Ingredients for hershey dark chocolate cake
High-quality cocoa and chocolate bars make this cake irresistibly rich and fudgy.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 ½ cups | Cold, cubed for creaming |
| Granulated Sugar 🍚 | 2 ½ cups | White, fine grain preferred |
| Hershey's Special Dark Cocoa Powder 🍫 | ¾ cup | Not Dutch-processed for best flavor |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted, spooned lightly |
| Baking Powder 🍞 | 1 ½ tsp | Freshly opened |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Vanilla Extract 🌸 | 2 tsp | Pure, not imitation |
| Large Eggs 🥚 | 4 whole | Room temperature |
| Hershey's Special Dark Chocolate Bars 🍫 | 12 oz | 70% cocoa, chopped fine |
| Heavy Whipping Cream 🥛 | 1 cup | Full-fat for ganache |
| Powdered Sugar 🍚 | ¼ cup | For dusting optional |
| Milk 🥛 | ½ cup | Whole milk preferred |
The cocoa powder and chocolate bars are non-negotiable for that signature Hershey's depth. Hershey's Special Dark is the gold standard—it's what the brand uses in their own products. Walmart or Target usually carry it in the baking aisle, and it's worth the splurge. For the chocolate bars, grab the classic 70% cocoa ones (the ones with the orange wrapper). If you can't find them, Ghirardelli 70% or Lindt Excellence work too. The butter? Land O'Lakes or Plugrá unsalted—never salted. And don't even think about using margarine. The eggs should be room temperature—cold eggs make for dense cake.
No Hershey's cocoa? Dutch-processed cocoa plus 1 tbsp baking soda mimics it, but it won't be identical. Running short on chocolate bars? Substitute with 1 cup chopped walnuts or pecans for texture, though it'll lack chocolate flavor. The milk is just for adjusting consistency—water works in a pinch, but whole milk gives the best crumb. For the ganache, heavy cream must be full-fat—light cream makes it grainy. And if you're feeling fancy, add a splash of Kahlúa coffee liqueur to the ganache for extra depth.
This cake keeps beautifully—3 days at room temperature in a cake carrier, or 5 days refrigerated with a damp towel over it. The ganache hardens when chilled, so bring it to room temperature for 30 minutes before slicing. Leftovers reheat perfectly in 10-second bursts in the microwave. For parties, assemble the cake a day ahead—the flavors meld even better. And if you're making it for a crowd, double the recipe—it's worth it.

Step-by-step instructions for Hershey dark chocolate cake
Here's how to create a decadent chocolate cake with fudgy layers and a velvety ganache drizzle.
Cream Butter and Sugars for Maximum Fluffiness
In a stand mixer fitted with the paddle attachment, beat the 1.5 cups unsalted butter and 2.5 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. You'll notice the mixture nearly doubles in volume and becomes pale in color—this incorporates air for a tender crumb. Scrape down the sides of the bowl with a rubber spatula to ensure even mixing.
For best results, use cold butter that leaves a slight indentation when pressed. This ensures proper creaming without melting the fat too quickly. The texture should be smooth and ribbon-like when you lift the paddle—this is your signal that the butter and sugar are properly emulsified.
Incorporate Eggs and Dry Ingredients
Add the 4 whole large eggs, one at a time, mixing well after each addition until fully combined. Then stir in the 2 teaspoons vanilla extract. The mixture will appear slightly curdled, but don't worry—this will resolve when you add the dry ingredients. In a separate bowl, whisk together the 2.5 cups all-purpose flour, 0.75 cup Hershey's Special Dark Cocoa Powder, 1.5 teaspoons baking powder, and 0.5 teaspoon salt.
Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined. Avoid overmixing—you should still see small flour streaks. The batter will be thick and fudgy, which is exactly what we want for that rich, moist texture. For even distribution, use a spatula to gently fold in the batter from the bottom of the bowl.
Bake the Cake Layers
Preheat your oven to 350°F and grease two 8-inch round cake pans, then line the bottoms with parchment paper. Divide the batter evenly between the pans. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. The edges should be set, but the tops may still look slightly underdone—they'll firm up as they cool.
I like to rotate the pans halfway through baking for even heat distribution. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely. This gradual cooling prevents cracking and ensures clean layering later. The cakes should be moist but firm enough to handle when fully cooled.
Prepare the Chocolate Ganache
While the cakes cool, prepare the ganache by chopping the 12 ounces Hershey's Special Dark Chocolate Bars into small pieces and placing them in a heatproof bowl. In a small saucepan, heat the 1 cup heavy whipping cream and 0.5 cup milk over medium heat until it just begins to simmer. Pour the hot cream mixture over the chopped chocolate and let it sit for 5 minutes to soften.
Stir gently until the chocolate is completely melted and the mixture is smooth. The ganache should be glossy and thick enough to coat the back of a spoon. If it's too thick, warm it gently over low heat for 10-15 seconds to loosen. Let it cool slightly before using—it should be pourable but not runny.
Assemble and Drizzle
Once the cakes are completely cool, level the tops if needed. Place one cake layer on a serving plate and spread a thin layer of ganache over the top. Dust the layer with 0.25 cup powdered sugar for a decorative touch. Place the second cake layer on top and drizzle generously with the remaining ganache, allowing some to pool on the sides for that restaurant-quality finish.
