Ingredients for hershey's chocolate chocolate cake
Twelve ingredients. Three decadent layers. Pockets of fudgy bliss in every bite—this is your ultimate Hershey's chocolate cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Hershey's Milk Chocolate Bars 🍫 | 12 oz | Melted for batter and gems |
| Hershey's Semi-Sweet Chocolate Chips 🍫 | 2 cups | Ensures signature Hershey's flavor |
| All-Purpose Flour 🌾 | 3 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 2 ½ cups | Balances sweetness perfectly |
| Unsalted Butter 🧈 | 2 cups | Room temperature for creaming |
| Large Eggs 🥚 | 4 whole | Room temperature for best mixing |
| Baking Powder 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Cocoa Powder 🍫 | ¾ cup | Dutch-processed for richness |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Whole Milk 🥛 | 1 cup | Warmed for best incorporation |
| Powdered Sugar 🍚 | 4 cups | For buttercream frosting |
| Heavy Whipping Cream 🥛 | 1 cup | Cold for stable buttercream |
| Unsalted Butter 🧈 | 1 cup | Room temperature for buttercream |
The chocolate matters most here. Hershey's Milk Chocolate Bars are non-negotiable—their signature taste defines this recipe. Grab the full-size bars, not the mini ones. Costco sells them in bulk, but any grocery store carries them. For the chocolate chips, Hershey's Semi-Sweet is essential (no substitutions here). The cocoa powder should be Dutch-processed for that deep, rich flavor—Hershey's Special Dark works perfectly. And don't skimp on the vanilla: Madagascar Bourbon from McCormick takes it to the next level. Pre-sift your flour and cocoa to avoid lumps, and always measure by weight if you're feeling fancy—it makes a noticeable difference.
No Hershey's chocolate bars? Nestlé Toll House Semi-Sweet Chips plus a bar of Guittard Chocolate can work in a pinch, but you'll lose that signature Hershey's punch. Dutch-processed cocoa unavailable? Natural cocoa plus 1/4 tsp baking soda mimics the flavor. For the buttercream, powdered sugar from Domino is my go-to—it's finely ground and dissolves smoothly. The heavy cream needs to be cold for stable peaks, so pull it out of the fridge just before whipping. And if you're worried about the cake being too dense, add 1/4 cup sour cream to the batter—it keeps it moist without compromising texture. The secret to those fudgy gems? Chop the melted chocolate bars into tiny pieces before folding them in.
This cake keeps beautifully—3 days at room temperature covered with plastic wrap, or 1 week refrigerated. For longer storage, freeze fully assembled layers (without frosting) for up to 3 months. The buttercream can be made a day ahead and refrigerated, then whipped back to fluffiness with a hand mixer. To assemble, let layers sit at room temperature for 30 minutes before frosting—they'll be easier to handle. And here's a pro tip: Chill the cake 1 hour before slicing so the frosting stays put. Trust me, it's worth the wait for that perfect slice.
Why You'll Love This Recipe
- No Mixer Needed: I melt the chocolate bars and butter together in one bowl—no fancy equipment, just a fork and a microwave. The Hershey’s chips fold right in, so you’re basically mixing while the cake’s baking, not before. Honestly, my blender’s been collecting dust since I tried this.
- Double Chocolate Bliss: That rich, molten center from the melted chocolate bars? It’s like biting into a warm milkshake. The semi-sweet chips add little bursts of texture, and the flour’s just enough to keep it tender—not dry, not cakey, but perfect. I’ll be real: I’ve made it three times in a week.
- Party in a Box: This cake’s my go-to for birthdays, potlucks, or when my book club votes for dessert. Slice it into squares, and it’s easy to share—no awkward portioning. Between us, I’ve even packed it for lunches (yes, even on a Tuesday), and no one’s ever complained.
- Budget-Friendly Luxury: You’re using pantry staples—flour, sugar, butter—and the Hershey’s bars stretch further than fancy chocolate. A single box of chips and two bars make two cakes, and leftovers? They freeze like a dream. My secret weapon for when I want to feel fancy without spending much.
