Microwave Chocolate Mug Cake – A deliciously moist and fluffy chocolate cake that is made in the microwave. It’s sweet, loaded with flavour, and is cooked in under 2 minutes!

Microwave Chocolate Mug Cake
Mug cakes. I thought they were pretty ‘meh’ at first. That’s until I started recipe testing them, and finally made this incredibly delicious chocolate mug cake.
This is the BEST Microwave Chocolate Mug Cake I’ve ever tried.
This chocolate mug cake is moist and fluffy, sweet (not at all bland), perfectly spiced with a hint of cinnamon, and studded with melting chocolate chips.
It actually tastes like a rich and fudgy chocolate cake!
This cake is perfect for when I want a quick chocolate fix, but don’t fancy baking a whole cake or a batch of brownies. Microwave in less than 2 minutes – done!

How to make Microwave Chocolate Mug Cake
To make this Chocolate Mug Cake, start by grabbing a large microwave-safe mug. Add the flour, brown sugar, cocoa powder, baking soda, salt, and cinnamon and stir together.
Next, add the milk, melted butter, and vanilla. Mix together until completely smooth and combined. Stir in the chocolate chips.
Place the mug onto a microwave-safe plate, and microwave on high power until the cake is cooked in the middle. For my 800W microwave, this took 1 minute 40 seconds.
See my Recipe Notes below for more information on cook times.
If you want a more molten effect (YES!!), simply cook your cake for 15 – 20 seconds less than the original time.
Carefully remove the mug from the microwave and enjoy warm. Try this mug cake with a scoop of ice cream – SO good!

NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements. Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.
