Why I Love This Triple Chocolate Mousse Microwave Mug Cake

It’s my go-to when I want a little treat without spending hours in the kitchen. My whole family loves it, especially my little brother, who always asks for seconds.
The best part?
You can change it up! I love adding different kinds of chocolate – sometimes, I use extra dark chocolate for a richer flavor or white chocolate for a sweeter one. I think you’ll agree that this is the best quick chocolate mug cake ever.

Ingredients for This Decadent Triple Chocolate Mug Cake
Okay, let’s gather the stuff you need. It’s really simple!
- 4 tablespoons all-purpose flour
- ½ teaspoon vanilla extract
- 3 tablespoons granulated sugar
- 2 tablespoons white chocolate chips
- 2 tablespoons unsweetened cocoa powder
- 2 tablespoons milk chocolate chips
- ⅛ teaspoon baking powder
- 2 tablespoons dark chocolate chips
- ⅛ teaspoon salt
- 3 tablespoons whole milk
- 2 tablespoons vegetable oil
- Whipped cream, for topping
- Chocolate shavings, for garnish (optional)
I’ve found that you can use any kind of milk you have. If you don’t have vegetable oil, you can use melted butter instead. And if you’re a fan of white chocolate, throw in a few extra white chocolate chips! You just need a microwave-safe mug for this recipe, that’s it!
How to Make This Easy Triple Chocolate Mousse Cake
Ready to make this super quick chocolate mug cake? It’s so easy!
- First, grab your microwave-safe mug. Put in the flour, sugar, cocoa powder, baking powder, and salt. Whisk it all together with a fork until it’s mixed up. Don’t skip this step! It makes sure your cake isn’t lumpy.
- Now, pour in the milk, vegetable oil, and vanilla extract. Stir it all up until the batter is smooth and there are no more lumps.
- Time for the best part – the chocolate! Gently fold in the white, milk, and dark chocolate chips. Make sure they are spread around in the batter.
- Pop the mug into the microwave and cook on high for 2 minutes. The cake will puff up and be set in the center.
- Take it out of the microwave and let it cool for a couple of minutes. Trust me, it’s hot!
- Finally, top it with a big dollop of whipped cream and some chocolate shavings if you have them. It makes it look super fancy!

I’ve learned that overcooking this Triple Chocolate Mousse Microwave Cake will make it dry, so stick to the 2-minute cook time. The smell of the melting chocolate will fill your kitchen, it’s wonderful!
Making It Extra Special
You know how sometimes you want to make something a little extra? Here’s how! I love this instant mousse cake with a scoop of vanilla ice cream – it’s like the best ice cream sundae ever! This is perfect for a cozy night in. If you’re feeling fancy, you can sprinkle a bit of powdered sugar on top. You can also add some nuts for crunch, or try it with dairy-free milk and chocolate chips to make it vegan.
Common Questions I Get About This 2-Minute Triple Chocolate Mousse Cake
Okay, here are some of the questions people ask me about my quick chocolate mug cake.
Can I make this ahead of time?
I wouldn’t. It’s best when it’s warm and fresh. You can prep the ingredients in a mug, but don’t cook it until you’re ready to eat!
Can I substitute X for Y?
Sure! If you don’t have all-purpose flour, use a gluten-free blend. If you don’t have vegetable oil, melted butter works perfectly. And if you’re out of a certain type of chocolate, just use more of the other kinds.
What if I don’t have chocolate shavings?
That’s okay! You can use some sprinkles or even just enjoy it plain.
My cake is too dry/too wet!
This usually means that the microwave cook time wasn’t correct. A bit less time for a gooier cake or a bit more for a drier cake. All microwaves are different so it might take a time or two to get it perfect.
