Perfect for National Rum Day
August 16th is National Rum Day. Right about now you are probably thinking, “What‘s this got to do with chocolate?”

Well, actually, there is rum in Kahlua!! So, it totally counts!
Kahlua is a sweet, coffee-flavored liqueur that hints at dark chocolate, at least to me. The drink that always come to mind for me is Kahlua and cream. If you think about it (after a couple of these) it’s just an adult glass of chocolate milk, right?
Start with a box mix and add to it
Coffee is a popular additive to baked goods to enhance chocolate flavor, so this Kahlua chocolate cake (found at flourarrangements.org) seemed like a heavenly combination to me, especially since it starts with a box mix and only needs eggs, oil, sour cream and Kahlua to complete the ingredient list.
(Note: The original recipe called for 1½ cups chocolate chips, which I omitted. Please proceed according to your own taste).
This frosting is a keeper!
The other decision was, of course, the frosting. The original recipe called for a chocolate ganache, which looks great in photos, but the last time I used ganache the carnivore in the house felt there wasn’t enough frosting.
I have been on a quest to find the perfect chocolate frosting and this time I stumbled across a keeper: Chocolate-Kahlua frosting. (found at glorioustreats.com) In addition to the usual ingredients in frosting (butter, powdered sugar, more butter, more sugar) this one includes cream cheese, cocoa powder and Kahlua. Yum!
How to make Kahlua Chocolate Cake
The directions for this cake are very straightforward: Put all the ingredients in a bowl and mix for 3 to 5 minutes. Pour into a prepared Bundt pan (greased and dusted with cocoa) and bake for 55 to 60 minutes. Let cool in the pan for 30 minutes and then invert to finish cooling.
How to make Chocolate Kahlua Frosting
The frosting is similarly simple: With a mixer, cream the butter, add cream cheese and mix well. Add the cocoa powder, and then powdered sugar about one cup at a time. Mix well before adding the next cup. Once the powders are fully incorporated, add vanilla, Kahlua and a little heavy cream or milk.

Mmm…
Like many recipes these days, the directions specify the use of a stand mixer. Even though I do have one, I did not use it and instead used my trusty hand-held mixer for both the cake and the frosting. Wasn’t a problem. 🤓
Because of the cream cheese in this frosting, I recommend refrigerating the cake once it’s frosted. I did so, and it was delightful for several days after baking. All I did was loosely wrap the plate with plastic wrap to prevent drying out. The cake stayed moist and flavorful.

And I realized that it’s really quite yummy to eat cold cake, especially in the summer!
