Oh, let me tell you about the first time I made this salted caramel cake—it was love at first bite! That perfect balance of sweet caramel with just a hint of salty goodness had me hooked. I’ve tweaked this recipe over the years until it’s just right—moist layers soaked in homemade caramel, all wrapped up in silky buttercream that melts in your mouth. Whether it’s for birthdays or just because, this cake always feels like a special occasion. Trust me, once you try it, you’ll be making it on repeat (and sneaking spoonfuls of that caramel sauce when no one’s looking).
Why You'll Love This Salted Caramel Cake
Let me count the ways this cake will become your new obsession:
- That perfect sweet-salty punch – The caramel sauce alone is worth making, but when it soaks into those tender cake layers? Wow.
- Looks fancy, comes together easy – I promise, even if you're not a pro baker, you can nail this showstopper.
- Better than any bakery – Fresh caramel made from scratch beats store-bought any day. The flavor is unreal!
- Always a crowd-pleaser – I've never brought this to a gathering without getting recipe requests.
Ingredients for Salted Caramel Cake
Gathering the right ingredients makes all the difference with this cake. Trust me, I learned the hard way – that time I used cold butter straight from the fridge? Let’s just say my arm still aches from all that mixing! Here’s what you’ll need:
- For the cake layers: ¾ cup room temperature salted butter (that means it should leave a slight indent when pressed), 1 ½ cups granulated sugar, ¾ cup light brown sugar (pack it firmly!), 3 large eggs (room temp – I just set mine out an hour before baking), 2 teaspoons vanilla extract (the real stuff, please!), ¾ teaspoon each baking soda and salt, 2 ¼ teaspoons baking powder, 3 ½ cups cake flour (spoon it into the cup and level it off – no packing!), and 1 ½ cups buttermilk (shake the carton first!).
- For the caramel sauce: 2 cups sugar, ½ cup hot water (for dissolving), 12 tbsp room temp cubed butter (I cut mine while watching the sugar cook), 1 cup heavy cream (room temp – cold will make the caramel seize!), and 2 teaspoons vanilla.
- For the frosting: 1 pound room temp cubed salted butter (yes, salted – it balances the sweetness!), 1 cup of your cooled caramel sauce, 2 teaspoons vanilla, ½ teaspoon salt (trust me on this), 5-6 cups powdered sugar (sifted if lumpy), 1-2 tablespoons milk or cream (only if needed), and flaky sea salt for that perfect finishing touch.
Equipment You'll Need
Don't worry – you probably have most of this in your kitchen already! Here's what I always grab when making this cake:
- Stand mixer (or a good hand mixer and some elbow grease)
- 3, 9-inch cake pans – I like the light-colored aluminum ones
- Parchment paper for lining those pans (lifesaver!)
- Silicone pastry brush for caramel-making emergencies
- Heavy-bottomed saucepan – no thin pans for caramel!
- Cake turntable (optional but SO helpful for frosting)
- Piping bag with a ½” round tip if you wanna get fancy
That's it! Now let's get baking.
How to Make Salted Caramel Cake
Okay, let’s dive into the good stuff! I’ll walk you through each step just like I’m right there in the kitchen with you. The secret? Take your time and enjoy the process – good things come to those who wait (especially when caramel’s involved).
Preparing the Cake Layers
First things first – preheat that oven to 350°F and get your pans ready. I learned the hard way that skipping the parchment paper leads to cake disasters! Grease three 9-inch pans and line the bottoms – this little step saves so much frustration later.
Now for the batter: Sift together your dry ingredients (flour, baking powder, soda, and salt) – yes, sifting matters! It makes the cake so light. In your mixer, cream the butter and sugars until they’re fluffy and pale – about 3-4 minutes. Don’t rush this! Add eggs one at a time, then vanilla, mixing well after each.
Here’s my alternating trick: add ⅓ of the buttermilk, then ⅓ of the flour mixture, repeating until everything’s just combined. Overmixing makes tough cakes! Divide the batter evenly (I use a scale to be precise) and bake 20-25 minutes until a toothpick comes out clean. Let them cool in pans for 10 minutes, then transfer to racks. Patience, friend – cold cakes are much easier to frost!
Making the Salted Caramel Sauce
Now for the star of the show! Fill a glass with hot water and keep your pastry brush handy – you’ll thank me later. In a heavy pot, dissolve sugar in hot water over medium-low heat, whisking until clear. Here’s the golden rule: DO NOT stir once it starts boiling! Just swirl the pan occasionally.
