Lime Coconut Mug Cake

You know the “Put the Lime in the Coconut” song? (Officially its title is “Coconut” by Harry Nilsson.) Mr. K loves singing that song, except he only knows one verse. So for the last few weeks he’s been singing/repeating “Put the lime in the coconut.” Then, while watching a marathon of the tv show Bones, it was sung during the end of one episode, so we finally both got to hear all the lyrics.

Well I’ve had the song stuck in my head, inspiring me to want to make something with limes and coconuts. I’ve come up with a few ideas, but I decided to start with this easy mug cake.

The lime and coconut do go well together. It’s fluffy, light and not too sweet because of the lime zest.

Update: If you enjoy this recipe, I just finished writing an entire book on mug cakes, featuring 100 recipes. You can pre-order it on Amazon.

Lime Coconut Mug Cake

Ingredients:

4 tbsp all purpose flour
1/4 tsp baking powder
2 1/2 tbsp granulated sugar
4 tbsp full fat coconut milk
1 tsp coconut flakes
1/4 tsp lime zest

Directions:

Combine all ingredients except lime zest and coconut flakes into a microwave safe mug. Stir with a small whisk until batter is smooth. Make sure you get all the flour, sometimes it gets stick around the edges of the mug. Briefly mix in coconut flakes and lime zest. Microwave for about 1 minute. Top of cake should be dry and look finished. Top with additional lime zest before eating.

  1. Hello Kirbie! First of all, I love your blog and all of your posts! I come here every single day <3
    And I absolutely love your mug cake recipes! The first one I tried was the blueberry mug muffin with streusel topping, and worked so well I wanted to try all of your mug creations!
    So, I created a recipe for an amazing and ridiculously easy mug cake, an ice cream mug cake! I would be honored if you could try it out.
    Ingredientes:
    30g of ice cream of choice (I used strawberry)
    2 tablespoons of all-purpose flour
    1/4 teaspoon of baking powder

    Directions:
    1. In the microwave, melt the ice cream for about 10 seconds.
    2. Then add in the flour and the baking powder and mix it.
    3. Microwave it for 50sec – 1min and it's done!

    • Thanks for commenting! I would love to try out your mug cake recipe. I will try it out soon and report back. It sounds delicious! I’m wondering it it has a bready texture, as I’ve made quick bread using only ice cream and self rising flour.

  2. Yum! So many mug cakes are chocolate or apple based. Coconut is a nice change. Can’t wait to make this one. Thanks muchly.

  3. How much lime juice?

  4. How much lime juice? Your recipe only shows lime zest!

  5. nice to see a mug cake that is different. and I can’t get the song out of my head now…. last week I made something and they started singing- “sweet dreams are made of these” . so I am happy to get another tune going.

    but have to say it does not get a good mark for visuals. what can I put on top to make it browner?

    • there really is no way to make a cake browner because it’s cooked in a microwave and not an oven. you can always decorate with frosting if you want a nicer appearance

  6. yeah i know its made in the m/w i thought you might have a trick up your sleeve to make it darker. i will try it and serve it with some ice cream, whipped cream, berries or something. i will be making it on a boat- i will let you know how it goes.
    thanks

  7. have you ever tried doing some kind of brown sugar type topping? maybe with some chopped macadamias? just to cover up a bit?

  8. Why does the coconut milk have to be full fat?

  9. For garnish, how about a very thin slice of lime twisted?  Not particularly to eat but would be a fresh topping for the white cake.

  10. Hi Dear… I love coconut so tried this recipe and got the same texture as seen in the picture above but the taste is too floury ….. Can i add butter in that recipe ???? If yes than how much should i use?

    • I’m not sure why it would be floury. Did you make sure you use full fat coconut milk? not coconut milk that is diluted with water (which is a lot of the Asian brands). But regardless, I would say maybe add 1/2 tbsp vegetable oil, but not butter.

  11. This sounds delicious! Do you think I could use coconut cream somehow? I don’t have coconut milk, but I don’t whether cream would work.

  12. instead of using vegetable oil  why not coconut oil …  Amina  and Kirbie ? Healthier and continuity of flavour … Looking forward to trying this. 🙂

  13. hey bro, just wondering, could I make this recipe in a batch and bake it in an oven? cause I really like the texture it gets, but my family is coming over, so instead of messing a lot of mugs I thought about that… do you think it would work out? Great recipe btw!

    • this is designed more for microwave cooking rather than making a batch for the oven. if you’re looking to make a full cake in the oven i’d recommend using a recipe for a full cake rather than trying to convert the mug cakes into one big batch

  14. Would you consider including nutritional information for each individual or group of similar recipes?

    • sorry but there are several websites that you can input recipes to find nutritional information but it is not something I provide.
