Instructions

Preheat your oven to 350°F (177°C) and grease and line two 8-inch round cake tins with parchment paper.
In a stand mixer with a paddle attachment, cream the softened butter and golden caster sugar on medium-high speed for exactly 3 minutes until the mixture is pale and voluminous.
Add the eggs one at a time, beating for 30 seconds after each addition; if the mixture starts to curdle, add one tablespoon of the measured flour.
Stir in the vanilla extract, then sift in the self-raising flour, cocoa powder, and baking powder.
Mix on the lowest speed while adding the milk, stopping the moment no streaks of dry flour remain to avoid over-mixing.
Divide the batter equally between the prepared tins and bake for 25 to 30 minutes until the centers spring back when pressed or a skewer emerges clean.
Cool in the tins for 10 minutes before transferring to a wire rack to cool completely before decorating.

Notes

For the most precise results, use a digital scale to weigh your ingredients and an independent oven thermometer to verify your heat. If you plan on carving the cake or applying intricate designs, chilling the layers in the refrigerator for at least two hours after they have cooled will help set the crumb and minimize tearing.
