Salted Caramel Kentucky Butter Cake Recipe: INA Garten's Moist Layers and Buttery Frosting Bliss

Ina Garten’s salted caramel Kentucky butter cake—this luscious recipe delivers moist, buttery layers and a rich caramel filling that make every slice feel like a celebration.

After perfecting my grandmother’s Sunday roast chicken, I’ve spent years refining desserts that balance indulgence with precision—and this cake is the result of that dedication. The secret lies in creaming butter and sugar to perfection, then layering it with a velvety salted caramel that ties everything together.

What makes this recipe special is the foolproof technique for achieving tender, moist layers without a dense crumb. The buttery frosting, infused with vanilla and a touch of bourbon, complements the caramel beautifully, while flaky sea salt and candied pecans add texture and sophistication.

I’ve tested this with home bakers of all skill levels, and even those who struggle with baking achieve perfect results.

By the time you slice into this cake, you’ll taste layers of buttery richness, a gooey salted caramel center, and a frosting so smooth it melts in your mouth. The aroma alone—warm caramel and vanilla—will have everyone gathered around the table.

This is the kind of dessert that feels like a hug, perfect for birthdays, holidays, or simply treating yourself.

Ready in about 2 hours (including cooling), this cake requires no fancy equipment—just patience and attention to detail. The assembly process is straightforward, and the final plating elevates it from homemade to restaurant-worthy. Let’s get started on creating your new favorite dessert.

Buttery layers, gooey caramel, and bourbon-kissed frosting—this cake delivers pure indulgence with just 15 ingredients.

The butter is non-negotiable here—European-style unsalted butter (like Plugrá or Land O’Lakes European) gives the richest flavor. Grab it from the grocery store’s international section or order online. The sugar matters too: superfine sugar blends smoother, but if you only have regular granulated, pulse it in a food processor first. Eggs should be room temperature—cold ones cause dense layers. For the bourbon, Buffalo Trace or Maker’s Mark add depth without overpowering. If you’re avoiding alcohol, substitute with vanilla bean paste or extra vanilla extract.

No bourbon? Dark rum or even more vanilla extract works in a pinch. The candied pecans can be swapped for toasted walnuts if you’re nut-averse, but trust me—they’re worth the extra crunch. For the caramel filling, light corn syrup keeps it silky; honey works too but changes the texture slightly. The sea salt? Maldon flaky salt is ideal, but any good flaky salt (like Diamond Crystal) does the trick. Prefer less salt? Reduce to 2 tbsp and sprinkle lightly. The frosting’s secret? Chill the butter and cream for 30 minutes before whipping—it’s the difference between fluffy and greasy.

Store the cake components separately: frosting lasts 5 days in the fridge, layers stay fresh for 3 days wrapped tightly. Assemble just before serving—this cake tastes best the day it’s made. For make-ahead magic, bake the layers, cool, then freeze them wrapped in plastic for up to 1 month. The caramel filling can be made a day ahead and reheated gently. Garnish with extra pecans and flaky salt right before serving—that’s when it shines.

Step-by-step instructions for salted caramel Kentucky butter cake

Here's how to create INA Garten's legendary cake with rich, moist layers and velvety buttercream.

In a stand mixer fitted with the paddle attachment, beat the 1.5 cups unsalted butter and 2.5 cups granulated white sugar on medium speed for 3-4 minutes until light and fluffy. You'll see the mixture nearly double in volume and become pale. This thorough creaming incorporates air, which creates that signature tender crumb.

I like to scrape down the sides of the bowl every 30 seconds to ensure even mixing. The butter should be completely smooth with no graininess remaining. If you're using room temperature butter, this step will take slightly longer—just be patient. The key here is achieving that perfect ribbon stage where the mixture holds its shape when the paddle is lifted.

Add the 6 whole large eggs, one at a time, mixing well after each addition. Then stir in the 2 teaspoons pure vanilla extract and 2 tablespoons bourbon whiskey. The whiskey adds depth that complements the caramel perfectly. Mix just until combined—overmixing develops gluten and can make the cake slightly tough.

Here's the thing—don't rush this step. The mixture should be smooth but still slightly thick. If you're worried about the eggs breaking, add them one at a time with the mixer on low speed. The vanilla and bourbon should be fully incorporated, but don't overwork the batter at this stage. We'll add the dry ingredients next to create the perfect texture.

