Unlock the ultimate Hershey's chocolate chocolate cake recipe—where rich, fudgy layers and a hidden twist turn simple cake into pure indulgence. The magic lies in blending melted Hershey's chocolate bars directly into the batter, ensuring every bite carries that signature Hershey's flavor—rich, velvety, and irresistibly sweet.
After years of testing, I've perfected a method that guarantees moist layers without drying out, even when baked to golden perfection.
The recipe relies on three key elements: Hershey's chocolate bars for unmatched flavor, buttermilk for tenderness, and a precise baking technique that prevents cracking. Unlike traditional chocolate cakes, this version uses Hershey's syrup in the frosting, creating a glossy, ultra-chocolatey finish that ties the entire dessert together.
The cake's texture is what sets it apart—fudgy yet tender, with a crumb that practically melts in your mouth.
What makes this recipe truly special is how it balances simplicity with professional results. With just 10 ingredients and 60 minutes of active time (plus cooling), you'll end up with a showstopping dessert that tastes like it came from a bakery.
The Hershey's chocolate isn't just an ingredient—it's the star, infusing every layer with that nostalgic, childhood-flavor nostalgia that makes this cake impossible to resist.
Perfect for birthdays, holidays, or whenever you crave a decadent treat, this cake pairs beautifully with vanilla ice cream or whipped cream. The frosting is thick enough to hold its shape but spreadable enough to create clean, elegant swirls. Let’s get baking—your taste buds will thank you.
Ingredients for hershey's chocolate chocolate cake
Twelve ingredients transform into decadent layers of Hershey's chocolate perfection—rich, fudgy, and nostalgically sweet.
| Ingredient | Amount | Notes |
|---|---|---|
| Hershey's Milk Chocolate Bars 🍫 | 12 oz | High-quality, chopped finely |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Granulated Sugar 🍚 | 2 ¼ cups | White, fine grain preferred |
| Unsalted Butter 🧈 | 1 ¼ cups | Cold, cubed for creaming |
| Large Eggs 🥚 | 3 whole | Room temperature for blending |
| Buttermilk 🥛 | 1 ¼ cups | Fresh, full-fat preferred |
| Baking Soda 🧂 | 1 ½ tsp | Pure, unadulterated |
| Vanilla Extract 🍯 | 1 tbsp | Pure, high-quality |
| Hershey's Chocolate Syrup 🍯 | 1 cup | For frosting, not substitute |
| Powdered Sugar 🍚 | 3 cups | Fine, sifted for frosting |
| Cocoa Powder 🍫 | ½ cup | Dutch-processed for smoothness |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
The Hershey's chocolate bars are non-negotiable for that signature flavor. Buy the full-size bars—miniatures lack the intensity. Chop them finely for even distribution in the batter. Costco or grocery store bakery sections often carry them in bulk. For the cocoa powder, Dutch-processed ensures a smoother texture without bitterness. The buttermilk should be fresh—if it's curdled, strain it through a fine mesh. Butter matters too: unsalted, cold, and cubed creates the perfect creamed texture. Pre-sifted flour saves time, but sifting at home eliminates lumps for a lighter crumb.
No Hershey's syrup for frosting? Melted chocolate bars mixed with powdered sugar works in a pinch, though it lacks the glossy finish. Substitute buttermilk with 1 cup milk + 1 tbsp vinegar, but let it sit 5 minutes to curdle properly. For a lighter cake, replace 0.5 cup flour with cornstarch. The vanilla extract should be pure—imitation extracts often contain alcohol that can dry out the cake. If you're gluten-free, swap the flour for a 1:1 baking blend, but expect slightly denser layers. The cocoa powder is crucial: natural cocoa will make the cake darker but more acidic-tasting compared to Dutch-processed.
Store the cake layers wrapped in plastic at room temperature for 3 days or in the fridge for 1 week. The frosting keeps 5 days refrigerated or 3 months frozen. For make-ahead baking, assemble the cake unfrosted, wrap tightly, and freeze. Thaw overnight before frosting. The chocolate bars can be chopped ahead and stored in an airtight container for 2 weeks. Powdered sugar absorbs moisture—keep it sealed in a cool, dry place. The frosting thickens when chilled, so bring it to room temperature before spreading for perfect swirls.

