A wonderfully moist and intensely chocolatey cake topped with a rich, buttery milk chocolate ganache, perfect for any occasion.
Ensure the coffee and cocoa mixture is completely cool before adding the egg to prevent scrambling.
Do not overmix the cake batter once the flour is added; mix until just combined for a tender crumb.
Allow the ganache to cool and thicken fully before attempting to frost the cake.
This cake is best enjoyed at room temperature; if refrigerated, let it sit out for 30-60 minutes before serving.
