FAQs

How do I prevent my mug cake from becoming rubbery?

Avoid overcooking the mug cake. Start with 1 minute on high power, then check if the top is just set. Overheating can dry out the batter and lead to a rubbery texture.

Can I make a mug cake without eggs?

Yes, mug cakes work perfectly without eggs. The combination of baking powder, milk, and oil helps the batter rise and stay moist even without eggs.

What size mug should I use for a microwave mug cake?

Use a microwave-safe mug that holds at least 8 to 12 ounces. This allows enough space for the cake to rise without overflowing during cooking.

Why did my mug cake overflow in the microwave?

Overflow usually happens when the mug is too small or the batter is overfilled. Make sure to fill the mug only halfway and use one that’s 8 oz or larger.