For extra indulgence, repeat the ganache and powdered sugar layering once more. Serve immediately or refrigerate for 30 minutes before slicing—this helps the ganache set slightly for easier handling. Each slice should reveal a fudgy crumb with a glossy, rich chocolate ganache drizzle.
Pro Tips For Making Hershey Dark Chocolate Cake
- Melt Butter Slowly: Mix the melted butter and sugar until the sugar just dissolves—no need to overheat it. I learned this the hard way when my first batch tasted like caramelized sugar instead of chocolate. Let the butter come to room temp first, then melt it gently over low heat (or microwave in 20-second bursts) to avoid scorching.
- Sift the Cocoa Twice: Hershey’s Special Dark is dense—sift it before mixing with dry ingredients, then sift it again after combining with flour and baking powder. This prevents lumps that make your cake dense and grainy, no matter how much you stir. (Yes, it’s extra work, but the texture makes it worth it.)
- Don’t Overmix the Batter: Stop folding in the flour-cocoa mix the second it disappears—overmixing develops gluten and turns your cake into a dense brick. Use a spatula to gently cut through the batter until just combined. I used to think more mixing = better texture, but this is where the cake’s lightness lives or dies.
- Use a Toothpick Test: Check doneness at 25–30 minutes, not the full 35–40 minutes the recipe says. Insert a toothpick into the center—if it comes out with moist crumbs (not wet batter), pull it out. Oven temps vary, and Hershey’s dark cocoa can make cakes set faster than you’d expect. (Your future self will thank you for not drying out the cake.)
Perfect pairings for this hershey dark chocolate cake
Coffee Pairings
This rich chocolate cake pairs beautifully with a medium-roast coffee like Starbucks Sumatra or Peet's Major Dickason's Blend. The deep, earthy notes of Sumatra complement the dark cocoa without overpowering it.
For an espresso martini vibe, try a double shot of cold brew with a splash of Kahlúa—the coffee's bitterness cuts through the sweetness while enhancing the chocolate's depth. 💛
Wine Pairings
A Cabernet Sauvignon with 12-14% ABV is my go-to—look for Louis M. Martini Cabernet or Apothic Red Blend. The wine's dark fruit flavors and tannins mirror the chocolate's richness, while its acidity balances the cake's sweetness.
For a lighter option, a Pinot Noir like La Crema Sonoma Coast offers a silky texture that won't compete with the ganache's intensity.
Creamy Dessert Wines
Skip the reds and go for Banyuls, a fortified French wine with 15% ABV and flavors of chocolate and berries. Château Tour des Gendres is a classic choice that enhances the cake's fudgy layers.
Alternatively, a Port wine like Graham's 10-Year-Old Tawny adds a caramelized sweetness that pairs like a dream with the ganache's glossy finish.
Non-Alcoholic Options
For a refreshing contrast, serve with chilled chai tea—I love Tazo Passion Chai with a splash of vanilla almond milk. The spiced notes elevate the chocolate's depth without adding alcohol.
For a kid-friendly option, hot chocolate made with Ghirardelli squares and half-and-half turns the cake into a decadent dessert duo. 🌟
Fruit Complements
Add a raspberry coulis or blackberry compote to cut through the richness. Simmer 1 cup fresh berries with 2 tbsp sugar and 1 tsp lemon juice until reduced to a thick sauce.
The tartness brightens each bite, making the chocolate taste even more luxurious. For a tropical twist, serve with mango slices—their sweetness harmonizes with the ganache's richness.
Spiced Accents
Garnish with a sprinkle of orange zest or a pinch of cinnamon to add warmth. The citrus notes enhance the chocolate's complexity, while cinnamon deepens the cake's spiced undertones.
For a bold touch, add a dash of cayenne pepper—it sounds crazy, but the heat makes the chocolate taste even more intense. Trust me, it works! ⚡

Frequently asked questions
Why does this cake use both cocoa powder AND chocolate bars?
The combination creates that signature Hershey's depth. The cocoa powder develops the cake's structure and rich chocolate flavor, while the chopped chocolate bars add fudgy pockets throughout each layer. Without both, you'd either get a denser cake or one that lacks that signature melt-in-your-mouth texture.
Can I make this cake in a 9-inch pan instead of 8-inch?
Yes, but you'll need to adjust the baking time. For a 9-inch pan, bake for 20-25 minutes instead of 25-30. The cake will be thinner, so reduce the ganache by about 25% to avoid overwhelming the layers. The texture will still be fudgy, but the overall structure will be slightly lighter.
What's the best way to store leftovers?
Keep the cake in an airtight container at room temperature for up to 3 days, or refrigerate for 5 days with a damp towel over it to prevent drying. For longer storage, freeze individual slices wrapped in plastic for up to 1 month. Thaw at room temperature for 1 hour before serving.
My cake turned out dry—what went wrong?
Overbaking or using old ingredients are the most common culprits. Always check for doneness with a toothpick at 25 minutes—the cake should be set but still slightly springy. Also ensure your cocoa powder and chocolate bars are fresh (check expiration dates!). For extra moisture, brush the cooled layers with a simple syrup made from equal parts water and sugar.
Can I make this cake gluten-free?
Yes, but you'll need to substitute the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill) plus 1 teaspoon xanthan gum. Add 2 tablespoons extra milk to compensate for the blend's dryness. The texture will be slightly denser, but still delicious. For best results, use a gluten-free cocoa powder as well.
