Ingredients

The foundation of this cake relies on high‑quality butter, fine cake flour, and real buttermilk to create a tender crumb.

Finally, a bourbon‑infused buttercream ties everything together, giving a subtle warmth that elevates the whole dessert.

Cake Base

• 2 ½ cups cake flour

Salted Caramel Sauce

• 1 cup granulated sugar
• ½ cup heavy cream, warmed
• ¼ cup unsalted butter, cubed
• 1 tsp flaky sea salt, plus extra for garnish

Bourbon Buttercream

• ½ cup unsalted butter, softened
• 2 cups powdered sugar, sifted
• 2 tbsp Kentucky bourbon
• 1 tsp pure vanilla extract

Together these ingredients create a harmonious balance: the cake’s tender crumb absorbs the buttery caramel, while the bourbon buttercream adds a mellow warmth. The sea‑salt crystals sprinkled on top provide that essential contrast, turning each bite into a perfect sweet‑salty experience that’s unmistakably Southern.

Step-by-Step Instructions

Preparing the Dry Ingredients

In a medium bowl whisk together cake flour, baking powder, baking soda, and fine sea salt. Whisking ensures even distribution of leaveners and prevents pockets of salt, which could create uneven rise in the finished layers.

Mixing the Batter

1. Cream the Butter & Sugar. Using a handheld mixer on medium speed, beat unsalted butter and granulated sugar until pale and fluffy, about 3–4 minutes. This incorporates air, giving the cake lift.
2. Add Eggs & Vanilla. Add the eggs one at a time, beating well after each addition, then stir in vanilla extract. The eggs bind the batter and contribute richness.
3. Incorporate Dry Ingredients & Buttermilk. Alternate adding the dry mixture and chilled buttermilk, beginning and ending with the dry ingredients. Mix on low just until combined; over‑mixing would develop gluten and make the crumb tough.

Baking the Cake

Preheat the oven to 350°F (175°C). Grease two 9‑inch round cake pans, line the bottoms with parchment, then divide the batter evenly. Bake for **22‑25 minutes**, or until a toothpick inserted in the center emerges clean. The edges should be lightly golden, and the tops should spring back when pressed lightly.

Making the Salted Caramel Sauce

1. Caramelize the Sugar. In a heavy saucepan over medium‑high heat, melt granulated sugar without stirring. Swirl the pan gently; the sugar will turn amber after 5‑7 minutes. Watch closely to avoid burning.
2. Add Butter & Cream. Remove the pan from heat, whisk in cubed butter until melted, then slowly drizzle in warmed heavy cream. The mixture will bubble vigorously—continue whisking until smooth.
3. Season. Stir in flaky sea salt. Let the sauce cool to room temperature; it will thicken as it stands, becoming perfect for glazing.

Bourbon Buttercream & Assembly

While the cakes cool, beat softened butter until creamy, then gradually add powdered sugar, bourbon, vanilla, and a pinch of salt. Beat on high for 2‑3 minutes until light and fluffy. Level the cooled cake layers, spread a generous layer of buttercream, place the second layer, then drizzle the salted caramel over the top, allowing it to drip down the sides. Finish with a light dusting of sea‑salt crystals for that signature sweet‑salty pop.

Tips & Tricks

Perfecting the Recipe

Flavor Enhancements

Add a splash of dark rum or a pinch of cinnamon to the caramel for a deeper spice note. For extra buttery richness, stir in a tablespoon of browned butter into the frosting. Finish each slice with a drizzle of extra caramel and a few crushed pecans for texture.

Common Mistakes to Avoid

Never rush the caramelization step; burning sugar creates bitterness. Also, avoid adding cold cream to hot caramel—it can cause the mixture to seize. Finally, don’t forget to measure the sea‑salt; too much will overwhelm the sweetness.

Pro Tips

Variations

Ingredient Swaps

Replace the buttermilk with whole‑milk yogurt for a tangier crumb, or swap bourbon for a splash of vanilla‑infused bourbon for a subtler flavor. For a nutty twist, fold in toasted pecans or walnuts into the batter before baking.

Dietary Adjustments

Use gluten‑free flour blend in place of cake flour, ensuring it contains a starch‑plus‑protein mix. Substitute the butter in the frosting with a plant‑based margarine and use coconut cream in the caramel for a dairy‑free version. For a lower‑sugar option, halve the granulated sugar and replace half of the powdered sugar with a sugar substitute that measures cup‑for‑cup.

Serving Suggestions

Serve the cake with a dollop of lightly sweetened whipped cream and fresh berries for a bright contrast. Pair it with a chilled glass of bourbon‑infused coffee or a sparkling mimosa for a brunch‑worthy presentation. For a festive touch, garnish with edible gold leaf or a drizzle of dark chocolate.

Storage Info

Leftover Storage

Allow any leftover cake to cool completely, then wrap each slice tightly in plastic wrap and place in an airtight container. Store in the refrigerator for up to 4 days. For longer keeping, freeze slices in a freezer‑safe bag; they retain flavor for up to 3 months.

Reheating Instructions

Reheat individual slices in a 300°F (150°C) oven for 10‑12 minutes, loosely covered with foil to prevent drying. Alternatively, microwave a slice on medium power for 30‑45 seconds, then drizzle a little extra caramel to revive the glossy finish.
