Chocolate Coconut Malibu Rum Cake

Let’s get boozy with Malibu!

The simplicity of this sheet cake is dedicated to that working individual, to the run-around-town busy parent, and to that student who strongly desires cake before sitting at the desk for hours.  Whatever situation you fall in, this is that simple cake for you.

I know, I know.  Some of you foodies and bloggers may look at this and think, “Ew, why from the box?”  Well, let me tell you, there’s absolutely nothing wrong with baking a cake from a box, mm-okayy?

When life gets tough from extended shifts at the job, several projects with close deadlines and obligatory family functions over the entire weekend, whippin’ up something fast is just what I need with the least amount of kitchen time.  For this reason, I always resort to my never-fail friends of Betty Crocker, Duncan Hines and Pillsbury and I’m not ashamed to say it.

So yea, in case you’re just checking in for the first time, I’ve baked from scratch.  Hell, most of what I make is from all raw ingredients but today, not this one.  If you’re looking for a delicious moist chocolate cake recipe (from scratch) see here and you most certainly can substitute it for the boxed version.

Now, onto how great this cake tastes!

Chocolate Coconut Malibu Rum Cake | URBAN BAKES

It has the most tender delicate crumb I’ve ever had, EVER.  Obviously due to the cream and rum-Hello!

It’s perfectly moist leaving your mouth a little numb with rum. Just perfect.  And with a light coat of rum-flavored whipped cream topped with shredded toasted coconut, need I say more?!

Do you remember I once mentioned how much I despise coconut?  Well, normally I do or should I say, ‘I once did’ because toasted coconut tastes way better than straight out from the bag.

Toasting gives it a slight crunch, a little bite to the soft cake.  And if you’ve ever had shredded coconut straight from the bag then, you know how sweet it can be (a turn off for me).  However toasting it for 5 minutes  at 350°F can change everything.  From a bland white color, a mushy mouth feel and super sweet flavor to a gorgeous light tan, crisp and mellowed sweetness – all the better.

This cake is definitely worth a shot (of rum-LOL).  ENJOY!

  1. Hi Connie
    Is this cake freezable? If not, how long will the sponge last before serving- hoping a couple of days?

    • Hi Esther, I have not frozen this cake myself but I can’t imagine it cannot be. It may however, change the texture once thawed since this cake does hold much liquid. If not frozen, this cake can be chilled for up to 3-5 days for best results.

  2. Thank U the Wonderful cake recipes.. i want to know if is not an inconvenience.. im Not good at all whn the recipes are by Grams..I need to knw in a Cup what is 125 grm of melted butter,200 gram of condensed milk, 350 gr of constarch of flour, or if you have a chart with grams that u can post to have an idea about Grams & Cups measurement would apreaciate that & Thank you fr U help!

    • Hi R. Hernandez, I came across this site that might help you: Please note there may be a difference between liquid measurements versus dry measurements. In most cases, if you cannot use cups to measure the liquid ingredients, you can use ounces. If you need further assistance, you can Google search: “google measurement converter” and in there you can easily convert units. Hope this helps!

  3. Hello
    I stumble upon this recipe while searching for stuff to do with Malibu Rum.
    I’ve used a round pan instead.
    Turn up pretty good.
    I’m gonna serve it tonight for New years eve.
    Thanks for the recipe.


  4. I made this recipe and I spooned the liquid over the cake and made sure it was going into the holes. I also poked more holes when the original holes filled up. It took longer but I didn’t have a bottom full of liquid. it was delicious.

  5. Hi there! Sorry this happened to you. I felt that the original quantity of the liquid (filling) portion of the recipe was a little much as well, so the amount shown here has already been decreased. If you’re using boxed cake mix (which tends to be more moist than most scratch versions), I would recommend to halve the liquid portion to prevent an overly soaked cake. Keep in mind, this cake is intended to remain wet but not fall apart when cut.
    Extra precautionary measures:
    1) As you evenly pour the liquid across the cake, check the sides and stop pouring once you see the liquid begin to rise about 1/8th to 1/4th up the sides of the pan.
    2) Make sure the cake is still hot when you pour the liquid. If the cake is too cool, it will not absorb the liquid filling correctly and may settle straight to the bottom.
    3) Lastly, allow at minimum 3 hours to cool in fridge for proper soaking.
    I hope you’re able to try this again. I feel strongly cutting the liquid portion in half should do the trick. Let me know how this works. :-)

    • Thank you for the reply back. Oh we will try this again, and I am sure once I cut the liquid in half it will work just fine. It is a very delicious cake and I really enjoyed making it and eating it. I posted it on my blog and put a link to where I got the recipe from. Thanks again.

  6. I found your recipe on Pintrest and I have been wanting to try it. So I made it yesterday, it was very moist and yummy but, the part that you pour over the cake seems to have settled to the bottom and the cake is swimming in it and it falls apart when eating it any tips on how to prevent this or things to do differently? It is very tasty just did not hold up Love the frosting. I plan on put it on my blog but, before I do I am asking for some tips to prevent this. Thanks again.

    • I am in the process of making it and I just poured the mixture over the cake and was thinking the same thing, it looks as though my cake is submerged in the liquid mixture, it is chilling now in the ice box and I pray it turns out good!!

      • Hi Shannon! Glad to hear you’re making it. Is an ice box the refrigerator or freezer? Make sure the warm cake is placed in the refrigerator for at least 3 hours. I realize there have been concerns with this recipe. The ratio of the 3 milks from the original Betty Crocker recipe is 1:1:1 however, I reduced that amount to make it less “wet.” Once the cake is ready, the cake should have absorbed majority of the liquid. Keep in mind, this type of cake is supposed to be very moist so you will see a bit of liquid on the bottom of the pan when cut.
        Would you be so kind as to leaving a comment here on how it turned out?

  7. I love your blog and your recipes. I just made canneles de bordeaux with the same rum I am so excited to have the cake recipe! Thanks for sharing!

    • Thank you Bea! Canneles de Bordeaux sounds interesting. I’ve never made it and now I’m intrigued to try it!
      As for my chocolate-rum cake, I’m sure you’ll like it especially if you love Malibu! Let me know how it goes. PS: there a “vanilla” version called Tres Leches Cake I just posted that you may like as well. It has a bit of rum too :)

  8. I was just talking with friends about rum cakes! this looks great! and I agree, cake from a box is fantastic and I do not judge anyone for using it! It’s such a great shortcut!

  9. There’s nothing better than the numbing qualities of booze. And girl, I’d never badmouth cake mix. I grew up eating this stuff. My favourite brownies are still the Duncan Hines version. I’ve never been able to bake a batch with that same texture and chewiness. Your cake looks amazing and sounds absolutely delicious.
