    What is a mug cake?

    I still seem to get this question a lot so I’ll just clear it up before we get into the nitty gritty.

    A mug cake is literally as it sounds. A cake that is made in a mug.

    A microwave-safe mug! This is not one for the oven.

    Is this one still without eggs?

    Yes, this one is still egg-free!

    Can I make this in the oven?

    This recipe for espresso chocolate mug cake is specifically for the microwave.

    I can’t find espresso powder.

    You could grind up some coffee beans and substitute that.

    What kind of espresso powder?

    Honestly, any kind works in this since you are just mixing it with the dry ingredients.

    I used instant espresso powder.

    Can I grind up espresso beans and use that instead?

    Yes, I would do a very fine grind.

    Can I pour espresso shots into the batter instead?

    You could but you would likely need to make sure that the flour to liquid ratio is correct otherwise your batter will be really runny and it would take longer to cook.

    Will this mug cake keep me up at night?

    Depends on how sensitive to caffeine you are.

    If you are sensitive, then I suggest using decaf or having another mug cake flavor.

    Can I put something else in the center of the mug cake?

    Absolutely!

    Ingredients

    • 1/4 cup all-purpose flour
    • 2 tablespoon unsweetened cocoa powder
    • 1 tablespoon instant espresso powder
    • 1/4 teaspoon baking powder
    • 2 tablespoon granulated sugar (you can add 1 tbsp. more if you like it a bit sweeter)
    • 1/8 teaspoon salt
    • 1/4 cup + 1 tbsp. milk
    • 2 tablespoon vegetable oil
    • 1 tablespoon mini chocolate chips

    Instructions

    • In a medium bowl, whisk together dry ingredients.
    • Whisk in the milk and vegetable oil until all ingredients are combined and batter has no clumps.
    • Pour batter into a microwave-safe mug. Mine was a 14-ounce mug. You want enough head space for the cake to rise without pouring over.
    • Add mini chocolate chips in the middle of the batter. Just drop it in the middle, no need to push it down and sink it in the batter. It does that on its own when it cooks! :)
    • Place a paper towel into the microwave and set the mug on top (this is to catch any batter if your mug cake overflows).
    • Microwave mug cake for 70 seconds on high (PLEASE READ NOTES CAREFULLY BELOW)
    • Carefully remove from microwave and enjoy!

    Notes

    Please note that ALL microwaves are different therefore can yield different results and can overcook this mug cake if you aren't careful. My microwave is 950 watts and I cooked mine on 100% power for 70 seconds*. Knowing this information, it may help you better judge how long to cook yours for and at what power.
    **This recipe is specifically made for the microwave. I developed it for the microwave. I don't know cook time or temperature for an oven...I'd imagine it'd be a very quick cook time at a low temp., but since I didn't test the recipe for an oven, I cannot give specifics. Sorry!
    No eggs? Correct. There are NO EGGS in this recipe. Why? Egg is what makes the mug cake spongy. If you think about it, when you bake a full-sized cake, you typically use 1 or 2 eggs...for a mug cake to use 1 egg is A LOT!
    Self-rising flour? I have tested this with self-rising and it does NOT work. At least I felt it didn't work because it was too spongy for me. You are more than welcome to use it, however, please keep in mind that I don't recommend this method.

    Would love to try this but the calories for one serving seem SO high! Is this accurate? 600 calories??

    • Julie Wampler says:

      I just plugged the ingredients into my fitness pal and that’s what it returned to me so i assume it is correct!

  • Ines says:

    Tried this last night…it was delicious! If you have a sweet tooth definitely add in the 3rd tblsp of sugar but I thought it was the perfect sweetness especially since I added a scoop of vanilla ice cream.

    • Julie Wampler says:

      Thanks so much, Ines! Glad you enjoyed it!

  • fatema says:

    The cake was decadent and beyond anything I have ever made in a microwave (and I have made quite a lot, trust me). Thanks for this wonderful recipe. I am keeping this one for my late-night coffee cravings.

    • Julie Wampler says:

      Awesome! Wonderful to hear.

  • Vishal says:

    Can we use milk powder instead of milk? can we add water also? If yes for water what are the substitutes and modifications in the recipe and quantity of water to be used for any mugcake flavor?

    • Julie Wampler says:

      you’re asking questions that i didn’t test the recipe with so unfortunately, i don’t know the answers! sorry.
