Gather all your ingredients and preheat your oven to 400°F (200°C).

In a mixing bowl, combine the flour, baking powder, and salt, then cut in the cold butter until the mixture resembles coarse crumbs.

Fold in the grated Irish cheddar cheese and chopped chives until just combined.

Add milk to the mixture and stir until a sticky dough forms. On a floured surface, pat it to 1-inch thickness and cut out circles.

Sprinkle additional cheese and chives on top of each biscuit before baking.

Bake for 15-20 minutes until puffed and golden brown. Cool for 5 minutes before serving.
