Microwave Mug Blondie Thee perfect single serve dessert that can be made in less than 5 minutes in the microwave

Microwave Mug Blondie

Save Recipe

Hi Bold Bakers!

Blondies are by far one the most popular baked goods around. For those of you who don’t know, a Blondie is like a brownie but without the chocolate. The result is a thick, moist and dense texture with a sweet caramel-like flavor. Well, now instead of taking 30-40 minutes to bake yourself a sheet of Blondies, you can make one in the microwave in just minutes! My Microwave Mug Blondie is the perfect single-serving treat. The best part is this baby can be made ahead and kept in the fridge, or simply warmed up for an after dinner treat or midnight snack.

I’m a strong believer in treating myself to something special every now and again. The trouble is it’s tough when sometimes you just want one slice of cake or one cookie but to get there you have to make an entire batch. This Make Ahead Microwave Mug Blondie is the perfect solution. Knowing I have dessert waiting for me at home really does bring me great comfort.

To prepare this Make Ahead Mug Blondie, I combine simple ingredients like flour, brown sugar, vanilla and butter. With the addition of chopped caramel candies and white chocolate chips, this Microwave Mug Blondie is perfection. I cover this up and pop it in the fridge so next time I need a sweet treat I know exactly where to go. All it takes is 1 minute in the microwave and before you know it, you have yourself the perfect little Microwave Mug Blondie. Just for you and in just minutes…who could resist?

    Hi Gemma,
    Do I need to make the batter 24 hours in advance for it to have that fudge-like consistency? Will it affect the texture of the finished product?

    • Gemma Stafford on May 30, 2018 at 5:40 am

      Hi,

      No just mix it up and cook it off straight away. When you decide to cook off your blondie won’t affect the texture.

      Best,
      Gemma.

    Do you have an estimated calorie count for this mug Blondie recipe?

    • Gemma Stafford on April 16, 2018 at 4:22 am

      Hi there,
      We will pay closer attention to this issue going forward, I know it matters to people.
      For this one I would say about 180 calories.
      There are a number of good calculator apps out there on the web, it is worth having one on hand.
      I hope this helps,
      Gemma 🙂

    • Sarah on June 12, 2018 at 5:13 pm

      There is about 800 not including caramel

      • Gemma Stafford on June 14, 2018 at 7:20 pm

        No it includes the caramel 🙂

        Gemma.

    I LOVE this Blondie Mug Recipe. I make it with Gluten Free Flour. Do you have a Recipe for a larger pan (8 x 8 pan) of Blondies? I can’t have Chocolate.

    Thank you

    • Gemma Stafford on April 6, 2018 at 6:54 pm

      I’m thrilled to hear that Bonnie. So we just tested a recipe for an 8×8 tin and it will be coming in the next 6 weeks.

      FYI It was soooooo good.
      Gemma.

  4. Chantese on March 7, 2018 at 6:44 pm

    This Blondie recipe is very delicious. I don’t have caramel candies or white chocolate so I stuffed mine with a some peanut butter

    • Gemma Stafford on March 8, 2018 at 3:41 am

      Hi there,
      Wow! you really know how to rock up a recipe, well done you,
      Gemma 😉

  5. Smriti Jhamb on February 25, 2018 at 5:50 am

    Hi Gemma
    Your mug recipes are so great. I just wanna ask why have you removed the recipe of celebration mug cake from your website?
    I wanted to try it. It looked so good.

    • Gemma Stafford on February 28, 2018 at 7:09 am

      Hi there,
      It is here! (https://www.biggerbolderbaking.com/celebration-mug-cake/). Not sure how you lost it, but it is still there, phew!
      Gemma 🙂

      • Smriti Jhamb on February 28, 2018 at 7:50 am

        Gemma, I clicked the link and it opened your website but there it was written that – ‘sorry that page doesnt seem to exist’.

        • Gemma Stafford on March 1, 2018 at 8:13 am

          Hi there,
          May have something to do with your browser. (https://www.biggerbolderbaking.com/microwave-mug-blondie/) here it is!
          Gemma 😉

          • Smriti Jhamb on March 1, 2018 at 8:21 am

            Hi Gemma
            Thanks for replying. But what I meant was the recipe of celebration mug cake on your website is not available. I told u that and u shared the link and I opened that link again and it opened your website but there was written that ‘sorry that page doesn’t seem to exist’ again.
            To show you how it is I have mailed you the picture to your email Id. Please do check it out.



          • Gemma Stafford on March 5, 2018 at 8:43 am

            Hi there,
            I did check it out, and so did Kevin, and it is opening for us!
            I do not understand what the issue is, I will get Kevin to respond to your mail, it may be your browser. Are you having trouble with any of the other recipes?
            We will figure it out,
            Gemma 🙂



  6. Aruora on January 22, 2018 at 2:39 am

    Hi Gemma
    I know the caramel candy is optional but I really want to use the candy and I bought the soft cream toffees instead 🤦‍♀️ can I use it instead ?

    • Gemma Stafford on January 22, 2018 at 7:22 pm

      Yes use those, they will work 🙂

  7. Judy on January 16, 2018 at 1:04 pm

    Gemma, can you be sure to include nutritional info on all of your recipes. Extremely helpful. Thanks much.

