Creating a delicious Caramel Cake is straightforward. Follow these simple steps to create a stunning dessert:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
3. Combine Wet Ingredients: In another bowl, mix the buttermilk, butter, eggs, and vanilla extract until well blended.
4. Combine Mixtures: Gradually add the wet ingredients to the dry mixture, stirring until the batter is smooth.
5. Add Caramel: Fold in 1 cup of caramel sauce into the cake batter carefully.
6. Divide Batter: Pour the batter evenly into the prepared cake pans.
7. Bake: Place in the preheated oven and bake for 30-35 minutes or until a toothpick inserted comes out clean.
8. Cool Cakes: Once baked, allow the cakes to cool in the pans for about 10 minutes. Then, transfer them to wire racks to cool completely.
9. Prepare Glaze: While the cakes cool, heat 1 ½ cups of caramel sauce in a saucepan until warm and slightly thickened.
10. Assemble: Place one cake layer on a serving plate. Generously drizzle or spread caramel glaze over the layer.
11. Layer the Second Cake: Place the second layer on top and repeat the process of adding caramel glaze.
12. Finish Up: Drizzle any remaining caramel sauce on top and sprinkle with sea salt if desired for a touch of sophistication.
