Ingredients for hershey's chocolate cake icing
Five pantry staples transform into that signature Hershey's chocolate cake icing with fudgy swirls and velvety smoothness.
| Ingredient | Amount | Notes |
|---|---|---|
| Hershey's Semi-Sweet Chocolate Bars 🍫 | 8 oz | High-quality chocolate for rich flavor |
| Unsalted Butter 🧈 | ½ cup | Cold, cut into small cubes |
| Powdered Sugar 🍚 | 3 cups | Sifted for smooth texture |
| Heavy Whipping Cream 🥛 | ¼ cup | Cold, for swirling consistency |
| Vanilla Extract 🌿 | 1 tsp | Pure alcohol-free preferred |
The chocolate is the star—Hershey's Semi-Sweet Bars deliver that iconic flavor, but Ghirardelli or Lindt work too if you want extra richness. Grab a full bar (not chips) for better melting. Butter matters here—unsalted, cold cubes melt evenly without seizing. Powdered sugar should be sifted before mixing to avoid lumps; Diamond Crystal is my go-to because it's finer than generic brands. The cream? Cold and heavy—none of that ultra-pasteurized stuff. If you can't find heavy cream, half-and-half works in a pinch, but the texture won't be as silky.
No Hershey's bars? Substitute with 6 oz of high-quality dark or milk chocolate, but reduce powdered sugar to 2.5 cups to balance sweetness. Butter out of stock? Vegetable shortening mimics the texture, though it lacks flavor. Vanilla extract can be swapped for 1 tsp vanilla bean paste if you're feeling fancy. For a lighter icing, add 1-2 tbsp milk or cream gradually until it reaches drizzling consistency. Pro tip: If your icing gets too thick, microwave in 10-second bursts—it reheats beautifully. Too thin? Dust in more powdered sugar, a tablespoon at a time.
This icing is a dream to store—refrigerate in an airtight container for up to 1 week, or freeze for 3 months in portions. For swirling, chill the icing slightly before piping—it holds its shape better. Leftovers? Perfect for topping brownies or stuffing cupcakes. If it hardens, pop it in the microwave for 15-20 seconds to soften. Trust me, the first time you drizzle this over a warm cake, you'll never go back to store-bought again.

Step-by-step instructions for Hershey's chocolate cake icing
This silky, fudgy icing transforms ordinary cake into decadent perfection—rich, velvety, and effortlessly professional.
Melt the Chocolate and Butter Together
Line a medium heatproof bowl with plastic wrap, pressing it directly against the sides to create a seal. Place this bowl over a saucepan filled with about 2 inches of simmering water, ensuring the bottom of the bowl doesn't touch the water. This is called a double boiler, and it's the secret to perfectly smooth chocolate.
Break the 8 oz Hershey's Semi-Sweet Chocolate Bars into rough chunks and add them to the bowl along with the 0.5 cup Unsalted Butter, cut into small cubes. Stir gently with a silicone spatula, watching as the chocolate and butter melt together over medium-low heat. You'll know it's ready when the mixture is completely smooth and glossy, with no visible streaks of chocolate. This should take about 8-10 minutes—be patient, as rushing this step can lead to grainy icing.
Whisk in Powdered Sugar and Vanilla
Remove the bowl from the heat and let the chocolate mixture cool slightly for 2-3 minutes. This prevents the powdered sugar from clumping when added. Sift the 3 cups Powdered Sugar directly over the chocolate mixture to avoid clumps, then whisk vigorously until fully incorporated.
Add the 1 tsp Vanilla Extract and continue whisking until the icing reaches a thick, spreadable consistency. It should coat the back of a spoon smoothly but still hold its shape when drizzled. If it's too thick, add 1 tablespoon of warm water at a time until you achieve the perfect balance—this icing should be thick enough to pipe but thin enough to swirl beautifully.
Incorporate the Heavy Whipping Cream
In a separate bowl, whip the 0.25 cup Heavy Whipping Cream with a hand mixer until soft peaks form. This step is crucial for adding airiness and creating those signature swirls. Gently fold the whipped cream into the chocolate mixture using a spatula, being careful not to deflate the cream. You want to maintain those soft peaks while blending everything together seamlessly.
Continue folding until the icing is completely smooth and uniform in color. The final texture should be thick, glossy, and just slightly thinned by the cream—like a luxurious fudge sauce. Taste a small spoonful and adjust sweetness if needed; you can add a pinch more powdered sugar if desired, but the original recipe is perfectly balanced for most palates.
Cool and Prepare for Decorating
Transfer the icing to a clean bowl and cover it tightly with plastic wrap, pressing the wrap directly onto the surface to prevent a skin from forming. Refrigerate for at least 30 minutes to allow the icing to thicken slightly and become easier to work with. This cooling step also enhances the flavors, letting the chocolate and vanilla meld together beautifully.
Once chilled, the icing should be thick enough to hold its shape when piped but still smooth enough to swirl effortlessly. Use it to frost your cake layers, create elegant drizzles, or fill piping bags for decorative rosettes. The contrast between the warm cake and this cool, velvety icing is what makes this recipe truly special—each bite delivers that perfect balance of rich chocolate and sweet creaminess.
