Preheat the oven to 180°C Fan. Mix plain flour with baking powder and chilli powder.
Cube your room temperature butter and rub into the flour mixture with your fingertips, until the mixture resembles breadcrumbs.
Grate the cheese and set some aside for sprinkling on top of your scones. Mix the rest in with the flour mixture.
Add milk (start by adding 40ml and add extra if you need) and bring it into a cohesive ball (ingredients need to come together but you don't want the dough sticky).
Flatten it to a thick circle (2.5cm thick) and cut out 4-5 scones using a cutter (we used a 6 cm cutter). Place them on a lined baking sheet.
Glaze the tops of your cheese scones with some milk and sprinkle the saved cheddar.
Bake in the middle of the oven for 12-15 minutes until risen and golden brown. Leave to cool for 5 minutes and serve warm.
Notes
These scones aren't spicy, but skip the chilli powder if you don't like any chilli heat in your food.
