What is Rum Cake?

Rum cake is a dessert enjoyed in countries all over the world. For each unique name it has, there’s a variety of ways to prepare it.

This recipe is the vegan version of the Bacardi Rum Cake which gained its popularity during the late 70’s. If you’re not familiar with the original old school rum cake, think: a golden bundt cake made with boxed yellow cake mix, pudding mix, eggs, oil, water and rum to create the a dense and tender cake. It’s then brushed or soaked in a butter rum sauce. Being delightfully indulgent and super easy to prepare, it’s no wonder why it’s so loved!

The Classic Rum Cake Goes Vegan

There are some vegan cake and pudding mixes available so veganizing this may have been simpler than the recipe testing I’ve done for this homemade rum cake. I’ve never really gravitated to cake mixes. I have nothing against them, I just find that they tend to be expensive and the dry ingredients for a cake are pretty easy to assemble at home.

That said, I did use custard powder in this vegan rum cake. I really like Bird’s Custard Powder which is naturally egg-free. It gives us that density and tender crumb we’re looking for in a rum cake. The custard powder also gives the cake a nice yellow hue and full flavor.

Some of the classic old school rum cakes include nuts, some of them don’t. I chose not to include them in this recipe but if you would like add nuts, sprinkle 1 cup of chopped walnuts or pecans on the bottom of the prepared bundt pan before adding the batter.

Magic of Silken Tofu in Vegan Rum Cake

Silken tofu is magical in vegan pound cakes. Now before I lose you, you will not be able to taste tofu in this cake! Silken tofu is usually found room temperature in tetra-paks and are different than the tofus you’ll find in the cooler section at the grocery store. True to it’s name, it’s incredibly silky and very mild in flavor, if not verging on being flavorless. This unique type of tofu adds moisture as well as strengthens the body of the cake so it can take on the dreamy rum syrup. We’re after a tender crumb but not so delicate that it will become gluey and disintegrate under the syrup.

The silken tofu absolutely needs to be blended up to make sure you don’t have flecks of it in your cake. If you don’t have a large enough blender for all of the wet ingredients, you can use a bullet style smoothie blender and blend the tofu and milk together. Once the tofu is completely blended and no fine bits remain, then mix this with the rest of the wet ingredients in a large measuring cup or medium sized bowl.

Make Vegan Rum Cake Ahead of Time

This vegan rum cake actually gets better the longer it sits. For the best flavor, I like to make the rum cake and soak it with half of the sauce the day before I plan to serve it. Once it’s completely cool, wrap it or cover it. At serving time, drizzle each piece with a bit of the remaining sauce.

Ingredients

For the Rum Cake:

  • 1 cup plant-based milk
  • 1/2 cup dark rum*
  • 2/3 cup extra-firm silken** tofu***
  • 3/4 cup neutral oil (eg avocado, canola, etc)
  • 3 tbsp apple cider vinegar or white vinegar
  • 1 tbsp vanilla extract
  • 3 cups all-purpose flour
  • 1 3/4 cup granulated sugar
  • 4 tbsp vegan custard powder
  • 2 tsp baking powder
  • 1 tsp baking soda
  • 1 tsp salt

For the Rum Glaze:

  • 1/2 cup vegan butter
  • 1/4 cup water
  • 1 cup granulated sugar
  • 1/2 cup dark rum
  • 1/4 tsp salt

Instructions

For the Rum Cake:

  • Preheat the oven to 350ºF. Prepare a 12-cup bundt pan – wipe down with non-hydrogenated shortening. Do not use vegan butter or margarine. If using cooking spray, do this just before you add the batter so the spray doesn't drip down the pan.
  • Combine the milk, rum, tofu, oil, vinegar, and vanilla in a blender – blend on high until completely smooth scraping down the sides as necessary.
  • In a large bowl, sift the flour, sugar, custard powder, baking powder, baking soda and salt.
  • Make a shallow well, and pour in the wet ingredients into the dry. Mix with a spoon, taking care not to over mix. Pour into the prepared bundt pan and bake in the center of the preheated oven for 50-60 minutes or until a toothpick inserted comes out clean or with a few baked crumbs. Let the cake cool in the pan for 10 minutes then invert onto a cooling rack.

For the Rum Glaze:

  • While the cake cools, prepare the rum glaze. In a small saucepan, combine the vegan butter, water, sugar and salt over medium heat. Bring to a boil, stirring continuously for 5 minutes taking care not to let it boil over. Remove from heat and mix in the rum – be careful, the mixture will bubble vigorously.
  • Wash and dry the bundt pan, place over the cooling cake and invert the cake back into the pan. Pour the half of the hot rum syrup all over the cake, down the sides and let soak for an hour, and finish cooling. If you pour the half of the sauce over it, you can save the rest to drizzle over the slices of cake at serving time. Otherwise, you can pour all of the rum glaze over the cake for soaking, both options are great. The cake is even better then next day.

