Instructions:
- Preheat oven to 350°F (175°C). Grease and flour cake pans, then line the bottoms with parchment paper rounds.
- Combine sugar and water in a saucepan. Cook over medium heat, without stirring, until amber in color. Carefully whisk in warmed cream, butter, and salt. Remove from heat and let cool slightly.
- In a large bowl, cream together butter and sugar until light and fluffy.
- Beat in eggs one at a time, then stir in vanilla extract.
- In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
- Gradually add dry ingredients to wet ingredients, alternating with buttermilk, beginning and ending with dry ingredients. Mix until just combined.
- Gently fold in the 1/2 cup of caramel sauce to the batter.
- Divide batter evenly between prepared cake pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
- Let cakes cool in pans for 10 minutes before inverting onto a wire rack to cool completely.
- In a large bowl, beat butter until light and fluffy. Gradually add powdered sugar, alternating with heavy cream, until smooth. Stir in the 1/2 cup of caramel sauce, vanilla extract, and salt.
- Level the cake layers if necessary. Place one layer on a serving plate, spread with a generous layer of frosting. Top with the second layer and frost the entire cake.
- Chill the frosted cake for at least 30 minutes before serving.
