Step-by-Step Instructions
Step 1 — Prepare the Chocolate Cake Layers
Preheat your oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper. In a large bowl, whisk together the dry ingredients: flour, cocoa powder, sugar, baking powder, baking soda, and salt. In another bowl, combine the wet ingredients: buttermilk, oil, eggs, and vanilla. Gradually add the wet mixture to the dry, mixing until just combined. Finally, stir in hot coffee—the batter will be thin.
Divide the batter evenly among the prepared pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes before turning them out onto a wire rack to cool completely.
Step 2 — Make the Salted Caramel Sauce
In a heavy-bottomed saucepan over medium heat, melt granulated sugar, stirring constantly with a heat-resistant spatula until it turns a deep amber color. Carefully whisk in the room-temperature heavy cream—the mixture will bubble vigorously. Remove from heat and stir in the butter and a generous pinch of sea salt until smooth.
Let the caramel cool and thicken at room temperature for at least an hour before using. For a thicker, spreadable consistency, you can refrigerate it for 30 minutes, stirring occasionally.
Step 3 — Whip the Peanut Butter Frosting
Using a stand mixer with the paddle attachment, beat room-temperature unsalted butter and creamy peanut butter on medium speed until completely smooth and fluffy, about 3 minutes. Gradually add sifted powdered sugar, one cup at a time, mixing on low speed to avoid a sugar cloud.
Once incorporated, add vanilla extract and 2-3 tablespoons of heavy cream or milk. Beat on high speed for 2-3 minutes until the frosting is very light, creamy, and holds stiff peaks. If it’s too thick, add more cream a teaspoon at a time.
Step 4 — Level and Assemble the Cake
Once the cake layers are completely cool, use a serrated knife or cake leveler to trim any domed tops so they are flat. Place the first layer on your cake stand or serving plate. Spread a thin, even layer of peanut butter frosting over it, then pipe a dam of frosting around the outer edge.
Spoon about ¼ cup of the cooled salted caramel sauce inside the frosting dam, spreading it gently. Carefully place the second cake layer on top and repeat the process with frosting and caramel. Top with the final cake layer.
Step 5 — Apply the Crumb Coat
Apply a thin layer of peanut butter frosting over the entire cake to trap any loose crumbs. This doesn’t need to be perfect. Use a bench scraper or offset spatula to smooth it as much as possible.
Chill the cake in the refrigerator for at least 20-30 minutes to set the crumb coat firmly. This step is crucial for achieving a clean final layer of frosting.
Step 6 — Frost and Decorate the Final Layer
Remove the chilled cake from the fridge. Apply the remaining peanut butter frosting in a thick, even layer over the crumb coat. Use your spatula and bench scraper to create a smooth finish or intentional swirls.
For a classic drip effect, gently warm the remaining caramel sauce until it’s pourable but not hot. Let it cool slightly, then carefully spoon it around the top edges of the cake, allowing it to drip down the sides. Fill in the center of the top with more caramel.
Step 7 — Chill and Serve
Let the finished Chocolate Peanut Butter Caramel Cake set in the refrigerator for at least one hour before slicing. This allows the frosting to firm up and the flavors to meld, resulting in cleaner slices.
For the best texture and taste, let the cake sit at room temperature for 20-30 minutes before serving. Use a sharp knife dipped in hot water and wiped dry for perfectly clean cuts through the caramel and frosting layers.

Healthier Alternatives
This decadent Chocolate Peanut Butter Caramel Cake can be adapted to fit various dietary needs without sacrificing its signature flavor. Here are practical ingredient swaps to consider.
- Protein-Packed Flour — Replace half the all-purpose flour with almond flour or a scoop of unflavored protein powder for a richer texture and a protein boost.
- Lower-Carb Sweetener — Swap granulated sugar in the cake and caramel for a monk fruit-erythritol blend to significantly reduce the net carbs while maintaining sweetness.
- Dairy-Free Delight — Use coconut oil or vegan butter and full-fat coconut milk to create a lush, dairy-free chocolate peanut butter caramel cake that remains incredibly creamy.
