• Preheat the oven to 170°C (340°F). Grease two 7-inch cake pans with butter or oil and line them with parchment paper.
• In a mixing bowl, combine, self-raising flour, cocoa powder, baking powder, mix well and set aside.
• Next, in a separate bowl, beat the butter for one minute or until creamy then add the caster sugar and whisk for about 5 minutes or until light and fluffy.
• Crack an egg into the mixture and mix until fully incorporated. Repeat with the remaining eggs.
• Then add half of the dry ingredients to the wet mixture, folding gently. Next, pour in half of the milk to achieve a smoother batter and add the remaining dry ingredients and mix until just incorporated.
• Evenly distribute the batter between the prepared pans and bake for 30-35 minutes or until a skewer comes out clean.
• Once the cake is done, gently place it upside down on a cooling rack and let it cool for 2 hours or completely before decorating.
