Step‑by‑Step Instructions for Caramel Coffee Buttercream Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, take three 9-inch round cake pans and generously grease and flour their interiors to prevent sticking. You’ll want to see the shimmer of the flour against the butter, ensuring they are ready to receive the rich batter of your Caramel Coffee Buttercream Cake.
Step 2: Mix the Dry Ingredients
In a medium-sized bowl, whisk together 2 ½ cups of all-purpose flour, 2 ½ teaspoons of baking powder, ½ teaspoon of baking soda, and ½ teaspoon of salt. This step creates the foundation for your cake, ensuring a light and fluffy texture. Once thoroughly combined, set this mixture aside, allowing the leavening agents to develop their magic as you move on to the next steps.
Step 3: Cream Butter and Sugar
In a large mixing bowl, combine 1 cup of softened unsalted butter with 2 cups of granulated sugar. Using a handheld mixer or stand mixer, cream these ingredients together on medium speed for about 3-5 minutes, until the mixture becomes light and fluffy. You’ll know it’s ready when it appears pale and airy, creating the perfect base for your moist cake.
Step 4: Incorporate Eggs and Vanilla
Add in 4 large eggs, one at a time, ensuring each egg is fully incorporated before adding the next. Follow this by mixing in 1 teaspoon of vanilla extract until the batter is smooth and cohesive, showcasing its rich flavor. This process enriches the Caramel Coffee Buttercream Cake, contributing to its delightful taste and soft texture.
Step 5: Combine Wet and Dry Ingredients
Gradually add the reserved flour mixture to the butter mixture, alternating with 1 cup of buttermilk and ½ cup of cooled strong brewed coffee. Start and end with the flour mixture, mixing until just combined to avoid overworking the batter. You want it to be thick yet pourable, showcasing the perfect blend of flavors for your cake.
Step 6: Divide and Prepare for Baking
Evenly divide the rich batter among the three prepared cake pans. Use a spatula to smooth the tops, ensuring they are level, so your layers bake uniformly. Visualize the wonderful layers of the Caramel Coffee Buttercream Cake stacking up, and get ready to pop them into the oven.
Step 7: Bake the Cakes
Place the filled cake pans in your preheated oven and bake for 25-30 minutes. To check for doneness, insert a toothpick in the center—if it comes out clean, your cakes are ready. Once baked, allow them to cool in the pans for 10 minutes before carefully transferring them to a wire rack for full cooling.
Step 8: Make the Caramel Sauce
While the cakes cool, prepare the caramel sauce. In a medium saucepan over medium heat, add 1 cup of granulated sugar. Stir constantly with a wooden spoon until the sugar melts and reaches a golden amber color, about 5-7 minutes. This sweet sauce enhances the flavors in your Caramel Coffee Buttercream Cake and adds that enticing finish.
Step 9: Combine Butter and Cream for Caramel
Once the sugar is melted, stir in 6 tablespoons of unsalted butter until fully combined. Gradually pour in ½ cup of heavy cream while stirring continuously to achieve a smooth sauce. Finally, mix in 1 teaspoon of vanilla extract and a pinch of salt. Allow it to cool slightly before using, as it will thicken as it cools.
Step 10: Prepare the Buttercream Frosting
In a large mixing bowl, beat 1 cup of softened unsalted butter until creamy, which should take about 2-3 minutes. Gradually add 4 cups of powdered sugar on low speed until blended, ensuring there's no cloud of sugar. The frosting should appear fluffy and light, forming the ideal topping for your beautiful cake.
Step 11: Finish the Buttercream
Add in ¼ cup of heavy cream, 2 tablespoons of the caramel sauce you just made, 1 teaspoon of vanilla extract, and 1 tablespoon of cooled strong brewed coffee. Beat on medium speed until the mixture is fully combined, velvety, and fluffy. This buttercream will bring the final touch of indulgence to your Caramel Coffee Buttercream Cake.
Step 12: Assemble Your Cake
To assemble the cake, place one cooled layer on a serving plate and spread a generous layer of buttercream frosting on top. Repeat this process with the second layer, then gently stack the third layer on top. Frost the top and sides of the cake with the remaining buttercream, resulting in a beautifully decadent dessert that is sure to impress.

Expert Tips for Caramel Coffee Buttercream Cake
-
Room Temperature Ingredients: Use ingredients like butter and eggs at room temperature for a smooth batter and even baking. It ensures better emulsification and texture in the Caramel Coffee Buttercream Cake.
-
Avoid Overmixing: Mix the batter until just combined to prevent a dense cake. Overmixing can lead to gluten formation, making the cake chewy instead of moist and tender.
-
Check for Doneness: Always use a toothpick to test for doneness; it should come out clean or with a few moist crumbs. This avoids underbaking or overbaking your layers.
-
Cooling Cakes: Allow the cake layers to cool in the pans for just 10 minutes before transferring them to a wire rack. This helps prevent them from breaking apart while still being warm enough for easy removal.
-
Making Caramel Sauce: Stir constantly while melting sugar for caramel to prevent burning. If it does burn, you'll need to start over for a perfect sauce.
-
Frosting Consistency: If your buttercream is too thick, add more heavy cream to reach the desired spreadability. A perfect consistency will make it easy to work with while frosting your Caramel Coffee Buttercream Cake.
