Ingredients for hershey's especially dark chocolate cake
Eight essential ingredients transform into a velvety, fudgy masterpiece using baking soda’s magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Hershey's Especially Dark Chocolate Bars 🍫 | 8 oz | High-quality, semi-sweet chocolate |
| All-Purpose Flour 🌾 | 2 cups | Sifted for even texture |
| Granulated White Sugar 🍚 | 1 ½ cups | Standard grocery store brand |
| Baking Soda 🧪 | 1 tbsp | Pure, fine-grained |
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat |
| Buttermilk 🥛 | 1 cup | Fresh, not powdered |
| Vanilla Extract 🌸 | 1 tbsp | Pure, alcohol-based |
| Salt 🧂 | ½ tsp | Diamond Crystal kosher |
| Vegetable Oil 🫒 | ¼ cup | Light, neutral flavor |
The chocolate is non-negotiable—Hershey's Especially Dark delivers that signature depth. Ghirardelli or Guittard bars work as premium alternatives, but Hershey’s strikes the perfect balance of richness and accessibility. For the butter, Land O’Lakes or Plugrá brands ensure consistent performance, while the baking soda must be fresh (Arm & Hammer is a reliable choice). The buttermilk’s tanginess is critical; Great Value or Homeland brands from grocery stores suffice, but if you’re feeling fancy, Cultivate brand offers a richer profile. Sift the flour thoroughly to prevent dense layers, and measure the sugar precisely—Domino or C&H brands work well.
No buttermilk? Substitute with 1 cup milk plus 1 tbsp vinegar, let sit for 5 minutes. Short on chocolate? Add 1 oz extra butter to compensate for texture. The vanilla extract can be swapped for 1 tsp vanilla bean paste if you prefer intensity. For a lighter crumb, replace 0.25 cup of the flour with cornstarch. The baking soda’s chemical reaction with buttermilk creates the signature moisture—never substitute with baking powder. If you’re baking at high altitudes, reduce the baking soda to 0.75 tbsp to prevent over-rising.
Store the cake in an airtight container at room temperature for up to 3 days, covered with plastic wrap. For longer storage, freeze slices wrapped individually for up to 3 months. The cake’s moisture content makes it ideal for layering with Hershey’s chocolate frosting or a dusting of powdered sugar. Reheat slices at 300°F for 5 minutes to restore fudgy texture. The single-bowl method minimizes cleanup—just one bowl, one mixer, and one pan to wash.
Why You'll Love This Recipe
- No Melted Mess: I swear by this method—just chop those dark chocolate bars into chunks and fold them straight into the batter. No tempering, no stress, and the chunks stay gloriously gooey in the middle while the edges get that perfect set. (Yes, even if you’re still learning how to bake.)
- Rich Without Bitterness: That 70% Hershey’s Especially Dark is the star here, but the sugar and butter balance it so well you won’t get that harsh aftertaste. It’s deep, fudgy, and just sweet enough to make you forget you’re eating something “healthy-ish.” Honestly, my kids don’t even know it’s dark chocolate—they just call it “mom’s secret cake.”
- Double-Duty Dessert: This cake keeps beautifully for days, so I make it on Sundays and portion it out for work snacks, date nights, or when my book club shows up unannounced. Slice it thin for a quick breakfast toast with peanut butter, or go full decadence with whipped cream. It’s the one dessert that actually lasts.
- Pantry Staple Magic: You’re already using things you have—flour, sugar, butter—and that single bar of Hershey’s stretches into a whole cake. No fancy ingredients, no last-minute grocery runs. I’ll be real: I’ve made this with expired flour (fine), forgotten the baking soda (oops, but still edible), and it’s never let me down. Reliable? Yes. A lifesaver? Absolutely.
Step-by-step instructions for Hershey's especially dark chocolate cake
A single-bowl method that delivers rich, fudgy layers with a moisture-locking secret.