*dark rum gives this cake the nicest flavor compared with light rum or spiced rum.
**silken tofu is different than the tofus in the cooler section at the store. Silken tofu is usually sold in tetra-paks, blends up like custard and is almost flavorless. Do not use other types of tofu because they have a very different texture which does not blend smoothly.
***if you can’t find silken tofu, may substitute with 1/2 cup applesauce

    1. I use Bird’s Custard Powder which is accidentally vegan. You can find it on Amazon ( https://amzn.to/2Pq6WYJ ), and I have seen in many different grocery stores in the pudding section. If you make the cake, I hope you enjoy it! ~Bronwyn

    1. Hi Nancy! Do you know what the volume of the individual tartlet pan is, and how many cavities there are? Once we know that we can figure out how much we need to reduce the volume of batter and then I can give you an idea of baking time. There’s an automatic serving adjustment in this recipe card, so if (for example), you need to fill a total of 6 cups (which is half of what this recipe makes for a 12 cup bundt pan), you would reduce the serving size down from 16 to 8 (a 12 cup bundt has about 16 servings.) If you send me more info about your pan, I’d be happy to help! ~Bronwyn

  1. you never gave directions about what to do with the 1 1/4 cups of sugar for the cake. I’m making it now for Christmas and hope it doesn’t flop!

    1. Hi Beverley, 1 3/4 cups of granulated sugar is added in with the flour and other dry ingredients. Hope you love the cake, and Merry Christmas! ~Bronwyn

    1. Hi Ashley! The main ingredient in custard powder is cornstarch. I haven’t tested the cake using cornstarch instead of custard powder, but I suspect the flavor may not be as full and the color won’t be as golden. That said, I’m betting it will be delicious! If you try it with cornstarch, I’d love to hear back from you and how it went! ~ Bronwyn

      1. I just wanted to let you know I tried your above suggestion and substituted cornstarch for the custard powder. I additionally added a bit more vanilla to make up for the vanilla in the custard powder and the cake turned out wonderful! Wow, what a treat! Thank you!

      2. Hi Julie! Thanks so much for the update! Good to know that the cornstarch + extra vanilla works well especially if custard powder isn’t in as common in some homes. I’m so happy you enjoyed the cake! 🙂 ~Bronwyn

    1. Hi! No, vegan custard powder is mostly cornstarch with some flavor. Egg substitutes vary in their ingredients – some have cornstarch but many don’t. If you don’t have custard powder, you can use cornstarch instead and increase the vanilla by a tsp or 2. I hope you enjoy the cake! ~Bronwyn

  2. The silken tofu, what brand did you use?The extra firm silken is throwing me off. My husband lovesssss rum cake, since going vegan he has been craving it! Please help, as it is our 10 yr anniversary and I want to surprise him!

    1. Hi there! I used Mori-Nu – you can check it out here: https://amzn.to/3dRmgGv Silken tofu is similar to regular tofu in that there’s varying firmness. The firmer it is, the less water content. That said, don’t use regular tofu in this cake. If you can’t get your hands on silken tofu, you can use about 1/2 cup applesauce instead with similar textural results. I hope you both enjoy the cake! Happy Anniversary! ~Bronwyn

      1. You have made our 10 yr – beach getaway picnic anniversary, a success! I used the 1/2 cup applesauce and the corn starch. It came out so great, I swear I saw tears in his eyes!! Paired it with some fruit, bread and good beer! Thanks again for this perfect 10/10 recipe!!

      2. Aww! Thanks so much for letting me know! I’m so happy that you both enjoyed the cake and that it added so much to your anniversary. You made my day 🙂 Wishing you both much happiness for many years to come! ~Bronwyn

  3. Hello there!
    Thank you for this recipe!
    I am very excited to try to make your Rum Cake however, I am making it for my bother and myself and we are both Gluten intolerant. do you think making it with any of the gluten free flours it will work?

    1. Hi Marlene! Thanks for your interest in this recipe! While I haven’t tested this specific recipe with gluten-free flour, I have had success in making other vegan cakes gluten-free by using an all-purpose gluten-free flour blend which includes xanthan gum in the list of ingredients. If the all purpose gf flour blend you’re using does not, you can add 1.5 tsp of xanthan gum to the dry ingredients. Whisk really well for even distribution. If you do try this recipe, I hope you both enjoy it! Let me know how it goes! ~ Bronwyn
