Ingredients:
- 2 1/2 cups (300g) all-purpose flour, spooned and leveled
- 1 teaspoon (5g) baking powder
- 1/2 teaspoon (2.5g) baking soda
- 1/4 teaspoon (1.25g) salt
- 1 cup (227g) unsalted butter, softened
- 1 3/4 cups (350g) granulated sugar
- 2 large eggs
- 1 teaspoon (5ml) vanilla extract
- 1 cup (240ml) buttermilk
- 1 cup (200g) granulated sugar
- 1/4 cup (60ml) water
- 1/2 cup (120ml) heavy cream, warmed
- 4 tablespoons (57g) unsalted butter, cut into pieces
- 1/2 teaspoon (2.5g) sea salt
- 1 cup (227g) unsalted butter, softened
- 4 cups (480g) powdered sugar, sifted
- 1/2 cup (120ml) Caramel Sauce (recipe above)
- 2 tablespoons (30ml) heavy cream
- 1/2 teaspoon (2.5ml) vanilla extract
- Pinch of sea salt
Instructions:
- Grease and flour two 9-inch round cake pans. Line the bottoms with parchment paper rounds.
- In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
- 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.
- Gradually add dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with dry ingredients. Mix until just combined. Do not overmix.
- Divide batter evenly between prepared cake pans. Bake in a preheated oven (350°F/175°C) 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 them onto a wire rack to cool completely.
- In a medium saucepan, combine sugar and water over medium heat. Cook, without stirring (swirl the pan gently if needed), until the sugar dissolves and turns an amber color.
- Carefully pour in warm heavy cream. The mixture will bubble vigorously. Whisk in butter until melted and smooth.
- Stir in sea salt. Remove from heat and let cool slightly.
- In a large bowl, beat butter until light and fluffy.
- Gradually add powdered sugar, beating until combined. Beat in caramel sauce, heavy cream, vanilla extract, and salt.
- Place one cake layer on a serving plate. Spread with a generous layer of caramel frosting.
- Top with the second cake layer. Frost the entire cake with the remaining caramel frosting.
- Drizzle with additional caramel sauce (optional) and sprinkle with a pinch of sea salt. Slice and serve.
