Ingredients for chocolate cake recipe on back of hershey's cocoa
Five core ingredients plus pantry staples transform into that nostalgic Hershey's chocolate cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Hershey's Special Dark Cocoa Powder 🍫 | ½ cup | Unsweetened, high-quality for rich flavor |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for even texture |
| Granulated White Sugar 🍚 | 1 ½ cups | Standard supermarket variety |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for proper mixing |
| Large Eggs 🥚 | 2 whole | Room temperature for even baking |
| Baking Powder 🍞 | 1 ½ tsp | Aluminum-free for best results |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain for even distribution |
| Vanilla Extract 🌸 | 1 tsp | Pure, high-quality extract |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Vegetable Oil 🫒 | ¼ cup | Light, neutral flavor |
| Hot Water 💧 | ½ cup | Just boiled, for proper cocoa activation |
| Powdered Sugar 🍚 | ½ cup | Optional, for dusting |
The Hershey's Special Dark Cocoa Powder is non-negotiable—it's what delivers that iconic, deep chocolate flavor. Store it in an airtight container away from light to prevent flavor degradation. For optimal results, use Hershey's brand directly from the bag, as other cocoa powders may yield different textures. The butter should be cold and cubed when measuring to ensure proper creaming. Kirkland Signature or Land O'Lakes work well for consistency. Sift the flour and baking powder together to eliminate lumps, which guarantees a smoother batter. King Arthur or Gold Medal brands are ideal for their reliable performance in baking.
No Hershey's cocoa? Nestlé or Dutch-process cocoa will work, but the flavor profile shifts slightly. Substitute 3 oz of melted dark chocolate for the cocoa and hot water if needed, though the texture becomes denser. Vegetable oil can be swapped for melted butter (same quantity), though the cake may darken slightly. Almond milk works in place of dairy milk, though the texture becomes slightly lighter. For the vanilla extract, McCormick or Nielsen-Massey brands are reliable choices. Pure vanilla extract (not imitation) is critical for authentic flavor. If you're dusting the cake, Domino or C&H powdered sugar are standard options, though confectioners' sugar from specialty stores offers finer texture.
The hot water must be freshly boiled and cooled to room temperature before mixing—this activates the cocoa powder properly. Store baked cake in an airtight container at room temperature for up to 4 days, though it's best enjoyed within 2 days for optimal moisture. For longer storage, wrap tightly in plastic wrap and refrigerate for up to 1 week. The cake freezes beautifully—slice before freezing and thaw at room temperature for 1-2 hours. Portion into individual servings before freezing to prevent a soggy texture upon thawing. Reheat slices in a 350°F oven for 5-10 minutes if desired, though the cake is delicious at room temperature.

Step-by-step instructions for Hershey's cocoa chocolate cake
This classic back-of-the-bag recipe delivers moist, rich chocolate cake with perfect texture every time.
Prepare the Cocoa Mixture
In a medium saucepan, combine the 0.5 cup Hershey's Special Dark Cocoa Powder, 1.5 cups Granulated White Sugar, 0.5 cup Milk, and 0.5 cup Hot Water. Bring to a gentle boil over medium heat, stirring constantly until the mixture thickens slightly. This step activates the cocoa powder and creates a smooth base for the batter.
Remove from heat and let cool for 2-3 minutes while you prepare the butter and eggs. The mixture should be warm but not hot to the touch—this prevents scrambling when combined with the eggs later. If it cools too much, gently reheat for 10-15 seconds to maintain the proper consistency.
Cream Butter and Eggs
In a large mixing bowl, cream together the 0.75 cup Unsalted Butter and 0.25 cup Vegetable Oil using an electric mixer on medium speed until light and fluffy, about 2-3 minutes. Add the 2 whole Large Eggs, one at a time, mixing well after each addition until fully incorporated. This step ensures proper aeration for a tender crumb.
Gradually add the cooled cocoa mixture to the butter-egg mixture, mixing on low speed until just combined. Scrape down the sides of the bowl as needed to ensure even mixing. The batter should be smooth with no visible streaks of cocoa powder. This gradual combination prevents the butter from melting and maintains the cake's structure.
Combine Dry Ingredients
In a separate bowl, whisk together the 1.5 cups All-Purpose Flour, 1.5 teaspoons Baking Powder, and 0.5 teaspoon Diamond Crystal Kosher Salt. Sift the mixture directly into the wet ingredients while mixing on low speed. This prevents lumps and ensures even distribution of leavening agents throughout the batter.
Add the 1 teaspoon Vanilla Extract and mix on low speed for an additional 30 seconds until just combined. Overmixing at this stage develops gluten, which can make the cake dense. The batter should be thick but pourable—similar to heavy pudding. If it appears too thick, add 1 tablespoon of milk to achieve the proper consistency.
Bake to Golden Perfection
Preheat your oven to 350°F. Pour the batter into a 9-inch round cake pan lined with parchment paper or lightly greased with butter. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The edges should be set, but the top may still appear slightly soft.
I recommend checking for doneness at the 25-minute mark, as ovens vary. The cake is done when it springs back slowly when gently pressed in the center. Remove from the oven and let cool in the pan for 10 minutes before transferring to a wire rack to cool completely. This gradual cooling prevents cracking and ensures even texture.
Dust with Powdered Sugar (Optional)
Once completely cooled, dust the top of the cake with 0.5 cup Powdered Sugar using a fine-mesh sieve. This step adds a classic touch and balances the rich chocolate flavor. For a more professional finish, you can also drizzle with a simple glaze made from 0.25 cup Powdered Sugar and 1 tablespoon Milk, but the dusting alone delivers that nostalgic back-of-the-bag charm.
