01 - In a saucepan over low heat, combine the butter, whole milk, sugar, and a pinch of salt. Stir continuously until the butter is completely melted and the mixture is smooth. Remove from heat and let 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. Stir with a wooden spoon until the ingredients 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 your oven to 350°F using conventional bake setting. Line a baking sheet with parchment paper.
06 - On a lightly floured work surface, roll the dough out to approximately ⅕ inch 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 to create the traditional decorative pattern and prevent puffing.
08 - Bake for 12 minutes, or until the edges are lightly golden brown. Keep a close eye on them during the last few minutes to avoid overbaking.
09 - Transfer the biscuits to a wire cooling rack and let them cool completely before serving. They will crisp up as they cool.
