Salted Caramel Chocolate Cake (Caramel Chocolate Frosting)

Please share this post with your friends 🤗

This is a classic, dramatic layer cake that’s equal parts chocolate and salted caramel. It’s rich but balanced: a tender, deeply chocolate crumb layered with buttery caramel and a silky chocolate-caramel frosting. The result is bakery-caliber without requiring temperamental techniques.

I keep the method straightforward so you can focus on timing and simple tricks—lined pans, hot water for a thin batter that yields a moist crumb, and a chilled set before finishing the frosting. Read through once before starting; the cake bakes on a schedule and the frosting benefits from very soft butter and a bit of chilling.

This recipe makes three 9-inch cake layers with a caramel-forward frosting and a glossy salted finish. Follow the stepwise instructions and tips below for reliable results, plus swaps and storage guidance so you can adapt it for different occasions or diets.

Ingredients at a Glance

2 cups granulated sugar — primary sweetener for the cake; helps with tender crumb and browning.

1 cup light brown sugar, packed — adds moisture and caramel notes to the cake.

2 3/4 cups all-purpose flour (not packed!) — structure; measure by spooning into cup then leveling.

1 1/2 cups unsweetened cocoa powder, sifted — deep chocolate flavor; sift to avoid lumps.

3 teaspoons baking soda — leavening to lift the layers.

1 1/2 teaspoons baking powder — additional lift and crumb lightness.

1 1/4 teaspoons salt — balances sweetness and enhances chocolate.

3 large eggs + 2 large egg yolks, at room temperature — binders and richness; room temp improves emulsification.

1 1/2 cups full-fat sour cream — adds tang and moisture to the cake batter.

1/3 cup whole milk — thins batter slightly and adds tenderness.

3/4 cup vegetable oil — keeps cake moist; can sub melted coconut oil if desired.

2 tablespoons vanilla extract — flavor enhancer for the cake.

1 1/2 cups hot water — thins batter, intensifies cocoa; use very hot but not boiling.

2 cups unsalted butter (4 sticks, 16 ounces), VERY soft — base for the frosting; must be soft for smooth creaming.

4 1/2 cups confectioners’ sugar, sifted — sweetens and thickens the frosting; sifted for lump-free texture.

3/4 cup unsweetened cocoa powder, sifted — chocolate component of the frosting; sift for smoothness.

1 teaspoon vanilla extract — flavor boost for the frosting.

1/2 teaspoon salt — balances sweetness in the frosting.

3 tablespoons heavy cream (more if needed) — thins frosting to spreadable consistency.

2 tablespoons salted caramel sauce — folded into the frosting for caramel flavor.

1 1/4 cups salted caramel sauce — used between layers and for drizzle; keep at room temp for easy spreading.

Flaky sea salt — finishing touch; adds crunch and highlights the caramel.

Salted Caramel Chocolate Cake (Caramel Chocolate Frosting) Made Stepwise

1. Preheat and prepare pans. Preheat oven to 350°F. Cut three 9-inch circles of parchment to fit the bottoms of your pans. Spray the sides and bottoms of each pan generously with nonstick spray, place the parchment circles in the bottoms, and spray the paper as well. Make sure all pan surfaces and the parchment are well-coated so the cakes release cleanly.

2. Combine dry ingredients. In the bowl of a stand mixer fitted with the paddle attachment, or in a large bowl with a handheld mixer, add 2 cups granulated sugar, 1 cup packed light brown sugar, 2 3/4 cups all-purpose flour, 1 1/2 cups sifted unsweetened cocoa powder, 3 teaspoons baking soda, 1 1/2 teaspoons baking powder, and 1 1/4 teaspoons salt. Mix on low until everything is evenly combined. Break up any clumps of cocoa or sugar with your hands if needed.

3. Combine wet ingredients. In a separate bowl whisk together 3 large eggs plus 2 large egg yolks, 1 1/2 cups full-fat sour cream, 1/3 cup whole milk, 3/4 cup vegetable oil, and 2 tablespoons vanilla extract until smooth and homogenous.

4. Bring batter together. Pour the wet mixture into the dry ingredients and mix on low speed just until incorporated—do not overmix. With the mixer running on low, pour in 1 1/2 cups hot water. Continue mixing for about 1 minute until the batter is completely combined. Expect a fairly thin batter; that’s normal and produces a moist cake.

5. Bake the layers. Divide the batter evenly between the three prepared pans. Bake in the preheated 350°F oven for about 30 minutes. Test by inserting a wooden toothpick or cake tester in the center; it should come out clean or with only a few moist crumbs attached.

6. Cool the layers. Allow the cakes to cool in their pans for 10 minutes. Run a thin knife around the edges, invert to remove each cake, peel off the parchment, and transfer to a wire rack to cool completely before frosting.

7. Prepare the frosting base. In a stand mixer fitted with the paddle attachment, beat 2 cups very soft unsalted butter on medium speed until completely smooth, about 3 minutes.

8. Add the dry frosting ingredients. Turn the mixer off and sift 4 1/2 cups confectioners’ sugar and 3/4 cup sifted unsweetened cocoa powder into the bowl. Start the mixer on the lowest speed and mix until the sugar and cocoa are absorbed by the butter, about 2 minutes.

