Desserts
This Hershey dark chocolate icing recipe delivers a rich, ultra-thick drizzle that transforms ordinary cakes and cookies into showstopping desserts. I developed it after struggling with runny store-bought icings that never set properly—this version stays perfectly firm while maintaining that deep, fudgy chocolate flavor you crave.
The secret lies in precise ratios of chocolate, butter, and powdered sugar, combined with a simple melting technique that prevents graininess.
What sets this recipe apart is its versatility—use it as a glossy cake glaze, a thick cookie drizzle, or even a filling for brownies. The process is straightforward: melt the chocolate and butter together, then gradually whisk in powdered sugar until you reach that ideal spreadable-yet-stable consistency.
No special equipment needed beyond a double boiler or microwave, and the ingredients are simple enough to keep on hand for last-minute baking emergencies.
You'll end up with a silky-smooth chocolate icing that clings beautifully to frosting, drizzles elegantly over cookies, and stays firm at room temperature for hours. The flavor is pure Hershey's dark chocolate—intense, slightly bitter, and perfectly balanced.
This isn't just icing; it's the finishing touch that elevates any dessert from good to extraordinary.
For variations, try adding a splash of vanilla extract or a pinch of espresso powder to enhance depth, or swap in cream cheese for a tangy twist. The recipe scales easily, so double it for larger projects. Let's get started on creating that perfect chocolate finish.
Ingredients for hershey dark chocolate icing
Eight simple ingredients create a luxurious, ultra-thick chocolate finish perfect for cakes and cookies.
| Ingredient | Amount | Notes |
|---|---|---|
| Hershey's Special Dark Chocolate Bars 🍫 | 8 oz | High cocoa content preferred |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for even melting |
| Powdered Sugar 🍚 | 3 cups | Sifted for smooth texture |
| Heavy Whipping Cream 🥛 | ¼ cup | Full-fat for stability |
| Pure Vanilla Extract 🌿 | 1 tsp | Bottled for potency |
| Instant Espresso Powder ☕ | ½ tsp | Optional for depth |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | Fine grain for balance |
| Vegetable Shortening 🧊 | ¼ cup | For extra firmness |
The chocolate matters most here. Hershey's Special Dark delivers that signature fudgy depth, but any high-cocoa dark chocolate (70% or higher) works. Trader Joe's and Whole Foods carry excellent options—look for bars with vibrant, glossy exteriors and no white streaks. Butter should be cold and cubed; Plugrá or European-style brands yield superior results. Powdered sugar? Sift it first—clumps create graininess in the final icing. For the cream, full-fat heavy whipping cream prevents separation better than lighter versions.
No vanilla extract? Vanilla bean paste or even a scraped vanilla bean adds complexity. Short on espresso powder? Instant coffee granules work in a pinch, but reduce to 0.25 tsp for milder intensity. Substituting butter? Coconut oil melts cleanly but lacks richness—use at half the quantity. The shortening is optional but essential for ultra-thick applications like cake drip. For a tangy twist, swap 2 tbsp of the heavy cream for cream cheese, ensuring it's room temperature before mixing. All ingredients should be at room temperature except the butter, which needs to remain cold for proper emulsification.
This icing thickens as it cools, so refrigerate any leftovers for 30 minutes before reusing. Store in an airtight container for up to 2 weeks at room temperature or 3 months refrigerated. For large batches, portion into 1-ounce jars—perfect for decorating multiple desserts. Microwave the chocolate-butter mixture in 20-second bursts to avoid burning, stirring between each interval. The final consistency should be thick enough to hold peaks when drizzled but still pourable for intricate designs.

Step-by-step instructions for Hershey dark chocolate icing
Here's the precise method for creating a velvety, ultra-thick chocolate glaze that clings beautifully to cakes and cookies.
Melt the Chocolate and Butter Together
Begin by breaking the 8 oz Hershey's Special Dark Chocolate Bars into small, even pieces. Place them in a medium heatproof bowl set over a saucepan of simmering water, ensuring the bottom of the bowl doesn't touch the water. Add the 0.5 cup Unsalted Butter, cut into small cubes, to the chocolate. Stir occasionally as both melt together, which should take about 5 minutes.
