This cake is perfect for peanut butter lovers who also appreciate the intense, bittersweet taste of dark chocolate.

Ingredients List for Dark Chocolate Peanut Butter Cake

To create this sumptuous cake, you’ll need a list of simple yet indulgent ingredients:

For the Cake:

• 1 ¾ cups all-purpose flour
• ¾ cup unsweetened cocoa powder (preferably dark or Dutch-processed)
• 1 ½ teaspoons baking powder
• 1 ½ teaspoons baking soda
• 1 teaspoon salt
• 2 cups granulated sugar
• 2 large eggs
• 1 cup buttermilk
• ½ cup vegetable oil (or melted coconut oil)
• 2 teaspoons vanilla extract
• 1 cup hot water (or hot coffee for a deeper chocolate flavor)

For the Peanut Butter Frosting:

• 1 cup creamy peanut butter (natural or processed)
• ½ cup unsalted butter, softened
• 3 cups powdered sugar
• 1 teaspoon vanilla extract
• Pinch of salt
• ¼ cup heavy cream (add more for desired consistency)

For the Dark Chocolate Ganache:

• 8 oz dark chocolate (70% cacao or higher)
• 1 cup heavy cream
• 1 tablespoon butter (optional, for added gloss)

Substitutions and Variations

Whether you're catering to dietary restrictions or just want to get creative, there are several ways to customize your Dark Chocolate Peanut Butter Cake. Below are some excellent substitutions and variations:

• Flour: For a gluten-free version, use a 1:1 gluten-free all-purpose flour.
• Sugar: You can substitute granulated sugar with coconut sugar or a sugar substitute like Stevia for a lower glycemic index.
• Eggs: Replace eggs with flaxseed (1 tablespoon flaxseed mixed with 3 tablespoons water = 1 egg) for a vegan version.
• Buttermilk: Substitute buttermilk with dairy-free milk (almond or soy) mixed with 1 tablespoon of vinegar or lemon juice.
• Dark Chocolate: For a less intense chocolate flavor, you can use semi-sweet chocolate instead of dark chocolate in both the cake and ganache.
• Peanut Butter: Use almond or cashew butter as a substitute for peanut butter if you have allergies or want a different flavor profile.

Step-by-Step Cooking Instructions

Making a Dark Chocolate Peanut Butter Cake may seem daunting, but with this simple guide, you'll be on your way to a picture-perfect dessert.

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans. Line the bottoms with parchment paper for easy release.

Step 2: Mix the Dry Ingredients

In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt until thoroughly combined.

Step 3: Mix the Wet Ingredients

In another bowl, whisk together the sugar, eggs, buttermilk, oil, and vanilla extract until smooth and fully incorporated.

Step 4: Combine Wet and Dry Ingredients

Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to over-mix, as this can make the cake tough.

Step 5: Add Hot Water (or Coffee)

Slowly pour in the hot water or coffee while stirring gently. This helps to deepen the chocolate flavor and creates a batter that is smooth and pourable.

Step 6: Bake the Cakes

Divide the batter evenly between the two prepared pans and bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Step 7: Make the Peanut Butter Frosting

In a medium bowl, beat the peanut butter and butter together until smooth and creamy. Gradually add the powdered sugar, one cup at a time, beating well after each addition. Add the vanilla extract and heavy cream, continuing to beat until the frosting reaches your desired consistency.

Step 8: Make the Dark Chocolate Ganache

Place the dark chocolate in a heat-proof bowl. In a small saucepan, heat the heavy cream until it just begins to simmer, then pour it over the chocolate. Let it sit for a minute before whisking until smooth. Stir in the butter for extra shine, if desired.

How to Cook Dark Chocolate Peanut Butter Cake: A Step-by-Step Guide

Once all components are ready, it’s time to assemble and decorate the cake.

Step 1: Level the Cake Layers

If your cakes have domed tops, use a serrated knife to level them off for easy stacking.

Step 2: Frost the First Layer

Place the first cake layer on a serving plate. Spread a generous amount of peanut butter frosting over the top, making sure it's even.

Step 3: Add the Second Layer

Gently place the second cake layer on top of the frosting. Apply a crumb coat (a thin layer of frosting) to lock in any loose crumbs.

Step 4: Apply the Final Frosting Layer

After chilling the cake for 15 minutes to set the crumb coat, apply a thicker layer of peanut butter frosting around the entire cake.

Step 5: Drizzle with Ganache

Once the cake is frosted, drizzle the dark chocolate ganache over the top. Use a spoon or piping bag to create drip edges along the sides for a dramatic finish.

Common Mistakes to Avoid

Baking can be tricky, so here are some common pitfalls to steer clear of:

1. Over-mixing the batter: This can lead to a dense, tough cake. Mix just until the ingredients are combined.
2. Skipping the crumb coat: Without this, your final frosting layer may mix with crumbs and look messy.
3. Rushing the cooling process: Make sure the cakes are fully cooled before frosting, or the frosting will melt and slide off.

Serving and Presentation Tips

A cake as indulgent as this deserves special attention when serving. Here’s how to take your Dark Chocolate Peanut Butter Cake to the next level in terms of presentation and flavor.

How to Serve Dark Chocolate Peanut Butter Cake

For a beautiful and effortless presentation, slice the cake with a warm knife for clean cuts. Serve each slice with a dollop of whipped cream or a scoop of vanilla ice cream to complement the rich flavors.

Presentation Ideas for Dark Chocolate Peanut Butter Cake

• Chocolate Shavings: Garnish the cake with chocolate shavings or curls for added elegance.
• Chopped Peanuts: Sprinkle chopped peanuts on top for a crunchy contrast to the creamy frosting.
• Gold Leaf: For a luxurious touch, use edible gold leaf to decorate the top of the cake.

Dark Chocolate Peanut Butter Cake Recipe Tips

1. Room Temperature Ingredients: Always use room-temperature eggs and butter to ensure the batter mixes evenly.
2. Proper Storage: Store the cake in an airtight container at room temperature for up to three days or refrigerate for up to a week.
3. Freeze for Later: You can freeze the unfrosted cake layers by wrapping them tightly in plastic wrap and foil, then defrost and frost when needed.
