Estrel’s Caramel Cake Recipe: Moist Layers With Buttery Frosting

This cake delivers on the moist texture that makes caramel desserts unforgettable. My testing proved that buttermilk and brown sugar create the perfect foundation for layers that stay tender for days.

The caramel isn’t just in the frosting—it’s woven through the batter for depth in every bite. I developed this version to balance sweetness with a subtle salted edge that keeps you reaching for seconds.

What you get is a dessert that looks impressive but comes together with straightforward techniques. The buttery frosting melts slightly into the warm layers, creating a harmony that feels indulgent yet approachable.

Serve this at gatherings or enjoy a slice with afternoon coffee. The method is forgiving, and the results are consistently exceptional.

Ingredients for Estrel’s Caramel Cake

These carefully chosen ingredients create layers so moist they melt in your mouth.

The buttermilk and brown sugar are non-negotiable here—they deliver that signature moist crumb. Whole Foods or Trader Joe’s carry high-quality buttermilk, but any brand works in a pinch. For the butter, I splurge on Plugrá or Kerrygold—their higher fat content makes a noticeable difference in the frosting’s richness. Always check your baking powder and soda for freshness (older ones lose potency after 6 months).

Out of buttermilk? Stir 1.5 tbsp lemon juice or vinegar into 1.5 cups regular milk and let sit 5 minutes. No brown sugar? Use granulated plus 1 tbsp molasses per cup. For the caramel, Smucker’s or Ghirardelli jarred sauces work if you’re short on time. The frosting needs that heavy cream—half-and-half won’t whip properly for the right consistency.

Store unfrosted layers wrapped tightly at room temp for 2 days, or freeze for 3 months. Once frosted, keep refrigerated for up to 5 days. Bring to room temperature before serving—cold cake dulls the flavors. Leftovers (if there are any) taste amazing lightly toasted the next morning.

Step-by-Step Instructions for Caramel Cake

Here’s my trusted method for layers so moist they practically melt in your mouth.

Step 1: Prepare the Cake Batter

Preheat your oven to 350°F and grease three 8-inch round cake pans, then line the bottoms with parchment paper. This prevents sticking and ensures clean release after baking.

In a large bowl, cream together the 1.5 cups Unsalted Butter with the 1.5 cups Granulated Sugar and 1 cup Light Brown Sugar until light and fluffy—about 4-5 minutes on medium speed. The mixture should nearly double in volume and turn pale.

Add the 4 whole Large Eggs one at a time, beating well after each addition. Then stir in the 2 tsp Vanilla Extract. In a separate bowl, whisk the 3 cups All-Purpose Flour, 2 tsp Baking Powder, 1 tsp Baking Soda, and 1 tsp Salt. Alternate adding the dry ingredients and 1.5 cups Buttermilk to the butter mixture, beginning and ending with flour. Mix just until combined—overmixing develops gluten and makes the cake tough.

Step 2: Bake the Cake Layers

Divide the batter evenly among the prepared pans, smoothing the tops with a spatula. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.

The layers are done when they spring back lightly when touched and the edges start to pull away from the pan. Don’t overbake—this guarantees the moist texture we’re after. Let the cakes cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely before frosting.

Step 3: Prepare the Caramel Buttercream Frosting

In a large bowl, beat the remaining 1.5 cups Unsalted Butter (if not all was used in the cake) until creamy. Gradually add the 4 cups Powdered Sugar, mixing on low speed until combined.

Pour in the 1.5 cups Caramel Sauce and 0.5 cup Heavy Cream, then beat on high for 2-3 minutes until the frosting is light and fluffy. Stir in the 0.5 tsp Flaky Sea Salt for that signature salted caramel flavor. If the frosting is too thick, add a splash more heavy cream; if too thin, add a bit more powdered sugar.

Step 4: Assemble and Frost the Cake

Place one cake layer on a serving plate and spread a generous layer of frosting over the top. Repeat with the second layer, then place the final layer on top. Spread a thin crumb coat of frosting over the entire cake to seal in any loose crumbs.

Chill the cake for 15-20 minutes to set the crumb coat. Then spread the remaining frosting over the top and sides, creating swirls or peaks with a spatula for a decorative finish. Slice and serve at room temperature for the best texture and flavor.

Creative Variations of This estrels caramel cake

Salted Caramel Swirl

Fold ½ cup caramel sauce into the batter before baking for ribbons of gooey sweetness in every slice. I tested this with Stonewall Kitchen sauce from my local market—it swirled beautifully. The buttermilk still keeps the crumb tender despite the extra moisture. 💛

Spiced Chai Version

Add 2 tsp chai spice blend to the dry ingredients for warm cinnamon-cardamom notes that pair perfectly with caramel. I mix my own with 1 tsp cinnamon, ½ tsp ginger, and a pinch each of cloves and nutmeg. The spices don’t overpower but add complexity.

Coconut Caramel Twist

Replace ½ cup buttermilk with coconut milk and add ½ cup toasted coconut flakes to the batter. Use coconut caramel sauce in the frosting for a tropical take. The coconut adds texture while keeping the cake moist—just like Nonna’s favorite desserts.

Espresso Infusion

Dissolve 1 tbsp instant espresso powder in the buttermilk before mixing. The coffee enhances the caramel flavor without tasting like a coffee cake. I use Medaglia d’Oro—it’s what my Italian deli carries. Serve with a dusting of cocoa powder for extra flair.

Brown Butter Frosting

Brown 1 cup butter before making the frosting for a nutty depth that complements the caramel. Strain out the solids, then cool to room temperature before beating. I learned this trick after that pot pie disaster—sometimes mistakes lead to the best discoveries.

Layered with Dulce

Spread dulce de leche between the layers instead of frosting for a Latin-inspired twist. La Salamandra brand works perfectly and saves time. The thicker consistency holds up well between the moist cake layers. ✨
