Preheat your oven to 350°F (175°C). Line your cake pan with parchment paper and lightly grease the sides. This step helps the cake release easily after baking.

Place softened butter and sugar in a mixing bowl. Beat them together using a mixer until light and fluffy. This step creates a smooth base and adds air to the batter.

Crack the eggs into the mixture one at a time. Beat well after each egg. This helps the batter stay smooth and prevents it from separating.

In another bowl, combine flour, baking powder and salt. Stir them gently with a spoon. Mixing dry ingredients first helps them spread evenly in the cake batter.

Add the dry mixture slowly to the butter mixture. Pour in milk and vanilla extract. Mix gently until the batter becomes smooth and creamy.

Pour the batter into the prepared cake pan. Spread it evenly using a spatula. Smooth the top so the cake bakes evenly.

Place the pan in the oven and bake for 30–35 minutes. The top should turn golden and a toothpick inserted in the center should come out clean.

Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer it to a cooling rack to cool completely.

Dust powdered sugar lightly over the top for a classic finish. This simple decoration makes the cake look elegant.

Cut the cake into slices and serve with tea or coffee. The soft texture and buttery flavor make every bite delicious.
