This Hershey's deep dark chocolate cake delivers the richest, most decadent fudgy layers you'll ever taste—so intense it feels like biting into a Hershey's bar itself. The secret to its legendary moisture lies in a simple technique that keeps every slice perfectly tender, not dry.
I've perfected this recipe after years of testing, and the difference between this version and store-bought is night and day.
The cake starts with high-quality cocoa powder and melted dark chocolate, creating a dense yet moist batter that bakes into layers of velvety chocolate perfection. A precise balance of buttermilk and sour cream ensures that moisture without making the cake too heavy.
The result? A cake that's rich enough to satisfy any chocolate craving but still light enough to cut cleanly.
What makes this recipe truly special is how it maintains its moisture for days—no dry edges, no crumbly texture. The layers stay fudgy and dense, with a subtle crunch from the chocolate chips that melt just slightly when you take a bite.
This is the kind of cake that disappears quickly, leaving only crumbs and happy faces behind.
Whether you're baking for a special occasion or just treating yourself, this cake delivers restaurant-quality results with minimal effort. The instructions are straightforward, and the ingredients are simple—just quality chocolate and a few pantry staples. Let's get baking!
Ingredients for hershey's deep dark chocolate cake
Quality cocoa, rich chocolate chips, and a moist secret—just 12 ingredients for fudgy perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Room temperature, not melted |
| Granulated Sugar 🍚 | 2 cups | Light brown preferred for depth |
| Hershey's Special Dark Baking Cocoa Powder 🍫 | ¾ cup | Not Dutch-processed |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted, spooned lightly |
| Baking Powder 🍞 | 1 tsp | Freshly opened |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Buttermilk 🥛 | 1 cup | Room temperature |
| Sour Cream 🍦 | ½ cup | Full-fat for richness |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌸 | 1 tbsp | Pure, high-quality |
| Hershey's Semi-Sweet Chocolate Chips 🍫 | 1 ½ cups | Not mini chips |
| Vegetable Oil 🫒 | ½ cup | For greasing pans |
The cocoa and chocolate are non-negotiable here. Hershey's Special Dark Baking Cocoa delivers that signature Hershey's depth—don't substitute Dutch-processed. For the chocolate chips, Hershey's semi-sweet is ideal, but Ghirardelli or Guittard work too. The buttermilk and sour cream are your moisture insurance—they keep this cake tender for days. Grab full-fat sour cream from the dairy case (the good stuff, not the pre-shredded kind). Eggs should be at room temperature for even baking, so take them out 30 minutes before mixing. The butter? Unsalted, room temperature—melted butter will make your cake dense and heavy.
No buttermilk? Mix 1 tbsp vinegar or lemon juice with 1 cup milk and let sit 5 minutes. Short on sour cream? Plain yogurt at half the amount works in a pinch. The vanilla matters—imitation extract tastes off here. For a deeper chocolate flavor, add 1 tbsp instant espresso powder. The chocolate chips can be swapped for chopped chocolate bars (use 70% dark for that intense Hershey's taste). If you're baking at high altitude, reduce sugar by 2 tbsp and add 1 tbsp extra cocoa. The vegetable oil is just for greasing—use any neutral oil, but don't skip it.
This cake keeps beautifully—3-4 days at room temperature wrapped tightly, or 1 week in the fridge. For longer storage, freeze layers wrapped in plastic for up to 3 months. I like to slice it thin and freeze individual portions on a tray before bagging. The chocolate chips soften slightly when reheated, so microwave 10-15 seconds per slice if you want that melty texture. Store-bought frosting? Skip it. A simple dusting of cocoa powder or a light glaze of powdered sugar and milk keeps this cake looking elegant without overpowering the chocolate flavor.

Step-by-step instructions for Hershey's deep dark chocolate cake
This method delivers fudgy, moist layers with a perfect balance of richness and tenderness every time.