The cake keeps well at room temperature for 2-3 days when stored in an airtight container. For best results, slice and serve at room temperature. Each slice should be moist, richly chocolatey, and perfectly tender—just like the classic recipe promises.
Pro Tips For Making Chocolate Cake Recipe On Back Of Hershey'S Cocoa
- Melt Butter Slowly: I learned this the hard way—dumping cold butter into hot sugar makes a greasy mess. Instead, melt the butter first, then let it cool just until it’s warm to the touch before mixing with sugar. The batter will be smoother, and you’ll avoid a cake that’s dense or oily.
- Sift the Flour Twice: The back-of-the-box recipe counts on you sifting that flour, but one pass isn’t enough. After mixing dry ingredients, give it a second sift straight into the bowl—this cuts lumps and guarantees even distribution. Trust me, your cake’s texture will thank you.
- Don’t Overmix the Batter: As soon as the flour disappears, stop stirring. I used to think extra mixing meant better blending, but this recipe is delicate—overworking the batter introduces air pockets that make the cake tough. Fold just until combined, like you’re tucking in a blanket.
- Rotate the Pan Mid-Bake: The oven’s hot spots are real, and this cake’s edges burn before the center sets. After 20 minutes, swap the pan front to back (or top to bottom if your oven runs that way). It’s a 10-second move that saves you from a brick-like cake.
Troubleshooting perfect results
Dense Instead of Moist
The most common issue is a cake that turns out dense rather than tender. This usually happens when the butter and eggs aren't properly creamed or if the dry ingredients are overmixed.
To fix this, cream the butter and oil together until light and fluffy—about 2-3 minutes—and mix the dry ingredients on low speed just until combined. Overmixing develops gluten, which makes the cake tough.
Also, ensure your hot water is fully cooled before combining with the cocoa mixture—adding it too hot can scramble the eggs. 💡
Cracked Top
A cracked top often results from sudden temperature changes or opening the oven too early. To prevent this, preheat your oven thoroughly to 350°F and avoid opening the door during the first 20 minutes of baking.
If cracks still appear, try baking in a water bath by placing your cake pan inside a larger roasting pan filled with 1 inch of hot water. This creates a steadier baking environment. Let the cake cool gradually in the pan for 10 minutes before transferring to a rack.
Sunken Center
A sunken center usually indicates underbaking or insufficient leavening. Double-check that you're using aluminum-free baking powder (like Clabber Girl) and that it's fresh—old baking powder loses potency. Also, ensure your oven is properly calibrated by testing it with an oven thermometer.
If your cake still sinks, try adding 1 extra tablespoon of baking powder or reducing the bake time by 2-3 minutes and checking for doneness earlier. 🌡️
Dry Texture
Dryness often occurs if the cake is overbaked or if the butter was melted instead of creamed. To avoid this, bake until a toothpick comes out with moist crumbs (not completely clean) and remove the cake immediately when done.
For extra moisture, add 1 tablespoon of milk or vegetable oil to the batter if it seems too thick.
Store the cake in an airtight container with a slice of bread to help retain moisture, or brush warm slices with a simple syrup made from 2 tablespoons sugar and 2 tablespoons water.
Uneven Baking
If the edges cook faster than the center, your oven may have hot spots or uneven heat distribution. Rotate the cake pan halfway through baking (after 15-17 minutes) for even cooking.
For a more even result, use an oven thermometer to confirm your oven's accuracy—many home ovens run 25°F hotter or colder than set. If your oven has hot spots, place a baking sheet on the lower rack during baking to deflect heat upward. 🔥
Flat Cake
A flat cake often results from overmixing the batter or insufficient leavening. To fix this, fold the dry ingredients into the wet mixture gently on low speed just until combined. Ensure you're using fresh baking powder (test by mixing 1 teaspoon with 2 tablespoons hot water
If your cake still flattens, try adding ½ teaspoon extra baking powder or using cake flour (which has a lower protein content) instead of all-purpose flour. Also, avoid overfilling the pan—batter should reach about ⅔ full of a 9-inch pan.

Frequently asked questions
Why does this recipe use hot water instead of cold?
The hot water activates the cocoa powder for maximum flavor and smoothness. When combined with sugar, it creates a silky base that blends perfectly with the butter and eggs. This technique is key to that classic Hershey's texture—without it, the cake can taste slightly bitter or grainy.
Can I make this cake in a different pan size?
Yes, but adjust the baking time. For an 8-inch pan, bake 25-30 minutes (check at 22 minutes). For a 10-inch pan, bake 35-40 minutes. The cake should always be tested with a toothpick—never rely solely on time. A 9-inch pan gives the best texture for this recipe.
What's the best way to store leftovers?
Wrap individual slices in plastic wrap or store the whole cake in an airtight container at room temperature for up to 3 days. For longer storage, freeze slices (thaw at room temperature) or refrigerate for 1 week. Add a slice of bread to the container to help maintain moisture. Reheat in a 350°F oven for 5 minutes if desired.
Why does my cake turn out dry?
Overbaking or melted butter (instead of creamed) causes dryness. Always bake until a toothpick comes out with moist crumbs, not clean. For extra moisture, add 1 tablespoon milk or oil if the batter seems too thick. Store in an airtight container with a slice of bread to prevent drying.
Can I substitute vegetable oil for butter?
Yes, but use the same quantity (0.75 cup total). The texture stays moist, though the cake may darken slightly. For richer flavor, use 0.5 cup butter + 0.25 cup oil. Never omit butter entirely—it's essential for that classic Hershey's richness.