Melt the Chocolate and Butter Together
Begin by chopping the 8 oz Hershey's Especially Dark Chocolate Bars into small, even pieces—this ensures consistent melting. Place them in a heatproof bowl set over a pot of simmering water, ensuring the bottom of the bowl never touches the water. Stir occasionally until the chocolate melts completely, then remove from heat.
Add the 1 cup Unsalted Butter to the melted chocolate and stir until fully combined. The mixture should be smooth with no visible butter chunks. Let it cool slightly—this prevents the butter from seizing when mixed with the buttermilk later. I like to work quickly here; the chocolate hardens fast once removed from heat.
Whisk Wet Ingredients to a Smooth Paste
In the same bowl, whisk in the 1.5 cups Granulated White Sugar until fully dissolved into the chocolate-butter mixture. Add the 1 cup Buttermilk and 1 tbsp Vanilla Extract, whisking vigorously until the batter is completely smooth. The buttermilk will thin the mixture slightly—this is normal and necessary for that signature moist texture.
Next, add the 0.25 cup Vegetable Oil and whisk again. The oil helps tenderize the cake while contributing to its rich, velvety crumb. If the batter looks curdled at this stage, don't worry—it will smooth out once the dry ingredients are incorporated. This is also the point where I add the 0.5 tsp Salt, ensuring even distribution throughout the wet mixture.
Combine Dry Ingredients for Maximum Moisture Retention
In a separate bowl, sift together the 2 cups All-Purpose Flour and 1 tbsp Baking Soda. The baking soda is our moisture-locking secret—it creates lift while preventing dryness. Whisk these dry ingredients thoroughly to eliminate any lumps, then gradually add them to the wet mixture in three additions, mixing just until combined after each.
I use a spatula for this step, folding gently to maintain air pockets without overmixing. Overmixing develops gluten, which can make the cake dense. The batter should be thick but pourable—if it seems too stiff, add 1-2 tablespoons of buttermilk to reach the perfect consistency. The goal is a smooth, velvety batter that holds its shape when dropped from a spoon.
Bake to Perfect Doneness for Maximum Moisture
Preheat your oven to 350°F and grease three 8-inch round cake pans with vegetable oil, then line the bottoms with parchment paper. Divide the batter evenly among the pans—this ensures even baking and level layers. Tap the pans gently on the counter to release any air bubbles that may have formed during mixing.
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs but no wet batter. The cake should spring back slightly when pressed in the center. I check at 25 minutes—if the edges brown too quickly, tent the pans with foil. Overbaking is the enemy of moisture; once the cake pulls away from the sides, it's time to remove it from the oven immediately.
Cool and Layer for Ultimate Richness
Allow the cakes to cool in their pans for 10 minutes, then transfer them to a wire rack to cool completely. This gradual cooling prevents cracking and ensures even layers. While they cool, prepare your frosting—whether it's a simple chocolate ganache or a rich cream cheese glaze. The contrast between the moist cake and the smooth frosting is what makes this recipe truly special.
Once fully cooled, level the tops if necessary and layer with your chosen frosting. For maximum moisture retention, I recommend brushing each layer with a simple syrup made from equal parts sugar and water, heated until dissolved. This step isn't mandatory but elevates the cake's tenderness. Serve slices at room temperature for the best texture—each bite should be rich, fudgy, and perfectly moist.
Pro Tips For Making Hershey'S Especially Dark Chocolate Cake
- Melt Chocolate Slowly: I learned this the hard way—dumping chopped chocolate bars into hot butter makes a greasy mess. Instead, melt the butter first, then reduce heat to medium-low and stir in the chocolate until it’s smooth but not boiling. This keeps the dark chocolate from seizing or turning grainy, which is especially important with Hershey’s Especially Dark—it’s already intense, and you don’t want texture issues ruining it.
- Sift the Flour Twice: Dark chocolate cakes are dense enough without clumps of flour weighing them down. After measuring, give the flour a quick sift right into the bowl, then sift again after adding the dry ingredients. This isn’t just about aeration—it’s about making sure the baking soda distributes evenly, so your cake rises properly instead of sinking in the middle.
