01 - In a saucepan, combine the butter, milk, sugar, and a pinch of salt. Heat over low heat, stirring until the butter is completely melted. Let the mixture cool slightly.
02 - In a large mixing bowl, whisk together the flour and baking powder until evenly distributed.
03 - Pour the warm butter mixture into the flour. Stir with a wooden spoon, then knead by hand until a smooth, homogeneous dough forms.
04 - Shape the dough into a ball, wrap tightly in plastic wrap, and refrigerate for 30 minutes to firm up.
05 - Preheat the oven to 350°F on conventional bake setting.
06 - On a lightly floured surface, roll out the dough to about 1/5 inch thickness. Cut out biscuits using a traditional Petit Beurre cutter or a sharp knife.
07 - Transfer the cut biscuits onto a baking sheet lined with parchment paper. Prick each biscuit decoratively with a fork.
08 - Bake for 12 minutes, or until the edges are lightly golden brown.
09 - Let the biscuits cool on a wire rack before serving. This ensures they crisp up properly.
