Ingredients for hershey dark chocolate cake
Five essential ingredients plus chocolate magic for a velvety cake with crackly top and fudgy layers.
| Ingredient | Amount | Notes |
|---|---|---|
| Hershey's Special Dark Cocoa Powder 🍫 | ¾ cup | Unsweetened, for deep chocolate flavor |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted, for light texture |
| Granulated White Sugar 🍚 | 1 ½ cups | Standard grocery store variety |
| Buttermilk 🥛 | 1 cup | Full-fat for richness |
| Unsalted Butter 🧈 | ¾ cup | Room temperature, salted substituted |
| Large Eggs 🥚 | 2 whole | Room temperature, separated |
| Baking Soda 🧂 | ½ tsp | Pure, for lift |
| Vanilla Extract 🌿 | 1 tbsp | Pure, high-quality |
| Fine Sea Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Hershey's Semi-Sweet Chocolate Bars 🍫 | 6 oz | Chopped, for fudgy texture |
| Powdered Sugar 🍚 | ¼ cup | For glaze, sifted |
| Heavy Cream 🥛 | ¼ cup | Cold, for glaze |
The Hershey's Special Dark Cocoa Powder is non-negotiable for that signature deep, slightly bitter chocolate flavor. Grab the 16-ounce canister from any major grocery store—it's the same powder used in classic Hershey's recipes. For the butter, Land O'Lakes unsalted sticks work perfectly, but if you only have salted, reduce the added salt by half. The buttermilk should be thick and tangy—if yours is thin, add 1 teaspoon of lemon juice. For the chocolate bars, use the classic milk chocolate variety (not dark)—the sweetness balances the cocoa powder beautifully. Pre-sift your dry ingredients to avoid lumps in the batter, which is especially critical for the cocoa powder's fine texture.
No buttermilk? Substitute 1 cup of milk with 1 tablespoon of vinegar or lemon juice, let it sit for 5 minutes. Short on Hershey's bars? Use 6 ounces of semi-sweet chocolate chips, but chop them finely for even distribution. The vanilla extract should be pure, not imitation—McCormick or Nielsen-Massey are reliable brands. For the glaze, if you prefer a glossier finish, add 1 teaspoon of corn syrup to the powdered sugar mixture. The eggs must be room temperature—cold eggs create air pockets in the batter, leading to a dense cake. If you're baking at high altitude, reduce the baking soda by 0.25 teaspoons and add 1 tablespoon of water to the batter.
This cake stays moist for 4-5 days when stored properly: wrap tightly in plastic wrap, then place in an airtight container. For longer storage, freeze the whole cake (unfrosted) for up to 3 months—thaw at room temperature before serving. The glaze sets quickly, so assemble the cake as soon as it comes out of the oven. If you have leftovers, reheat slices for 10-15 seconds in the microwave to restore the crackly top. The aroma alone will fill your kitchen—bake it when you want to make your home smell like a bakery.
Why You'll Love This Recipe
- Let’s be real: most cakes dry out or get sad after a day. Not this one. The buttermilk keeps it moist for days, and I’ve had slices that were even better the next morning—warm, with a sprinkle of powdered sugar. Plus, it’s budget-friendly enough that I don’t feel guilty making a whole batch just for myself.
- Pantry Stash Magic: I swear by this recipe because it uses ingredients I already have. No special shopping trips—just that rich Hershey’s cocoa, a stick of butter, and a splash of buttermilk. Honestly, it’s the kind of cake that makes me feel like I’ve done something impressive without actually breaking a sweat.
- Rich Without Bitterness: The Hershey’s Special Dark cocoa delivers that deep, velvety chocolate flavor without tasting like a science experiment. That buttermilk tenderizes the crumb while keeping it moist, and the sugar caramelizes just enough to give it a subtle crunch. Between us, it’s the kind of cake that makes me forget about "healthy" for a second.
