Ingredients You’ll Need

Creating this Chocolate Peanut Butter Fudge Cake only requires baking staples and a few simple upgrades. Each ingredient plays a starring role, from the cocoa for a deep chocolate taste to the buttermilk for delicately moist layers. Here’s how every element contributes to the cake’s irresistible flavor and texture:

• All-purpose flour: Provides the perfect foundation for a tender yet sturdy crumb in your cake layers.
• Granulated sugar: Adds sweetness and helps keep the cake moist.
• Unsweetened cocoa powder: Gives a deep, intense chocolate flavor essential to the cake’s character.
• Baking soda: Acts as a leavening agent, helping the cake rise wonderfully.
• Baking powder: Another leavening hero, ensuring maximum lift and fluffiness.
• Salt: Balances sweetness and heightens the chocolate and peanut butter flavors.
• Buttermilk: Brings rich flavor and an ultra-tender crumb to the cake.
• Vegetable oil: Keeps the cake moist for days and gives it a luscious mouthfeel.
• Large eggs: Offer structure and richness to the batter.
• Vanilla extract: Adds depth and rounds out both chocolate and peanut flavors.
• Hot coffee: Intensifies the chocolatey notes and adds moistness.
• Unsalted butter (for frosting): The creamy, rich base for a decadent frosting.
• Creamy peanut butter (for frosting): Creates that signature fudge-like texture and flavor.
• Powdered sugar (for frosting): Whips up a perfectly smooth, sweet frosting.
• Milk or heavy cream (for frosting): Controls consistency, making the frosting spreadable and fluffy.
• More unsweetened cocoa powder (for frosting): Ensures the sweet, fudgy balance in every bite.
• Vanilla extract (for frosting): Elevates the flavors to their absolute best.
• Pinch of salt (for frosting): A little bit ties the flavors beautifully together.
• Semi-sweet chocolate chips (for ganache): Melt into a velvety ganache that’s perfect for dripping.

• Mini chocolate chips (for garnish): Add crave-worthy crunch and visual appeal as the finishing touch.

How to Make Chocolate Peanut Butter Fudge Cake**

Step 1: Prepare the Cake Pans and Oven

Start by preheating your oven to 350°F (175°C) and take a few moments to grease and flour two 8-inch round pans. Don’t skip this step—there’s nothing more satisfying than seeing your cake layers release from the pans without a hint of sticking. This bit of prep ensures your Chocolate Peanut Butter Fudge Cake** looks as perfect as it tastes.

Step 2: Mix the Dry Ingredients

In a large bowl, whisk together the flour, sugar, unsweetened cocoa powder, baking soda, baking powder, and salt. Mixing these ingredients well guarantees an even texture, so every forkful of your cake is perfectly balanced and smooth.

Step 3: Blend in the Wet Ingredients

Add the buttermilk, vegetable oil, eggs, and vanilla extract to your dry mix. Use a mixer on medium speed and blend for about 2 minutes. This step makes the batter silky, bringing together all the classic flavors that make Chocolate Peanut Butter Fudge Cake** so irresistible.

Step 4: Add Hot Coffee

Carefully stir in the hot coffee until the mixture looks smooth and ultra-thin. Don’t worry about the runny batter—it’s the secret to those extra-moist, melt-in-your-mouth layers of cake. Plus, the coffee highlights the richness of the chocolate without making the cake taste like your morning brew.

Step 5: Bake the Cake Layers

Evenly divide the batter between your prepared pans, then slide them into the oven. Bake for 30-35 minutes, until a toothpick comes out clean from the center. Allow the cakes to cool in the pans for 10 minutes, then transfer to a wire rack. Letting them cool fully avoids melting the frosting later—a small step with big results!

Step 6: Make the Peanut Butter Fudge Frosting

With a stand mixer, beat together softened butter and creamy peanut butter until airy and smooth. Add in the cocoa powder and gradually alternate the powdered sugar with milk or heavy cream. Finish by beating in vanilla extract and a pinch of salt for that fudge frosting you’ll want to eat by the spoonful!

