Preheat your oven to 375°F (190°C). Grease a baking sheet or line it with parchment paper.
In a large bowl, whisk together the flour, baking powder, salt, and sugar.
Cut the softened butter into the dry ingredients using a pastry cutter or your fingers until the mixture resembles coarse crumbs.
In a separate bowl, whisk together the milk and egg.
Gradually add the wet ingredients to the dry ingredients, mixing until just combined. Do not overmix; the dough should be slightly sticky.
Turn the dough onto a floured surface and gently knead it a few times. Pat it out to about 1-inch thickness. Cut the dough into rounds using a biscuit cutter or a glass.
Place the dough rounds on the prepared baking sheet. Bake in the preheated oven for 15-20 minutes, or until the tops are golden brown.
Allow the bakes to cool slightly on a wire rack before serving.
Enjoy your meal!
