How to Make Kentucky Butter Cake
Visual leaner? Watch this cake get made from start to finish!
It’s that time again, people! Pound cake time!! It’s been a while since I’ve posted a pound cake recipe, right? Today we are making Kentucky Butter Cake, and baaaaby….. whoever invented this cake plays entirely too much!! It’s so simple yet so good and addictive!
My husband and I decided to do a high protein veggie diet this week. I made cake in advance for us to eat on our cheat day this weekend. Ummmm yeah…about that. We crashed and burned.
We devoured that poor cake the day it came out of the oven. I should have known better, but I thought I had stronger willpower than that. My husband suggested that we finish the cake off so that it won’t tempt us all week. Gosh, he has the best solutions, I tell ya!
I’m so tempted to say Kentucky Butter Cake is my new favorite, but we all know how that goes. But man, this cake is incredible.
What is Kentucky Butter Cake?
Kentucky Butter Cake starts with a super whipped batter pound cake batter. It has notes of vanilla and Rum. After it’s baked, holes are poked into and then drenched in vanilla rum-flavored buttery syrup. Yeah, this cake is taking no prisoners! It’s coming for all waistlines and man, is it worth it!!
Why is it called Kentucky Butter Cake?
If you’re wondering how this cake got its name, then that makes two of us. Seriously, I’ve been researching like crazy, and even on google, I can’t find an authentic story of how this cake came about. I came across a story about it being a Pillsbury bake-off winner and then another story that debunked that one. My guess is that the cake was made in Kentucky, and since it has lots of butter and a butter sauce, it’s called a Kentucky Butter Cake. Boom! No, but seriously, if you find the real story behind this cake, do share!
Kentucky Butter Cake With Rum or Brandy?
For me, Rum wins hands down! My preference is a bit of rum extract. It just gives the cake a nice hint of warm rum flavor that goes so great with the butter vanilla flavor. Some people opt to replace the water in the recipe with Rum for an even deeper rum flavor or brandy or brandy extract.
Kentucky butter cake is known for being super moist and tender, thanks to all that buttery syrup that oozes between the crumbs. It’s the perfect cake for shipping since it stays moist for so long.
Serve this cake the next day!
It’s true! To me, all pound cakes taste better the next day, but Kentucky Butter Cake is on a whole different level of fantastic the next day! The Rum has settled into this balanced flavor, and the buttery syrup has absorbed and is no longer wet. It’s pure perfection!! Definitely worth the wait!!

Ingredients
CAKE
- 3 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 16 tablespoons unsalted butter (2 sticks), room temperature
- 1/2 cup butter-flavored shortening
- 3 cups granulated sugar
- 5 eggs, room temperature
- 2 teaspoons vanilla extract
- 1/4 teaspoon rum extract
- 1 cup buttermilk
BUTTER SYRUP
- 12 tablespoons unsalted butter (1 ½ sticks)
- 1½ cups granulated sugar
- 1/3 cup water
- 1 teaspoon vanilla extract
- 1/2 teaspoon rum extract
Instructions
- Preheat oven to 325 F. Grease and flour a bundt pan. Set aside.
- In a large bowl whisk together flour, baking powder and salt. Set aside.
- In a large bowl cream together butter and shortening on low speed, until combined.
- Alternate adding the eggs and sugar, mixing after each addition, just until combined, until batter is fluffy.
- Mix in vanilla extract and rum extract.
- Mix the dry ingredients into the wet ingredients, alternating with the buttermilk until the batter is combined and fluffy.
- Spoon batter into prepared pan and give the pan a few shakes to release any air bubbles and level the surface.
- Bake for 1 hour and 15-20 minutes on the middle rack until cake tester inserted into the cake comes out clean or with moist crumbs clinging to it.
- Remove cake from oven and poke holes into the cake, being careful not to poke holes all the way through to the top. Set aside
- To make the syrup, melt butter in a sauce pan over medium low heat. Add the sugar and water and stir until sugar has dissolved.
- Keep stirring until butter mixture becomes foamy and thickens to the texture of a loose syrup (do not boil). Remove from heat. Add in vanilla and rum extract.
- Spoon the butter mixture over that cake so that is goes down in the holes. (Reserve about 1/4-1/2 cup of the mixture for brushing the outside of the cake.)
- Let sit for about 10 minutes or until the syrup is no longer sticky. (Don't let it sit for too long or the cake will become stuck in the pan)
- Carefully remove cake from cake pan and allow the cake to cool and the syrup to absorb, for about an hour.
- Reheat the leftover syrup and brush it all over the cake.
- Serve. (See tip for serving the next day)
I gave up sweets for Lent. Guess what I’m baking for Easter!!
I am so excited to make this Kentucky Butter Cake. Thank you for posting this recipe.
Can’t wait to try this! Would you mind sharing the brand of buttermilk you use? Every time I make a cake recipe with buttermilk it doesn’t turn out right. Thank you!
Make sure you use full fat buttermilk. Low fat kind will not turn out right. The brand I use is Gourmet. It has more than a quart but less than a half gallon in the bottle.
Hi,
While this isn’t my recipe I do plan on making it. I suggest using whole fat buttermilk, also another trick is letting the buttermilk come to room temperature. Set it out ten minutes are so before you start the rest of the steps. Those two things can make a lot of difference when it comes to the quality of the cake .
I also am in Kentucky and you knocked this one out of the park !! Is is fabulous…I have not used buttermilk in it before and I think that is what makes is the best I have ever had. Thanks for sharing.
Hi there. Looks great. I’m not a baker… But I was told and held by my Momma to use cake flour. I see this recipe use all purpose flour, can/how do I sub cake flour for the all purpose?
Hi,
While this isn’t my recipe I maybe if some assistance.
For every cup of all purpose flour substitute 1 cup plus 2 tablespoons cake flour for every cup of all-purpose flour
Since this calls for 3 cups of all purpose flour You’ll need 3 cups plus six table spoons of cake flour. Hope this helps!
I grew up in Kentucky, can’t wait to try this!
