Line a large baking tray with a baking paper/parchment paper. Set aside.
Sieve flour into a medium mixing bowl and mix it with baking powder. Set aside.
Rub butter into the flour mixture until it resembles breadcrumbs.
Put this mixture in the freezer for about 30 minutes, so that the butter gets cold.
After 30 minutes, take the butterflour mixture out of the fridge,
Add grated cheese into the flour mixture, stir to combine.
Create a well in the centre, whisk buttermilk, sugar, egg yolk, egg and vanilla extract in a mixing jug.
Pour the wet ingredients into the flourbutter mixture, mix with a fork until there’s no remaining dry ingredients on the bowl.
Transfer the dough into a floured surface and gently knead until it comes together, adding flour whenever necessary.
Using a rolling pin, roll it out into a rectangular shape. Fold the dough into thirds, like you would an A4 paper.
Repeat the above step 2 more times. Total folds will be 3.
After the 3rd roll, roll it to make it 1 ½ to 2 cm high and use a 2cm cookie cutter to cut the dough, keep kneading and levelling it until all is cut into circles.
Transfer the scone cut dough unto a baking tray lined with a baking paper, then refrigerate for 30 minutes.
Take out the tray and brush the scones dough with an egg wash, then bake into the prepared oven for 15 minutes.
Serve with butter, cheese and jam.
