In a bowl, combine flour and cold, cubed butter.

Rub the butter into the flour until it resembles bread crumbs.

Add grated Parmesan cheese and red chilli flakes to the mixture.

Mix until the dough comes together into a ball.

Roll the dough into a log shape (or two smaller logs).

Wrap the dough log(s) in cling film and chill in the refrigerator for at least one hour, or until firm.

Preheat oven to 180°C (350°F).

Cut the chilled dough log into rounds approximately 1/3 inch thick.

Place the biscuit rounds on a baking sheet, leaving some space between each biscuit.

Place the baking sheet in the freezer for 10 minutes.

Bake in the preheated oven for 12-15 minutes, or until golden brown.

Serve the Parmesan Cheese Biscuits warm with tea.
