Preheat oven to 375°F (190°C). Grease 8 ramekins or a 12-count muffin tray with butter or oil; set aside. In a large bowl, whisk flour, sugar, salt, and baking powder. Make a well in the center. Add melted butter (or oil), egg, milk, and vanilla extract. Whisk until combined and smooth. Divide batter evenly into prepared ramekins or muffin tray, filling about 3/4 full. Bake for 15-20 minutes or until golden and set. A toothpick inserted into the side of cakes should come out clean. Allow cakes to cool for 5 minutes, then loosen edges and remove carefully.