    • Gemma Stafford on January 17, 2018 at 3:22 am

      Hi Judy,
      Yes, and we intend to pay more attention to this this year. Thank you for bein in touch,
      Gemma 🙂

  8. Neha Agnihotri on December 15, 2017 at 6:30 am

    Hi Gemma,

    I used white sugar instead of brown, so the color was no that good but tasted good. I have tried few of your recipes till now and love how simple the method is and how few ingredients you us. I have two 6 month old kids and Time is important 😊. I absolutely love your recipes and I watch these videos while I feed my kids to keep myself busy. Thank you for posting you recipes and also keeping it so simple that even I think I can bake ( which have been my dream since long).

    • Gemma Stafford on December 16, 2017 at 7:06 am

      Hi there Neha,
      Good job, and many congratulations to you, sounds like you have a lovely family.
      Baking is a science, but it is not rocket science, and actually watching others cook is a good learning, baking is even better, and you will be an expert in no time at all.
      Thank you for being here with us,
      Gemma 🙂

  9. Ambika on November 10, 2017 at 12:29 am

    Can we use flavour less oil instead of butter?

  10. David Abboud on September 26, 2017 at 5:55 am

    Hi Gemma.
    I have tried over 15 of your microwave mug recipes, and I can say that your mug Blondie recipe is BY FAR the best microwave meal I have ever had in my entire life(I’m only 14 though). I would definitely recommend it.
    Can you please make a Blondie recipe ( oven ) ?
    Thanks

    • Gemma Stafford on September 26, 2017 at 10:12 am

      David, YES! I am really happy to hear this, though of course you have a long way to go before you are done!
      I do have this on my list, and will get to it before too long.
      I am really happy that you are getting on well with these recipes, stay tuned, there are more to come,
      Gemma 🙂

      • Tanu on October 6, 2017 at 3:04 am

        Hi Gemma!
        I stay in India, we don’t get the caramel candies you get. What do you recommend instead?

        • Gemma Stafford on October 6, 2017 at 6:32 pm

          You can leave them out if you can buy them. Just make sure you add the white chocolate chips 🙂

  11. Mira on September 10, 2017 at 12:47 pm

    It didn’t exactly turn out how it did in your video, but it was delicious anyway! Thank you!😁

    • Gemma Stafford on September 11, 2017 at 2:06 am

      Hi Mira,
      Good, and you have learned something. Think about it now and try again! I am happy that you are using the recipes. over-baking is the biggest issue with the microwave recipes!
      Gemma 🙂

  12. Dhriti on September 9, 2017 at 8:18 am

    I just made it and it turned out great.. I really appreciate ur effort to actually make some really tough desserts with simple ingredients and that to in a microwave 😊

    • Gemma Stafford on September 10, 2017 at 6:18 am

      Thank you Dhriti, so kind as usual,
      Gemma 🙂

  13. Sharon DiFalco on September 9, 2017 at 8:17 am

    The blondie mug cake was yummy. So delicious and so easy. I didn’t have the caramel candies but I wouldn’t let that stop me from trying the recipe. I so enjoy your channel. You have a lovely way of sharing your joy in the kitchen.

    • Gemma Stafford on September 10, 2017 at 6:19 am

      Hi Sharon,
      Thank you for that lovely review of the recipe, and very kind words too, i appreciate it,

  15. Saba on September 5, 2017 at 10:12 am

    • Gemma Stafford on September 6, 2017 at 8:24 pm

      you can use self rating flour just leave of the baking powder if you do that.

      Happy Baking!
      Gemma.

  16. Steff on September 3, 2017 at 6:23 am

    I just made this blondie and it turned out quite well. I didn’t have any white chocolate chips or caramel candy on hand so I stuffed my blondie with a tsp of nutella 🙂

    • Gemma Stafford on September 3, 2017 at 11:07 am

      Hi there,
      Good for you Steff, use what you have I say! and you did, well done,
      Gemma 🙂

  17. mansi on September 3, 2017 at 3:33 am

    Why all of my recipes turn out to be a cake like thing?

    • Gemma Stafford on September 3, 2017 at 3:51 am

      Hi there,
      I am not sure if this is a good thing, or a bad thing! Are you have difficulty with one recipe in particular?
      the usual difficulty arises with either over-baking, or under-baking. So, bake for 40 seconds, check it, if it is very soft return for 10 seconds, and cherck again, keep going until it is barely firm to the touch. That will do it!
      Gemma 🙂

      • mansi on September 6, 2017 at 6:43 am

        it’s with everything(almost), my tart also turned into a cake, don’t know why or how!
        well, thanks, i’ll try again.

  18. Harini on August 31, 2017 at 6:35 pm

    I saw this recipe and immediately went to my kitchen to try it out. I’m 14 and I’ve made my fair share of blondies, as they’re my favorite dessert. So I tried this out but used brown butter in place of the melted butter and ohmylanta these were out of this world good. I didn’t have any caramel candies so I replaced it with white chocolate and drizzled some of your fantastic salted caramel sauce on top. Thank you for this amazing cheat day treat Gemma 🙂 <3

    • Gemma Stafford on September 1, 2017 at 3:28 am

      Hi there,
      thank you for this, i am happy that you made it your own, well done you,
      Gemma 🙂

  19. Cathlyn on August 31, 2017 at 1:07 pm

    Hi Gemma,
    Just made the mug blondie and it’s delicious. I will be making this again for sure!
    However, in the ingredients it says water instead of milk 😉
