01 - In a saucepan over low heat, melt the butter with the milk, sugar, and a pinch of salt. Stir continuously until the butter is completely melted. Remove from heat and let the mixture 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 mixture into the flour mixture. Stir with a wooden spoon until the ingredients begin to come together, then knead by hand until you achieve a smooth, homogeneous dough.
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. Line a baking sheet with parchment paper.
06 - On a lightly floured work surface, roll out the dough to approximately 1/8 inch (5 mm) thickness. Cut out biscuits using a classic Petit Beurre cutter or a sharp knife.
07 - Transfer the cut biscuits onto the prepared baking sheet. Prick each biscuit several times with a fork for the traditional decorative pattern.
08 - Bake for 12 minutes, or until the edges are lightly golden brown. Keep a close eye on them during the final minutes to prevent overbaking.
09 - Transfer the biscuits to a wire cooling rack and let them cool completely before serving. This ensures they develop their signature crisp texture.
