(Serves 10–12)
For the cake:
2 1/2 cups (315 g) all-purpose flour
2 1/2 teaspoons baking powder
1/2 teaspoon salt
1 cup (225 g) unsalted butter, softened
1 3/4 cups (350 g) granulated sugar
4 large eggs
1 tablespoon vanilla extract
1 cup (240 ml) buttermilk (room temperature)
For the salted caramel sauce:
1 cup (200 g) granulated sugar
6 tablespoons (85 g) unsalted butter, cut into cubes
1/2 cup (120 ml) heavy cream (warm)
1 teaspoon flaky sea salt (plus extra for topping!)
For the caramel buttercream:
1 cup (225 g) unsalted butter, softened
2 1/2 cups (300 g) powdered sugar, sifted
1/2 cup salted caramel sauce (from above)
Preheat oven to 350°F (175°C).
Grease and line two 8-inch (20 cm) round cake pans with parchment paper.
In a bowl, whisk together flour, baking powder, and salt.
In a large bowl, cream butter and sugar together until light and fluffy (about 3–5 minutes).
Beat in the eggs one at a time, then add vanilla.
Add the flour mixture in 3 parts, alternating with the buttermilk, beginning and ending with flour. Mix just until combined.
Divide the batter evenly between the pans and smooth the tops.
Bake for 25–30 minutes, until a toothpick comes out clean. Cool completely before frosting.
In a heavy saucepan, heat the sugar over medium heat, stirring constantly until it melts into an amber-colored liquid.
Carefully add the butter — it will bubble up! Stir until melted.
Slowly pour in the warm cream while stirring (again, expect bubbling!) until smooth.
Remove from heat and stir in sea salt.
Let cool to room temperature. It should thicken as it cools.
Beat the butter until creamy (about 2 minutes).
Add the powdered sugar gradually, beating until fluffy.
Pour in 1/2 cup cooled salted caramel sauce and beat until smooth and delicious.
To Assemble:
