01 - In a saucepan, gently melt the butter with the whole milk, granulated sugar, and a pinch of salt over low heat. Stir continuously until the butter is completely melted and the mixture is smooth. Remove from heat and allow to cool until lukewarm.
02 - In a large mixing bowl, whisk together the all-purpose flour and baking powder until evenly distributed.
03 - Pour the lukewarm butter and milk mixture into the flour mixture. Stir with a wooden spoon until the ingredients come together, then knead by hand until a smooth, homogeneous dough forms.
04 - Shape the dough into a ball, wrap it tightly in plastic wrap, and refrigerate for 30 minutes to firm up for easier rolling.
05 - Preheat the oven to 350°F (180°C) using conventional bake setting.
06 - On a lightly floured work surface, roll the chilled dough out to approximately 3/16 inch (5 mm) thickness. Cut out biscuits using a classic Petit Beurre cookie cutter or a sharp knife.
07 - Arrange the cut biscuits on a baking sheet lined with parchment paper. Prick each biscuit several times with a fork to create the traditional decorative pattern and to prevent puffing during baking.
08 - Bake on the center rack for 12 minutes, or until the edges are lightly golden brown.
09 - Transfer the biscuits to a wire cooling rack and allow them to cool completely before serving. Store in an airtight container at room temperature for up to one week.
