It’s almost crazy how many different forms of coconut there are these days. Coconut milk, coconut creamer, coconut water, coconut oil, coconut sugar, coconut flakes. I briefly considered trying to make every ingredient in this mug cake coconut but that seemed too extreme. Plus, unless you have all the ingredients on hand, that’d be a lot of extra items you’d need.

My main reason for making this coconut mug cake was because I wanted to work with coconut oil. I’ve seen it in grocery stores, I’ve seen it become more common in recipes, but until now, I’ve never used it.

I wish I had remembered to take some photos. I bought a small jar while grocery shopping and set about experimenting with it. I was surprised to find that it’s solid, like shortening. I had to heat it up to get it work with my recipe.


  • Coconut oil
  • Vegetable oil
  • Fat-free milk
  • Canned coconut milk
  • All-purpose flour
  • Granulated sugar
  • Baking powder
  • Sweetened coconut flakes

Recipe Steps

In a 12-ounce microwave-safe mug, melt the coconut oil in the microwave for about 20 seconds and then whisk until it becomes liquified.

Add the vegetable oil, milk, and coconut milk. Then add the flour, sugar and baking powder. Stir with a small whisk until batter is completely smooth. Mix in the coconut flakes.

Microwave the cake for approximately 1 minute and 30 seconds. The top of cake should be dry to the touch.

Be careful not to cook the cake too long otherwise it will be rubbery. Let it cool a few minutes before serving or adding the toppings.

Topping Ideas

For toppings, you can either use regular whipped cream and some toasted coconut flakes or you can make a coconut whipped cream (but this will need preparation ahead of time).

The coconut oil really adds another layer of coconut flavor to this recipe that is very enjoyable. It took me quite a long time to get this recipe right. We’re talking half a dozen trial runs and a whole lot of dirty mugs in my sink. And I was honestly getting a little sick of tasting them. But then this one came out and it was perfect. I had no issue finishing the whole thing.

If you enjoy this recipe, I have an entire collection of mug cake recipes including a Lime Coconut Mug Cake which is so easy to make.

I also wrote a book* on mug cakes!

  • 1 tbsp solid coconut oil
  • 1/2 tbsp vegetable oil (see note)
  • 2 1/2 tbsp fat free milk (see note)
  • 2 tbsp canned coconut milk
  • 6 tbsp all purpose flour
  • 4 tsp granulated white sugar
  • 1/2 tsp baking powder
  • 1 tbsp sweetened coconut flakes plus additional flakes for topping


  • In an oversized microwave safe mug (must hold at least 12 oz), scoop in the coconut oil. Microwave for about 20 seconds and then whisk until it becomes liquid and chunks dissolve.
  • Add in vegetable oil. milk, coconut milk. Then add in flour, sugar and baking powder. Stir with a small whisk until batter is completely smooth. Add in coconut flakes and stir a few times.
  • Microwave cake for approximately 1 minute and 30 seconds. Top of cake should be dry to the touch. Careful not to cook the cake too long. Let cake cool a few minutes before serving as is, or garnishing.
  • For toppings, you can either use regular whipped cream and some toasted coconut flakes or you can make a coconut whipped cream (but this will need preparation ahead of time).


  • I found that if you only using coconut oil, the cake comes out a little dry which is why this recipe uses both vegetable and coconut oil.
  • Usually other milks work for my recipes but I found when I tried using whole milk, the recipe came out too dry so I recommend fat-free milk.

  1. I’ve tried many mug cakes and this definitely has the best texture!! I like to refrigerate my canned coconut milk so that it separates, and then use the watery part in place of the nonfat milk, and the solid creamy part for the coconut milk. Also, I always add a pinch of sea salt which really brings out all the coconut flavor! 

  2. what is your recipe for coconut whipped cream?

  3. Would Almond milk work in place of fat free milk?

  4. My version of this recipe uses self-rising flour instead of regular + baking powder. Also, I have found that 2tbsp half/half milk and 3tbsp of canned coconut milk will result in a delicious slightly moist mug cake (microwaved for 2 minutes, 20 seconds at 600W).

    That being said, I didn’t realise there was a diffirence between canned coconut milk and drinkable coconut milk until i went ahead and actually bought canned XD. Thank you for this recipe, it satisfies my need for coconut cake EVERY TIME.

  5. Will this recipe turn out good if i multiply it to make a big 8 inch cake ?

    • No, this recipe is designed specifically to be one serving for the microwave. For a full cake you would have to make a lot of adjustments as well as adding eggs for the cake’s structure.

  6. This mug cake had the best texture of any (and there have been a lot) that I have tried. Very fluffy and moist! The only thing I changed was to use cashew milk instead of nonfat milk, because I only had full fat milk otherwise. I would have prefered it a tad sweeter, so next time I’ll try adding a smidgen more sugar and hope it doesn’t mess with the texture too much. Thanks for the recipe!

  7. This is my favorite cake, however I’m type 2 diabetic & have to watch my carbs. Any idea what they are in this cake. Looks like I might be able to have a bite but once I got started I’d eat the whole thing which is a no-no.

    • sorry I don’t have that information. I’d suggest looking for a nutritional website that provides recipe/ingredient analysis

  8. This is amazing! I didn’t read the recipe correctly and didn’t melt my coconut oil first, but it was very soft so it didn’t seem to affect anything I used Silk Coconut Milk in place of the fat free milk, but did use the canned coconut milk when called for. I didn’t have any coconut unfortunately and I’m sure it would have been even better if I had, but I still loved it! Thanks for posting.

  9. What kind of consistency should the batter be?? I follwed the recipe but the batter was really thick so I decided to add a bit more milk, which did not work out lol. The addition of salt takes the taste to a whole another level!! I try this again soon

  10. If i use unsweetened coconut , how much more sugar should i add?

  11. I loved the taste of it but it turned out very gummy. My only deviation was to use all coconut milk can that be why? So I poured on a little more coconut milk, topped with mangos and ate it like a trifle /pudding instead nomnom =)

    • yes that is definitely why. that’s why I used two diff kinds of milk because all coconut milk just didn’t come out right

  12. This mug cake looks devine! I LOVE coconut, although I’ve also never used coconut oil before. I actually didn’t realize it had a coconut flavor! 

  13. This is a unique & interesting concept – something different to do, with respect to coconut. I will have to try.
    I like recipes w/ coconut milk .

  14. I’m always confused when recipes call for “coconut milk”, is it the drinkable kind like So Delicious brand in a carton or the canned coconut milk used for cooking curry and stuff?

    • good question. I’m going to add that to the recipe. I used canned coconut milk for this, but I think the drinking kind might work too

      • No the drinking kind has extra water, coconut milk is the tinned kind for cooking much more coconut in it x
