Easiest Rum Cake Recipe Ever: This Boozy Vanilla Cake Is Unforgettable

Needing another dessert for Christmas last year, my friend shared her easy rum cake recipe with me. Thank you, friend! This is the easiest rum cake to prepare, smells heavenly and is moist and full of vanilla, butter and rum flavor. Now it's made year-round and not just at the holidays. 

The moist rum cake is made with a box of yellow cake mix, a box of instant vanilla pudding, eggs, vegetable oil, water and rum. While the cake bakes, make the glaze with a stick of butter, granulated sugar, water and rum. When the cake comes out of the oven, poke holes all over it and pour the glaze on so it seeps down into the cake. Let the cake cool before serving.

This delicious rum cake dessert recipe will be a new family tradition, for the holidays and beyond. I don't even associate it with the holidays anymore because I've made it so much. It adds a tropical feel to the cooler months and a festive feel to summer gatherings. 

Cuisine: American
Prep Time: 10 minutes
Cook Time: 50 to 60 minutes

Total Time: 1 hour (approximately) 
Servings: Makes 1 cake



  • 1 box (16 ounces) yellow cake mix (I used Duncan Hines Butter Golden)
  • 1 box (3.4 ounces) instant vanilla pudding mix
  • 4 eggs
  • 1/2 cup vegetable oil
  • 1/2 cup water
  • 1/2 cup white rum or spiced rum (I used spiced rum)


  • 1 stick (8 tablespoons) butter
  • 1 cup granulated sugar
  • 1/4 cup water
  • 1/2 cup white rum or spiced rum 

Here's how to make it: 

  1. With an electric mixer, combine the cake mix, pudding mix, eggs, oil, water and rum. Beat well.
  2. Pour into a greased and floured bundt pan (one that holds at least 10 cups). Bake in a preheated 325-degree F oven for about 50 to 60 minutes or until a toothpick comes out clean.
  3. While the cake bakes, combine the butter, sugar and water in a saucepot. Bring to a boil, stirring, until everything is melted together and combined. Turn off the heat and stir in the rum.
  4. When the cake comes out of the oven, pour the glaze over it while it is still in the pan (my friend likes to poke holes in it first).
  5. Let the cake cool, then unmold onto a serving platter.

One that holds at least 10 cups. I use my standard size bundt pan for a regular-size cake.

I've always wanted to make a rum cake, an old tradition in my husband's family. Thank you for a recipe that is doable!
Donna John
Yes! It is so doable. I made this for Christmas and it was a huge hit. Now a tradition. Going to make it again soon. Let us know how your husband likes it! Patti Favetti
Susan Evind
This looks fabulous, Donna! I like Bundt cakes without extra icing all over, so just a bit of sprinkled powdered sugar is ok?
Donna John
Yes! Powdered sugar would be good. I'm the same way. I go for the cakes without frosting. Sweet and simple. Next time going to try a chocolate rum cake.