Step 7: Prepare the Ganache Drip

In a small saucepan, heat the heavy whipping cream just until it begins to simmer, then pour it directly over semi-sweet chocolate chips in a heatproof bowl. Let the mixture sit for five minutes—no stirring yet! Then whisk until glossy and pourable. This is what gives your Chocolate Peanut Butter Fudge Cake** its show-stopping look.

Step 8: Assemble and Decorate

Place one cooled cake layer on a serving plate. Smother the top with a generous layer of peanut butter fudge frosting. Add the next layer, then cover the cake completely with more frosting. Use a piping bag to add pretty swirls around the border. Slowly drizzle the chocolate ganache over the top, letting it drip down the sides in dramatic, delicious fashion. Finish by sprinkling mini chocolate chips all over for crunchy, chocolatey bursts in every bite.

How to Serve Chocolate Peanut Butter Fudge Cake**

Garnishes

The final flourish truly matters! Aside from mini chocolate chips, try crumbled peanut butter cups, a pinch of flaky sea salt, or a handful of roasted peanuts for extra texture and visual drama. Each garnish boosts the cake’s already luxurious vibe and gives you a chance to make it your own.

Side Dishes

This chocolatey masterpiece loves company. Serve slices alongside scoops of vanilla ice cream or raspberry sorbet for a chilly contrast. A fresh fruit salad with juicy berries can cut through the richness, or set out a platter of salty pretzels to play off the sweet-salty notes in the Chocolate Peanut Butter Fudge Cake**.

Creative Ways to Present

Want to turn dessert into an event? Mini layer cakes or cupcakes using this recipe are ideal for parties. Try stacking two thin layers in a glass jar for an easy, portable treat. If you’re feeling fancy, use gold sprinkles, edible glitter, or dot ganache hearts on each slice for extra flair.

Make Ahead and Storage

Storing Leftovers

Leftover slices keep beautifully when wrapped tightly in plastic wrap and stored in an airtight container at room temperature for up to two days or in the fridge for four to five days. The cake actually gets moister as it sits, so you might find it tastes even better the second day!

Freezing

If you want to save your Chocolate Peanut Butter Fudge Cake** for a later celebration, freezing is simple. Wrap individual slices or the whole (completely cooled and unfrosted) cake tightly in two layers of plastic wrap, then in foil. It’ll stay fresh for up to three months. When ready to enjoy, thaw in the fridge overnight and bring to room temperature before frosting and serving.

Reheating

While this cake is fantastic served at room temperature, if you want to bring back a fresh-from-the-oven softness, microwave a slice for 10-15 seconds. This warms the frosting just enough to make it gooey and decadent again, especially if pairing with ice cream.

FAQs

Can I use natural peanut butter for the frosting?

You can, but be aware that natural peanut butter tends to separate and can make the frosting less stable and oily. For the smoothest, fluffiest peanut butter fudge frosting, stick with creamy, no-stir varieties like Jif or Skippy.

What if I don’t have buttermilk?

No worries! Just add one tablespoon of white vinegar or lemon juice to a measuring cup, then fill to the one-cup mark with whole milk. Let it sit for a few minutes—it’ll turn into a great buttermilk substitute for your Chocolate Peanut Butter Fudge Cake**.

Can I make this recipe as cupcakes?

Absolutely! This recipe translates beautifully into cupcakes. Fill liners two-thirds full and bake at 350°F (175°C) for 18-22 minutes, checking with a toothpick for doneness.

How do I get clean, professional-looking cake slices?

For those photo-worthy slices, dip your knife in hot water and wipe it dry between cuts. This simple trick helps you slice right through thick frosting and ganache, keeping every layer neat and distinct.

Can I prepare the cake layers ahead of time?

Yes! Bake and cool the cake layers up to two days in advance. Wrap them tightly and refrigerate, then frost and assemble your Chocolate Peanut Butter Fudge Cake** when you’re ready. This actually makes assembly easier and minimizes crumbs.

Final Thoughts

If you’re ready to wow friends, family, or just treat yourself, don’t wait another day to make this Chocolate Peanut Butter Fudge Cake**. It’s sheer delight in edible form, delivering fudgy, chocolate-peanut butter bliss with every bite. You’re going to love serving it just as much as you love eating it!
