Hi Bold Bakers!

Ok, time for some trivia, what is the most iconic flavor when it come to cake…? I bet all of you can agree it’s good old Funfetti! Just saying the word makes me feel all kinds of warm and fuzzy. From Birthday parties to family get togethers no festive celebration is complete without a bit of color, sprinkles, sweetness and vanilla cake. And that’s why Funfetti really does the trick. It’s all that baked into one tender spongy cake, topped with bright or pastel frosting and enjoyed by all. But sometimes you want a single-serving version or a little cake fast, so that’s where my 1 Minute Microwave Funfetti Mug Cake comes in.

Whether you’re a kid or an adult you probably love Funfetti Cake. The thing is you usually don’t get to enjoy this treat any given day. Well now you can with my 1 Minute Microwave Funfetti Mug Cake. Just like you, I love this fun flavor but don’t exactly want to make a whole cake just to have one slice. That’s why I created this single-serving gem of a mug cake.

This Funfetti Mug Cake is made super moist and tender from the milk and butter and perfectly flavored with sprinkles and vanilla to really deliver on the “fun.” I think this recipe is perfect for any dorm room celebration or after school treat. Let me remind you, birthday cake tastes just as good on days that aren’t your Birthday. Every day is one to celebrate. If you have a minute to spare and a few basic ingredients this special treat is all yours. Enjoy!

    I am sure this would’ve tasted better but it tasted like I had added to much flour and I am not sure if I baked it too long or maybe not long enough?

    • Gemma Stafford on May 31, 2018 at 6:26 am

      Hi Allegra,

      I’m sorry to hear that. These little mug cake take such a short time to cook. Check after 45 seconds and it will almost be done. This should solve your problem.

      Best,
      Gemma.

  5. Emma on May 11, 2018 at 1:57 pm

    This came out way to buttery and smelled like a popover

    • Gemma Stafford on May 12, 2018 at 3:39 am

  6. Amanda on March 28, 2018 at 8:45 pm

    This was not the best recipe I have tried at all

    • Gemma Stafford on March 29, 2018 at 2:47 am

      Hi Amanda,
      I am sorry to hear this. Tell me what happened and I will try to resolve the issues with you,

  7. aaleen on March 26, 2018 at 11:22 am

    my cake was raw

    • aaleen on March 26, 2018 at 11:25 am

      i don’t know why but i also added a bit of nutella and it tasted great

    • Gemma Stafford on March 30, 2018 at 4:22 am

      Hi Aaleen,
      I think I got to this already, but to be sure!
      I think it is to do with the mug/cup you are using. It needs to be wider than deep, and you need to bake until it feels firm to the touch on top, not hard, but barely firm. keep going, give it another try,
      Gemma 🙂

  8. Muhammad Ali on March 25, 2018 at 9:28 am

    hello gemma
    my cake hardly took 2 minutes to bake
    why

    • Gemma Stafford on March 25, 2018 at 9:14 pm

      Thats ok. Everyones microwave is different. As long as it was cooked and delicious then all good 🙂

      Gemma.

    • aaleen on March 26, 2018 at 11:19 am

      Hello gemma !
      i have tried ur first cake ever and turned out to be raw at the end !why did it happen

      • Gemma Stafford on March 29, 2018 at 4:37 am

        Hi there Aaleen,
        I think I responded to this already, but just in case.
        There can only be two reasons:
        1 you did not bake it for long enough.
        2. the cup/mug you used was the wrong shape. This matters. wider than deep is best, this is because of the way microwaves distribute the heat in a bake.
        A small cereal bowl will work well for this recipe too, but a tall deep mug is not so good,
        Gemma 🙂

  9. Muhammad Ali on March 25, 2018 at 8:33 am

    amazing and colourful cake

    • Gemma Stafford on March 25, 2018 at 9:14 pm

      I love to hear that 🙂

  10. Caroline on February 21, 2018 at 8:56 am

    Hi Gemma

    This funfetti recipe doesn’t mention the required amount of sprinkles. When adding should I reduce the sugar accordingly 1:1. Ie swap 1 tablespoon sugar for sprinkles? Err

    • Gemma Stafford on February 22, 2018 at 4:39 am

      Hi Caroline,
      OOPS! I have no idea where this quantity went, I will attend to it.
      I suggest you add about one teaspoon per mug recipe, you can adjust the sugar too if you wish to do so, by the same amount.
      Sorry to confuse, I will fix it,
      Gemma 🙂

  11. Debra Peterson on January 6, 2018 at 7:23 pm

    Absolutely perfect first time through! Have no idea how to send you a picture, but they are so cute. I worried that they wouldn’t raise without leavening (baking powder, soda etc), but they turned out great! And delicious! Thanks Gemma!

    • Gemma Stafford on January 7, 2018 at 3:28 am

      Hi Debra,
      Great! Happy to hear this.
      At the bottom of each post is a ‘submit your own photo’ button, have a go, it is great to see the hard work, and really encourages other Bold Bakers,
      Gemma 🙂

  12. Itsjojosiwa on October 13, 2017 at 6:34 pm

    It did not work I think because of the egg it came really hard

    • Gemma Stafford on October 14, 2017 at 7:19 am

      Hi there,
      It was hard because you over-baked it!
      When the cake looks and feels firm to the touch it is baked, stop it, take it out, allow to stand. The heat continues to distribute when it is out of the oven, firming it up further. Try it again, you have learned something,
      Gemma 🙂

    • Rhiannon on January 4, 2018 at 10:51 am

      The same happened to me but the cake wasn’t done at the bottom only the top.

  13. Hannah on October 9, 2017 at 5:48 pm

    Good, but I would wait to add the egg because if you add it to the butter right away it starts to cook. It took longer than 50 seconds to cook.

    • Gemma Stafford on October 10, 2017 at 1:55 am

      Hi Hannah,
      did you add it to hot butter? If so, yes, it will cook the egg. just barely melt the butter, it will not then be hot enough to cook the egg.
      Glad you tried this one!
      Gemma 🙂

  14. Roxana on September 9, 2017 at 9:46 am

    Tried this out, and came out good. An easy one for one person when you are craving for something with your tea.

    • Gemma Stafford on September 10, 2017 at 5:21 am

      Thank you Roxana for all of your lovely reviews,
      Gemma 🙂
