This video is my family recipe for a soft and moist butter cake with a cinnamon twist. Here's the key summary: Family recipe: This cake is my family tradition, originally made with Malacca palm sugar. The video uses Muscovado sugar as a substitute. Key ingredients: Self-raising flour, butter, caster sugar, eggs, vanilla extract, and cinnamon. Bake at 160°C (320°F) for 25-30 minutes. Tips: The curdled batter after adding eggs is normal and will become smooth with mixing. Result: A moist butter cake with a beautiful marbled pattern from the cinnamon filling.
