Set the oven temperature to 325 degrees Fahrenheit.

In a mixing bowl, blend together the cake ingredients—flour, sugar, eggs, and butter—using an electric mixer until the mixture is smooth and creamy.

Thoroughly grease a bundt pan to prevent sticking. Spread the cake batter evenly into the greased bundt pan. Bake in the preheated oven for 55-65 minutes or until a toothpick comes out clean.

Let the baked cake cool in the bundt pan to allow it to set properly.

In a pot over medium heat, combine the ingredients for the sauce—butter, sugar, and any other flavorings. Stir the mixture until the butter is melted. Heat only until well combined, avoiding overcooking.

While the cake is still in the bundt pan, use a skewer or fork to poke holes evenly throughout the cake. Pour the prepared caramel sauce over the cake, ensuring it seeps into the holes for a rich, buttery infusion.

Let the cake cool with the caramel sauce, allowing it to absorb and enhance the flavor. Once cooled, carefully remove the cake from the bundt pan. Serve and savor the delightful combination of moist cake and decadent caramel sauce. Enjoy your Easiest Salted Caramel Kentucky Butter Cake!
