Preheat your oven to 450°F (232°C). This high temperature is key to achieving that golden brown exterior!
In a large mixing bowl, combine the self-rising flour and grated cold butter. Use your fingers or a pastry cutter to mix until the mixture resembles coarse crumbs.
Pour in the buttermilk and gently stir until just combined. Be careful not to overmix; a few lumps are perfectly fine!
Turn the dough onto a lightly floured surface. Pat it down gently with your hands until it’s about 1-inch thick.
Using a cookie cutter, cut out rounds from the dough. Place the biscuits on a baking sheet lined with parchment paper, leaving a little space between each one.
Bake in the preheated oven for 12-15 minutes, or until the tops are golden brown and the biscuits have risen beautifully.
Remove the biscuits from the oven and let them cool for a few minutes. Serve warm with your favorite toppings, such as honey, butter, or gravy.
