Bring eggs, butter, and milk to room temperature before mixing to ensure even blending and a lighter, more uniform crumb structure in your finished cake.

Mix dry ingredients separately, then fold them gently into wet ingredients just until combined—overmixing activates gluten and creates a dense, tough cake instead of the tender result you want.

Sift flour and baking powder together before adding to the batter to remove lumps, aerate the mixture, and guarantee an even rise throughout your cake.

Preheat your oven for 15 minutes and place the cake rack in the center position to ensure consistent, even baking without browning too quickly on the edges.

Let the cake cool completely to room temperature before dusting with powdered sugar, otherwise it will melt and create a sticky glaze rather than a beautiful, pristine coating.