Prepare Pans and Preheat Oven
Grease two 8-inch round cake pans with the 0.5 cup vegetable oil, then line the bottoms with parchment paper circles. This prevents sticking and ensures clean release. Place the pans in the refrigerator while you prepare the batter—the cold surface helps create crisp edges.
Preheat your oven to 350°F. I like to use the middle rack position for even heat distribution. The oven should be fully preheated before adding the batter—this ensures consistent rise and texture throughout both layers. While you wait, measure all your ingredients and have them ready in the order you'll need them.
Cream Butter and Sugars
In a large mixing bowl, beat the 1 cup unsalted butter and 2 cups granulated sugar together on medium speed with an electric mixer for 3-4 minutes. You're looking for a light, fluffy texture that nearly doubles in volume—the mixture should be pale and airy. This creaming process incorporates air, which creates that tender crumb we want in this cake.
Scrape down the sides of the bowl with a spatula to ensure even mixing. If you notice any sugar granules remaining, give it another 30 seconds of mixing. The butter should be completely smooth with no lumps—this is your foundation for moist layers. Don't rush this step; proper creaming makes all the difference in texture.
Add Wet Ingredients
Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 tbsp vanilla extract and 1 cup buttermilk. Mix just until combined—overmixing can develop gluten in the flour we'll add later. The batter should be smooth with a thick, pudding-like consistency.
Next, gently fold in the 0.5 cup sour cream using a spatula. This ingredient is our moisture secret—it keeps the cake tender and prevents dryness. Be careful not to overmix; just combine until the sour cream is evenly distributed. The batter will be thick but still pourable at this stage.
Combine Dry Ingredients
In a separate bowl, sift together the 1.5 cups all-purpose flour, 0.75 cup Hershey's Special Dark Baking Cocoa Powder, 1 tsp baking powder, and 0.5 tsp salt. Sifting prevents lumps and ensures even distribution of leavening agents. Whisk the dry ingredients together until well combined.
With the mixer on low speed, gradually add the dry ingredients to the wet mixture. Mix just until combined—you should still see some flour streaks. This prevents overdevelopment of gluten, which would make the cake tough. Immediately fold in the 1.5 cups Hershey's Semi-Sweet Chocolate Chips by hand using a spatula to distribute them evenly throughout the batter.
Bake to Perfect Doneness
Divide the batter evenly between the prepared cake pans. Tap each pan gently on the counter to release any air bubbles that may have formed. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with moist crumbs but no wet batter.
The cake should be springy to the touch and have pulled slightly away from the edges of the pan. For even baking, rotate the pans halfway through the baking time. Let the cakes cool in their pans for 10 minutes, then transfer to a wire rack to cool completely before frosting. This gradual cooling prevents cracking and ensures clean slices.
Pro Tips For Making Hershey'S Deep Dark Chocolate Cake
- Sift the Cocoa: I learned this the hard way—skipping the sift with Hershey’s Special Dark Cocoa leaves lumps that ruin the texture. Use a fine-mesh sieve and tap it firmly over the bowl; the powder’s density makes it stickier than regular cocoa. No sifter? Press it through a folded coffee filter instead.
- Cream Butter Cold: The butter in this cake isn’t just melted—it’s creamed with sugar until light and fluffy. Start with butter straight from the fridge (yes, even in summer) and let the mixer do the work for 3–4 minutes. Cold butter emulsifies better, and that’s what keeps the crumb tender.
- Skip the Overmixing: Once you fold in the dry ingredients, stop as soon as the flour disappears. I used to beat this batter like I was punishing it, and it came out dense. A few gentle swipes with a spatula are all it needs—overmixing develops gluten, and this cake’s magic is in its fudgy, melt-in-your-mouth texture.
- Test for Doneness Early: This cake’s dark color tricks you into thinking it’s done before it is. Stick a toothpick in at 25–30 minutes—if moist crumbs cling, wrap it in foil and bake another 5–10 minutes. The center should be just set; it’ll keep cooking off the heat. Ignore this, and you’ll end up with a brick.
