Coffee Mug Cake
This Coffee Mug Cake is a quick and easy treat when you’re craving something sweet! I was supposed to be making you a Mocha Chiffon Cake for today, but when I got ready to make it I realized I only had 3 eggs and I needed 6. So I decided to cut the recipe in half… well sometimes we make decisions and don’t act on them fully. You know, like halving the eggs but completely forgetting to halve the rest of the recipe until it’s all mixed together and you have that “oh crap” moment.Pin this Coffee Mug Cake for Later!

I have never made a mug cake but I am definitely going to try this. It looks fantastic, plus quick and easy. You’re right, during the busy rush of the holidays sometimes just making simple treats are perfect so we can focus on the important stuff. #client
Exactly! We get so caught up in try to impress our guests and our families that we forget to just enjoy the little comforts and moments happening around us!
I’m always amazed at what the microwave can do, — love the video, and gotta love Starbucks 😉
Thanks so much, Sue! I don’t use the microwave often, but when I do, I make it worth my while 😉