- Date Night or Dessert Emergency: This cake is my go-to for last-minute gatherings—whether it’s a quick dinner with friends or a solo midnight snack. I’ve frosted it with whipped cream, served it warm with ice cream, or even cut it into squares for a fancy charcuterie board. (Yes, even on a Tuesday night.)
Step-by-step instructions for Hershey dark chocolate cake recipe
This one-bowl method delivers layers of fudgy richness and moist texture without overmixing or complex techniques.
Prepare the Chocolate Base
In a large mixing bowl, combine the 0.75 cup Hershey's Special Dark Cocoa Powder, 1.5 cups Granulated White Sugar, 0.5 tsp Fine Sea Salt, and 1 tbsp Vanilla Extract. Whisk vigorously for 2 minutes until the mixture is completely smooth and homogeneous. This ensures even distribution of the cocoa's deep flavor throughout the batter.
Next, add the 2 whole Large Eggs and mix again for 1 minute until fully incorporated. The eggs will begin to emulsify with the dry ingredients, creating a slightly thickened paste. This step is critical for developing the cake's structure while maintaining moisture—don't skip it.
Incorporate Wet Ingredients
In a separate bowl, melt the 0.75 cup Unsalted Butter in the microwave in 20-second intervals, stirring between each interval, until completely liquid. Let it cool slightly for 1 minute—it should be warm to the touch but not hot.
Gradually pour the melted butter into the chocolate mixture while mixing on low speed with an electric mixer. Add the 1 cup Buttermilk in a slow, steady stream, mixing continuously for 3 minutes until the batter is smooth and well combined. The buttermilk adds richness and tenderness, while the butter creates a velvety texture. If the batter appears too thick, add 1 tablespoon of water to achieve a pudding-like consistency.
Fold in Chocolate and Leavening
Chop the 6 oz Hershey's Semi-Sweet Chocolate Bars into small, even pieces—about ½-inch cubes. Gently fold half of the chopped chocolate into the batter by hand using a spatula, ensuring even distribution without overmixing. Then, sprinkle the 0.5 tsp Baking Soda over the batter and fold it in completely.
Add the remaining chopped chocolate and mix just until combined. The baking soda will react with the buttermilk and eggs to create lift, while the chocolate ensures a fudgy depth in every bite. Avoid overmixing at this stage—lumps are fine, as they'll melt into the cake during baking.
Bake for Moist, Fudgy Perfection
Preheat your oven to 350°F and grease a 9-inch round cake pan with butter or nonstick spray. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 30-35 minutes, or until a toothpick inserted into the center emerges with a few moist crumbs but no wet batter. Overbaking will dry out the cake, so watch closely during the last 5 minutes of baking.
Once baked, remove the cake from the oven and let it cool in the pan for 10 minutes. Then, transfer it to a wire rack to cool completely. The internal temperature should drop to 100°F before frosting to prevent melting.
Prepare the Chocolate Glaze
In a small saucepan, combine the 0.25 cup Powdered Sugar, 0.25 cup Heavy Cream, and 2 oz of the chopped Hershey's Semi-Sweet Chocolate Bars. Place the saucepan over low heat and stir gently until the mixture reaches 110°F and the chocolate melts completely, forming a smooth, glossy glaze. Remove from heat and let it cool for 2 minutes—it should thicken slightly but remain pourable.
Drizzle the glaze evenly over the cooled cake, allowing any excess to drip down the sides for a professional finish. The glaze should set within 15 minutes, creating a mirror-like sheen that enhances the cake's fudgy richness. Serve immediately or refrigerate for up to 2 hours before slicing—this ensures clean cuts and maximum moisture in every bite.
Pro Tips For Making Hershey Dark Chocolate Cake
- Sift the Cocoa: I learned this the hard way—clumping cocoa powder ruins the texture. Use a fine-mesh sieve to sift the Hershey’s Special Dark directly into your dry ingredients. This keeps the flour light and prevents those dreaded dense pockets in the middle.
