- 1/2 teaspoon salt
- 1 cup granulated sugar
- 1 cup packed brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup whole milk
- 1/2 cup vegetable oil
- 1 cup boiling water
Salted Caramel Sauce Ingredients (Homemade)
- 1/2 cup unsalted butter
- 1/2 cup brown sugar
- 1/4 cup heavy cream

Salted Caramel Buttercream Ingredients
- 1 cup unsalted butter, softened (divided: 1 cup total butter with 1/2 cup used in caramel, 1/2 cup for buttercream)
- 4 cups powdered sugar
- 1/2 cup salted caramel sauce (store-bought or homemade)
- 1 teaspoon vanilla extract
- 1/4 teaspoon salt (optional, depending on caramel saltiness)
Instructions
- Prepare the cake batter: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to prevent sticking.
- Mix dry ingredients: In a medium bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
- Cream sugars and eggs: In a large bowl, beat the granulated sugar, brown sugar, eggs, and vanilla extract until the mixture is smooth and well combined.
- Add dry and wet ingredients: Alternately add the dry ingredient mixture with the milk and vegetable oil into the wet mixture, mixing just until combined to avoid overmixing.
- Incorporate boiling water: Stir in the boiling water carefully; this will thin the batter but intensify the chocolate flavor.
- Pour into pans and bake: Evenly divide the batter between the prepared pans and bake for 30-35 minutes until a toothpick inserted in the center comes out clean.
- Cool cakes: Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
- Make homemade salted caramel sauce (optional): In a medium saucepan, melt 1/2 cup unsalted butter over medium heat. Stir in 1/2 cup brown sugar and bring to a boil. Cook for about 2 minutes while stirring constantly.
- Add cream and thicken sauce: Carefully add the heavy cream (it will bubble), reduce heat, and stir for 3 minutes until the sauce slightly thickens.
- Finish caramel sauce: Stir in vanilla extract and a pinch of salt, then remove from heat and let cool to room temperature.
- Prepare buttercream: In a large bowl, beat the softened butter until light and creamy. Gradually add powdered sugar, one cup at a time, beating well after each addition.
- Add salted caramel and vanilla: Mix in the cooled salted caramel sauce and vanilla extract until smooth. Taste and add salt if needed to balance sweetness.
- Assemble the cake: Place one cooled cake layer on a serving plate. Spread a generous layer of salted caramel buttercream on top.
- Layer and frost: Place the second cake layer on top and cover the entire cake with the remaining buttercream.
- Optional decoration: Drizzle extra salted caramel sauce over the frosted cake for added flavor and a beautiful finish.
- Set and serve: Allow the assembled cake to rest for 15-20 minutes so the frosting firms up. Slice and enjoy this decadent dessert!
Notes
- Ensure the cake layers are completely cooled before frosting to prevent buttercream from melting.
- You can use store-bought salted caramel sauce to save time.
- Adjust the amount of salt in the buttercream to balance the sweetness per your taste.
- For an extra rich cake, substitute whole milk with buttermilk.
- This cake keeps well refrigerated for up to 3 days; bring to room temperature before serving.
