Cut the butter into small cubes and store in the fridge until ready to use.
Into a large mixing bowl, add the self rising flour and the cold butter. Using a pastry cutter, cut the butter into the flour until the butter is about the size of peas.
Pour the buttermilk into the mixture and mix with a spoon or a spatula until just combined.
Turn out the dough onto a lightly floured surface and gently knead it a few times until it comes together.
Flatten it into a rectangle, then fold it over itself like an envelope. Repeat this process two to three times for extra flakiness.
Using a rolling pin, roll out your dough to about ¾-inch thickness and use a biscuit cutter or glass to cut out rounds from the dough without twisting—this helps them rise evenly during baking.
Place your biscuit rounds onto a parchment paper-lined baking pan close together for soft sides or spaced apart for crispier edges. Brush the top with milk or buttermilk.
Bake in a 220c (430f) preheated oven for 10-12 minutes until golden brown on top.
Once baked, remove from oven and allow them to cool slightly on a wire rack before serving warm with your favorite spreads like honey or jam.
Notes
Use cold butter. Ensure your butter is cold before incorporating it into the flour. Cold butter creates steam during baking, which results in flaky layers.
Measure yourflour correctly! When measuring your flour, avoid scooping it with a measuring cup. Instead, stir the flour with a spoon to create as many air pockets as possible, and spoon it into your measuring cup. Finally, level it with a back of a knife.
Don't overmix. Mix the ingredients until they are just combined. Overworking the dough can lead to tough biscuits instead of light and fluffy ones.
Chill your ingredients. Besides cold butter, keep your buttermilk chilled as well. This helps maintain the dough's consistency and prevents it from becoming sticky.
Flour your surface lightly. When rolling out or shaping your dough, use a light dusting of self-rising flour to prevent sticking without altering the dough's composition too much.
Pat don't roll. Patting down the dough gently with your hands instead of using a rolling pin can help retain air pockets that contribute to fluffiness.
Keep the dough thick. Aim for a thickness of about ¾ inch when shaping your biscuits. This ensures they rise nicely in the oven.
Use a sharp cutter. Use a sharp biscuit cutter or knife for clean edges, which helps them rise evenly without sealing off layers.
Avoid twisting cutter. Press down firmly with your cutter but avoid twisting as this can seal edges and prevent rising.
Space them apart or together strategically. For crispier sides, space each biscuit apart on the baking sheet; for softer sides, place them close together so they touch during baking.
