• To achieve cake perfection, start by preheating your oven to a toasty 350 degrees.
• Take your round cake pans and give them a little love by greasing them with butter or cooking spray. Line them with parchment paper for extra ease.
• In a spacious mixing bowl, whip up the cake batter magic. Combine the flour and baking soda, giving it a gentle mix. Sprinkle a pinch of salt, then sprinkle the baking powder.
• In a separate bowl, blend the butter until it transforms into a creamy delight. Add oil and gracefully incorporate the cocoa powder. Sprinkle in all sorts of sugar and join forces with the butter, blending at high speed.
• Crack the eggs into the same bowl and beat them with finesse. Add a touch of vanilla extract to elevate the flavour.
• Slowly unite all three mixtures in a grand gesture, stirring gently. To add an extra kick, pour in some hot coffee and blend until the texture is creamy, smooth, and harmoniously combined.
• Transfer your prepared batter to the awaiting baking pan, allowing it to embrace the oven's warmth.
• Place the pans gently in the oven, letting them bask in the heat for a minimum of 45 minutes. Keep a watchful eye, and once baked to perfection, remove them from the oven with care.
