These ingredients are simple but essential; each one plays a crucial role in building the perfect texture, flavor, and visual appeal of your Salted Caramel Cake with Caramel Buttercream Recipe. From the smooth butter to the rich sour cream, everything contributes to that beautifully balanced final result.

Granulated sugar (140 g for caramel and 300 g for cake): Essential for creating that deep, golden caramel flavor without bitterness.
Water (1 1/2 tbsp): Helps dissolve the sugar evenly for a smooth caramel base.
Butter (180 g + 40 g for caramel): Adds moisture and richness to the cake and a velvety texture to the caramel.
Heavy cream (150 g): Provides creaminess and helps temper the caramel’s heat, making it perfectly smooth.
Salt (big pinch + 3/4 tsp): Balances sweetness and enhances the caramel’s complexity.
All-purpose flour (340 g): The backbone of the cake’s structure, giving it a tender crumb.
Cornstarch (2 tbsp): Helps keep the cake light and soft.
Baking powder and baking soda (3/4 tsp each): Ensure the cake rises perfectly with just the right texture.
Butter (room temperature, 400 g for frosting): For a rich, creamy caramel buttercream that’s dreamy to frost with.
Powdered sugar (660 g): Sweetens and stabilizes the buttercream for that classic silky finish.
Eggs (4 large, room temp): Bind everything together and add richness.
Sour cream (240 g, 14-18%): Moisturizes the cake and adds a subtle tang that enhances flavor depth.
Vegetable oil (60 g): Keeps the cake tender and moist for days.
Vanilla extract (4 tsp total): Lends warmth and aromatic notes that amplify the caramel beautifully.
Caramel (2-3 tbsp for buttercream, plus extra): The star ingredient that brings everything together.

Directions

Step 1: Start by making the salted caramel sauce. In a medium saucepan, combine the granulated sugar and water, stirring just enough to wet all the sugar evenly. Spread it out into a smooth, flat layer to encourage even melting.

Step 2: Place the saucepan over medium-high heat and watch carefully as the sugar dissolves and begins to turn a beautiful golden brown. Once you notice a light brown color, stir occasionally to ensure everything melts evenly without burning. This step demands patience but trust me, it’s worth it.

Step 3: When your caramel reaches a rich golden color, reduce heat to medium. Stir in the butter until it melts completely into the caramel, then slowly add the heavy cream in small additions. The mixture will bubble strongly, so be careful. Keep stirring constantly until fully combined and silky.

Step 4: Turn off the heat, sprinkle in a big pinch of salt to bring out that salty caramel magic, and transfer the sauce to a shallow bowl. Let it cool in the fridge for about 30 to 60 minutes until it reaches room temperature.

Step 5: While the caramel cools, preheat your oven to 170ºC (340ºF) using the conventional setting. Prepare three 20 cm cake pans by lining them with parchment paper to prevent sticking.

Step 6: Sift together the flour, cornstarch, baking powder, baking soda, and salt into a bowl and set aside.

Step 7: In a large mixing bowl, beat the butter and granulated sugar on high speed for 3 minutes until light and fluffy.

Step 8: Add the eggs two at a time, mixing well after each addition to maintain a smooth batter.

Step 9: On low speed, mix in half of the dry ingredients until just combined.

Step 10: Add the sour cream, vegetable oil, and vanilla extract to the batter, mixing gently to incorporate, then add the remaining dry ingredients and mix until everything is just blended.

Step 11: Use a rubber spatula to fold the batter gently, ensuring no pockets of flour remain.

Step 12: Divide the batter evenly into the three prepared pans and bake for 19-22 minutes. The cakes will be pale and soft to the touch, so check doneness with a cake tester or toothpick coming out clean.

Step 13: Let the cakes cool in their pans for 10 minutes, then carefully remove them and transfer to a wire rack to cool completely before frosting.

Step 14: For the caramel buttercream, sift the powdered sugar to remove lumps and set aside.

Step 15: Beat the butter in a stand mixer or with a hand mixer at medium-high speed for about 4 minutes until pale and creamy. Scrape down the bowl and beat an additional 2 minutes for a smooth consistency.

Step 16: Add the powdered sugar, vanilla extract, and caramel in two parts, whipping well after each addition. Finish with a low-speed mix for about 1 minute until perfectly blended.

Step 17: To assemble your cake, place the first layer on your chosen serving board. Spread 2 big scoops of buttercream evenly over the cake, followed by 2-3 tablespoons of caramel, leaving a small gap at the edges to prevent overflow.

Step 18: Repeat with the next layer, then top with the final cake layer. Apply a thin crumb coat all over and chill the cake in the fridge for 20 minutes to set.

Step 19: Finish frosting the cake with the remaining buttercream, smoothing the sides and top. Drizzle the remaining caramel over the cake’s surface, swirling it gently into the buttercream if you like for a pretty marbled effect.