Step-by-step instructions for Hershey's chocolate chocolate cake
This decadent triple-layered cake combines fudgy chocolate gems with ultra-moist layers—here's how to achieve bakery-quality perfection.
Melt Chocolate Bars and Prepare the Batter
First, chop the 12 oz Hershey's Milk Chocolate Bars into small pieces and place them in a heatproof bowl set over a pot of simmering water. Stir occasionally until completely melted and smooth—this should take about 5 minutes. Remove from heat and let cool slightly while you prepare the remaining ingredients.
In a separate large mixing bowl, cream together the 2 cups unsalted butter and 2.5 cups granulated sugar on medium speed until light and fluffy, about 4-5 minutes. This step is crucial for creating that signature tender crumb. Add the 4 whole large eggs, one at a time, mixing well after each addition. The mixture should nearly double in volume and become pale and airy.
Combine Dry Ingredients and Fold in Chocolate
In a medium bowl, whisk together the 3 cups all-purpose flour, 1.5 tsp baking powder, 0.75 cup cocoa powder, 0.5 tsp salt, and 2 tsp vanilla extract. Sift the dry ingredients directly into the wet mixture, alternating with the 1 cup whole milk, beginning and ending with the flour. Mix on low speed just until combined—overmixing develops gluten and makes the cake dense.
Remove the bowl from the mixer and gently fold in the melted 12 oz Hershey's Milk Chocolate Bars and 2 cups Hershey's Semi-Sweet Chocolate Chips using a silicone spatula. The batter will be thick and fudgy—this is exactly what we want. Divide the batter evenly among three 8-inch round cake pans lined with parchment paper.
Bake the Layers to Perfect Doneness
Preheat your oven to 350°F. Bake the cake layers for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs but no wet batter. The edges should be set, but the center should still have a slight bounce—this ensures a moist texture. Rotate the pans halfway through baking for even browning.
Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely. This gradual cooling prevents cracking and ensures clean slicing later. While the cakes cool, prepare the fudgy chocolate gems by melting 1 cup unsalted butter and 2 cups Hershey's Semi-Sweet Chocolate Chips together, then dropping spoonfuls onto parchment paper to set.
Prepare the Ultimate Chocolate Buttercream
In a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter until smooth and creamy, about 2 minutes. Gradually add the 4 cups powdered sugar, mixing on low speed until combined. Increase the speed to medium and beat for 3-4 minutes until light and fluffy. Add the 1 cup heavy whipping cream and 2 tsp vanilla extract, mixing until fully incorporated.
The buttercream should be thick enough to hold its shape but still pipeable. If it's too soft, chill the bowl for 10 minutes before proceeding. This buttercream is the star of the show—rich, velvety, and perfectly balanced with the cake's deep chocolate flavor.
Assemble and Decorate the Triple-Layered Cake
Place the first cake layer on a cake stand or plate and spread a generous layer of buttercream on top. Repeat with the remaining two layers, adding the fudgy chocolate gems between each layer for an extra burst of chocolatey goodness. Crumb coat the entire cake with buttercream, then chill in the refrigerator for 20 minutes to firm up.
Once chilled, apply the final layer of buttercream, smoothing it evenly with a spatula. Use a bench scraper to create clean edges and add any additional chocolate gems on top for a stunning presentation. Serve immediately for the most decadent experience, or refrigerate for up to 3 days for a cooler treat.
Pro Tips For Making Hershey'S Chocolate Chocolate Cake
- Melt Chocolate Slowly: Chop the Hershey’s bars into small, even pieces first—this prevents hot spots when melting. I learned this the hard way after one batch turned grainy; low heat and constant stirring keep everything smooth.
- Sift the Flour Twice: The recipe’s flour-to-sugar ratio is tight, so sift it before mixing to avoid dense layers. I skip this and end up with a cake that’s more brick than fluffy—don’t be like me.
- Don’t Overmix the Batter: Stir just until the dry ingredients disappear—overworking it makes the cake tough. After burning three batches, I finally figured out that a few lumps are better than a rubbery texture.
- Use Room-Temp Butter: Softened butter (not melted) blends better with the chocolate and sugar for a lighter crumb. I was skeptical until I tried it—now it’s non-negotiable for this recipe.
