💭Recipe Tips:
- Cook Time Varies - Microwaves have different strengths which will impact the cook time. I recommend you check after 40 seconds then add more time, as needed. If you make it in a more shallow dish vs the mug, then it will also cook faster.
- Mug Size - Use a standard size (8oz or larger) microwave safe mug. If you don't have a mug, you can use another microwave-safe dish to cook it - such as a large ramekin.
👩🍳Recipe FAQs:
This recipe is written for one cake in a mug, but you can easily double it to make two! You can mix them up separately in two mugs or mix up the batter before adding cinnamon sugar, divide between two mugs, and then add the cinnamon sugar to both. It’s best to microwave them separately, though.
Any standard size coffee mug works! I used mugs that were at least 8 ounces to leave room for the cake to puff up and rise while ‘baking’. The most important piece is to use a mug that is microwave safe!
Because you eat the coffee cake right out of the mug, you do not need to grease. Although, if you want easier clean up you could spray with cooking spray before cooking. I do not grease and instead just soak the mug in some warm soapy water for a few minutes before cleaning to remove any cooked on cake.
If you overcook a mug cake, then it can get a hard and tough texture vs being light and moist. The key is to watch and check the mug cake closely. I like to check at 40 seconds and then microwave in 5 second intervals until done. Better to undercook by 5 seconds than overcook by 5 seconds!