- Gluten-Free Base — A 1:1 gluten-free baking flour blend works perfectly as a direct substitute for all-purpose flour, ensuring the cake stays tender.
- Natural Nut Butter — Opt for natural, unsweetened peanut butter (or almond butter) to control added sugars and oils, enhancing the pure nutty flavor.
- Low-Sodium Option — Use unsalted butter and a no-salt-added peanut butter. You can often reduce added salt in the cake batter by half without affecting the structure.
- Lighter Caramel — For the caramel layer, consider a date-based caramel or a sauce made with coconut milk and a sugar alternative for a more nutrient-dense filling.
- Greek Yogurt Frosting — Mix Greek yogurt with a little peanut butter powder and sweetener for a tangy, high-protein frosting alternative to traditional buttercream.

Serving Suggestions
- Pair with a cold glass of milk, a scoop of vanilla bean ice cream, or a rich cup of coffee to balance the decadent sweetness.
- Perfect for celebrations like birthdays, anniversaries, or as a show-stopping finale to a dinner party.
- For an elegant touch, garnish each slice with a drizzle of extra salted caramel sauce, a sprinkle of flaky sea salt, and crushed roasted peanuts.
- Serve slightly chilled to firm up the layers, or at room temperature for a softer, gooier texture.
- Use a warm, clean knife for slicing to achieve neat, beautiful pieces that showcase all the layers.
- Transform leftovers into a next-day treat by crumbling a slice over vanilla ice cream for an epic sundae.
This Chocolate Peanut Butter Caramel Cake is a true crowd-pleaser. Its combination of flavors and textures makes it versatile enough for both casual gatherings and formal occasions, ensuring every slice is a memorable experience.
Common Mistakes to Avoid
- Mistake: Using cold ingredients for the cake batter. Fix: Bring eggs, milk, and butter to room temperature to ensure a smooth, well-emulsified batter for an even crumb.
- Mistake: Overmixing the cake batter after adding dry ingredients. Fix: Mix just until the flour disappears to avoid developing gluten, which leads to a tough, dense cake.
- Mistake: Not properly preparing cake pans. Fix: Always line pans with parchment paper and grease the sides to guarantee your Chocolate Peanut Butter Caramel Cake layers release cleanly.
- Mistake: Under-baking or over-baking the cake layers. Fix: Use a toothpick test in the center; it should come out with a few moist crumbs, not wet batter or completely clean.
- Mistake: Assembling the cake with warm layers. Fix: Cool layers completely on a wire rack to prevent the frosting and caramel from melting and sliding off.
- Mistake: Using a runny peanut butter frosting. Fix: Ensure your butter is properly softened, not melted, and use a thick, no-stir peanut butter for stable, pipeable frosting.
- Mistake: Pouring hot caramel directly onto the cake. Fix: Allow the caramel sauce to cool and thicken slightly so it drapes over the layers instead of soaking straight through.
- Mistake: Skipping the crumb coat. Fix: Apply a thin layer of frosting to seal in crumbs before the final coat for a sleek, professional finish on your layered cake.
- Mistake: Not salting the caramel. Fix: A pinch of flaky sea salt in the caramel enhances all the flavors, cutting the sweetness and highlighting the chocolate and peanut butter.
- Mistake: Serving the cake immediately from the fridge. Fix: Let the chilled cake sit at room temperature for 30-60 minutes before slicing for the softest texture and fullest flavor.
Storing Tips
- Fridge: Store your Chocolate Peanut Butter Caramel Cake in an airtight container in the refrigerator for up to 5 days. This keeps the caramel and frosting stable and prevents the cake from drying out.
- Freezer: For longer storage, wrap the whole cake or individual slices tightly in plastic wrap and then in foil. Freeze for up to 3 months. Thaw overnight in the fridge before serving.
- Reheat: For a warm, gooey slice, microwave a single portion on medium power for 15-20 seconds. Ensure the internal temperature reaches at least 165°F (74°C) for food safety if the cake contains any dairy-based components like cream cheese frosting.
Always let the cake cool completely before storing to prevent condensation, which can make the layers soggy.