Common mistakes when making great hershey's chocolate chocolate cake
Overmixing the Batter
I've seen this happen more times than I can count—overmixing the batter turns your cake layers dense and tough instead of light and tender. Once you've incorporated all the dry ingredients and milk, mix for just 10-15 seconds on low speed.
The moment you see no more flour streaks, stop immediately. Overmixing develops gluten in the flour, which creates a chewy texture that defeats the purpose of this rich chocolate cake. 💫
Incorrect Chocolate Temperature
The melted chocolate bars need to cool slightly before folding them into the batter—around 110°F is ideal. If you add them too hot, they'll cook the eggs in the batter, creating a curdled mess.
I always let the melted chocolate sit for 5 minutes after removing it from heat before mixing. And never use microwave-melted chocolate—it burns easily and loses its smooth texture. Double boiler method only!
Underbaked or Overbaked Layers
Your cake layers need to be fully baked but still slightly springy to the touch. A toothpick should come out with a few moist crumbs, not wet batter or completely dry powder. Baking too long dries out the cake, while underbaking leaves it gummy.
I recommend baking for 25-30 minutes at 350°F and checking at the lower end of that range—ovens vary wildly! Rotate your pans halfway through for even baking.
Skipping the Cooling Step
Rushing to frost your cake while it's still warm is a recipe for disaster. The buttercream will melt and slide right off those warm layers. Always let your cakes cool completely in their pans for 10 minutes, then transfer to a wire rack for another 30 minutes.
This gradual cooling prevents cracking and ensures clean slices. Trust me, the 10-minute wait saves you from a frosting catastrophe. ⏰
Uneven Frosting Distribution
When spreading buttercream between layers, use a serrated knife or offset spatula to create an even layer—about ¼ inch thick. Too little frosting means gaps where chocolate gems will fall through, while too much creates a messy, uneven cake.
I like to use a bench scraper to create clean edges on the final frosting layer. And remember: less is more with the first crumb coat!
Ignoring the Fudgy Gems
Those little pockets of melted chocolate are what make this cake extraordinary, so don't skip them! The gems need to be fully set before assembling the cake—about 30 minutes at room temperature.
If you try to use them warm, they'll melt into your frosting instead of providing that surprise burst of chocolate. For extra decadence, add a few gems on top of the finished cake before serving. 🍫

Frequently asked questions
Can I substitute regular chocolate for Hershey's in this recipe?
The recipe relies on Hershey's signature flavor profile, but you can use Nestlé Toll House Semi-Sweet Chips plus a Guittard Milk Chocolate Bar as a substitute. For best results, use Dutch-processed cocoa powder like Hershey's Special Dark to maintain the rich chocolate taste. The texture may vary slightly without the exact Hershey's ingredients.
How do I make this cake without an electric mixer?
Use a sturdy wooden spoon or silicone spatula to cream the butter and sugar by hand for 5-7 minutes until light and fluffy. For the dry ingredients, whisk them together in a separate bowl, then gently fold into the wet mixture using a rubber spatula. The batter will be thicker, but the folding technique ensures proper integration of the chocolate.
Why did my cake turn out dense instead of moist?
Dense cake usually results from overmixing the batter or underbaking. Mix dry ingredients into wet just until combined (10-15 seconds on low speed), and bake until a toothpick comes out with moist crumbs (not wet batter). Also ensure your chocolate is cooled to 110°F before adding to prevent curdling the eggs.
Can I make this cake in a different pan size?
Yes, but adjust baking time accordingly. For 9-inch pans, bake 20-25 minutes at 350°F, and for 6-inch pans, bake 30-35 minutes. Divide the batter proportionally—three 9-inch layers would need slightly less batter, while six 6-inch layers would require more. Always check doneness with a toothpick.
How can I make this cake ahead of time?
Bake the layers 1 day ahead and store wrapped in plastic at room temperature. Frost the cake 4 hours before serving to allow flavors to meld. For longer storage, freeze fully assembled layers (unfrosted) for up to 3 months. Thaw overnight in the fridge before frosting and serving.
