Remember last week I was telling you about my water bottle and how I lost it at a nail salon and then my Pure Barre instructor found an extra one in the back storage and I was finally reunited with my water bottle? Well, you won’t believe this but I lost it again.

5 days after having been reunited with it.

This time, it flew out of a car window. On the interstate. Going 70mph. No joke.

I really wish I were kidding but I’m not. A huge bug landed on me while we were driving home on Thursday and if you know anything about me, you know that I hate bugs. Like haaate and get really sweaty and have an anxiety attack. It landed on me and the window was open so Jason told me to just flick it out the window. I did that but it didn’t go out the window. Instead, it landed on my lunchbox. I tried to flick it off my lunchbox but it wouldn’t come off so my BRILLIANT idea was to hold the handles of my lunchbox and put it out the window and hope that the wind would take the bug with it. Nope, didn’t work. So then I shook the lunchbox. You see, my lunchbox has a little water bottle holster thing and in my freakout moment, I obviously wasn’t THINKING. On the second shake, we watched something fly out. was my water bottle. RIP water bottle.

The bug was still in the car and I lost my beloved water bottle.

Damn bugs.

So I wasn’t kidding you when I said you should make a batch of salted caramel because you’re going to need it in this salted caramel apple spice mug cake!

Have you tried my other mug cakes? The chocolate one is the most popular and then the vanilla one for those that don’t want something that rich.

If you’ve tried my other mug cakes then you know what you’re in for. Moist, fluffy, and the best kinda dessert ever! Since it’s apple season, I figured I’d come up with an apple-flavored one. Drizzle the salted caramel all over the top and omg, best dessert ever! You can share but it’s single-serving so sharing is definitely optional ;) it took me 7 tries to finally get this to be the texture I wanted and I hope you enjoy it just as much as we do!! :)

Salted Caramel Apple Spice Mug Cake
Prep Time

Cook Time

Total Time
3 mins

Less than 5 minutes gets you a single serving cake to satisfy that sweet tooth!

Servings: 1
  • 1/4 cup all-purpose flour
  • 1/2 teaspoon apple pie spice
  • 1/2 teaspoon baking powder
  • 3 tablespoons granulated sugar
  • Pinch of salt
  • 1 1/2 tablespoons unsweetened applesauce
  • 2 tablespoons milk
  • 1 teaspoon vegetable oil
  • 1 teaspoon water
  1. In a small bowl, whisk together the dry ingredients.
  2. Make a well in the center of the dry ingredients then add the wet ingredients. Whisk everything together until combined and no lumps remain.
  3. 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.
  4. Place a paper towel into the microwave and set the mug on top (this is to catch any batter if your mug cake overflows).
  5. Microwave mug cake for 1 minute and 50 seconds on high (PLEASE READ NOTES CAREFULLY BELOW)
  6. Carefully remove from microwave, drizzle your homemade salted caramel sauce (or you can use a store-bought caramel sauce) on top and enjoy!
Recipe 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 1 minute and 50 seconds. Knowing this information, it may help you better judge how long to cook yours for and at what power. This batter is wetter and more moist than my other mug cakes hence the longer cook time. If you feel that your batter is still too wet after 1 minute and 50 seconds, feel free to zap it a little longer.

Yes, no eggs in this either. Eggs is what makes typical mug cakes spongey!

**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!

    Sorry about the water bottle ;)

  3. 09/22/2014 at 7:42 am

    OMG! I feel you. I have been using the same water bottle forever and I have lots it so many times. Luckily, it always comes back, but I feel alone without it!
    Oh, and this mug cake? HOW DID YOU MAKE IT SO GOOD. Mine always tastes like a sponge.
    Not that I know how those taste… Pinned!

    I know the importance of a favorite water bottle. I just left mine at a Relay For Life summit in Dallas. I really miss that bottle (it was my woobie). BTW can’t wait to try the cake. Looks amazing!

    Completely relate to the bug incident – I am exactly the same, I just wish they would all leave me the heck alone so I don’t have to get all panicky – anyways, this mug cake looks absolutely perfect – definitely not for sharing!

  22. 09/23/2014 at 12:23 pm

    I’m so sorry to hear about your water bottle :( not cool bug ~ not cool at all!!

    This cake looks amazing … I LOVE mug cakes, especially since they are usually so easy to make!!

      Great to hear! So glad you enjoyed it!

  26. 11/07/2014 at 9:48 pm

    It was easy and tasty. It certainly satisfied my sweet tooth with this one serving size. I would make it again. I did not have the sauce which might have made it fabulous but used a dollop of whipped topping. Thanks for sharing.

    This was really good! I usually am not happy with mug cakes, but this turned out really delicious. I only used 2 tablespoons of sugar. And my daughter and I were very happy with it … I am going to try a gluten-free version and I’m sure it will be wonderful as well !

    How do you get mug cakes to come clean out of their containers? Should you grease the mug, or just wait for it to cool before taking it out? (it’s a long wait when you smell that cake!)

    • Julie
      09/04/2016 at 7:43 am

      Yes, you could lightly grease the mug if you want!

    I am a pudding fan, but my family is not. Have you ever tried making tapioca pudding (using Minute Tapioca) in a mug? The commercial cups are just too gummy and chewy for me.

    • Julie
      09/14/2016 at 7:02 pm

      I’ve never made pudding in a mug, sorry!

    I tried your recipe but I had a banana going bad and couldn’t throw it away so I made banana nut bread. It was great! Thanks

    Just wanted to thank you so much for posting this recipe. The cake turned out nice and fluffy. I didn’t have applesauce so I increased the milk to 3 1/2 T. I had an apple so I chopped up half of it, nuked it in the microwave for a minute or two to soften up, and then sprinkled it in between layers of the batter. It was yummy! Totally satisfied the carb craving.
