What is Chocolate Peanut Butter Cake?

A Chocolate Peanut Butter Cake is a layered dessert that combines two of the most beloved flavors in baking: chocolate and peanut butter. This cake typically features moist chocolate cake layers filled and frosted with a creamy peanut butter frosting. To top it all off, many versions include a luscious chocolate ganache, peanut butter cups, or other peanut-flavored decorations to add a crunchy, sweet, and salty finish. It’s a dessert that appeals to anyone who enjoys the rich and decadent fusion of chocolate and peanut butter.

Ingredients List for Chocolate Peanut Butter Cake

Here’s a breakdown of everything you’ll need to create a perfectly rich Chocolate Peanut Butter Cake:

For the Chocolate Cake Layers:

• 2 cups all-purpose flour
• 2 cups granulated sugar
• ¾ cup unsweetened cocoa powder
• 2 teaspoons baking powder
• 1½ teaspoons baking soda
• 1 teaspoon salt
• 1 cup whole milk
• ½ cup vegetable oil
• 2 large eggs
• 2 teaspoons vanilla extract
• 1 cup boiling water (this helps create a moist, rich texture)

For the Peanut Butter Frosting:

• 1 cup creamy peanut butter (smooth, not chunky)
• ½ cup unsalted butter, softened
• 3 cups powdered sugar
• ½ cup heavy cream (you may need a little more if the frosting is too thick)
• 2 teaspoons vanilla extract
• A pinch of salt (optional, to balance sweetness)

For the Chocolate Ganache (Optional but Recommended):

• 1 cup semi-sweet chocolate chips
• ½ cup heavy cream

Substitutions and Variations

Baking is both a science and an art, and while it’s important to follow some key guidelines, you can still add your personal touch to this recipe. Here are a few substitutions and variations you can try:

• Flour Alternatives: If you prefer a gluten-free version, substitute the all-purpose flour with a 1-to-1 gluten-free baking flour.
• Dairy-Free: Use almond milk or coconut milk in place of whole milk. For the frosting and ganache, you can substitute dairy-free butter and cream options like coconut cream or vegan butter.
• Sweetener Substitutes: Try using coconut sugar or a natural sweetener like monk fruit to reduce the sugar content in the cake, though this may affect the flavor slightly.
• Nut-Free Variation: For those with nut allergies, consider using sunflower seed butter or a similar nut-free alternative in place of peanut butter. The texture will stay creamy, but the flavor will shift.
• Additional Mix-Ins: Add chocolate chips or crushed peanuts to the cake batter for extra texture and flavor!

Step-by-Step Cooking Instructions

Now that you have your ingredients ready, it’s time to start baking! Follow these step-by-step instructions to achieve a perfectly moist Chocolate Peanut Butter Cake.

Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line them with parchment paper to ensure easy release after baking.

Step 2: Mix Dry Ingredients

In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. This will ensure all your dry ingredients are evenly distributed.

Step 3: Combine Wet Ingredients

In a separate bowl, beat the eggs, milk, vegetable oil, and vanilla extract together until fully combined. Gradually add the wet ingredients to the dry ingredients, mixing on medium speed until just combined.

Step 4: Add Boiling Water

Slowly pour in the boiling water, mixing continuously. The batter will appear thin, but don’t worry—this is what helps create a moist, tender cake. Pour the batter evenly between the two prepared pans.

Step 5: Bake the Cake Layers

Place the pans in the preheated oven and bake for 30–35 minutes or until a toothpick inserted into the center comes out clean. Once done, allow the cakes to cool in the pans for 10 minutes before transferring them to wire racks to cool completely.

How to Make the Peanut Butter Frosting

Step 1: Cream the Butter and Peanut Butter

In a large bowl, beat together the softened butter and peanut butter until smooth and creamy.

Step 2: Add the Powdered Sugar

Gradually add the powdered sugar, one cup at a time, mixing well after each addition. If the frosting becomes too thick, add a tablespoon of heavy cream to thin it out.

Step 3: Add Vanilla and Adjust Consistency

Stir in the vanilla extract and a pinch of salt (if using). Continue beating until the frosting is light, fluffy, and spreadable. If necessary, add more cream, one tablespoon at a time, to reach your desired consistency.

Making Chocolate Ganache (Optional but Highly Recommended)

If you want to take this cake to the next level, you can make a simple chocolate ganache to drizzle over the top.

Step 1: Heat the Cream

In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer.

Step 2: Pour Over Chocolate

Place the chocolate chips in a heatproof bowl and pour the hot cream over them. Let it sit for 2–3 minutes to melt the chocolate.

Step 3: Stir Until Smooth

Whisk the chocolate and cream together until smooth and glossy. Allow it to cool slightly before using it to drizzle over the cake.

How to Assemble the Cake: A Step-by-Step Guide

Step 1: Level the Cake Layers

Once your cake layers are completely cool, use a serrated knife to level off the tops if they have domed during baking.

Step 2: Frost the First Layer

Place one cake layer on your serving platter. 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 first. Spread more peanut butter frosting over the top and around the sides of the cake.

Step 4: Drizzle with Chocolate Ganache

If using ganache, drizzle it over the top of the cake, allowing it to drip down the sides for an elegant finish.

Step 5: Decorate (Optional)

For added flair, you can decorate the top of the cake with chopped peanut butter cups, chocolate shavings, or peanuts.

Common Mistakes to Avoid

• Overmixing the Batter: Overmixing can lead to a dense cake. Mix until the ingredients are just combined.
• Not Letting the Cake Cool: Frosting a warm cake can cause the frosting to melt. Always let your cakes cool completely before frosting.
• Skipping the Boiling Water: Don’t skip the boiling water step! It’s crucial for achieving a moist texture.

Serving and Presentation Tips

When it comes to serving this cake, presentation is key. Here are a few tips to help you create a stunning dessert:

Presentation Ideas for Chocolate Peanut Butter Cake

• Add extra peanut butter cups on top for a fun and eye-catching garnish.

Chocolate Peanut Butter Cake Recipe Tips

• Make Ahead: You can bake the cake layers a day in advance and store them wrapped in plastic wrap at room temperature. Frost the cake on the day of serving.
• Storage: Leftover cake can be stored in an airtight container at room temperature for 2 days or in the fridge for up to 5 days.
• Freeze for Later: If you want to freeze the cake, wrap each layer separately in plastic wrap, then aluminum foil. Frost and assemble after thawing.

Frequently Asked Questions (FAQs)

Q: Can I use crunchy peanut butter instead of smooth?
A: While you can use crunchy peanut butter for a textured frosting, smooth peanut butter gives a more consistent, creamy finish.

Q: How long will this cake last?
A: Stored in an airtight container, this cake can last up to 5 days in the refrigerator.

Q: Can I make this cake without the chocolate ganache?
A: Absolutely! The cake is delicious on its own with just the peanut butter frosting.
