
