The key here is patience—allowing the chocolate and butter to melt gradually prevents seizing or graininess. You'll know it's ready when the mixture becomes completely smooth and glossy, with no visible butter chunks. Remove the bowl from heat immediately after melting to avoid overheating, which can cause the chocolate to darken or develop an off flavor.
Whisk in Powdered Sugar and Shortening
Transfer the melted chocolate mixture to a large mixing bowl. Sift the 3 cups Powdered Sugar directly over the chocolate, then gently fold it in with a rubber spatula to avoid incorporating air. Add the 0.25 cup Vegetable Shortening and continue folding until fully incorporated. This step is crucial for achieving the ultra-thick consistency that makes this icing ideal for drizzling.
The vegetable shortening helps stabilize the icing, preventing it from becoming too runny when exposed to warm temperatures. If you notice any lumps, use a hand mixer on low speed for 10-15 seconds to smooth it out. The mixture should now resemble a thick, smooth paste with a glossy sheen.
Incorporate Flavorings and Cream
Add the 0.25 cup Heavy Whipping Cream, 1 tsp Pure Vanilla Extract, 0.5 tsp Instant Espresso Powder, and 0.25 tsp Diamond Crystal Kosher Salt to the chocolate mixture. Using a hand mixer, beat on medium speed for 2-3 minutes until completely smooth and fully combined. The espresso powder enhances the chocolate's depth, while the salt balances the sweetness.
This is where the icing transforms from a simple chocolate glaze to a complex, flavorful drizzle. The cream adds a luxurious texture, and the vanilla extract rounds out the bitterness of the dark chocolate. If the icing appears too thick at this stage, you can thin it slightly with 1-2 teaspoons of warm water, but it should remain thick enough to hold its shape when drizzled.
Cool and Adjust Consistency
Transfer the icing to a clean, airtight container and let it cool at room temperature for 30 minutes. This cooling period allows the icing to thicken further, making it easier to drizzle without running. If the icing is still too thin after cooling, refrigerate it for an additional 15-20 minutes to achieve the desired consistency.
The icing should be thick enough to hold its shape when drizzled but still flow smoothly. If it becomes too firm, you can soften it slightly by placing the container in warm water for 10-15 seconds. Once ready, use a piping bag fitted with a small round tip or a squeeze bottle to create elegant drizzles over cakes, cookies, or cupcakes. The finished icing should have a glossy, professional appearance with a rich, velvety texture.
Pro Tips For Making Hershey Dark Chocolate Icing
- Chop Chocolate Faster: Use a sharp knife and a cutting board—don’t rely on a dull blade or a food processor for this. Hershey’s dark bars melt unevenly if they’re not uniformly sized, and a knife gives you better control. (Yes, even if you’re impatient like me.)
- Melt Butter Slowly: Heat the butter gently over low heat until it’s just melted but not browned—this keeps the flavor clean. I learned this the hard way when I rushed it and ended up with a bitter, nutty taste that ruined the whole batch.
- Whip Cream Cold: Chill the heavy whipping cream in the fridge for at least 30 minutes before whipping—it stiffens better and won’t turn grainy. (Your future self will thank you when the icing isn’t lumpy.)
- Sift Powdered Sugar: Sift the powdered sugar directly into the warm chocolate-butter mixture to avoid clumps. I skip this sometimes, but the icing is noticeably smoother when I don’t. (Does it look weird? Yes. Does it work? Every single time.)
Troubleshooting perfect results
Grainy Chocolate Fix
If your icing develops a grainy texture, it’s usually from overheating or improper melting. To rescue it, immediately place the bowl over ice water for 30 seconds to cool rapidly, then whisk vigorously. The shock of cold temperature helps smooth out any crystallized chocolate particles.
