Preheat your oven to 400°F (200°C) and prepare a baking sheet with parchment paper.

In a large mixing bowl, combine 2 cups of all-purpose flour, 1 tablespoon of baking powder, and 1 teaspoon of kosher salt.

Cut 1/2 cup of cold, unsalted butter into small cubes and add it to the flour mixture, working until it resembles coarse crumbs.

Fold in 1 cup of shredded cheddar cheese and 1/4 cup of chopped green onions.

In a separate bowl, whisk together 1/2 cup of plain Greek yogurt and approximately 1/4 cup of water until smooth.

Pour the wet ingredients into the dry mixture and gently mix to form a shaggy dough.

Transfer the dough onto a floured surface and knead gently for about 30 seconds.

Pat the dough into a 1-inch thick circle and cut into 6 large or 8 medium wedges.

Brush the tops with cream or milk before baking for about 17 to 20 minutes.

Let the scones cool for a few minutes on a wire rack before serving.
