Idk about you guys, but the weather here today is nasty. Like frigid cold, snowing and icy. Not that I’m complaining. Any reason to bundle up like a human burrito is one I’ll take advantage of. Here’s my one issue with the fun little blizzard we’ve got going on. I’m running out of baking materials and I really have no interest on putting on REAL pants to go to the store….yet I really, really want something sweet. So what’s a girl to bake?
Obviously a stupidly easy vanilla funfetti mug cake.

It’s perfect for those days where you want something delicious, sweet, and ready to eat in less than 5 minutes. Also, then you don’t have to worry about eating too much cake because it’s perfectly fine to eat this whole thing in one sitting.
(Not that I’d ever judge you for eating any sized cake in one sitting either).

Not to mention, if you’re trapped in a dorm room suffering through an all-night study sesh…girl, this mug cake is here for you. Trust me, I ate wayyyy too many of these things in college.
Useful Tools for a Funfetti Mug Cake
A Sassy-Ass Mug: Everyone needs a good mug that lets people know that despite the cake you’re not always sweet as sugar.
And of course, a funfetti cake isn’t a thing without some classic rainbow sprinkles. Get them here if you don’t hoard sprinkles like me.
Useful Tips for your Funfetti Mug Cake
Use Brown Sugar
Brown sugar makes the cake much moister and softer and less spongy than regular white sugar.
Allow your melted butter to cool some
Especially allow your melted butter to cool before you add your egg. Because hot butter and egg result in a weird semi cooked egg. Which, well, ew.
Any Milk Will Do
Cow’s milk, goat’s milk, oat milk, or coconut milk, they all work well.
I personally use coconut milk because that’s what I normally have on hand. Work with what you’ve got.
Watch Your Mug Cake While it Cooks
Sometimes if your favorite mug is slightly too small you risk an overflow in the microwave. So just keep an eye on your cake while it bakes to avoid disappointment.
If it’s about to overflow, open the microwave, let it deflate for a second and the continue cooking.
Doing this will definitely change how the cake turns out but at least you’ll have less mess to clean and will know for next time to use a larger mug.
How to make your funfetti mug cake

Reason 527 why mug cakes are awesome: they take less than 5 minutes start to finish. So yeah, that’s including cook time.
All you need to do is melt your butter, allow it to cool for a moment, and then mix everything into your favorite mug.
Please make sure it’s a microwavable mug because I cannot be held liable for you setting your microwave on fire or your favorite mug exploding….not that I’ve ever had experience setting my microwave on fire….
Once you’ve whisked everything together with a fork, microwave that bad boy for 1 minute and 45 seconds. At times (depending on the strength of the various microwaves I’ve used), it may need 2 minutes or a touch more.
The top of the cake should be set and not jiggly.
The top may still look wet but fear not. Let your cake sit for a couple minutes and that excess wetness will be no more.
Make yourself a little glaze
I’m super lazy and typically only add more sprinkles or some powdered sugar to the top but I suppose you could make a quick glaze to go on top.
To do that, take 3 tablespoon of powdered sugar + 1.5 tsp of your choice of milk, add the powdered sugar to a small bowl and then the milk and whisk the sh*t out of it until it’s smooth. Drizzle it on your hot funfetti milk cake and bask in the amazingness.
Super simple glaze but again, most of the time when I’m hankering for a mug cake I want to eat it yesterday so there’s no way I’m taking more time to add more steps. 😂
