🍰 Salted Caramel Kentucky Butter Cake
🧾 Ingredients
For the cake:
- 3 cups all-purpose flour
- 2 cups granulated sugar
- 1 tsp salt
- 1 tsp baking powder
- ½ tsp baking soda
- 1 cup buttermilk (room temp)
- 1 cup unsalted butter (softened)
- 4 large eggs
- 2 tsp vanilla extract
For the butter sauce (soak):
- ¾ cup sugar
- ⅓ cup butter

- 2 tsp vanilla extract
For the salted caramel glaze:
- 1 cup sugar
- 6 tbsp butter (cubed)
- ½ cup heavy cream
- 1 tsp sea salt (adjust to taste)
👩🍳 Instructions
1. Make the cake
- Preheat oven to 325°F (160°C). Grease and flour a bundt pan.
- Mix flour, sugar, salt, baking powder, and baking soda.
- Add buttermilk, butter, eggs, and vanilla. Beat until smooth (about 3 minutes).
- Pour into pan and bake 60–70 minutes, until a toothpick comes out clean.
2. Prepare the butter soak
- In a saucepan, combine sugar, butter, and water.
- Heat until butter melts and sugar dissolves—don’t boil.
- Remove from heat and stir in vanilla.
3. Soak the cake
- While the cake is still warm (in the pan), poke holes all over.
- Slowly pour the butter sauce over it.
- Let it absorb and cool completely before removing.
4. Make salted caramel glaze
- Melt sugar in a saucepan over medium heat until amber.
- Add butter carefully (it will bubble), stir until melted.
- Slowly add cream, stirring constantly.
- Remove from heat and stir in sea salt.
5. Finish
- Drizzle caramel over the cooled cake.
- Optional: sprinkle a little extra flaky salt on top.
🔥 Tips
- The flavor actually improves the next day—this cake gets more moist over time.
- Use a good-quality vanilla extract; it really shows.
- Don’t rush the caramel—burnt sugar turns bitter fast.
