What Is Kentucky Butter Cake?
Kentucky Butter Cake is a traditional Southern dessert famous for its dense texture and buttery flavor. What sets it apart from other butter cakes is the warm butter-sugar glaze poured over the cake while it’s still hot. This allows the glaze to soak into the cake, creating an incredibly moist interior with a subtle crust on the outside.
In this version, we enhance the classic recipe by adding homemade salted caramel sauce, giving the cake a deeper flavor profile and a more decadent finish.

How to Make Salted Caramel Kentucky Butter Cake
Prepare the Baking Pan
Preheat your oven to 325°F (165°C). Generously grease your Bundt pan with butter or baking spray, making sure to coat every crevice. Lightly dust with flour and tap out excess.
This step is crucial—Kentucky Butter Cake is rich, and proper greasing ensures a clean release.
Mix the Dry Ingredients
In a medium bowl, whisk together the flour, salt, baking powder, and baking soda. Set aside.
This helps distribute the leavening evenly, ensuring a uniform rise.
Cream the Butter and Sugar
In a large bowl, beat the softened butter and granulated sugar until light and fluffy, about 4–5 minutes. Don’t rush this step—it’s key to a tender crumb.
Add eggs one at a time, beating well after each addition. Stir in the vanilla extract.
Combine Wet and Dry Ingredients
Alternately add the dry ingredients and buttermilk to the butter mixture, beginning and ending with the dry ingredients. Mix on low speed just until combined.
Avoid overmixing, which can make the cake dense instead of tender.
Bake the Cake
Pour the batter evenly into the prepared Bundt pan. Smooth the top and tap gently on the counter to release air bubbles.
Bake for 60–70 minutes, or until a toothpick inserted comes out clean or with a few moist crumbs.
Making the Butter Caramel Glaze
While the cake is baking, prepare the glaze.
In a saucepan over medium heat, combine butter, brown sugar, water, and salt. Stir continuously until the butter melts and the sugar dissolves. Bring to a gentle simmer and cook for 2–3 minutes.
Remove from heat and stir in vanilla extract.
Glazing the Cake
Once the cake is out of the oven, leave it in the pan. Using a skewer or toothpick, poke holes all over the cake.
Slowly pour the warm glaze over the hot cake, allowing it to soak in. Let the cake rest for 20–30 minutes before turning it out onto a serving plate.
This step is what gives Kentucky Butter Cake its legendary moisture.
How to Make Homemade Salted Caramel Sauce

Caramel Sauce Instructions
Heat sugar in a saucepan over medium heat, stirring constantly. Once it melts and turns amber, carefully add butter and whisk until smooth.
Slowly pour in warm cream while whisking (be careful—it will bubble). Remove from heat and stir in salt. Let cool slightly before using.