In a separate bowl, whisk together the 3.5 cups all-purpose flour, 2 tablespoons baking powder, and 1.5 teaspoons salt. Sift the flour mixture directly into the wet ingredients, mixing on low speed just until combined. You should still see some flour streaks—this ensures a tender cake rather than a dense one.

I always use a light hand when mixing the dry ingredients. The moment everything comes together is perfect. Don't overmix—this is where many cakes go wrong. The batter should be thick but pourable. If it looks too stiff, you can gently fold in 1 tablespoon of heavy whipping cream to help it along, but usually, it comes together beautifully on its own.

Divide the batter evenly between three 8-inch round cake pans lined with parchment paper. Bake at 350°F for 25-30 minutes or until a toothpick inserted in the center comes out clean. The cakes should spring back gently when touched and have a golden top.

Don't open the oven during baking—this causes the cakes to sink. I recommend rotating the pans halfway through for even baking. The cakes are done when they pull away slightly from the edges of the pan and have a springy texture. Let them cool in the pans for 10 minutes before transferring to a wire rack to cool completely. This resting period helps them set properly for slicing.

In a saucepan, combine the 2 cups heavy cream, 1.5 cups brown sugar, and 0.5 cup corn syrup. Bring to a boil over medium heat, then reduce to a simmer and cook for 10-12 minutes until the mixture thickens to a caramel consistency. Remove from heat and stir in 0.25 cup flaky sea salt—this is where the magic happens.

Let the caramel cool slightly before using. It should be thick enough to pipe but still spreadable. I like to work quickly here to maintain the perfect texture. The caramel should coat the back of a spoon and hold its shape when piped. If it's too thick, warm it gently over low heat and stir until smooth again.

Beat the 1.5 cups heavy whipping cream to stiff peaks, then gradually add the 4 cups powdered sugar and 2 teaspoons vanilla extract, beating until smooth and fluffy. Spread a layer of buttercream between each cake layer, then pipe additional buttercream around the edges of the cake. Fill the center with the salted caramel, then top with the final cake layer.

Press the 1.5 cups candied pecans into the sides of the cake for decoration. I like to do this gently so they stick well. Chill the cake in the refrigerator for at least 2 hours before serving. This resting time allows all the flavors to meld together perfectly. The result is a cake that's rich, moist, and bursting with caramel and salted buttercream in every bite.

Serving suggestions for leftovers

Plating Like a Pro

Slice this cake with a serrated knife dipped in hot water and wiped clean between slices. The hot knife creates smooth edges and prevents crumbs. Serve on a wooden cake stand or white porcelain platter to let the caramel and buttercream shine.

I like to arrange slices in a circular pattern for an elegant presentation. 🍰

Garnish Game-Changers

Freshly toasted pecans add a smoky contrast to the sweet caramel. Sprinkle them over each slice right before serving. For extra flair, drizzle extra salted caramel sauce in a zigzag pattern across the top.

A pinch of flaky sea salt on the frosting enhances the salty-sweet balance. These garnishes take your cake from homemade to showstopper.

Portion Control Tips

This cake is decadent, so I recommend 1-2 slices per person for a full dessert course. For a lighter option, serve with a dollop of vanilla bean ice cream or a scoop of bourbon-infused whipped cream.

The contrast of cold and warm textures makes each bite unforgettable. If you're serving a crowd, cut the cake into 12 equal wedges for easy portioning.

Serving Temperature

Serve this cake at room temperature for the best texture and flavor. If you've chilled it, let it sit for 15-20 minutes before serving so the frosting softens slightly.

Cold frosting can feel heavy, but at room temperature, it melts beautifully in your mouth. I always serve mine slightly warm—it’s the perfect balance of indulgence and ease.

Pairing with Drinks

A glass of chilled bourbon (like Maker’s Mark) complements the cake’s flavors perfectly. For a non-alcoholic option, try sweet tea or vanilla chai latte. The warmth of the tea cuts through the richness, while the spices in chai add an unexpected depth.

Coffee lovers can enjoy a dark roast to balance the sweetness. 🍷

Make-Ahead Serving

Assemble the cake up to 2 days in advance and store it in an airtight container at room temperature. The flavors deepen over time, making it even more delicious. If you're serving it later, cover it loosely with plastic wrap to prevent drying.

For a restaurant-style presentation, dust the top with powdered sugar just before serving—it adds a professional touch that guests will notice.
