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

Here’s a list of ingredients you’ll need to make this cake. You can find my recipe card at the bottom of this post for the complete list with their amounts.

  • Plain/all-purpose flour
  • Light brown sugar
  • Unsweetened cocoa powder
  • Baking soda
  • Salt
  • Ground cinnamon: Optional, but too good not to try!
  • Milk
  • Unsalted butter
  • Vanilla extract
  • Chocolate chips: I used milk chocolate chunks here.

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!

The printable recipe card with the FULL list of ingredients and instructions can be found at the bottom of this post.

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.

Microwave Chocolate Mug Cake

Microwave Chocolate Mug Cake

Yield: 1 mug cake
Prep Time: 10 minutes
Cook Time: 2 minutes
Total Time: 12 minutes

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!

Ingredients

  • 4 tablespoons (33g) plain/all-purpose flour
  • 3 tablespoons (42g) light brown sugar
  • 2 tablespoons unsweetened cocoa powder
  • 1/4 teaspoon baking soda
  • 1/8 teaspoon salt
  • 1/8 teaspoon ground cinnamon
  • 6 tablespoons (85ml) milk
  • 2 tablespoons (28g) unsalted butter, melted
  • 1/2 teaspoon vanilla extract
  • 2 tablespoons (30g) chocolate chips

Instructions

  1. In a large microwave-safe mug*, stir together the flour, sugar, cocoa powder, baking soda, salt, and cinnamon.
  2. Add the milk, butter, and vanilla, and stir until smooth and combined. Mix in the chocolate chips.
  3. Place the mug on a microwave-safe plate, and microwave on high for 1 minute 40 seconds or until the cake is cooked in the middle. (Timing is based on my 800W microwave so your timing might vary. See Recipe Notes below.**)
  4. Enjoy warm with a scoop of ice cream or your favourite toppings!

Notes

*You want a big enough mug that the cake batter fills up just over half way.

**All microwaves are different and can yield different results (like an overcooked mug cake). My microwave is 800W and I cooked mine on 100% power for 1 minute 40 seconds. Knowing this may help you better judge how long to cook yours for.

Microwave Watt Time Estimates:

700W - 1min 50sec / 800W - 1min 40sec / 900W - 1min 30sec / 1000W - 1min 20sec

For a more molten effect, cook for 15 - 20 seconds less.
