Ingredients for hershey's perfectly chocolate cake
Eight essential ingredients transform into a decadent cake with a secret moisture trick.
| Ingredient | Amount | Notes |
|---|---|---|
| Hershey's Milk Chocolate Bars 🍫 | 8 oz | Semi-sweet or milk chocolate, chopped |
| All-Purpose Flour 🌾 | 2 cups | Sifted, spooned lightly |
| Granulated Sugar 🍚 | 2 cups | White sugar preferred |
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat |
| Buttermilk 🥛 | 1 cup | Room temperature, unsweetened |
| Sour Cream 🥛 | ½ cup | Full-fat for richness |
| Baking Soda 🍃 | 1 tsp | Pure baking soda |
| Vanilla Extract 💧 | 2 tsp | Pure vanilla preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vegetable Oil 🫒 | ¼ cup | Light or canola oil |
| Hot Water 💧 | ¼ cup | Freshly boiled |
The Hershey's chocolate bars are non-negotiable for that signature flavor. Buy the full-size bars—they melt more evenly than the mini versions. Trader Joe's often has them at a discount, and Costco sells them in bulk. Chop them into even pieces (about 1/2-inch squares) so they distribute throughout the batter. The butter matters too—use full-fat, unsalted for maximum richness. If your butter is cold, microwave it for 20 seconds to soften, but don't melt it completely. For the buttermilk, if you forget to buy it, mix 1 tbsp lemon juice or vinegar with 1 cup milk and let it sit for 5 minutes.
No buttermilk? Substitute with 1 cup plain yogurt—it works in a pinch. Short on sour cream? Substitute with an extra 1/4 cup milk, though the texture won't be quite as moist. For the chocolate, semi-sweet or milk chocolate both work, but avoid dark chocolate—it's too bitter for this recipe. The hot water trick is key: it activates the baking soda for maximum lift. If you're worried about overmixing, use a hand mixer on low speed or fold by hand. And if you don't have vanilla extract, imitation vanilla works but lacks depth.
This cake stays moist for 5 days when wrapped tightly in plastic. For longer storage, freeze it for up to 3 months—thaw at room temperature before serving. The chocolate chunks keep it interesting, so don't skip chopping them. If you want to make it ahead, bake the cake, cool it completely, then wrap it. The flavor actually improves over time, especially if you add a layer of chocolate ganache before wrapping. For serving, a dusting of powdered sugar or a drizzle of melted chocolate elevates the presentation without overpowering the rich chocolate flavor.

- Rich Without Effort: That melted chocolate? It’s the secret weapon. The buttermilk keeps it moist, but the real star is how the sugar and butter create this perfectly tender crumb—no dry, dense mess here. One bite and you’ll forget it was this easy to make.
- Birthday or Breakfast: Serve it warm with ice cream for a crowd-pleasing centerpiece, or cut into squares for a grab-and-go breakfast that’ll actually fill you up. (Yes, I’ve done both—no judgment.) The chocolate flavor is so bold it works at any time of day.
- Budget-Friendly Indulgence: A whole cake for under $10? That’s right. Hershey’s bars stretch further than you’d think, and the rest of the ingredients are basics. Plus, leftovers? They disappear faster than I can say “second slice.”
Step-by-step instructions for Hershey's perfectly chocolate cake
Follow this one-bowl method for a rich, fudgy chocolate cake with a secret moisture boost.
👨🍳 Step 1: Melt Chocolate and Butter Together
Place the 8 oz Hershey's Milk Chocolate Bars and 1 cup Unsalted Butter in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until completely melted and smooth. The mixture should reach 140°F—this ensures the chocolate melts evenly without burning. Let it cool slightly for 2 minutes while you prepare the dry ingredients.
Real talk: Don't rush this step. If the chocolate cools too much before mixing, the cake will develop a grainy texture. The butter should be fully melted but not hot—just warm enough to blend seamlessly with the chocolate. This creates the rich, velvety base that makes this cake perfect.
🍳 Step 2: Combine Wet Ingredients
In the same bowl, whisk in 2 cups Granulated Sugar, 1 cup Buttermilk, 0.5 cup Sour Cream, 2 tsp Vanilla Extract, and 0.25 cup Vegetable Oil. Mix until the sugar dissolves completely and the batter appears smooth. The buttermilk and sour cream will thicken the mixture slightly—this is normal and essential for that moist crumb.
Here's the thing—adding the hot water later creates steam during baking, which keeps the cake ultra-moist. But first, we need to get the wet ingredients perfectly blended. I like to mix on medium speed for 30 seconds to ensure everything combines evenly. The batter should be thick but pourable at this stage.
👨🍳 Step 3: Sift and Fold Dry Ingredients
In a separate bowl, whisk together 2 cups All-Purpose Flour, 1 tsp Baking Soda, 0.5 tsp Salt, and 0.25 cup Hot Water. The hot water activates the baking soda immediately, creating tiny air pockets that lighten the cake. Sift the dry ingredients directly into the wet mixture, then gently fold with a spatula until just combined.
Don't overmix—you should still see some flour streaks. The secret to this cake's texture lies in the gentle folding technique. Overmixing develops gluten, which makes the cake tough instead of tender. The batter will be thick and fudgy-looking, which is exactly what we want for that rich, dense texture.
🔥 Step 4: Bake Until Golden and Springy
Pour the batter into a 9-inch round cake pan lined with parchment paper. Bake at 350°F for 30-35 minutes, until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter). The edges should be golden brown, and the cake should spring back slightly when pressed in the center.
I know it seems weird, but trust me—this cake is done when it's still slightly underbaked in the middle. The residual heat will finish cooking it as it cools, ensuring that perfect moist crumb. If you bake it until fully dry in the center, you'll end up with a dense, dry cake instead of the tender, fudgy texture we're after.
