Weigh out butter whilst cubing it & leave to come to room temperature. Smaller cubes (about 1cm or ⅓" ) is good since a smaller surface area means they will soften faster). If you forget to take out on time, try a hack I reviewed for softening butter in about 12 minutes. Prepare a large baking tray/sheet with baking/parchment paper (grease in place if there is no lip to it).
Weigh/measure in the flour into a large bowl, spoon in the baking powder, give it a mix through & then add in the softened butter & give a quick mix through.
'Cut the butter' into the flour in a choice of 3 ways. Use your hands and rub some of the flour and butter between your finger tips, lifting and repeating, until you have smaller flour coated butter pieces, about breadcrumb size. You can also use 2 butter knives to do this. I prefer to use a pastry cutter/blender for this job. Push down into the bowl & do a squashing motion whilst turning the cutter left and right. Repeat this until all the butter is now in tiny pieces, coated by the flour. See video for reference.
Add in the sugar & give a good mix through for even distribution. Pre-heat the oven to 220°c/200°c Fan Oven/425°f/Gas Mark 6.
Beat the 2 eggs in a jug & top up to the 300ml/10 fl oz or 1 ¼ cup mark with the milk, (depending on the size of the eggs, you might not need as much milk). Whisk together & reserve 2 tbsp in a small bowl for later.
Gradually add the egg/milk mixture to the dry ingredients until a soft but slightly sticky dough is formed. I tend to use a large spoon to start to mix it in, and then move on to using my hands. DO NOT USE A FOOD PROCESSOR OR MIXER. Only add enough of the liquid until just sticky.
Lightly flour a pastry board, counter/worktop or use some baking/parchment paper with a little flour on top. Dip your cookie cutter in some flour.
Form the dough into a disc & then flatten gently with your hands until you have a level piece of dough about 1"/2½cm high. Try not to go smaller than this. Don’t be tempted to roll out the dough as this won’t help the scones to rise.
Push the floured cutter down and DO NOT TWIST the cutter. Twisting can ruin the end structure of the scones. Let it fall onto the prepared tray or leave to the end if it doesn’t come up with the cutter. At which point, just pull back the excess dough & transfer via a palette knife. Try not to touch the sides of the scone.
Gently roll up the scraps of dough by hand and flatten out to cut out more scones. Note that these last few scones, won’t be as perfect as the first ones, just because of more handling.
Brush very carefully the egg/milk liquid you reserved earlier, on to the tops of the scones only. If the liquid goes down the sides, it can ruin the rise of the scones. Shaking/taping the brush before moving to the scone & starting to brush from the centre and go outwards,
