What Size Mug Do I Need for this Mug Cake?

You will need a 12 to 14-ounce microwavable mug. A 16-ounce mug works fine too with a bit more room at the top for decadent toppings.

Can I add instant espresso to this Mug Cake?

Absolutely! I’ve not included instant espresso in the ingredient list, but it’s easy to add a pinch (maybe 1/8 teaspoon) with the flour for an even richer Christmas Chocolate Mug Cake

Tips on Microwave Mug Cakes

The most important tip for a successful mug cake is mixing the ingredients really, really well. While it’s super easy to mix the ingredients in the mug, sometimes it doesn’t get thoroughly combined.

I like to recommend mixing the ingredients in a separate bowl with a whisk so that you can actually see that ingredients are fully incorporated.

How Long Do You Microwave a Mug Cake?

As you know, microwaves vary, even those with similar wattages. This Christmas Mug Cake is perfectly cooked in my 1000 watt microwave in 70 seconds.

I recommend checking the cake at 1 minute and adding time in 5-second intervals. You want the top to be “just” set. Be sure to let it cool a couple of minutes too.

2 Minute Christmas Chocolate Mug Cake

Yield: 1 serving
Prep Time: 1 minute

Total Time: 2 minutes

Get festive with this oh-so-simple Christmas Chocolate Mug Cake, in 2 minutes. It's chocolatey and delicious, dense and rich, and perfect for the holidays. Treat yourself to a decadent dessert in minutes. Plenty of time for that Christmas movie you've been meaning to watch!

Ingredients

  • 1/4 cup all-purpose flour
  • 2 tablespoons unsweetened cocoa powder
  • 2 tablespoons granulated sugar
  • 1/4 teaspoon baking powder
  • pinch of salt
  • 1/4 cup milk
  • 2 tablespoons cooking oil
  • 1/4 teaspoon pure vanilla extract
  • 1 tablespoon semi-sweet chocolate chips

Instructions

  1. You will need a microwave-safe mug that is 12 to 14 ounces.
  2. In a separate mixing bowl, whisk together the flour, unsweetened cocoa powder, granulated sugar, baking powder, and salt until well combined. Add the milk, oil, and vanilla extract; continue whisking until fully combined.
  3. Pour the batter into the prepared mug and sprinkle chocolate chips on top.
  4. Microwave for 60 to 90 seconds, the center of the cake should be just set. In my microwave (1100 watts) it takes about 75 seconds. But all microwaves are different. I recommend cooking for 1 minute and then testing the cake.
  5. Remove the mug from the microwave and let cool for a few minutes. Top with whipped cream, crushed candy cane, sprinkles... whatever you have on hand that is Christmasy and festive. Enjoy!