Watch closely – it’ll go from clear to amber in what feels like seconds around the 7-minute mark. If sugar crystals form on the sides, dip your brush in hot water and gently wipe them away. When it’s a rich amber color (like iced tea), remove from heat and carefully whisk in the butter – it’ll bubble like crazy but keep stirring! Slowly add cream and vanilla (stand back – more bubbling!), then return to heat for 1 minute to smooth it out. Pour into a jar to cool – resist tasting right away (that molten sugar burns are no joke!).
Assembling the Salted Caramel Cake
Time for the fun part! If your cakes domed, level them with a serrated knife. Whip up your frosting by beating butter with 1 cup cooled caramel until smooth, then mix in vanilla, salt, and powdered sugar. Too thick? Add a splash of milk.
Place your first layer bottom-side up on a plate or stand. Pipe a buttercream dam around the edge (this keeps the caramel from oozing out), then spread ¼ cup caramel inside. Repeat with next layer. For the top, frost the sides first, then the top – no need to be perfect, those caramel drips hide everything! Drizzle remaining caramel over top, letting some drip down the sides, and finish with a pinch of flaky salt. Step back and admire your masterpiece!
Tips for the Perfect Salted Caramel Cake
After making this cake more times than I can count, here are my hard-earned secrets for success:
- Room temp is non-negotiable – Cold butter and eggs won’t cream properly, and chilled cream will make your caramel seize up. I set everything out 2 hours before baking.
- Caramel patience pays off – If your sugar crystallizes, don’t panic! Add 2 tbsp hot water and stir gently over low heat until dissolved. And whatever you do, don’t walk away – amber turns to burnt in seconds!
- Even layers matter – I weigh my batter (about 22oz per 9″ pan) for perfectly equal cakes. A serrated knife levels any domes beautifully.
- Frosting too sweet? Add an extra pinch of salt! The salted butter helps, but sometimes I’ll sneak in another ¼ tsp to balance that caramel.
Remember – even “imperfect” salted caramel cake still tastes incredible!
Variations & Serving Suggestions
Oh, the fun you can have with this cake! Here are my favorite ways to mix it up:
- Chocolate lover's dream – Drizzle melted dark chocolate over the caramel for a decadent twist. I sometimes even add cocoa powder to the cake batter!
- Coffee pairing perfection – Serve slices with strong espresso. The bitterness cuts through the sweetness beautifully.
- Ice cream sandwich – Warm slices slightly and sandwich with vanilla bean ice cream. Messy? Yes. Worth it? Absolutely!
- Nutty variation – Fold toasted pecans or walnuts into the batter for extra crunch.
However you serve it, just make sure there's plenty to go around – this cake disappears fast!
Storing and Reheating
Here’s the good news – this cake actually gets better after a day as the flavors meld! Just pop it in an airtight container at room temp for up to 3 days. The caramel might make the cake a bit sticky, but that’s part of the charm. If you must refrigerate (hello, summer humidity!), let slices come to room temp before serving – cold buttercream is no one’s friend. And whatever you do, don’t microwave it – that caramel turns into molten lava! Trust me, I learned that the hard way with a burnt tongue.
Nutritional Information

Frequently Asked Questions
Q1. Can I use store-bought caramel sauce instead of making my own?
While you can use store-bought in a pinch, homemade caramel makes all the difference in flavor and texture. The stuff in jars often contains thickeners that make the cake layers soggy. But if you’re short on time, look for a high-quality caramel with minimal ingredients – and maybe add an extra pinch of salt to compensate!
Q2. How do I store leftover caramel sauce?
Oh, this one’s easy! Pour any extra caramel into a glass jar and keep it in the fridge for up to 2 weeks. When you’re ready to use it again, just microwave in 15-second bursts, stirring between each, until it’s pourable again. I always make extra – it’s amazing drizzled on ice cream or stirred into coffee! Check out more sweet inspiration on Pinterest.
Q3. My cake layers keep breaking when I assemble them. Help!
Been there! First, make sure your cakes are completely cooled – warm layers are fragile. If they’re still delicate, try brushing them with simple syrup before assembling (equal parts sugar and water, heated until dissolved). This adds moisture and helps hold everything together. And when in doubt, more frosting covers a multitude of sins!