⏰ Step 5: Cool and Serve with Confidence
Remove the cake from the oven and let it cool in the pan for 10 minutes, then transfer to a wire rack to cool completely. The cooling process is crucial—it allows the moisture to distribute evenly throughout the cake. Serve slices at room temperature for the best texture and flavor.
This cake delivers on its promises: rich, fudgy layers with a moist crumb that melts in your mouth. The Hershey's chocolate shines through in every bite, and the secret moisture boost from the hot water keeps it tender for hours. Store leftovers covered at room temperature for up to 3 days—though I doubt they'll last that long!
Pro Tips For Making Hershey'S Perfectly Chocolate Cake
- MELT CHOCOLATE SLOW: I learned this the hard way—dumping chopped Hershey’s bars into hot butter makes seizing happen faster than you can say "soggy cake." Instead, melt the butter first, then remove it from heat and sprinkle in the chocolate a few pieces at a time, letting it melt gradually. This keeps the batter smooth and rich, not grainy.
- SIFT THE FLOUR: Skipping this step is how you end up with a cake that’s dense as a brick. The Hershey’s recipe relies on buttermilk and melted chocolate for moisture, so the flour needs to be light and aerated. Sift it directly into the dry ingredients—don’t just dump it in—and give it a quick whisk. It makes a real difference in texture.
- DON’T OVERMIX: I used to beat this batter like I was punishing it, and every time, the cake turned out tough and dry. Once the wet and dry ingredients come together, mix just until combined—maybe 10-12 strokes with a spatula. Overmixing develops gluten, and this cake isn’t supposed to be a bread.
- BAKE UNTIL SPRINGY: The recipe says "until a toothpick comes out clean," but that’s not always the case with chocolate cakes—they can be moist but still done. Press the center gently: if it springs back slowly, it’s ready. If it’s still jiggly after 5 minutes past the recipe’s time, cover it loosely with foil and let it rest. Patience here keeps it from drying out.
Wine and beer pairings for this hershey's perfectly chocolate cake
Rich Chocolate Wines
For this decadent chocolate cake, a Cabernet Sauvignon from Napa Valley is my go-to choice. The bold tannins and dark fruit notes—think blackberry and plum—complement the deep Hershey's chocolate flavor beautifully. I recommend a 2018 Robert Mondavi Reserve Cabernet for its smooth finish that won't overpower the dessert. 🍷
If you prefer something slightly sweeter, a Port-style wine like Graham's Six Grapes bridges the gap between wine and dessert. The caramel and chocolate undertones enhance the cake's richness without competing. Serve slightly chilled to let the flavors shine.
Creamy Dessert Beers
A Belgian-style dubbel like Westmalle Dubbel pairs surprisingly well with chocolate cake. The malty sweetness and spiced notes from coriander and licorice balance the Hershey's chocolate perfectly. The beer's slight bitterness cuts through the richness, creating a delightful contrast. 🍺
For a lighter option, try a Belgian witbier such as Hoegaarden. The citrusy notes from orange peel and coriander add a refreshing twist that cleanses your palate between bites. The effervescence also helps balance the cake's density.
Coffee Pairings
If you're serving this cake after dinner, a dark roast coffee with chocolate notes—like Starbucks Sumatra—elevates the experience. The low acidity and deep cocoa undertones mirror the Hershey's flavor, creating a harmonious finish. Brew it slightly stronger than usual to complement the cake's richness.
For an espresso-based option, try a chocolate mocha made with Valrhona cocoa powder. The intense chocolate flavor enhances the cake's depth, making every bite feel like a luxurious treat. Serve with a dollop of whipped cream for extra indulgence.
Creamy Liqueur Finishes
A splash of Baileys Irish Cream on the side adds a velvety finish that pairs perfectly with the cake's texture. The buttery caramel and vanilla notes enhance the Hershey's chocolate, creating a dessert-like experience even when enjoyed separately. 🍫
For a lighter touch, Godiva Chocolate Liqueur offers a sophisticated pairing. Its rich cocoa and vanilla flavors mirror the cake's ingredients, making each bite feel like a decadent moment. Serve it in small glasses alongside the cake for an elegant touch.

Frequently asked questions
Can I make this cake without buttermilk?
If you don't have buttermilk, mix 1 tablespoon lemon juice or vinegar with 1 cup milk and let it sit for 5 minutes until thickened. For an even richer texture, substitute with 1 cup plain yogurt. The cake will still turn out moist, though the crumb may be slightly denser.
Why does this recipe use hot water?
The hot water activates the baking soda immediately, creating tiny air pockets that make the cake lighter and more tender. It also generates steam during baking, which keeps the cake ultra-moist. This is the secret behind the perfect fudgy texture! Without it, the cake might turn out drier.
How do I prevent the cake from cracking?
Cracking usually happens when the cake cools too quickly. Let it cool in the pan for 10 minutes before transferring to a wire rack, and avoid opening the oven door too early. Also, don't overmix the batter—just fold the dry ingredients until combined. If cracks appear, cover them with a simple chocolate ganache or dust with powdered sugar.
Can I use dark chocolate instead of Hershey's milk chocolate?
Not ideal for this recipe, as dark chocolate has a more bitter, intense flavor that can overpower the delicate balance of ingredients. Stick with Hershey's milk or semi-sweet chocolate bars for that classic, rich taste. If you must use dark chocolate, reduce the amount to 6 oz and add 2 oz of milk chocolate to maintain the right flavor profile.
How long will this cake stay fresh?
When stored properly in an airtight container at room temperature, this cake stays moist and delicious for up to 5 days. For longer storage, freeze it for up to 3 months. Thaw at room temperature before serving. The secret moisture trick ensures it doesn't dry out quickly!