Step-by-step instructions for Hershey's chocolate chocolate cake
This method delivers a decadent, fudgy cake with double chocolate intensity and a rich Hershey's chocolate syrup frosting.
Prepare the Chocolate Cake Batter
Preheat your oven to 350°F and grease two 9-inch round cake pans with butter, then line the bottoms with parchment paper. In a microwave-safe bowl, melt the 12 oz Hershey's Milk Chocolate Bars in 30-second intervals, stirring between each, until completely smooth. Let it cool slightly to 110°F—it should be warm but not hot to the touch.
In a separate large mixing bowl, combine the 2.5 cups All-Purpose Flour, 0.5 cup Cocoa Powder, 1.5 tsp Baking Soda, and 0.5 tsp Salt. Whisk together until no lumps remain. In another bowl, beat the 1.25 cups Unsalted Butter and 2.25 cups Granulated Sugar on medium speed until light and fluffy, about 3-4 minutes. Add the 3 whole Large Eggs, one at a time, mixing well after each addition. Stir in the 1 tbsp Vanilla Extract and the cooled melted chocolate.
Alternate adding the dry ingredients and 1.25 cups Buttermilk to the wet mixture, beginning and ending with the dry ingredients. Mix on low speed just until combined—overmixing develops gluten, which can make the cake dense. Pour the batter evenly between the prepared cake pans and smooth the tops with a spatula.
Bake the Cake Layers
Bake the cakes for 30-35 minutes, or until a toothpick inserted into the center comes out clean with just a few moist crumbs clinging to it. The edges should be set, but the tops may still look slightly soft. Rotate the pans halfway through baking for even browning. Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely before frosting.
Here's the thing—don't rush this cooling step. Warm cakes absorb moisture from the frosting, making it runny and ruining the texture. If you're impatient, tent the cakes loosely with foil while they cool to speed up the process slightly, but don't skip this entirely.
Prepare the Hershey's Chocolate Syrup Frosting
In a medium bowl, beat the 1.25 cups Unsalted Butter (softened but not melted) until smooth. Gradually add the 3 cups Powdered Sugar, mixing on low speed until fully incorporated. Add the 1 cup Hershey's Chocolate Syrup and the 1 tbsp Vanilla Extract, then beat on medium speed until the frosting is light, fluffy, and fully combined. Taste and adjust sweetness if needed—you can add a splash of milk or more powdered sugar to reach your preferred consistency.
The frosting should be thick enough to hold its shape when spread but still pipeable. If it's too stiff, soften it slightly with 1 teaspoon of milk at a time. This frosting is the star of the cake, so take your time to get it just right—it should be glossy, smooth, and rich with Hershey's chocolate flavor.
Assemble and Frost the Cake
Place one cake layer on a cake stand or plate. Spread a thin layer of frosting over the top to create a "crumb coat." This step prevents crumbs from getting into the final frosting layer. Chill the cake in the refrigerator for 15 minutes to set the crumb coat. Repeat with the second layer, then frost the entire cake with the remaining frosting.
Use a long spatula or bench scraper to create smooth sides. For extra decadence, pipe rosettes or swirls around the edges with a piping bag fitted with a star tip. Dust the top with a light layer of cocoa powder using a fine-mesh sieve for a professional touch. Serve immediately or refrigerate for up to 3 days—though it won't last that long in your kitchen.
Pro Tips For Making Hershey'S Chocolate Chocolate Cake
- MELT CHOCOLATE SLOWLY: I learned this the hard way—dumping chopped Hershey’s bars straight into hot butter makes a greasy mess. Instead, chop the chocolate into small, even pieces and melt them with the butter over low heat, stirring constantly. If it starts seizing up, take the pan off the heat for 10 seconds and let it relax. You want smooth, glossy chocolate, not scrambled bits.
- SIFT THE FLOUR: Skipping this step means dense, uneven cake. After mixing the dry ingredients, give the flour a quick sift into the bowl—especially if it’s lumpy or old. A fine, airy flour blend incorporates better and prevents a heavy texture. (Yes, even if you’re impatient like me.)
