Preheat oven to 450°F.

Step 2

Place butter in an 8-inch square glass or ceramic dish. Cover loosely and microwave in 30-second intervals until the butter melts.

Step 3

In a large bowl, whisk together the self-rising flour and sugar. Add the buttermilk to the flour mixture and stir just until combined.

Step 4

Transfer the dough to the dish with the melted butter. Gently press the dough into an even layer on top of the butter.

Step 5

Use a bench scraper or sharp knife to cut the dough into 9 squares.

Step 6

Bake for 20-25 minutes, until the tops of the biscuits are golden brown. Let the biscuits rest in the dish for at least 10 minutes, then serve.
