FAQs

Can I use a different type of flour?

All-purpose flour works best for this recipe to achieve a soft and fluffy texture. Using whole wheat or gluten-free flour may change the cake’s consistency and cooking time.

How do I know when the cake is done in the microwave?

The cake should rise and look set on top but still slightly moist. Be careful not to overcook, as the cake can become dry and rubbery. Start checking at 60 seconds and adjust time as needed based on your microwave’s power.