- DON’T OVERMIX THE BATTER: I used to beat this batter until it looked like glue. Wrong move. Mix the wet and dry ingredients just until combined—lumps are fine—then stop. Overmixing develops gluten, which turns your rich chocolate cake into a tough, dry brick. Fold in the melted chocolate last, and only until it’s barely streaked.
- CHILL THE BATTER 10 MINUTES: This isn’t the prettiest method, but it’s the tastiest. After mixing, let the batter sit for 10 minutes before baking. The flour absorbs extra liquid, and the chocolate settles, preventing cracks and a domed top. (Your future self will thank you—trust me.)
Wine and beer pairings for this hershey's chocolate chocolate cake
Sweet Red Wine
For this rich, chocolatey cake, a Cabernet Sauvignon or Merlot from Napa Valley is my go-to choice. The bold, fruity notes of these wines—think blackberry, plum, and a touch of vanilla—complement the Hershey's chocolate without overpowering it.
I recommend a 2018 Robert Mondavi Reserve Cabernet for its smooth tannins and chocolate undertones that mirror the cake's depth. 🍷
Port Wine
If you want something truly decadent, serve this cake with a Ruby Port like Graham's 10-Year-Old. The caramel and dried fruit flavors in the port enhance the cake's chocolate richness, creating a harmonious pairing that feels like a dessert in itself.
Port also works beautifully as an ice cream substitute—drizzle it over a slice for an elegant touch.
Creamy Beer Pairings
A stout beer like Guinness or Samuel Adams Black Lager cuts through the sweetness of the cake with its roasted malt flavors. The slight bitterness balances the chocolate's intensity, making each bite more complex.
For a lighter option, try a Belgian-style Dubbel like Westmalle Trappist—its caramel and spice notes create a beautiful contrast with the Hershey's frosting.
Coffee Liqueur
If you're serving this cake after dinner, a small glass of Kahlúa or Tia Maria alongside a cup of espresso elevates the experience. The coffee's bitterness and chocolate notes create a perfect synergy with the cake's Hershey's flavor.
I like to serve this pairing with a slice of cake and a dollop of whipped cream for a restaurant-quality dessert experience. ☕
Champagne or Sparkling Wine
For a celebratory occasion, pair this cake with a demi-sec Champagne like Moët & Chandon or a Prosecco. The bubbles and slight sweetness cleanse your palate between bites, making the cake's richness even more enjoyable.
This pairing works especially well for birthdays or anniversaries when you want to impress your guests. 🥂

Frequently asked questions
Can I substitute Hershey's chocolate bars with chocolate chips?
Yes, but the texture and flavor will differ slightly. Use 2 cups of chocolate chips instead of 12 oz of bars, but melt them first to ensure even distribution. Chocolate chips often contain additives that can make the cake slightly denser. For the best Hershey's flavor, stick to the bars—it's what makes this cake truly special!
Why does my cake turn out dry or crumbly?
Overbaking or overmixing are the most common culprits. Bake until a toothpick comes out with moist crumbs, not clean. Also, don't overmix the batter—just combine until smooth. For extra moisture, add 1 tablespoon of coffee to the batter or brush layers with simple syrup before frosting. The buttermilk is key for tenderness!
How do I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend like Bob's Red Mill. You'll likely need to add 1 teaspoon of xanthan gum to mimic gluten's structure. The texture will be slightly denser, but still delicious! For the best results, use a blend designed for cakes rather than all-purpose GF flour.
Can I bake this cake in a single 9x13-inch pan?
Yes, but expect a thicker, denser texture. Reduce baking time to 25-30 minutes at 350°F and check for doneness early. For a more traditional cake experience, stick to two 9-inch pans. If you do use a single pan, consider adding 1 extra egg white to help with rise and moisture.
What's the secret to perfectly smooth frosting?
Beat the butter until completely smooth before adding powdered sugar, and let the frosting rest for 10 minutes before using. If it's too thick, add milk 1 teaspoon at a time. For extra gloss, brush the finished cake with a tiny bit of Hershey's chocolate syrup mixed with 1 teaspoon of water. Chill the cake for 30 minutes before serving to set the frosting perfectly.
