Reasons This Treat Always Works
I've thrown this together countless times without fail. The milk brings tenderness, oil keeps everything moist, and those hints of vanilla and cinnamon create that classic coffee cake taste everybody goes nuts for.
Wonderfully Fluffy Results
You'll love how airy and soft it turns out. The brown sugar adds this lovely caramelish flavor, and every bite has just the right amount of spice. It's basically traditional coffee cake but ready in a flash.
Customize As You Please
I'll toss in chocolate chips sometimes. Other days I'll stir in a blob of peanut butter. That's what makes this so fun - you can twist it to match whatever you're in the mood for.
Tasty Companions
This goes down so well with your first coffee of the day or alongside afternoon tea. Wanna make it extra indulgent? Drop some vanilla ice cream on top while it's still warm - total bliss in a cup.

Quick Tidy Up
Another thing I love about this is how little washing up you'll face. Just one mug and a spoon to clean. Give them a quick rinse right after eating and you're done in moments.
Still Good Later
Even though it tastes best straight from the microwave, you can save it for later too. Just pop a cover on if you need to walk away - it'll stay nice and moist for several hours.
Fun For The Family
My children enjoy making these almost as much as eating them. It's a fantastic way to get kids excited about kitchen skills. We jazz them up with different toppings and colorful sprinkles.
Fits Any Moment
From quick morning treats to midnight snacks, this works whenever. It's casual enough for your own cravings but can be fancied up when friends stop by too.

Adjustable Sweetness
If sugar's a concern, just dial it back a bit. The brown sugar and cinnamon still pack plenty of flavor even when you use less of the sweet stuff.
Adapts To Your Needs
Want dairy free? Swap in some oat milk. Need gluten free? Your favorite GF flour mix usually works great. This little treat bends to fit almost any dietary requirement.
Finding Your Perfect Cook Time
Since microwaves vary, you might need to tweak the timing. Try 45 seconds first, then add more if needed. You'll soon figure out exactly how long works best in your kitchen.
Fancy It Up
When I want something more special, I'll add a swirl of caramel sauce or some fluffy whipped cream. Sometimes just sprinkling powdered sugar makes it look way more impressive.

Tasty Little Tweaks
Try grating in some orange zest or adding a dash of nutmeg. These small touches can transform your mug cake completely. I'm always playing around with different spice mixes.
Just Right Serving
That's the beauty of this treat - it's exactly one portion. No extra slices calling your name from the fridge - perfect for when you just want a tiny bit of something sweet.
Storing Any Leftovers
If you can't finish it all, just cover your mug and keep it for later. A quick 10-second zap brings back that fresh-baked feeling.
Your Go-To Mug Dessert
This tiny cake has become my go-to quick sweet fix. It's basic, satisfying and works with so many variations. After your first try, I bet you'll find yourself reaching for this again and again, just like I do.

Frequently Asked Questions
- → Can I swap the milk type?
Definitely! Use regular, almond, or even oat milk. Any liquid choice can work here.
- → Why yogurt instead of oil?
Greek yogurt lowers the fat while keeping the texture soft. You can still use oil if you'd prefer.
- → How to adjust microwave times?
Begin with 45 seconds for an 1100-watt microwave. If it's weaker, just add 15-second intervals until it's done.
- → Can I double this?
This is meant for one portion. Doubling might make the texture tricky, so sticking to one serving works best.
- → Why add cooking spray?
It keeps the cake from sticking, so cleanup is a breeze. It also helps you remove the cake easily from the mug.
