Best Salted Caramel Kentucky Butter Cake Recipe
You are gonna LOVE this caramel pound cake! It starts with an incredibly moist sour cream pound cake with butter and rum extracts for a rich, decadent flavor. And now for the best part! While the cake bakes, we'll whip up a from-scratch salted caramel butter sauce that we'll infuse into the warm cake right after it comes out of the oven.
Then, we'll cook down our remaining syrup into a delectable homemade caramel sauce to pour over the top! All it'll need then is some flaky sea salt to bring out those rich caramel flavors!
This caramel pound cake is perfect with a morning cup of coffee (or cardamom latte) or as the finishing touch for cozy family dinners. It's one of my favorite pound cakes, and you're sure to get rave reviews whenever you make it!

What is Kentucky butter cake made of?
This delicious cake is made from scratch with simple ingredients, so you may have many of them on hand already! You can see the full recipe and ingredient measurements in the recipe card below, but here's what you'll need:
- butter - I generally prefer salted butter in my cakes, but if you have unsalted butter, that's fine! Just mix ¾ teaspoon of salt in with your flour. This recipe uses lots of butter, so if possible, use a high-quality butter like Kerrygold. Make sure your butter is softened to room temperature before adding it in. If your kitchen is excessively hot or cool, you may want to check the temperature of your butter with an instant-read thermometer. It should be around 70 degrees Fahrenheit.
- sugar - we'll use granulated sugar to cream with our butter and create that perfect fluffy texture!
- eggs - be sure to use room temperature large eggs. They should not be cold to the touch. To save time, you can submerge your eggs in lukewarm water for 15 minutes.
- vanilla - for the best flavor, I like to use pure vanilla extract. Or you can make your own!
- butter and rum extracts - these are optional, but they add so much rich flavor to this cake! These flavors are what make this such a unique recipe. I use McCormick Butter Extract and Rum Extract. And for more rum flavor, check out my rum espresso martini recipe and my Eggnog Pound Cake!
- flour - I like to use Swans' Down cake flour in this caramel pound cake recipe for a soft, tender crumb, but you can also use all purpose flour if you like! For all-purpose flour, I prefer White Lily. Be sure to measure your flour by weight with a kitchen scale to make sure you don't accidentally add too much.
- baking soda - to help create a little bit more lift!
- sour cream - like your other ingredients, your sour cream should be completely room temperature before you begin. Use a full-fat sour cream for perfectly moist texture, like in my Blueberry and Lemon Pound Cake.
- cake release - I usually use baking spray with no problems, but I've recently started to prefer "cake goop": equal parts shortening, flour, and vegetable oil. Mix them with an electric mixer and use a pastry brush to brush a thin later of the goop onto your cake pan. Your cake will come right out!
You may notice there's no baking soda or baking powder in this caramel pound cake recipe -- that's on purpose! Traditional recipes for pound cakes don't use any leavening agents at all, and the way they achieve their rise is from the eggs!
This recipe works the same way, and because we're leaving out the baking powder we achieve a tighter, more buttery crumb! And for more of the best fall goodies, check out my list of the 36 Best Fall Desserts for your Seasonal Celebrations!
Then, here's what you'll need for your salted caramel sauce and salted caramel glaze!
- granulated sugar - white sugar is the main ingredient in our caramel sauce!
- water - to help cook the sugar down and thin the sauce out a bit.
- butter - again, I use salted butter, but if you use unsalted just add an additional ¼ teaspoon of salt.
- evaporated milk - you can also use whole milk.
- vanilla & rum extracts - to add even more flavor to this sauce!
- sea salt - I like to add a pinch of sea salt to the caramel sauce as well as on top of the finished cake!
See recipe card for quantities.
Equipment
I recommend making this salted caramel Kentucky butter cake in a high-quality Bundt or tube cake pan. I like the Elegant Party Bundt Pan from Nordic Ware. To mix this salted caramel cake recipe, I use my KitchenAid stand mixer, but you can also use a hand mixer if you don't have a stand mixer.
I also recommend a rubber spatula for folding in the dry ingredients and scraping the sides of the bowl. You may also want to have a wire rack to help the cake cool more quickly and allow for your glaze to drip off the sides cleanly.
Instructions
You can check below for a full salted caramel Kentucky butter cake video and recipe instructions, but here are the basic steps to make this cake:
Cream butter and sugar until light and fluffy.
Add eggs one at a time, mixing until incorporated between each.
Add extracts and mix until combined.
Alternate adding flour and sour cream to the wet ingredients, folding each addition in until just barely combined.
Fold batter together just until flour streaks disappear.
Pour batter in prepared bundt pan and tap firmly on the counter to eliminate air bubbles. Bake until a toothpick entered into the cake comes out clean.
Poke holes in the top of the cake and drizzle some of the caramel syrup over them. Let cake cool for an hour, then flip out onto a wire rack.
Reduce remaining caramel into a thicker glaze and let cool. Pour over cooled cake.
Hint: This caramel pound cake is even better the next day! Let it sit overnight, covered in a cake dome or another airtight container, and store the glaze in the fridge. Then glaze it and serve the following day for the best rich, buttery texture.

Is baking soda used in this recipe? Your comments contradict the recipe. Please clarify. Thanks.
Chenée Lewis says
Yes, I recently updated the recipe after some additional testing, so it does call for baking soda. Thanks for checking! 🙂
Rosemary Kelley says
Can you use buttermilk instead of yogurt
Chenée Lewis says
I think you mean instead of the sour cream, and yes you can! I would go for full-fat buttermilk, room temperature.
Mindy Rice says
this is incredible! How can I make them into buntlets?
Chenée Lewis says
I haven't tried making this recipe into bundtlets so I can't say for sure, but you could try checking the mini bundts for doneness after 20 minutes. Otherwise the recipe should be the same 🙂
