Desserts
This Hershey dark chocolate icing recipe delivers the perfect velvety drizzle you’ve been searching for—smooth, glossy, and rich enough to elevate any dessert. The secret lies in tempering the chocolate properly and balancing butter and powdered sugar for that signature drip consistency without graininess.
I’ve perfected this over years of baking, and it’s become my go-to for cakes, cupcakes, and even drizzling over fruit.
What sets this recipe apart is its foolproof technique for achieving that restaurant-quality finish. You’ll need just five ingredients—Hershey dark chocolate, butter, powdered sugar, vanilla, and a pinch of salt—to create a sauce that’s both spreadable and drizzling, depending on how you use it.
The key is melting the chocolate gently and whisking in the butter gradually to avoid seizing.
By the time you’re done, you’ll have a luxuriously glossy icing that clings beautifully to cakes, coats cupcakes in a glossy sheen, or pools elegantly over strawberries. It stays fresh in the refrigerator for up to a week, making it ideal for prepping ahead.
The flavor is deep, slightly bitter, and perfectly balanced with vanilla—no aftertaste, just pure chocolate satisfaction.
This icing works equally well as a frosting substitute, a decorative drizzle, or even a filling for cookies. For extra flair, add a splash of espresso powder or orange zest to enhance the chocolate’s complexity.
Let’s get started—your desserts are about to look (and taste) like they came from a professional bakery.
Ingredients for hershey dark chocolate icing
Five ingredients transform into a velvety chocolate masterpiece—no fancy tools required.
| Ingredient | Amount | Notes |
|---|---|---|
| Hershey's Special Dark Chocolate Bars 🍫 | 8 oz | High cocoa content preferred |
| Unsalted Butter 🧈 | ½ cup | Cold, cut into small cubes |
| Powdered Sugar 🍚 | 2 cups | Sifted for smooth texture |
| Pure Vanilla Extract 🌿 | 1 tsp | High-quality, not imitation |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | Fine grain preferred |
| Heavy Cream 🥛 | ¼ cup | Optional for extra gloss |
The chocolate is non-negotiable. Hershey’s Special Dark bars melt beautifully but Ghirardelli 60% or higher takes this to next-level richness. I buy mine in bulk from Costco—cheaper and lasts forever. Skip the chips; bars melt smoother. Butter matters too—European-style like Plugrá stays firm longer when cutting into cubes. Powdered sugar? Domes brand dissolves best, but any sifted sugar works. Pro tip: keep your workspace cool while melting to avoid seizing.
No Hershey’s? Ghirardelli or Lindt 50% dark works in a pinch—just melt gently. Butter short on time? Shortening like Crisco keeps it stable at room temp. Powdered sugar clumping? Sift it again or swap for confectioners' sugar (same thing). The vanilla extract? Bourbon-infused adds depth if you’re feeling fancy. Heavy cream optional but whipped lightly gives that signature glossy finish. Want extra flavor? Espresso powder or orange zest (½ tsp each) elevates it instantly.
This icing stays fresh for 1 week in the fridge, covered tightly. For longer storage, freeze in 1-tbsp portions—thaw at room temp for 10 minutes before using. Reheat gently in 10-second bursts if it thickens. The secret to that perfect drip? Warm the bowl slightly before drizzling—chocolate flows like silk. Double batch and store; you’ll be glad you did.

Step-by-step instructions for Hershey dark chocolate icing
Here's how to create a perfectly smooth, velvety chocolate icing that drips like a dream.
Melt the Chocolate and Butter Together
Place the 8 oz Hershey's Special Dark Chocolate Bars and 0.5 cup Unsalted Butter (cut into small cubes) in a heatproof bowl set over a pot of simmering water. Keep the heat at a gentle simmer—you want the water to create steady, even warmth without boiling. Stir occasionally until the chocolate and butter melt completely, creating a glossy, thick mixture. You'll know it's ready when the chocolate has fully dissolved and the mixture looks smooth and shiny, with no streaks of unmelted chocolate.
Remove the bowl from the heat immediately to prevent overheating. Let the mixture cool slightly for about 5 minutes—it should be warm to the touch but not hot. This step is crucial because overheating can cause the chocolate to seize later when combined with powdered sugar. If you're using the optional 0.25 cup Heavy Cream, now's the time to whisk it in gently for extra richness and gloss.
Whisk in Powdered Sugar Gradually
Sift the 2 cups Powdered Sugar into the warm chocolate mixture to avoid clumping. Begin whisking slowly to combine, then gradually increase speed to medium-high. The powdered sugar should dissolve completely, creating a thick, smooth paste. If you encounter any lumps, stop whisking and gently press them against the side of the bowl with a spatula before continuing to whisk. The icing should thicken as you work, but not become grainy—this is where patience pays off.
Here's the thing—if the icing feels too thick at this stage, don't panic. We'll adjust the consistency in the next step. Keep whisking until the mixture is completely smooth and free of any sugar particles. The texture should resemble thick pudding but still be pourable. If you're using a stand mixer, attach the paddle attachment and mix on medium speed for about 2 minutes to ensure everything is fully incorporated.
Season and Adjust Consistency
Add the 1 tsp Pure Vanilla Extract and 0.25 tsp Diamond Crystal Kosher Salt to the chocolate mixture. Whisk vigorously for about 30 seconds to fully distribute the flavors. The salt enhances the chocolate's depth, while the vanilla adds a subtle, aromatic sweetness that balances the richness. Taste a small spoonful—if it needs more sweetness, add a bit more powdered sugar, 1 tablespoon at a time, until it reaches your desired flavor.
