FAQs

1. Can I use regular milk instead of coconut milk?

While you can substitute, the coconut milk is crucial for the characteristic flavor and texture of Bánh bò bông. Using regular milk will result in a less flavorful and potentially less fluffy cake.

2. Why is my cake not as fluffy as expected?

This is often due to not properly whipping the egg whites or using old baking powder. Ensure your egg whites are stiff peaks before gently folding them into the batter, and always check the expiry date of your baking powder.