Pro Tips For Making Hershey'S Chocolate Cake Icing
- Melt Chocolate Slowly: I learned this the hard way—dumping chopped Hershey’s bars into a pot of simmering butter makes the butter burn before the chocolate melts. Instead, drop the chopped bars into a heatproof bowl set over barely simmering water (about 170°F), stirring every 30 seconds. The chocolate melts evenly without scorching, and the butter stays golden.
- Use Room-Temp Butter: Cold butter in this icing is a nightmare—it fights you every time you try to mix. Take the butter out of the fridge 30 minutes before starting, or even better, let it sit in a warm (not hot) water bath for 10 minutes. Smooth, creamy icing every time, no extra elbow grease required.
- Whip Cream to Stiff Peaks: Skipping this step turns your icing into a sad, runny mess. Use a chilled bowl and beat the heavy cream until it holds soft peaks, then add vanilla. Keep whipping until it forms stiff peaks—yes, it’ll look like frosting, not liquid. The texture stays stable even in warm rooms, and it pipes beautifully.
- Sift Powdered Sugar Twice: Lumpy icing is the worst. Sift the powdered sugar before mixing, then sift it again right before combining with the melted chocolate-butter mixture. This cuts through any hidden grit and ensures a silky finish. (Trust me, you’ll taste the difference.)
Dietary considerations for hershey's chocolate cake icing
Gluten-Free Adaptation
To make this icing gluten-free, simply replace the powdered sugar with 1 cup granulated sugar and 2 cups gluten-free powdered sugar blend (like Bob's Red Mill). The texture will be slightly less smooth, but it still delivers that signature Hershey's flavor.
For extra richness, add 1 tbsp corn syrup to help bind the ingredients together. Always double-check your gluten-free powdered sugar label—some brands contain additives that may not be safe for strict gluten-free diets. 🌱
Dairy-Free Version
Swap the unsalted butter for ½ cup dairy-free margarine (like Earth Balance) or ½ cup coconut oil (solid, not melted). For the heavy whipping cream, use ½ cup full-fat coconut cream (chilled overnight) or ¼ cup dairy-free whipped topping (like Reddi-wip Dairy-Free).
The coconut cream adds a subtle tropical note that pairs surprisingly well with chocolate. If using coconut oil, ensure it's solid to mimic butter's texture. 🥥
Lower Sugar Options
Reduce the powdered sugar to 2 cups and add ½ cup unsweetened cocoa powder (like Hershey's Special Dark) to intensify the chocolate flavor without extra sugar. For a lighter touch, replace ¼ cup of the powdered sugar with ¼ cup monk fruit sweetener (like Lakanto).
The icing will be slightly less sweet but still rich and decadent. Taste as you go—you may need to add a pinch of salt to balance the flavors. 💯
Vegan-Friendly Swaps
For a fully vegan icing, melt 8 oz vegan chocolate bars (like Enjoy Life) with ½ cup coconut oil instead of butter. Use 3 cups vegan powdered sugar (like Wholesome Sweeteners) and ¼ cup plant-based milk (like almond or oat) to thin as needed.
Replace the heavy whipping cream with ¼ cup coconut cream (whipped until soft peaks form). The result is a luscious, plant-based icing that's just as velvety and rich. 🌿
Nut-Free Considerations
This recipe is naturally nut-free, but always verify that your Hershey's chocolate bars, powdered sugar, and vanilla extract are processed in nut-free facilities if allergies are a concern. For extra safety, use name-brand ingredients with clear labeling.
If you're baking for someone with severe allergies, consider making the icing in a dedicated nut-free kitchen or using pre-packaged nut-free chocolate like Guittard. 🚫🌰
Keto-Friendly Adjustment
Transform this icing into a keto-friendly treat by omitting the powdered sugar entirely and using ½ cup erythritol or monk fruit sweetener (like Swerve) instead. Add 2 tbsp unsweetened cocoa powder to deepen the chocolate flavor.
The butter and heavy cream can stay as-is, but reduce the cream to 2 tbsp to cut carbs further. The result is a low-carb, high-fat icing that's perfect for keto desserts. Just be mindful—this version will be much sweeter than the original! 🥬

Frequently asked questions
Can I use chocolate chips instead of Hershey's bars?
No, chocolate chips won't work—they contain stabilizers that prevent smooth melting. Use 8 oz of high-quality chocolate bars (like Ghirardelli) instead, broken into chunks for even melting. The bars give you that signature Hershey's flavor without graininess.
Why did my icing turn grainy?
Graininess usually happens when chocolate overheats or powdered sugar isn't sifted. Always use a double boiler and keep heat medium-low. Sift the powdered sugar first, and whisk constantly when combining it with melted chocolate to prevent clumps.
How do I adjust the thickness for different uses?
For piping decorations, chill the icing longer (up to 1 hour) to thicken. Too thick? Add 1 tbsp warm water at a time. For drizzling, thin with 1 tsp milk or cream until it flows smoothly but doesn't drip excessively. The ideal consistency coats a spoon but holds its shape when drizzled.
Can I make this icing ahead of time?
Store it in an airtight container in the fridge for up to 1 week. To reuse, microwave in 10-second bursts until smooth. For freezing, portion into small containers for up to 3 months—thaw overnight in the fridge before using.
What's the best way to swirl it through cake layers?
Chill the icing slightly before piping—it should be thick enough to hold its shape. Use a piping bag with a star tip to create elegant swirls. Spread a thin layer of cake batter on each layer first, then pipe the icing in zigzags before stacking. The contrast of dark icing against light cake creates stunning marbling.
