Ingredients List

    • 2 cups all-purpose flour
    • 2 cups granulated sugar
    • ¾ cup unsweetened cocoa powder
    • 2 teaspoons baking soda
    • 1 teaspoon baking powder
    • 1 teaspoon salt
    • 2 large eggs, room temperature
    • 1 cup whole milk
    • ½ cup vegetable oil
    • 2 teaspoons vanilla extract
    • 1 cup hot brewed coffee

For the Peanut Butter Frosting:

    • 1 cup creamy peanut butter
    • ½ cup unsalted butter, softened
    • 3 cups powdered sugar
    • ⅓ cup heavy cream
    • 1 teaspoon vanilla extract
    • Optional: ¼ cup mini chocolate chips for garnish
    • Optional: Chopped peanuts for topping

Timing / Cooking Schedule

Prep time: 20 minutes

Cooking time: 35 minutes

Total time: 55 minutes (plus 1 hour cooling)

This timeline doesn't include frosting application, which takes about 15 additional minutes. Plan ahead by baking the cake layers the night before your event for stress-free assembly.

Step-by-Step Instructions

Step 1: Preheat your oven to 350°F (175°C) and prepare two 9-inch round cake pans by greasing them with butter and lining the bottoms with parchment paper. This prevents sticking and ensures easy removal.

Step 2: In a large mixing bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt until evenly combined. Sifting the cocoa powder prevents lumps and creates a smoother batter.

Step 3: Add eggs, milk, oil, and vanilla to the dry ingredients. Beat on medium speed for 2 minutes until well incorporated. The mixture will be thick at this stage—that's perfectly normal.

Step 4: Carefully stir in the hot coffee. Your batter will become thin and liquidy, but this is what creates the incredibly moist texture. Coffee enhances the chocolate flavor without adding a coffee taste.

Step 5: Divide the batter evenly between prepared pans and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Rotate pans halfway through for even baking.

Step 6: Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely. Frosting warm cake will cause melting and sliding.

Step 7: For the frosting, beat peanut butter and butter together until creamy. Gradually add powdered sugar, alternating with heavy cream, until you achieve a spreadable consistency. When assembling your chocolate peanut butter cake recipe, spread frosting between layers, then cover the top and sides generously.

Tips, Variations, or Cooking Advice

Dietary Modifications: For a gluten-free version, substitute with a 1:1 gluten-free flour blend. Make it dairy-free by using almond milk and coconut oil instead of dairy products, and choose a plant-based butter alternative for frosting.

Flavor Variations: Add a tablespoon of espresso powder to intensify chocolate flavor, or swirl in chocolate chips throughout the batter. For extra peanut butter punch, add peanut butter chips between layers.

Meal Prep: This cake freezes beautifully! Wrap unfrosted layers tightly in plastic wrap and aluminum foil, then freeze for up to 3 months. Thaw overnight in the refrigerator before frosting.

Beginner Tips: Room temperature ingredients blend more smoothly, creating better texture. Don't overmix after adding coffee—gentle folding is sufficient.

Common Mistakes to Avoid

Mistake 1: Skipping the parchment paper liner. Solution: Always line pans to prevent sticking, especially with chocolate cakes that tend to be more delicate.

Mistake 2: Overmixing the batter after adding liquids. Solution: Mix just until ingredients are combined to avoid developing too much gluten, which creates a dense, tough cake.

Mistake 3: Frosting warm cake layers. Solution: Patience pays off—completely cooled cakes prevent frosting from melting and sliding off.

Mistake 4: Using cold ingredients straight from the refrigerator. Solution: Let eggs, milk, and butter sit at room temperature for 30 minutes before starting for optimal texture.

Mistake 5: Opening the oven door too frequently. Solution: Check doneness only after the minimum baking time to maintain consistent temperature.

Storage / Leftovers Tips

Store your finished chocolate peanut butter cake recipe covered at room temperature for up to 2 days, or refrigerate for up to 5 days in an airtight container. The frosting contains dairy, so refrigeration is recommended in warm climates. Before serving refrigerated cake, let it sit at room temperature for 30 minutes to restore moisture and soften the frosting. For longer storage, freeze individual slices wrapped in plastic wrap and placed in freezer bags for up to 3 months. Thaw frozen slices in the refrigerator overnight, then bring to room temperature. The amazing chocolate peanut butter cake recipe maintains its incredible texture and flavor when properly stored, making it perfect for advance preparation. Avoid storing near strong-smelling foods, as the cake can absorb odors.
