What is Easy Hot Chocolate Mug Cake?
The Easy Hot Chocolate Mug Cake is a fun and fast dessert that brings all the cozy flavors of classic hot chocolate into cake form. It became popular thanks to the rise of microwaves and the love for fast, no-fuss desserts.
Think of it as your favorite hot chocolate cake, but quicker! It’s made by mixing all of the ingredients in a mug, zapping it in the microwave, and voilà—you get fluffy cake batter turned into a soft, moist cake. It’s a cozy go-to for the colder time of year and is great for when you don’t feel like baking a whole cake.

Ingredients
Instructions
In a large microwave-safe mug or bowl, add the dry ingredients: flour, sugar, and cocoa powder. Stir in the wet ingredients: milk, egg, oil, and vanilla extract. Add a pinch of salt. Mix well until the cake batter is smooth.
Microwave on high for 2 mins. Check doneness with a toothpick—it should come out clean or with moist crumbs. Let it cool slightly, then enjoy it with your favorite toppings!
Top Tips
To keep your mug cake super moist, don’t overcook it—microwave for exactly 2 minutes and let it sit for a minute to finish cooking through.

Notes
Mari says
I was wondering if I can make this chocolate mug cake in a rice cooker? I mean instead of using a mug I just put it directly to a rice cooker and cook it.
I am really hoping for you feedback.
Thanks! 🙂
