Salted Caramel Kentucky Butter Cake Recipe Ina Garten: Decadent Layers of Rich Flavor

This cake redefines indulgence with its buttery richness and gooey caramel layers that make every bite unforgettable.

The secret lies in the browned butter and precise layering technique that creates a moist, dense crumb with pockets of sweet, salty caramel throughout. Each slice reveals a perfect balance of flavors, from the deep, nutty butter to the smooth, golden caramel.

What sets this version apart is the addition of flaky sea salt, which elevates the sweetness and adds a sophisticated finish. The cake bakes up with a tender texture and a subtle crunch from the caramelized edges.

Serve it warm or at room temperature for a dessert that impresses without effort. This is comfort baking at its finest.

Ingredients for Salted Caramel Kentucky Butter Cake Recipe Ina Garten

Rich butter, golden caramel, and a touch of salt create this showstopping dessert.

The butter is everything here. Use high-quality unsalted—Plugrá or Kerrygold if you can find it. Browning it transforms the flavor completely (that nutty aroma is non-negotiable). The flour should be fresh—check the expiration date. Most supermarkets carry King Arthur all-purpose, which is a reliable choice for consistent results.

No buttermilk? Mix 1 cup milk with 1 tbsp vinegar and let sit for 5 minutes. Brown sugar can be swapped with coconut sugar, but the molasses notes add depth. If you’re out of vanilla extract, vanilla bean paste works beautifully. The heavy cream in the caramel is essential—don’t substitute with milk or it won’t set properly (trust me on this).

The cake stays moist for 3-4 days at room temperature, wrapped tightly. Caramel can be made 2 days ahead and reheated gently. Always use airtight containers—this dessert hates dry air. Leftovers? Reheat slices for 15 seconds in the microwave for that fresh-baked feel.

Step-by-Step Instructions for Salted Caramel Kentucky Butter Cake

Master the technique behind this showstopping dessert with precision at every stage.

Step 1: Prepare the Cake Batter Base

Preheat your oven to 325°F and grease a 10-inch bundt pan thoroughly. In a large bowl, cream together the 1.5 cups Unsalted Butter with the 2 cups Granulated Sugar and 1 cup Light Brown Sugar until light and fluffy—about 4-5 minutes on medium speed.

Add the 4 whole Large Eggs one at a time, mixing well after each addition. Then incorporate the 2 tsp Vanilla Extract. This creates a smooth emulsion that ensures a tender crumb in your finished cake.

In a separate bowl, whisk together the 3 cups All-Purpose Flour, 1 tsp Baking Powder, 0.5 tsp Baking Soda, and 1 tsp Salt. Alternate adding this dry mixture and the 1 cup Buttermilk to your butter mixture, beginning and ending with the flour. Mix just until combined to avoid overdevelopment of gluten.

Step 2: Bake and Prepare Caramel Glaze

Pour the batter into your prepared bundt pan and bake for 60-70 minutes, or until a toothpick inserted into the center comes out clean. While the cake bakes, begin making the caramel glaze by melting ½ cup Unsalted Butter in a saucepan over medium heat.

Add the remaining 1 cup Granulated Sugar and cook, stirring constantly, until the mixture turns a deep amber color—about 8-10 minutes. Slowly whisk in the 0.5 cup Heavy Cream (the mixture will bubble vigorously) and continue cooking for 2-3 minutes until smooth.

Step 3: Glaze and Finish the Cake

Remove the cake from the oven and let it cool in the pan for 10 minutes, then invert it onto a wire rack to cool completely. Once the cake is warm but not hot, poke holes all over the top with a wooden skewer—this allows the caramel to penetrate deeply.

Pour the warm caramel glaze evenly over the cake, letting it soak in and drip down the sides. Immediately sprinkle with 0.5 tsp Flaky Sea Salt while the caramel is still sticky to ensure it adheres properly.

For an optional finishing touch, dust with 0.5 cup Confectioners’ Sugar just before serving. The contrast of sweet caramel and salty flakes creates the signature flavor profile of this decadent dessert.

Step 4: Rest and Serve

Allow the glaze to set for at least 30 minutes before slicing. This resting period lets the caramel firm up slightly while still maintaining its gooey texture. The cake should have a golden-brown crust with a moist, dense interior.

Serve at room temperature for the best texture. Each slice should reveal layers of rich butter cake infused with caramel, finished with a delicate balance of sweet and salty notes that make this Kentucky classic unforgettable.

Common Mistakes When Making This Recipe

Overmixing the Batter

Once you add the flour mixture, mix just until combined—about 15-20 strokes. Overmixing develops gluten, which makes your cake tough instead of tender. I learned this the hard way with my first bundt cake disaster.

Skipping the Browning Step

Browning the butter is non-negotiable for that deep, nutty flavor. Cook it over medium heat until it turns golden brown and smells fragrant—about 6-8 minutes. Don’t rush this step or your cake will lack depth. 🔥

Improper Pan Prep

A bundt pan’s intricate design requires thorough greasing. Use 1 tbsp softened butter and 2 tbsp flour to coat every crevice, or the cake will stick. I prefer Baker’s Joy spray for foolproof results.

Caramel Temperature

Cook the caramel to a deep amber color (350°F on a candy thermometer), not light gold. Undercooked caramel will be too thin and runny. If you don’t have a thermometer, test by dropping a bit in cold water—it should form a firm ball.

Rushing the Cooling

Let the cake cool in the pan for exactly 10 minutes before inverting. Too soon and it may break; too long and it’ll stick. Then cool completely before glazing—hot cake will cause the caramel to slide right off. ⏰

Salt Timing

Sprinkle the flaky salt immediately after glazing while the caramel is still sticky. If you wait too long, the salt won’t adhere properly. Use Maldon or another coarse variety for that perfect crunch and visual appeal.
