These are the basic steps for making rum soaked cake. Refer to the full, printable recipe card below for detailed instructions.

Mixing the cake batter.

Step 1: Prep

First, preheat oven to 325 degrees. Grease and flour a 10 inch tube or Bundt pan.  Sprinkle nuts over bottom of pan.

Step 2: Cake Batter

In a large bowl, combine cake mix, pudding and other cake ingredients with an electric mixer. Beat for 4 minutes. Pour into prepared pan over nuts.

Step 3: Bake the Cake

Bake at 325 degrees for 50-60 minutes, or until a cake tester or toothpick comes out clean. Once it is ready, remove cake from the oven.

Cooling the finished cake.

Step 4: Make the Syrup

Once cake has finished baking, make the rum sauce. Combine butter and sugar in a saucepan and bring to a boil over medium heat. Next, remove from heat and add water and rum. Pour hot rum glaze over your cake as soon as it’s removed from the oven, including the sides of the cake.

Step 5: Turn Out this Best Rum Cake

Finally, allow the cake to sit in pan for 30 minutes so it can come out clean. Carefully remove and invert the cake onto a plate. Allow to cool completely. For more flavor brush the remaining glaze for a moist cake.

Recipe FAQs to Make the Rum Cake

Try not to use butter. It has a tendency to stick into the cracks in your Bundt pan. Spray well with a nonstick cooking spray, then coat the pan with a liberal amount of flour mixture so the cake comes out clean. Make sure to tap the top and sides of the pan to loosen the cake, then carefully invert to remove the cake.

Use what you have, or what you enjoy. A Bacardi rum cake is especially recommended. The cake is amazing.

For a healthier cake, use a gluten-free yellow cake mix in this rum cake recipe.

  • Variation tip: Feel free to add different nuts for the top of the cake. Use your favorite or omit if someone has an allergy.
  • Alternate ingredient: Dried cranberries or raisins to taste can be great for this holiday cake.
  • Vanilla Extract: Do not like rum? Simply add a good-quality vanilla extract.

  1. Thank you for this recipe. I tried it today. I usually always put a little bit of my own twist on things — to make it personalized. I did swap out eggnog for the water in the cake ingredients, and added some fresh ground nutmeg and vanilla. Other than that, I followed your recipe. The cake is fabulous. 5 stars — a keeper — will make frequently. Debra

  2. I stumbled upon your website through Tasty Kitchen, and I just realized that this recipe of yours is nearly *identical* to the BEST rum cake I have ever had, from when I went sailing in St. Thomas a few years back. I have been meaning to make this cake…and you just reminded me to get on it already =) So, thank you! And to all of you contemplating making this cake…DO IT. You won’t regret it!

  3. Christina, your story made me chuckle! My question is, since the cake is still in the pan when you pour the glaze over it, are you actually pouring the gaze on the bottom of the cake? It sounds delicious, I can’t wait to try it!

    • Glad it made you smile! ๐Ÿ™‚ Yes, you pour the glaze over the “bottom” of the cake. It takes a bit for it all to soak in. Enjoy! ๐Ÿ™‚