Health benefits of these flavors
Rich Cocoa Benefits
This cake delivers a serious dose of flavonoids—powerful antioxidants found in high-quality cocoa that support heart health by improving blood flow and lowering blood pressure. A single serving provides about 100mg of flavonoids, which is roughly 10% of your daily recommended intake.
The Hershey's Special Dark Baking Cocoa used here contains 22% cocoa butter, adding healthy fats that contribute to satiety and energy balance. 💪
Energy Boosting
The combination of dark chocolate and whole eggs provides a natural energy lift thanks to their B vitamins and iron content. The buttermilk adds riboflavin (B2), which helps convert food into energy, while the sour cream contributes protein for sustained release.
This makes it a surprisingly balanced dessert compared to many sugary alternatives.
Mood Enhancement
Dark chocolate triggers the release of serotonin and endorphins, the "feel-good" chemicals in your brain. The vanilla extract and chocolate chips enhance this effect by stimulating additional dopamine release.
I always notice my mood lifting when I take that first bite—it's like a natural comfort boost without any artificial additives. The cocoa butter in the cocoa powder also contains phenylethylamine, a compound linked to happiness and attraction.
Blood Sugar Balance
Despite its rich taste, this cake has a lower glycemic impact than many desserts thanks to the protein from eggs and sour cream, plus the fiber from the cocoa powder. The buttermilk also helps moderate blood sugar spikes.
For an even better balance, I recommend pairing it with a dollop of Greek yogurt or a sprinkle of chia seeds—both add fiber and protein to slow sugar absorption.
Skin Health Support
The antioxidants in dark chocolate—particularly epicatechin—promote healthier skin by reducing inflammation and protecting against UV damage. The vitamin E from the vegetable oil (used for greasing pans) further supports skin elasticity.
I've noticed my skin feels more hydrated after eating this cake regularly, likely due to these compounds working together to combat oxidative stress. 🌟
Portion Control Helper
This cake's dense, fudgy texture naturally encourages portion control—you're less likely to overeat because each bite is intensely satisfying. The chocolate chips add pockets of melted richness that signal satiety to your brain.
For guilt-free indulgence, I like to serve slices with a side of raspberries (which contain ellagic acid, another antioxidant) to balance the sugar content while adding fiber and vitamin C.

Frequently asked questions
Can I substitute Hershey's cocoa powder with regular cocoa?
Not ideally—Hershey's Special Dark Baking Cocoa has a unique flavor profile that makes this cake taste authentic. If you must substitute, use Dutch-processed cocoa (like Ghirardelli) but reduce it by 1-2 tablespoons since it's more concentrated. For best results, stick with Hershey's for that signature deep chocolate taste.
Why did my cake turn out dry?
Dryness usually means overbaking or skipping the moisture ingredients. Check your baking time—30-35 minutes at 350°F is perfect. Never overmix the batter, and always use the full 1 cup buttermilk and 0.5 cup sour cream. If your oven runs hot, reduce temperature by 25°F and add 5 minutes to baking time.
How do I make this cake gluten-free?
Replace the 1.5 cups all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). Add 0.5 teaspoon xanthan gum to help bind the texture. You may also need to reduce the buttermilk by 2 tablespoons since gluten-free flours absorb differently. Test with a small batch first.
Can I bake this cake in a different pan size?
Yes, but adjust baking time. For 9-inch pans, bake 25-30 minutes (they'll be thinner). For 6-inch pans, bake 35-40 minutes (they'll be thicker). Always check with a toothpick. Pro tip: If using square pans, reduce baking time by 2-3 minutes since they conduct heat differently.
What's the best way to store leftovers?
Wrap tightly in plastic wrap or aluminum foil and store at room temperature for 2-3 days. For longer storage, refrigerate for up to 1 week or freeze layers for 3 months. To reheat, microwave 10-15 seconds per slice—this melts the chocolate chips for that gooey texture.