- Melt Butter Slowly: Don’t nuke that butter—melt it gently over a double boiler or in the microwave in 20-second bursts, stirring between each. Cold butter in the batter can cause lumps, and Hershey’s dark cocoa already makes this cake rich enough without fighting for even mixing.
- Don’t Overmix Wet Ingredients: Once you add the buttermilk to the butter-sugar mix, stir just until combined—maybe 10-12 strokes max. Overmixing introduces air that collapses during baking, leaving you with a cake that’s dense instead of light and fudgy. Trust the process.
- Test with a Toothpick: Skip the "press the center" trick—it’s misleading. Insert a toothpick into the cake’s thickest part; if it comes out with a few moist crumbs but no wet batter, it’s done. Hershey’s dark cocoa can make the edges look set while the middle’s still undercooked.

In the South, this cake gets a cozy twist by adding ½ cup of brewed coffee to the batter, replacing half the buttermilk. The coffee enhances the chocolate flavor while keeping the texture moist—just like a classic Southern chocolate cake.
I like to top it with a whipped cream frosting> mixed with 1 tablespoon of instant espresso powder for extra depth. Serve warm with a scoop of vanilla ice cream for that true Southern dessert experience. 🌶️
Midwest Fudge Swirl
The Midwest takes this cake to another level by incorporating a fudge swirl> into the batter. After folding in the baking soda, drop spoonfuls of Hershey's fudge sauce> (warmed slightly) into the batter, then gently swirl with a knife.

Pair it with a sprinkle of toasted pecans> for crunch. This version feels like a hug on a chilly autumn day—perfect for Thanksgiving or holiday baking. 🍂
West Coast Decadent Twist
Out West, they love their chocolate with a fruity kick. After baking, I drizzle the cake with a raspberry coulis> (simmer 1 cup raspberries> with 2 tablespoons sugar> until thickened) before adding the chocolate glaze.
The tartness cuts through the richness beautifully. For extra flair, add chopped candied orange peel> to the batter—it’s a signature touch in California bakeries. 🍓
Canadian Maple Infusion
Our neighbors to the north take this cake and make it their own by adding 2 tablespoons of pure maple syrup> to the batter. The syrup replaces some of the sugar and adds a subtle caramel note that pairs perfectly with the chocolate.

Frequently asked questions
Can I use regular cocoa powder instead of Hershey's Special Dark?
While you can substitute, Hershey's Special Dark provides that signature deep, slightly bitter chocolate flavor that regular cocoa powder lacks. For the closest result, use 1 cup of Dutch-process cocoa powder (like Ghirardelli) and reduce the sugar slightly to 1.25 cups to balance the sweetness. The texture will be similar, but the flavor profile won't be identical.
Why did my cake turn out dense instead of moist?
Overmixing the batter is the most common cause—whisk the dry ingredients for only 2 minutes and mix wet ingredients gently for 3 minutes. Another issue could be underbaking: check at 30 minutes with a toothpick. If it comes out clean, the cake needs more time. Also ensure your butter is room temperature and eggs are separated properly.
How do I make this cake gluten-free?
Replace the 1.5 cups all-purpose flour with 1.25 cups gluten-free 1:1 baking flour (like Bob's Red Mill) plus 0.25 cup cornstarch. Add 0.5 teaspoon xanthan gum if your blend doesn't contain it. Sift all dry ingredients together thoroughly to prevent lumps. The texture will be slightly denser but still delicious.
Can I bake this cake in a different pan size?
Yes, but adjust the baking time. For a 8-inch pan, bake 25-30 minutes and for a 10-inch pan, bake 35-40 minutes. Always check with a toothpick at the lower end of the range. The cake should spring back slightly when touched. A 9-inch pan gives the best texture for this recipe.
What's the best way to store leftovers?
Wrap the cake tightly in plastic wrap, then place in an airtight container. It stays fresh for 4-5 days at room temperature or up to 3 months frozen. For frozen cake, thaw overnight in the refrigerator. To revive the texture, warm slices for 10-15 seconds in the microwave before serving.
