Keto Rum Cake

by hungryelephant

A delicious keto rum cake! Soaked in a rum syrup, this is the perfect dessert. Only 1.9 net carbs per slice. Totally worth it.

Traditional Caribbean rum cakes usually add in some rum-soaked fruit, which by the way would be delicious, but for keto it would most likely be very high in carbs. So instead, I am making this similar to a ‘butter cake’ that is soaked in a delicious rum syrup (sugar free of course).

For this delightful dessert, I based it off my keto Kentucky butter cake recipe. It’s super easy and one of my most popular cakes. Instead of adding a ton of sour cream,  I swapped some of it out to add in the rum! Simple!

I also added in a tablespoon of whey isolate, however this is totally optional. I just like that it helps the cake rise just a little bit better than without it.

As for the rum – you can use any kind but as I’m typing this, I feel like mentioning spiced rum might taste amazing. If anyone uses spiced rum, leave a comment below to let me know how it tastes!

I made this rum cake today. My husband loved it,, but i like my cakes more moist. I’m new to Keto anything. Is it supposed to be more dry than moist? If, so what did I do wrong or what can I add to make it more moist?

Hi! sorry for the late reply. You could always add some extra butter or sour cream to the mix – those will usually make a more moist cake! hope that helps!

This cake is amazing, I have made it twice now and both times it’s been delicious. Can’t believe it’s Keto! I’ve noticed you have some other versions of the cake, could you use this as a base for a chocolate cake?
