First things first, round up all your ingredients. It’s always smoother when you’re not searching high and low mid-process.
Fire up that oven to a blazing 450 degrees F (or 230 degrees C for our metric-loving friends).
Take your trusty 8-inch square baking dish, glass or ceramic works best. Pop the butter in and give it a good melt in the microwave. Start with a minute, then check and stir. If it needs a tad more melting, go in 20-second spurts until it’s all liquid gold.
Grab a bowl and sift in your flour, baking powder, sugar, and salt. Give it a good whisk – we want all those ingredients mingling.
Now for the magic – pour in that buttermilk and stir until you have a lovely, cohesive mix.
Gently pour your biscuit mixture over that melted butter in the dish. To get those perfect portions, use a bench scraper (or a trusty old knife) and mark out 9 squares.
Into the oven they go! Keep a keen eye on them, and in about 20 to 25 minutes, they should be turning a lovely golden brown on top.
