  • Baking Powder: Helps cake rise and creates fluffy, light crumb.
  • Baking Soda: Balances acidity and enhances browning.
  • Salt: Amplifies overall flavor and balances sweetness.
For Moisture and Binding:
  • Granulated Sugar, Brown Sugar: Creates sweetness and helps retain moisture.
  • Eggs: Binds ingredients and adds richness.
  • Vegetable Oil: Ensures cake remains tender and moist.
  • Vanilla Extract: Adds depth and enhances chocolate flavor.
  • Buttermilk: Provides tanginess and helps activate baking soda.
For Liquid and Depth:
  • Hot Coffee or Water: Intensifies chocolate flavor and creates smooth batter texture.

Tools That Help Layer This Dessert Like a Pro

  • Large mixing bowls: Essential for combining dry and wet ingredients separately.
  • Whisk: Perfect for smoothly blending flour, cocoa, and other dry ingredients.
  • Electric mixer or hand mixer: Great for creaming sugars and mixing wet ingredients efficiently.
  • 9-inch cake pans: Exactly the right size for creating two cake layers.
  • Parchment paper: Helps line cake pans for easy cake removal.
  • Toothpick or cake tester: Crucial for checking cake doneness.
  • Cooling rack: Allows cakes to cool evenly and quickly.
  • Offset spatula: Ideal for spreading frosting smoothly between cake layers.

How to Make Peanut Butter and Chocolate Cake That Stuns

  • Warm Up the Oven

Crank your oven to a toasty 350°F and give your cake pans a quick spray and parchment paper hug.

  • Create the Dry Magic

Grab a big bowl and whisk together the powdery ingredients, blending them into a rich chocolate canvas.

  • Mix the Wet Wonders

In another bowl, dance together the sugars, eggs, oil, vanilla, and buttermilk until they become best friends.

  • Marry the Mixtures

Gently fold the wet and dry ingredients, then splash in some hot coffee to create a silky smooth batter that’ll make your taste buds do a happy dance.

  • Bake to Perfection

Pour the batter into your prepared pans and slide them into the oven. Let them bake for 30-35 minutes, or until a toothpick comes out clean and your kitchen smells like chocolate heaven.

  • Cool and Calm

Take the cakes out and let them chill completely before you start decorating – patience is key to cake magic!

Add Crunch or Salt for a Bold Flavor Hit

  • Cake Cooling Hack: Allow cakes to cool in pans for 10 minutes, then transfer to wire racks to prevent soggy bottoms and ensure perfect texture.
  • Make-Ahead Magic: Bake cake layers a day in advance and wrap tightly in plastic wrap to intensify moisture and flavors before frosting.
  • Gluten-Free Option: Swap regular flour with a gluten-free all-purpose blend, adding xanthan gum for better structure and texture.
  • Dairy-Free Twist: Replace buttermilk with almond milk mixed with apple cider vinegar, and use dairy-free chocolate for a lactose-free version of this decadent cake.
  • Decoration Pro Tips: Use a rotating cake stand for smooth frosting, and create beautiful chocolate drips by letting ganache cool slightly before pouring over the cake layers.

Serve With a Glass of Milk or a Spoon

  • Decadent Dessert Companions: Peanut Butter Chocolate Layer Cake Serving Suggestions
  • Creamy Milk Pairing: Serve each slice with a cold glass of whole milk to balance the rich chocolate and peanut butter flavors, creating a classic dessert experience.
  • Elegant Garnish Touch: Sprinkle chopped roasted peanuts or chocolate shavings on top of each slice for added texture and visual appeal that elevates the cake's presentation.
  • Ice Cream Dream: Add a scoop of vanilla or chocolate ice cream alongside the cake slice to create a delightful temperature contrast and enhance the dessert's indulgent profile.
  • Coffee Companion: Offer a freshly brewed espresso or cappuccino to complement the cake's deep chocolate notes and provide a sophisticated finishing touch to the dessert course.

Store With Care to Keep It Moist and Rich

  • Refrigerator Storage Strategy: Keep cake covered in an airtight container for up to 5 days. Wrap individual slices in plastic wrap to maintain moisture and prevent flavor absorption from other foods.
  • Room Temperature Freshness: Store cake at cool room temperature for 2-3 days if serving within a short period. Place under a cake dome or cover with loose plastic wrap to prevent drying out.
  • Freezing for Future Enjoyment: Slice cake into portions and wrap tightly in plastic wrap, then aluminum foil. Freeze up to 3 months for quick dessert options. Thaw overnight in refrigerator before serving to retain texture and taste.
  • Make-Ahead Magic: Prepare cake layers in advance and store separately from frosting. Wrap cooled layers in plastic wrap and refrigerate for 2 days or freeze for longer storage. This technique helps maintain cake's moisture and simplifies final assembly.

  • ¾ cup (75 g) unsweetened cocoa powder
  • 2 tsps baking powder
  • 1 tsp baking soda
  • ½ tsp salt
  • ½ cup (120 ml) vegetable oil
  • 1 tsp vanilla extract
  • 1 cup (240 ml) buttermilk (or milk + 1 tsp vinegar)
  • ½ cup (120 ml) hot coffee or hot water
  • 1 cup (225 g) unsalted butter, softened
  • 1 cup (250 g) creamy peanut butter
  • 3 cups (360 g) powdered sugar

  • ¼ cup (60 ml) heavy cream or milk
  • 1 tsp vanilla extract
  • ½ cup (120 ml) heavy cream
  • ½ cup (85 g) semi-sweet chocolate chips
  • 1 tsp butter (for extra shine)

Instructions

  1. Oven Preparation: Preheat the oven to 350°F (175°C) and meticulously line two 9-inch cake pans with parchment paper, ensuring thorough greasing to prevent sticking.
  2. Dry Ingredient Fusion: In a spacious mixing bowl, whisk cocoa powder, flour, baking powder, baking soda, and salt until achieving a uniform, lump-free powder blend that promises a velvety cake texture.
  3. Wet Ingredient Amalgamation: Create a silky mixture by combining sugars, eggs, vegetable oil, vanilla extract, and buttermilk in a separate bowl, whisking until the composition reaches a smooth, glossy consistency.
  4. Batter Integration: Delicately fold the liquid ingredients into the dry mixture, stirring methodically to prevent clumping and create a luxurious chocolate batter with a satiny finish.
  5. Liquid Enhancement: Incorporate hot coffee or water, stirring until the batter transforms into a rich, glossy chocolate canvas with deep, complex flavor undertones.
  6. Baking Process: Distribute the batter evenly between prepared pans, smoothing the surfaces, then bake for 30-35 minutes until a toothpick inserted centrally emerges clean, indicating perfect doneness.
  7. Cooling and Preparation: Remove cakes from the oven and transfer to wire racks, allowing complete cooling to room temperature, which stabilizes the cake’s structure and prepares it for frosting and layering.

Notes

  • Temperature Precision: Use an accurate oven thermometer to ensure exact 350°F for consistent cake texture and even baking.
  • Mixing Technique: Fold wet and dry ingredients gently to prevent overmixing, which can lead to dense, tough cake layers.
  • Coffee Enhancement: Use freshly brewed hot coffee to intensify chocolate flavor and create deeper, more complex cake moisture.
  • Room Temperature Ingredients: Bring eggs, buttermilk, and other liquid ingredients to room temperature for smoother batter integration and better cake rise.
