Anytime I get a chance to add some liquor to my desserts, I jump on it! I love the extra flavor that it adds to the final product. Just because there's rum in the cake doesn't mean you have to get drunk; it means you are about to have a very moist cake with some mind-blowing flavors!

What is Butter Rum Cake?

I think the first time I had rum cake was as a kid. All I can remember from that piece that I sunk was the sweet zang (rum) that the cake had; it reminded me of the pound cakes my dad would bake, just with something a little extra added to it that I never had before.

I remember acting drunk once I found out it had rum in it. Don't judge me.

Anyway, we have Jamaica to thank for the blessing of rum cake and the Southerners to thank for perfecting butter pound cakes. This recipe combines both to make one of the best butter rum pound cake recipes you'll enjoy.

Rum cake has been around for centuries. It's usually made with dark, spiced, coconut, or white rum, and you can add pecans, fruits, and warm spices like cinnamon or nutmeg. You can serve it warm or cold and enjoy its rich and moist texture.

In some parts of the world, it's known as black cake or Christmas pudding. No matter what you call it, one thing is certain: Rum cakes make an excellent addition to any special occasion! Whether you're celebrating a birthday or anniversary, hosting a dinner party, or just want something sweet after dinner—rum cakes are always sure to please your palate.

Let's jump into how to make one.

Butter Rum Cake Ingredients

Here are the ingredients for this delicious and easy classic butter rum cake recipe.

Butter

I love using good European butter for this cake because the higher fat content makes for some of the most amazing butter pound cakes you'll ever try. So splurge and treat yourself.

Sugar

I love using Imperial Sugar granulated sugar when baking. The product has stayed consistent for the last 100 years and is Non-GMO, which lets me know the quality is there from the soil to my home.

All Purpose Flour

I only use unbleached flour for baking. This rum cake recipe will also need baking soda and baking powder.

Eggs

Brown eggs have deep golden yolks, which will make your cake stand out from the rest.

Sour Cream

A little sour cream will add moisture to the cake.

Cinnamon

A little pinch of cinnamon goes a long way but also compliments the warm spices in spiced rum.

Dark Rum

Captain Morgan is my go-to spiced rum, but I used Kraken black spice rum in this recipe and was impressed.

How to Make Rum Cake Recipe

I want you to have fun when you make this cake. It's not as hard as you think, especially if you follow these instructions. You'll reproduce a cake that will have your family begging for more.

Rum Cake: 

The first thing you want to do is take out your butter and eggs about 30 minutes before you plan on baking. Room-temperature ingredients combine better. However, don't worry; I'll teach you a trick to speed that up if you forget.

Preheat your oven to 300°F. In a large mixing bowl, cream butter and sugar until smooth. It takes about 5 minutes, and it's done correctly when you can spread it like icing.

Add eggs one at a time, then sour cream and vanilla. 

Combine the flour, baking powder, baking soda, kosher salt, and cinnamon in a medium bowl.

Add flour to cake batter 1 cup at a time. Mix it on low to ensure the flour doesn't fly everywhere and not overwork the flour. The more you mix it, the tougher your cake will be, even if it's soaked in rum. 

Pour batter into a greased bundt pan, place in the center rack, and bake for 1 hour and 25 minutes until a toothpick inserted into the center comes out clean when removed.

Remove the cake from the oven, invert it, and flip it out on a cake stand or plate. Cool for 1 hour.

Rum Glaze:

Heat a small pot over medium heat. Add butter, ¼ cups of rum, and sugar. Bring to a boil, reduce heat to low, and simmer for 5 minutes. Stir in the remaining rum.

Poke holes in the cake with a wooden skewer or steak knife. In two batches, pour ½ cups of the butter rum glaze over the cake, allowing it to absorb more of the glaze. Then, brush or spoon the rest of the glaze over the cake.

Icing:

Add powdered sugar, rum, butter, and milk in a large bowl and mix until smooth. Pour icing evenly over. Serve and enjoy with some homemade sweet potato ice cream!

Storing Rum Cake

Butter rum cake is best three days after it's made but will remain fresh for about four days if covered on the counter in a cool place. Slices can stay fresher longer by being placed in an airtight container in the fridge for seven days.
 
Freeze the cake in a freezer-safe container for up to 3 months. Thaw for 1-2 hours before eating. Reheat the cake in a 300°F oven for 5 minutes or pop it in the microwave for 10 seconds.

Pro Recipe Substitutions, Tips & Tricks

Here are the best practices, techniques, substitutes, and flavor builders you'll need.

• Warming the cake in the oven for about 5 minutes the next day will help the cake release from the pan. 
• I used a dark-finish bundt pan, so I baked it at 300°F; if your pan has a lighter finish, bake it at 325°F.
• If you forget to remove your butter, slice it into half-ton portions and leave them in a single layer on the butter paper. Then, measure out your ingredients. It should be at room temperature in 5-10 minutes (depending on your home's temperature).
• If you forget to take your eggs out, crack them into a bowl and proceed to prep ingredients or cover them with warm tap water for 5 minutes to knock the chill off.
• One major key is to cream your butter and sugar properly. Creaming for 3-5 minutes allows enough air to be incorporated into the cakes. Time will vary depending on whether you use a stand mixer or a hand mixer. 
• Feel free to use 8 oz. cream cheese or 1 cup of whole milk instead of sour cream.
• For a richer flavor, swap out the white sugar for brown sugar.
• You can use gluten-free flour instead of all-purpose flour to make this cake gluten-friendly.
• Feel free to use self-rising flour instead of all-purpose flour. Self-rising flour already contains salt and leavening ingredients.
• If you use salted butter instead of unsalted butter, omit the salt from the recipe.
• You can make a rum sauce by melting one stick of butter and combining it with the rum before pouring the rum syrup over the cake.
• Feel free to add chopped pecans to your cake batter before baking. If you use pecans, toast them slightly before sprinkling them into the cake.
• Add ¼ - ½ teaspoon of nutmeg to your cake.
• If you do not consume alcohol, use a rum extract instead of vanilla extract in the cake for the same great taste.