Now for the consistency check: the icing should be thick enough to hold its shape when drizzled but still flow smoothly. If it's too thick, whisk in small amounts of warm water (about 1 teaspoon at a time) until it reaches a velvety drip consistency. If it's too thin, add a bit more powdered sugar and whisk again. The ideal texture should allow the icing to cling to a spoon in a thick ribbon before dripping slowly back into the bowl.
Cool and Test for Perfect Dripping
Transfer the icing to a clean bowl and let it cool at room temperature for about 15 minutes. This resting period allows the flavors to meld and the texture to stabilize. Stir occasionally to prevent a skin from forming on the surface. The icing should thicken slightly as it cools, but it should still be pourable. If it becomes too thick, whisk in a few drops of warm water to restore the desired consistency.
For the final test, dip a spoon into the icing and lift it slowly. The icing should cling to the spoon in a thick, glossy sheet before dripping back into the bowl. This is the hallmark of a perfectly balanced chocolate icing—smooth, velvety, and just thick enough to create beautiful drips. If it's still too thick after cooling, a tiny splash of warm water will bring it back to perfection. Once you've achieved this consistency, your icing is ready to use.
Pro Tips For Making Hershey Dark Chocolate Icing
- CHOP CHOCOLATE SMALL: I learned this the hard way—using big chunks means uneven melting and grainy icing. Dice the Hershey’s bars into ¼-inch pieces so they melt evenly in the butter, no matter how impatient you are to get stirring.
- USE WARM BUTTER: Cold butter makes the icing seize up like glue. Melt the butter just until it softens (about 30 seconds in the microwave, or until it looks like wet sand), then mix it with the chocolate. This keeps the texture smooth without scrambling the sugar.
- SALT THE ICING: Diamond Crystal kosher salt isn’t just for flavor—it balances the sweetness and keeps the icing from tasting flat. Sprinkle a pinch (about ⅛ teaspoon) over the finished mixture while whisking; it dissolves fast and makes all the difference.
- WHISK UNTIL GLOSSY: Stop when the icing looks thick but still shiny—about 2-3 minutes of vigorous whisking. If you overwork it, you’ll end up with a dry, crumbly mess. Test by dragging a spoon through it; if it leaves a clean line, you’re golden.
Common mistakes when making perfect results
Overheating the Chocolate
This is the #1 reason chocolate icing seizes into a grainy mess. When you melt chocolate over direct heat or boiling water, it can exceed 118°F, triggering sugar crystallization. I've ruined batches by being impatient—always use a double boiler with simmering (not boiling) water.
Remove the bowl immediately after melting and let it cool to 100°F before adding powdered sugar. 🔥
Adding Powdered Sugar Too Fast
Dumping all 2 cups of powdered sugar at once creates lumps that whisking can't fix. Instead, sift it gradually while whisking constantly. I learned this the hard way—my first attempt looked like chocolate gravel.
For extra smoothness, use a fine-mesh sieve and whisk on medium-high speed for 3-4 minutes after adding all the sugar.
Skipping the Salt
That ¼ tsp salt might seem insignificant, but it's what makes the flavor sing. Without it, the icing tastes flat and one-dimensional. I used to omit it until I tasted a professional bakery's version—now I always include it. The salt enhances the chocolate's natural bitterness and balances sweetness perfectly.
Not Testing Consistency Early
Waiting until the end to check consistency leads to frustration. After whisking in the sugar, test immediately by dipping a spoon in the icing. It should cling in a thick ribbon before dripping back. If it's too thick, add warm water 1 teaspoon at a time.
Too thin? Add powdered sugar 1 tablespoon at a time. I keep a small bowl of warm water nearby for quick adjustments.
Using the Wrong Vanilla
Imitation vanilla extract ruins everything. It lacks the complex aromatic compounds that make real vanilla shine. Always use pure vanilla extract—I recommend McCormick Pure Vanilla or Bourbon-infused vanilla for extra depth. The difference is night and day. Even ½ teaspoon of quality vanilla elevates the flavor profile significantly.
Storing Improperly After Making
Letting icing sit at room temperature for too long causes it to thicken irreparably. Always transfer to an airtight container and refrigerate within 2 hours. When reheating, use 10-second bursts in the microwave with 15-second rests between.
Never microwave directly from the fridge—bring it to room temp first. The icing should be 70°F or warmer before reheating to prevent graininess.

Frequently asked questions
Can I substitute Hershey's dark chocolate with other brands?
Yes, but choose carefully! Brands like Ghirardelli 60% or higher or Lindt Excellence work best for that rich, velvety texture. Avoid milk chocolate—it won't have the same deep flavor or proper melt. If you must use chips, opt for callets (chocolate discs) instead of chopped bars for smoother melting.
How do I adjust the consistency for piping vs. drizzling?
For piping, thicken the icing slightly by adding 1 extra tablespoon of powdered sugar and whisking until smooth. For drizzling, thin it with ½ teaspoon warm water at a time until it flows like honey. Test by spooning—it should cling but still drip slowly.
Why did my icing turn grainy?
Overheating the chocolate (above 118°F) or adding powdered sugar too quickly are the top culprits. Always use a double boiler with simmering water (not boiling) and let the chocolate cool to 100°F before mixing. If it seizes, whisk in 1 teaspoon of warm water and 1 teaspoon of butter to restore smoothness.
Can I make this icing ahead of time?
Store it in an airtight container in the fridge for up to 1 week. For longer storage, freeze in 1-tablespoon portions. Thaw at room temperature for 10 minutes before use. Reheat gently in 10-second microwave bursts if it thickens—never microwave directly from the fridge.
What are the best desserts to use this icing on?
This icing shines on cakes, cupcakes, and cookies as a glaze, or drizzled over fruit tarts, cheesecakes, or ice cream. For extra flair, pipe swirls on brownies or use it as a filling for chocolate-dipped strawberries. The glossy finish works best on cooled desserts—never warm ones.
