Why This Decadent Caramel Cake with Homemade Caramel and Fluffy Vanilla Buttercream Recipe Works

This recipe shines because it masterfully combines technique and quality ingredients that elevate the simplest elements into something extraordinary. The secret lies in heating sugar slowly and patiently to create a golden homemade caramel that is rich and creamy without bitterness. Meanwhile, the combination of butter and oil in the cake batter keeps the crumb irresistibly moist and tender, while the careful alternating of dry ingredients and buttermilk ensures the perfect soft yet sturdy texture. Lastly, the buttercream’s silky fluffiness balances the caramel’s blissful sweetness, delivering a perfect textural harmony that will keep everyone reaching for seconds.

Ingredients You’ll Need

You don’t need a dozen fancy ingredients for this cake, just a handful of simple, quality staples that come together beautifully to impress and satisfy every bite.

• Sugar: The foundation for that gorgeous homemade caramel.
• Butter: Adds richness both in the cake and the caramel.
• Heavy cream: Creates the luxurious texture in the caramel sauce.
• Salt: Balances the sweetness with a touch of savory depth.
• Oil: Works alongside butter for a moist, tender cake crumb.
• Eggs: Provide structure and lift to the cake layers.
• Vanilla extract: Infuses warmth and aromatic sweetness.
• Cake flour: Ensures the lightest, fluffiest crumb possible.
• Baking powder: Leavens the cake for a perfect rise.
• Buttermilk: Adds tang and moisture, enhancing flavor complexity.
• Powdered sugar: For that melt-in-your-mouth silky buttercream.
• Whole milk: Lightens the buttercream to fluffy perfection.

Ingredient Substitutions & Tips

• Butter: You can use European-style butter for a richer taste, or substitute with a plant-based butter to keep it dairy-free.
• Heavy cream: Coconut cream can be a dairy-free alternative for the caramel, but it will slightly alter the flavor.
• Buttermilk: If you don’t have buttermilk on hand, add 1 tablespoon of lemon juice or white vinegar to a cup of whole milk and let it sit for 5 minutes.
• Cake flour: Substitute with a mix of all-purpose flour and cornstarch (1 cup minus 2 tablespoons all-purpose flour plus 2 tablespoons cornstarch) for a lighter texture when cake flour is unavailable.

How to Make Decadent Caramel Cake with Homemade Caramel and Fluffy Vanilla Buttercream Recipe

Step 1: Crafting the Homemade Caramel

Start by heating 2 cups of sugar in a heavy-bottomed saucepan over medium-low heat. Watch carefully as the sugar clumps and then melts into a golden amber liquid. Swirl the pan gently every 20 seconds to avoid burning. Once fully melted, immediately whisk in 3/4 cup of room temperature butter—the mixture will bubble vigorously, a good sign! Next, slowly stir in 2/3 cup heavy cream and 2 teaspoons salt until smooth. Pour into a container and let it cool completely, ideally a day ahead, so your caramel is set and ready to shine in the layers.

💡 Pro Tip: Avoid stirring sugar initially; just swirl the pan gently for an even melt.

Step 2: Preparing the Cake Batter

Preheat your oven to 325°F and prepare three 6-inch pans with a light greasing and dusting of flour. In a large bowl, beat together 1/2 cup softened butter and 1/2 cup oil for about 3 minutes, until smooth and combined. Gradually add 1 1/2 cups sugar and beat on high until light and fluffy—this aerates your batter beautifully. Add 4 room temperature eggs one by one, scraping the bowl each time to ensure full incorporation. Blend in 2 tablespoons vanilla extract and continue beating on high to build a sturdy yet tender crumb.

💡 Pro Tip: Mixing butter and oil gives a moist texture without sacrificing richness.

Step 3: Combining Dry Ingredients and Buttermilk

In a separate bowl, sift together 3 cups cake flour, 1 teaspoon salt, and 2 1/2 teaspoons baking powder. Alternate adding your dry mixture and 1 1/3 cups buttermilk to the wet ingredients in four batches, beginning and ending with dry ingredients. Stir gently—some lumps are fine, so don’t overwork your batter. Divide evenly into your prepared pans and bake for 30 minutes or until golden and springy to the touch. Cool completely before moving to frosting.

💡 Pro Tip: Alternating dry and wet ingredients keeps the batter balanced and tender.

Step 4: Whipping Up the Fluffy Vanilla Buttercream

In your stand mixer with the whisk attachment, combine 1 cup softened unsalted butter and 1.5 pounds powdered sugar. Beat until thick and creamy, then add 4 tablespoons whole milk, 1 tablespoon vanilla extract, and 1/2 teaspoon salt. Beat on high for several minutes, scraping down the bowl once or twice until the frosting is gloriously thick, airy, and fluffy—perfect for spreading and piping.

💡 Pro Tip: Using a whisk attachment and beating long ensures maximum fluffiness in your frosting.

Step 5: Assembling the Decadent Caramel Cake

Bring your cooled caramel to room temperature. Set aside about half a cup for decorating the cake’s exterior. Place the first cake layer on your stand and pipe a buttercream border around the edge to hold in the luscious caramel filling—this small detail keeps your cake neat and gooey inside. Pour half of the caramel onto the cake and spread evenly within the border. Add the second layer and repeat the filling step, then top with the final cake layer. Frost the entire cake with your vanilla buttercream, then use the reserved caramel to swirl and dab along the sides and top, like an artist’s palette, adding visual intrigue and extra decadence. Chill until ready to enjoy.

💡 Pro Tip: The buttercream barrier keeps the caramel from dripping and keeps your layers clean and defined.

Common Mistakes to Avoid

Learn from these common pitfalls:

• Burning the caramel: High heat or impatient stirring can cause it to scorch, turning bitter.
• Using cold butter or eggs: This prevents the batter from emulsifying properly, leading to dense layers.
• Overmixing batter: Can develop gluten and make the cake tough instead of tender.
• Skipping cake pans preparation: May cause your cake layers to stick and break.
• Frosting warm cake: Leads to melted buttercream and a messy finish.
• Not chilling caramel before assembly: Makes it runny and difficult to handle during layering.

FAQs

Can I make the caramel sauce ahead of time?

Absolutely! Making the caramel at least a day in advance allows it to cool and thicken to the perfect consistency for layering and decorating.

What if my caramel crystallizes?

If sugar crystals form, gently reheat the caramel and stir carefully. Avoid stirring once it starts melting to prevent recrystallization.

Can I use regular all-purpose flour instead of cake flour?

Yes, but the texture will be slightly denser. Sifting the flour well and adding cornstarch can help mimic cake flour’s lightness.

Is there a dairy-free option for this recipe?

Yes! Substitute butter with plant-based margarine and heavy cream with coconut cream, but be aware the flavor and texture may vary slightly.

How long does the cake stay fresh?

Stored in the refrigerator, this cake stays fresh up to 4 days. The flavors actually deepen and meld beautifully after a day.

Can I double this recipe for a larger cake?

Yes, just double all ingredients and bake in appropriate sized pans, increasing baking time and checking for doneness.

What is the best way to level cake layers?

Use a serrated knife or cake leveler to trim domed tops for even stacking and a professional look.

Can I prepare this cake without a stand mixer?

Yes! Use a hand mixer or whisk vigorously by hand, but it will take more effort to achieve the light, fluffy texture.
