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!

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. I made this cake and it was absolutely delicious! Would like to serve at a luau party as cupcakes, but don’t want it to be so moist on the bottom. Do you think I could use a smaller amount of the milk/rum mixture?

    1. Hi Kay,
      Glad to hear you liked this cake recipe and making it for a luau party sounds perfect! There is a chance it could get soggy at the bottom of the cupcake liners so yes, you can put less of the milk/rum mixture. I would cut this portion by half. Right before the party, maybe bring extra cupcake liners to double up if it’s soaked through too much. This will give the cupcakes a fresh look on the outside, similar to this Snickerdoodle Cupcakes post where I doubled up on the liners. Have fun at the party!
