Step 1

Preheat your oven to 425 F degrees. Line a baking sheet with parchment paper.

Step 2

Whisk the buttermilk together with the cold egg in a small bowl. Set aside.

Step 3

In a large bowl add the flour, baking powder, salt and mix well.

Step 4

Using a pastry blender, cut in the butter until mixture resembles coarse meal. Mix in the cheddar cheese. Add the buttermilk mixture and using a wooden spoon mix everything together, then using your hands quickly knead a few times until the dough barely starts to come together.

Step 5

Turn the dough onto a floured surface and continue kneading a few times. Add more flour as needed, if the dough is too wet.

Step 6

Roll out the dough so that it's about half an inch thick to 3/4 of an inch.

Step 7

Using a round 2 inch cookie cutter or glass, cut into biscuits. Place the biscuits onto the prepared baking sheet. Gather the remaining dough and repeat making biscuits until you've used up all the dough. (I got 14 biscuits)

Step 8

Brush the biscuits with the beaten egg and bake in the preheated oven for about 20-25 minutes. Transfer to a rack to cool.
