Prepare the Oven and Pan: Start by heating the oven to 170°C. Grease a loaf pan well and line it with baking paper. This helps the cake rise evenly and release cleanly after baking.
Cream Butter and Sugar: Add the softened butter and caster sugar to a bowl. Beat until pale and fluffy. This step adds air and sets the texture for the cake.
Add the Eggs Slowly: Crack in one egg at a time and beat well after each addition. This keeps the batter smooth and prevents splitting.
Mix in Vanilla: Pour in the vanilla extract and mix gently. The scent alone starts to hint at how comforting this cake will taste.
Combine Dry Ingredients: In another bowl, whisk cake flour, baking powder, and salt. This spreads the leavening evenly through the flour.
Finish the Batter: Add the dry mixture to the batter in parts, alternating with the milk. Mix gently until smooth and thick with no dry spots.
Bake the Cake: Transfer the batter to the prepared pan and smooth the top. Bake for 45 to 55 minutes until golden and a skewer comes out clean. Let it cool before slicing.