Q4. Can I make this cake ahead of time?
Absolutely! The unfrosted layers freeze beautifully for up to a month – just wrap them tightly in plastic. The caramel sauce keeps in the fridge for 2 weeks. On serving day, thaw the layers at room temp, rewarm the caramel slightly, and assemble fresh. The flavors actually improve after a day!

Description
A rich and decadent salted caramel cake with layers of moist cake, homemade caramel sauce, and creamy buttercream frosting.
Ingredients
- ¾ cup salted butter, room temperature
- 1 ½ cups granulated sugar
- ¾ cup light brown sugar
- 3 large eggs, room temperature
- 2 teaspoons vanilla extract
- ¾ teaspoon baking soda
- ¾ teaspoon salt
- 2 ¼ teaspoons baking powder
- 3 ½ cups cake flour, spooned and leveled
- 1 ½ cup buttermilk
- 2 cups sugar
- ½ cup hot water
- 12 tbsp butter, cubed, room temperature
- 1 cup heavy cream, room temperature
- 2 teaspoons vanilla extract
- 1 pound salted butter, cubed, room temperature
- 1 cup room temperature caramel sauce
- 2 teaspoons vanilla extract
- ½ teaspoon salt
- 5–6 cups powdered sugar
- 1–2 tablespoons milk or cream (if needed)
- Flaky sea salt
Instructions
- Preheat oven to 350℉. Liberally grease 3, 9-inch cake pans and line the bottoms with parchment paper circles.
- In a medium bowl, sift together the flour, salt, baking soda, and baking powder. Set aside.
- In a large mixing bowl using an electric mixer, cream together the butter and sugar until light and fluffy, about 3-4 minutes.
- Add the vanilla extract and the eggs one at a time, until fully incorporated and scraping the bowl after each egg addition. Add in ⅓ of the buttermilk, followed by ⅓ of the flour mixture. Stir after each addition, then continue alternating buttermilk and flour until just combined.
- Evenly divide the batter into the prepared cake pans and smooth out the batter.
- Bake 20-25 minutes until a toothpick inserted in the center comes out clean and the center springs back when lightly touched.
- Cool in the pans for 10 minutes, then remove from the pans to a cooling rack and cool completely.
- Fill a small glass with hot water, and have a silicone pastry brush ready.
- In a large sauce pot, dissolve sugar completely in hot water over medium low, whisking until dissolved and mixture is completely clear, do not allow to boil until sugar is fully dissolved.
- Once sugar is dissolved, stop whisking and increase heat to medium. Swirl the pan, do not stir or whisk, until the sugar is a rich amber color. If sugar crystals form on the side of the pan, dip the pastry brush in hot water and wash the crystals down into the caramel.
- Once the sugar is a rich amber color, remove from heat and whisk in the cubed butter carefully, it will foam up rapidly, but keep whisking until fully combined.
- Whisk in the heavy cream, followed by the vanilla, and return to the heat for 1 minute, whisking rapidly. Remove from heat and pour into a glass bowl or jar to cool to room temperature.
- In the bowl of a stand mixer, using a paddle attachment, cream together the butter and 1 cup of the cooled caramel sauce until smooth and combined, about 2-3 minutes.
- Add the vanilla and salt and mix until combined. Scrape the sides and bottom to be sure everything is evenly incorporated.
- With the mixer on a medium low speed slowly add 5 ½ cups of powdered sugar, scraping occasionally. If the frosting is too thick, add in a tablespoon or two of milk to thin it out to a good piping consistency.
- If desired, once cakes have completely cooled, level off the tops of the cakes with a large serrated knife. Fill a large piping bag fitted with a ½” round tip with buttercream.
- On a cake stand or large platter place the first cake layer bottom side up. Spoon on ¼ cup of the remaining caramel sauce and smooth this thin layer evenly on top of the cake, leaving a ½” border around the outside.
- Place the next cake layer on top and gently press into the bottom layer, repeat the same process with the caramel and buttercream.
- Place the final cake layer on top and very gently press down into the bottom 2 layers. Frost the sides and top of the cake with the remaining buttercream.
- For garnish, top the cake with more caramel sauce, allowing some to drip down the edge of the cake and finish with a sprinkle of a flakey sea salt.
Notes
- Use room temperature ingredients for best results.
- Be careful when making caramel as it gets very hot.
- Store leftover cake in an airtight container.