For future batches, melt chocolate and butter together over low heat or in 20-second microwave bursts, stirring between each interval. 💡
Too Thin or Runny
If your icing is too thin after cooling, refrigerate it for 15-20 minutes to thicken naturally. For an immediate fix, whisk in 1-2 tablespoons of powdered sugar at a time until it reaches the desired consistency.
Avoid adding too much at once—this can make the icing stiff and difficult to drizzle. If the issue persists, reduce the heavy cream by 1 tablespoon in future batches.
Separation Issues
Separation occurs when the chocolate and butter aren’t fully emulsified with the powdered sugar. To fix it, place the bowl over a double boiler (or a heatproof bowl over simmering water) and gently warm while stirring constantly until smooth.
For prevention, always sift the powdered sugar and fold it gently into the melted chocolate mixture to avoid incorporating air. A splash of heavy cream (up to 1 tablespoon) can also help re-emulsify the icing if needed.
Icing Sets Too Fast
If your icing hardens quickly on the cake or cookies, it’s likely too thick or the room temperature is cool. To adjust, soften the icing by placing the container in warm (not hot) water for 10-15 seconds, then whisk until smooth.
For future batches, reduce the powdered sugar by ¼ cup or increase the heavy cream by 1 tablespoon to create a more workable consistency. Store unused icing in an airtight container at room temperature for up to 2 weeks to maintain its ideal texture.
Bubbles or Lumps
Air bubbles or lumps can ruin the silky finish of your icing. To eliminate them, transfer the icing to a piping bag fitted with a fine tip and gently press it through to force out air.
For stubborn lumps, use a hand mixer on low speed for 10-15 seconds to smooth it out. To prevent bubbles, avoid overmixing after adding the powdered sugar—fold it in gently with a spatula instead of whisking vigorously. 🌟
Flavor Imbalance
If the icing tastes too sweet or bitter, adjust the balance with vanilla extract (for sweetness) or espresso powder (for depth). For a sweeter batch, add 1-2 teaspoons of honey or maple syrup and whisk until fully incorporated.
To reduce bitterness, increase the vanilla extract to ½ teaspoon or add a pinch of sea salt. Always taste as you go—this icing is highly customizable, so don’t be afraid to tweak it to your preference!

Frequently asked questions
Can I substitute Hershey's dark chocolate with another brand?
Yes! Any high-quality dark chocolate with 70% cocoa or higher works perfectly. Brands like Ghirardelli, Lindt, or Whole Foods 365 are excellent alternatives. Just melt the same 8 oz amount—chocolate with higher cocoa content will taste more intense and slightly bitter. For a smoother texture, choose chocolate bars without additives or stabilizers.
How do I make this icing thinner for drizzling?
If your icing is too thick, gently warm it in 10-second microwave bursts while stirring, then thin it with 1 teaspoon of warm water at a time. For a smoother drizzle, reduce the powdered sugar by ¼ cup in future batches. Never use milk—it can cause separation. The ideal consistency should coat the back of a spoon but still flow freely when drizzled.
Why did my icing turn grainy?
Graininess usually happens from overheating or improper melting. To fix it, place the bowl over ice water for 30 seconds, then whisk vigorously. For next time, melt chocolate and butter together over low heat or in 20-second microwave bursts, stirring between each interval. Avoid direct heat—it causes sugar crystals to form and create that gritty texture.
Can I use this icing for cupcakes instead of cakes?
This icing works beautifully for cupcakes—just let it cool completely before piping to prevent melting. For a swirl effect, pipe a rosette on top, then drag a toothpick through the center. The ultra-thick consistency makes it perfect for holding its shape on cupcakes, even in warm rooms. Store leftover icing in an airtight container for up to 2 weeks.
What's the best way to store leftover icing?
Transfer any unused icing to an airtight container and store it at room temperature for up to 2 weeks. For longer storage, refrigerate it for up to 3 months. To reuse, let it sit at room temperature for 10-15 minutes or warm it gently in 10-second microwave bursts while stirring until smooth. Avoid freezing—it can alter the texture.
