Frequently Asked Questions
Should I use cooking spray in the mug?
The butter in this cranberry mug cake recipe works well enough to skip the cooking spray. The cake pulls away nicely from the mug.
What size mugs do you use?
The mugs pictured are 8 ounce tea cups. However, this is strictly because they look nice in pictures. You can use whatever size mug you have as long as it's microwave-safe.
Can I use frozen cranberries?
Yes, you can use frozen cranberries in this mug cake recipe. Frozen cranberries will create liquid as they cook in the microwave. No need to drain it, though, as it makes a tasty syrup to add to the top at the end.
What kind of low-carb milk to use?
I like unsweetened Milkadamia macadamia milk. You can use almond milk, coconut milk, or heavy cream, as well.
