- 1 cup (200g) granulated sugar
- 1½ teaspoons baking powder
- ½ teaspoon salt
- ½ cup unsalted butter, melted and slightly cooled
- ½ cup milk or buttermilk
- 1 large egg
- 2 teaspoons pure vanilla extract
For the Buttermilk Sauce

The baking soda reacts with the buttermilk to create a silky, caramel-like glaze that soaks beautifully into the cake.
Pro Tips for the Best Butter Cake
- Use room-temperature milk and eggs for smoother batter
- Do not overmix the batter or the cake can become dense
- Pour the sauce over the cake immediately after baking for maximum moisture
- Use real butter and pure vanilla extract for the richest flavor
- Let the cake rest before slicing so the glaze fully absorbs
