Tips for a Perfect Vanilla Mug Cake Every Time 

Use a large mug to prevent any overflowing cake in your microwave. This will prevent a big, sticky mess! 

Microwave wattages and power vary depending on what type of microwave you have and how old it may be. Be sure to keep an eye on your cake while it is in the microwave so it doesn’t overcook. 

Worried about your cake overcooking? Set your timer for 45 seconds and then check. If your cake hasn’t pulled away from the edges of the mug, it’s not finished. Pop it back in the microwave for an additional 15 seconds.

Faqs

How long to microwave a mug cake? 

After lots of trial and error, we have come to understand the very best way to know if your cook is done is if it has pulled away from the sides of the mug. When you back a cake in the oven you look for a spring back from the top of your cake, so use the same method here while also looking for the pull. 

Why did my cake explode?  

It is very unlikely that your cake will explode in the microwave. However, there is really only one cause; a mug way too small. Your mug should be large enough to hold the cake batter as well as have at least 2 inches to expand. 

Can I add salt to make batter? 

We are big salt lovers at Steamy Kitchen, so YES! We suggest adding an 1/8th of a teaspoon of salt to your batter or sprinkle a little on top of your batter if you like a big salty punch of flavor at once.
