For the Cake:
- Preheat your oven to 325°F (163°C). Grease and flour a 10-inch bundt pan.
- In a medium-sized bowl, whisk together the flour, baking powder, baking soda, and salt. Set this dry ingredient mixture aside.
- In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
- Beat in the eggs, one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract.
- Gradually add the dry ingredient mixture to the wet ingredients, alternating with buttermilk. Begin and end with the dry ingredients. Mix until just combined.
- Pour the batter into the prepared bundt pan and smooth the top.
- Bake in the preheated oven for about 50-60 minutes, or until a toothpick inserted into the center comes out clean or with a few crumbs attached.
- Let the cake cool in the pan for about 10 minutes, then invert it onto a serving plate.
For the Salted Caramel Glaze:
- In a saucepan, combine the granulated sugar and water. Cook over medium-high heat, without stirring, until it turns a deep amber color. This usually takes about 10-15 minutes.
- Remove the pan from the heat and carefully add the heavy cream and butter. Be cautious, as the mixture will bubble up.
- Stir in the salt to taste. Start with 1/2 teaspoon and add more if you prefer a saltier flavor.
- Let the caramel cool for a few minutes, then drizzle it over the cooled Kentucky butter cake.
- Allow the cake to sit for the caramel to set before slicing and serving.
Enjoy your salted caramel Kentucky butter cake with a scoop of vanilla ice cream or a dollop of whipped cream for an extra treat.