Servings and Timing

This Salted Caramel Cake with Caramel Buttercream Recipe yields about 12 generous servings, perfect for sharing with family or friends. Prep time takes roughly 25-30 minutes, with an additional hour for baking the layers. Don’t forget to factor in 30-60 minutes for the caramel to cool and about 20 minutes chilling after applying the crumb coat. All in, you’re looking at approximately 1 hour and 5 minutes of active work, plus some waiting time, but the results make every minute worthwhile.

When it comes to serving this cake, I love to keep things simple yet elegant. This dessert pairs wonderfully with a cup of freshly brewed coffee or a rich black tea, which balance the sweetness perfectly. If it’s a special celebration, a glass of dessert wine or a smooth bourbon makes a fantastic adult pairing that echoes the caramel notes beautifully. For a non-alcoholic option, I’d recommend a sparkling apple cider or a lightly spiced chai latte.

Presentation-wise, I like to slice the cake into generous portions of about 1.5 to 2 inches wide. I often add a sprinkle of flaky sea salt on top just before serving for that extra pop of texture and crunch. A few caramel shards or a scattering of toasted nuts on the plate can elevate the look effortlessly. Serving it at room temperature is best—the buttercream softens just enough, allowing all the flavors to shine without becoming too melty.

This cake is ideal for family dinners, holiday gatherings, or simply when you want to treat yourself and your loved ones. It’s impressive enough to wow guests but cozy enough to enjoy as a weeknight dessert. If you want to take the wow factor up a notch, try serving each slice with a scoop of vanilla bean ice cream or a dollop of freshly whipped cream.

Variations

I love tweaking this Salted Caramel Cake with Caramel Buttercream Recipe to suit different tastes or dietary needs. For a gluten-free version, I swap the all-purpose flour for a high-quality gluten-free blend that includes xanthan gum to maintain the cake’s tender crumb. The texture remains surprisingly close to the original, and the flavor is just as indulgent.

If you’re vegan or simply want a dairy-free option, I’ve had great success replacing butter with vegan butter alternatives and swapping heavy cream with canned coconut milk for the caramel. Use flax eggs in place of the regular eggs, and the cake still turns out moist and delicious. Just be mindful the flavors shift slightly toward coconut, which pairs nicely with caramel.

For flavor variations, you could add a teaspoon of espresso powder to the cake batter to deepen the caramel’s richness or mix in chopped toasted pecans into the layers for extra texture. Alternatively, try baking the cake as cupcakes for an easier, portion-controlled treat that’s perfect for parties. I’ve also experimented with a browned butter caramel sauce variation, adding a nutty complexity that’s absolutely divine.

Storage and Reheating

Storing Leftovers

Once your cake is frosted and assembled, I recommend storing leftovers in an airtight container or covered with plastic wrap to prevent the buttercream from drying out. Keep the cake refrigerated, especially because of the buttercream and caramel, to maintain freshness. It will stay delicious for about 3 to 4 days, but if you prefer the cake closer to room temperature, remove it from the fridge 30 minutes before serving.

Freezing

This Salted Caramel Cake with Caramel Buttercream Recipe freezes very well, which is great if you want to prepare it ahead of time. For best results, freeze the cake unfrosted by wrapping each cooled layer tightly in plastic wrap and then in aluminum foil. Freeze for up to 2 months. When you’re ready, thaw the layers overnight in the refrigerator before assembling and frosting. You can also freeze a fully frosted cake, but make sure it’s well wrapped to avoid freezer burn and allow extra thawing time for the buttercream to soften.

Reheating

I typically do not recommend reheating this cake since it’s best enjoyed at room temperature or slightly chilled. However, if you want to bring it closer to room temperature quickly, leave the slice on the counter for about 20-30 minutes before serving. Avoid microwaving it, as this can alter the texture of the cake and make the buttercream oily or melt unevenly. The key to enjoying the best texture and flavor is to serve it gently rested rather than heated.

FAQs

Can I make the caramel sauce ahead of time?

Yes! You can prepare the salted caramel sauce a day or two in advance. Store it in an airtight container in the fridge, and bring it to room temperature before using in the buttercream or layering. Just give it a good stir to reincorporate any settled bits.

What if my caramel burns while making it?

If your caramel gets too dark or smells burnt, it’s best to start over. Burnt caramel tastes bitter and will affect the entire cake’s flavor. Remember to watch the sugar closely and remove it from heat as soon as it’s a deep golden color for best results.

Can I use salted butter instead of unsalted?

I prefer unsalted butter so I can control the amount of salt in the recipe precisely, especially since the salted caramel already contains salt. If you use salted butter, reduce added salt slightly to avoid over-salting the cake.

How do I prevent the cake layers from drying out?

Using sour cream and vegetable oil in this recipe helps keep the cake moist for several days. Another tip is to wrap leftover slices tightly with plastic wrap to lock in moisture. Serving the cake close to room temperature also keeps the texture enjoyable.

Is it necessary to chill the cake between crumb coat and final frosting?

Chilling the cake after applying the crumb coat helps set a firm base layer, which makes spreading the final frosting much easier and results in a cleaner, smoother appearance. I highly recommend this step, especially if you want a polished, professional look.