9. Finish the frosting. Increase the mixer speed to medium and add 1 teaspoon vanilla extract, 1/2 teaspoon salt, 3 tablespoons heavy cream, and 2 tablespoons salted caramel sauce. Beat for 3 minutes until the frosting is smooth and spreadable. If the frosting seems too thin, add small amounts of additional confectioners’ sugar. If it’s too thick, add extra heavy cream, 1 tablespoon at a time, until you reach the desired consistency.

10. Level the cake layers. Using a serrated knife, carefully trim the domed tops from each cooled cake to create even, level layers.

11. Build the cake. Place one layer on a cake stand or large plate. Spread a thin layer of frosting over the top, then spoon and spread 1/2 cup salted caramel sauce over the frosting. Add the second cake layer, repeat the thin frosting layer and another 1/2 cup of caramel. Place the final cake layer on top.

12. Chill briefly, then finish. Refrigerate the assembled, unfrosted sides-of-cake for 1 hour to help the caramel set and to make final frosting easier. After chilling, finish frosting the top and sides with the remaining frosting until smooth.

13. Finish and serve. Sprinkle flaky sea salt over the top to taste. Slice and serve, or keep refrigerated for up to 5 days.

What Makes This Recipe Special

This cake balances intense cocoa and buttery caramel without becoming cloying. The hot water in the batter helps bloom the cocoa, giving deep chocolate flavor while keeping the crumb moist and tender. Using both granulated and brown sugar adds complexity—granulated for structure and brown sugar for that toffee-like note. The frosting is essentially a chocolate buttercream cut with real salted caramel, so each bite hits both chocolate and caramel in a single forkful. Finally, the chill step before final frosting prevents the caramel between layers from oozing and helps you get clean sides.

Smart Substitutions

Vegetable oil — you can substitute melted coconut oil (same quantity) for a subtle coconut note.

Full-fat sour cream — plain Greek yogurt works in a pinch but expect slightly tangier flavor and a touch less richness.

Hot water — use hot coffee for a deeper chocolate flavor without changing quantities.

Salted caramel sauce — if you only have unsalted caramel, add a pinch of flaky sea salt between layers and to the frosting to mimic the salt balance.

Recommended Tools

Three 9-inch cake pans — for even layers; use metal pans for consistent browning.

Parchment paper and nonstick spray — essential for clean release.

Stand mixer with paddle attachment — speeds batter assembly and gives the creamiest frosting; handheld mixer works too.

Sifter or fine-mesh sieve — for smooth cocoa and confectioners’ sugar in the frosting.

Serrated knife or cake leveler — creates level layers for neat stacking.

Offset spatula and bench scraper — for smooth frosting application and tidy sides.

Errors to Dodge

Skipping pan preparation — not spraying parchment thoroughly causes sticking and broken layers.

Overmixing after adding water — mix only until combined; overworking batter can lead to a tough crumb.

Frosting with cold butter — the butter must be VERY soft. Cold butter lumps and results in a grainy frosting.

Assembling while layers are warm — wait until cakes are completely cool, and chill briefly after adding caramel so the filling doesn’t run.

Adding too much liquid to frosting at once — thin gradually, 1 tablespoon at a time, to avoid frosting that won’t hold shape.

Fresh Takes Through the Year

Winter

Swap hot water for hot espresso and dust the final cake with cocoa powder for a mocha twist. Add a few toasted hazelnuts between layers for crunch.

Spring

Layer thinly sliced strawberries or raspberry compote between cake layers in place of half the caramel to brighten the flavor.

Summer

Use salted caramel ice cream alongside slices for a cool pairing, or serve mini versions as cupcakes with a caramel center.

Fall

Stir 1/2 teaspoon ground cinnamon into the cake batter and a pinch of nutmeg into the frosting for warm spice notes that pair with caramel.

Flavor Logic

Chocolate brings bitterness and depth; caramel supplies fat, butteriness, and sweet-toffee notes. Salt lifts both and sharpens the flavors. Sour cream contributes tang and moisture while oil keeps the crumb soft for days. The hot water blooms cocoa, ensuring the chocolate taste is forward even with a rich caramel presence. Structurally, the combination of baking soda and baking powder provides lift and tenderness without a coarse crumb.

Shelf Life & Storage

Store the finished cake covered and refrigerated for up to 5 days. If you want to keep it longer, freeze individual slices wrapped tightly in plastic and then foil for up to 2 months; thaw overnight in the fridge. Before serving, bring slices to room temperature for the best texture and flavor. If storing in a warm environment, keep the cake chilled so the caramel and frosting hold their shape.

Frequently Asked Questions

Q: Can I make this as a two-layer cake instead of three?
A: Yes. Use two 9-inch pans, divide the batter evenly, and adjust bake time—start checking at 25 minutes.

Q: My frosting is grainy—what happened?
A: Likely the butter was too cold or your confectioners’ sugar wasn’t sifted. Beat the frosting longer at medium speed, and sift the sugar/cocoa before adding.

Q: Can I use salted butter instead of unsalted?
A: Yes—omit or reduce the 1/2 teaspoon salt in the frosting if you do.

Q: How do I keep the caramel from sliding out of the layers?
A: Trim and level layers, apply a thin crumb coat of frosting first, then add caramel. Chill the cake for 1 hour before finishing the outer frosting.
