In a large mixing bowl, beat butter until light and fluffy for 2–3 minutes. Add granulated sugar and continue beating for 5 minutes until pale and well combined.

Add eggs one at a time, mixing well after each addition to achieve a smooth batter.

Fold in vanilla extract thoroughly to ensure even distribution.

Let cakes cool in pans for 10 minutes, then turn out onto wire racks and cool completely before icing.

Combine sugar, butter, and evaporated milk in a heavy-bottomed saucepan. Bring to a boil over medium heat, stirring constantly. Once boiling, reduce to a gentle simmer and cook for 15–20 minutes, stirring frequently, until mixture thickens and deepens to a caramel shade. Remove from heat and stir in vanilla and salt. Beat with a wooden spoon until icing cools slightly and reaches spreading consistency.
