Preheat the oven to 350 degrees F (175 degrees C). Grease 2 baking sheets.

Whisk flour and baking powder together in a bowl; stir in raisins. Whisk milk and eggs together in a separate bowl.

Beat butter, sugar, and salt together in a bowl with an electric mixer until light and fluffy, about 1 minute. Beat in egg mixture, then stir in flour mixture until just combined.

Turn dough out onto a lightly floured surface and pat or roll out until 1-inch thick. Cut into 24 biscuits with a biscuit cutter or juice glass; place onto the prepared baking sheets.

Bake in the preheated oven until golden brown, about 10 minutes.