- Skip the Overmixing: The moment you see streaks of flour in the batter, stop stirring. Overmixing develops gluten, which turns your rich chocolate cake into a tough, dense brick. Use a spatula to fold just until combined—yes, it’ll look lumpy, but that’s how you get a tender crumb. Trust me, your future self will thank you when you cut into it.
- Test for Doneness Early: This cake’s dark color tricks you into thinking it’s done before it is. Start checking with a toothpick at 28–30 minutes (depending on your oven). If it comes out with moist crumbs but no wet batter, it’s ready—even if the edges look set. Overbaking dries out the chocolate flavor, and that’s a crime when you’re using Hershey’s Especially Dark.
Serving suggestions for this hershey's especially dark chocolate cake
Chocolate Frosting Pairing
Nothing complements this cake like a Hershey's chocolate frosting made from ½ cup melted dark chocolate (same brand), ½ cup softened butter, and 2 cups powdered sugar. Whisk until smooth, then pipe between layers or spread on top.
For extra decadence, fold in ½ cup whipped cream for a lighter texture. I like to dust with cocoa powder for a professional finish. 🍫
Fresh Fruit Contrast
Add a bright contrast to the rich chocolate with strawberries or raspberries. Slice 1 cup strawberries and arrange them on top of the frosted cake. The natural sweetness cuts through the bitterness of the dark chocolate.
For a tropical twist, try mango slices or kiwi—their acidity balances the cake's richness perfectly. 🍓
Warm Spiced Whipped Cream
Heat 1 cup heavy cream with 1 tbsp brown sugar and ½ tsp cinnamon until steaming, then whip to soft peaks. This warm, spiced cream adds a cozy touch that pairs beautifully with the deep chocolate flavor. Serve immediately for the best texture and aroma. 🌟
Espresso or Coffee Drizzle
For a sophisticated touch, drizzle the cake with a chocolate-espresso glaze. Melt ½ cup dark chocolate with 2 tbsp strong coffee or espresso and 1 tbsp butter, then drizzle over the frosting.
The coffee enhances the chocolate's depth without overpowering it. This works especially well for adult gatherings. ☕
Crunchy Toppers
Add texture with toasted nuts or crushed cookies. Try ½ cup chopped pecans or Oreo crumbles sprinkled on top of the frosting. For a salty contrast, add flaky sea salt. These toppings create a delightful crunch that complements the cake's soft, fudgy interior. 🌰
Serving Temperature Tips
Serve this cake at room temperature for the best texture—chilled cake can become dry. If you must refrigerate, bring slices to room temperature for 10-15 minutes before serving.
For a warm twist, reheat slices in the microwave for 10 seconds to restore moisture. Store leftovers in an airtight container** to keep them fresh. 💡

Frequently asked questions
Why does this recipe use baking soda instead of baking powder?
The baking soda creates a chemical reaction with the buttermilk that locks in moisture and produces a tender, fudgy crumb—unlike baking powder, which creates more lift. This is the secret behind the cake's signature velvety texture.
Can I make this cake in a different pan size?
Yes! For a single 9-inch layer, reduce baking time to 20-25 minutes. For cupcakes, bake in a muffin tin for 18-22 minutes at 350°F. Always check doneness with a toothpick.
What if my cake cracks on top?
Cracking happens when the cake cools too quickly. Let it cool in the pan for 10 minutes before transferring, and avoid opening the oven door early. For a crackly top (like bakery-style), bake 2-3 minutes longer.
How do I store leftovers to keep them moist?
Wrap tightly in plastic wrap or store in an airtight container at room temperature for up to 3 days. For longer storage, freeze slices for 3 months. Reheat briefly in the microwave to restore moisture.
Can I substitute dark chocolate for milk chocolate?
Not recommended—the deep, intense flavor of Hershey's Especially Dark is key to this recipe. If you must use milk chocolate, reduce sugar by 0.25 cup to balance sweetness, but expect a lighter chocolate taste.
