Peanut Butter Mug Cake

Good afternoon guys! I hope your weekends have been as fun as mine has been so far. I have lots of studying to do, but I think I’m doing an okay job with balancing it all out. This week is midterm week for me, so I have exams in virtually all of my classes. After my first orchestra concert of the year on Saturday night, things will get much easier for me, until finals, that is!

I’ll be the first one to admit that I was a little bit wary of microwave cakes that take less than 7 minutes to make. Especially since at home I was fortunate enough to have access to high end kitchen equipment, I never bothered trying any of the mug cakes or other assorted microwaveable recipes. Clearly, that all changed once I got to college, where the most amount of cooking I could do was make ramen in my room, using the hot water from my coffee maker. Honestly, I can’t say I’m completely converted to the world of mug cakes, but for a lazy college student with no access to a kitchen, it’s great way to treat yourself.

I figured I would start out with a pretty simple flavor- peanut butter. The ingredients are similar to those of a normal cake, just scaled down greatly. I don’t have measuring cups in my room, so I did just eyeball most of the ingredients (I would probably use measuring cups if I had them, however). Now that I’ve broken my mug cake virginity, I can’t wait to try some other flavors and even branch out into savory microwaveable treats!

(Also- if anyone has photography tips for a poorly lit dorm room, please send them my way!)

    As a university student myself, I have to say that mug cakes are one of the best desserts ever! Recently I made one with spelt flour, cocoa powder, and coconut oil to make a decadent chocolate version and topped it with PB. Heavenly! 🙂
    BTW, I just discovered your blog and absolutely love it. Thank you for sharing such awesome recipes – I can’t wait to try them out!
