Preheat the oven to 220°C (200°C fan) / 425°F. Line two baking sheets with parchment paper. This ensures the scones bake evenly and do not stick.

In a large mixing bowl, combine self-raising flour, baking powder, and salt. Stir well to distribute ingredients evenly. This creates a light base for the scones.

Add cubed butter to the flour mixture. Rub it in using your fingertips until it resembles fine breadcrumbs. This step gives the scones a light, flaky texture.

Stir in the grated cheddar cheese. Mix gently to ensure the cheese is evenly spread. The cheese adds flavor and richness to the scones.

Gradually add milk to the dry mixture. Mix with a wooden spoon until it forms a soft dough. Do not overwork the dough, or the scones may become tough.

Turn the dough onto a floured surface. Roll it out to about 2cm thick. Use a round cutter or knife to shape the scones. Place them on the prepared baking sheets, leaving space to rise.

Brush the tops lightly with milk or beaten egg for a golden finish. This step gives scones a beautiful shiny top and helps them brown evenly.

Bake in the preheated oven for 12–15 minutes. They should rise and turn golden brown. Remove from the oven and transfer to a cooling rack. Serve warm for the best flavor.
