How to Make Your Chocolate Mug Cake
Start by Mixing the Dry Ingredients
Grab your favorite microwave-safe mug and throw in the all-purpose flour, dark cocoa powder, brown sugar, baking powder, and a dash of salt.
Stir them all together with a fork or spoon until everything is evenly combined. This step helps avoid any clumps and gives the cake a smooth texture once it’s baked.
Add the Wet Ingredients
Next, pour in the whole milk, canola oil, and vanilla extract. Now, give it a good mix again, making sure everything is well incorporated.
You should have a thick batter, don’t worry if it looks a little bit more dense than typical cake batter; that’s normal!
Stir in the Chocolate Chips
This is where the magic happens! Add your chocolate chips to the batter and give it a final stir.
These little guys will melt into gooey pockets of chocolate throughout the cake, so make sure they’re spread out evenly.
Pop It in the Microwave
Now comes the easy part! Place your mug in the microwave and heat it on high for about 60-90 seconds. Start checking at the 60-second mark.
You want the cake to rise and set in the middle.
Keep an eye on it because microwaves vary, and you don’t want to overcook it. It should look soft but firm enough to eat.
Let It Cool for a Minute
Once it’s done, take the mug out of the microwave (careful, it might be hot!) and let your cake cool for about a minute.
It’ll continue to cook a bit as it cools, which is why it’s important to give it that short break.
Dig In and Enjoy
Now comes the best part: grab a spoon and dive right in! You’ve just made a perfectly indulgent, warm chocolate mug cake in no time.

Pair it with some whipped cream, a scoop of ice cream, or even more chocolate chips if you’re feeling fancy.
2 Mistakes to Avoid When Making Your Chocolate Mug Cake
Overcooking the Cake
One of the biggest mistakes you can make is leaving your mug cake in the microwave for too long.
The key to a perfect mug cake is a quick bake, just 60 to 90 seconds.
Microwaves vary, so start checking at 60 seconds. If you leave it in too long, it could dry out and become more like a sponge than a fudgy dessert. Trust me, the texture is everything!
Using the Wrong Mug
Not all mugs are created equal. You want a microwave-safe mug that’s tall enough to let your cake rise without spilling over.
If your mug is too small or too wide, the batter might spill over as it cooks, making a mess in your microwave.
A good rule of thumb: Choose a mug that’s about 12 oz (350 ml) in size. This gives the cake plenty of room to rise while keeping it all in one place!

FAQs
Can I use hot chocolate powder in place of cocoa powder?
Yes, you can use hot chocolate powder instead of cocoa powder in your chocolate mug cake, but keep in mind that hot chocolate powder contains sugar and other ingredients, so it will make the cake sweeter. Overall, it’s a quick swap, but be aware that the flavor might be slightly different, more milky and sweet, rather than deep and rich like traditional cocoa powder.
Would baking soda work as a substitute for baking powder?
It’s best not to swap baking soda for baking powder in your chocolate mug cake. Baking soda requires an acid to activate it, while baking powder already has the acid built in. If you use baking soda instead, the cake might not rise properly and could end up with a slightly metallic taste.
Why is my mug cake not fluffy?
The reason might be overcooking, it’s easy to get excited, but microwaving it too long can make the cake rubbery rather than light. Try reducing the cooking time and checking the cake at the 60-second mark. Lastly, if you’re not using baking powder, your cake won’t have the rise it needs. Make sure to include it to help the cake fluff up nicely!
