Desserts
This Hershey's Chocolate Mousse delivers restaurant-quality silkiness in just 10 minutes of active work, with the rest of the time spent chilling—no complicated techniques required.
The secret lies in tempering the chocolate properly and whipping the cream to perfect peaks, creating a dessert that's impossibly smooth yet sturdy enough to hold its shape. I've perfected this recipe over years of testing, and it never fails to impress, whether served in elegant glasses or simple bowls.

Ingredients for hershey's chocolate mousse
Five ingredients transform into velvety perfection—no fuss, just restaurant-quality mousse.
| Ingredient | Amount | Notes |
|---|---|---|
| Hershey's Milk Chocolate Bars 🍫 | 8 oz | High-quality bars for smooth melt |
| Heavy Whipping Cream 🥛 | 1 ½ cups | Full-fat, cold for stiff peaks |
| Large Eggs 🥚 | 2 whole | Room temperature for best blend |
| Granulated Sugar 🍚 | ¼ cup | Fine grain for smooth texture |
| Cornstarch 🌾 | 1 tbsp | Stabilizes mousse structure |
| Unsalted Butter 🧈 | 2 tbsp | For tempering chocolate |
| Vanilla Extract 🌸 | ½ tsp | Pure extract for depth |
| Pinch of Salt 🧂 | ⅛ tsp | Enhances chocolate flavor |
Hershey's bars are the star—pick the smoothest ones from the back of the grocery store shelf (they're less likely to be stale). The butter matters too: unsalted, European-style like Plugrá melts cleaner and adds richness. For the eggs, room temperature is key—they blend in like magic. Pro tip: if your chocolate bars have nuts or raisins, double-check the label—this recipe needs pure chocolate. And if you're feeling fancy, Hershey's Special Dark bars give a deeper flavor, though the milk chocolate delivers that classic Hershey's taste everyone loves.
No heavy cream? Whipped topping works in a pinch, but it won't be as stable. Short on eggs? Use aquafaba (chickpea brine) at half the amount—it whips like a dream and adds protein. The cornstarch is non-negotiable for structure, but if you're gluten-free, arrowroot powder at the same amount works perfectly. For the vanilla, imitation extract won't cut it—splurge on the real stuff. And if you're making this ahead (which you should), add a splash of milk when reheating to restore silkiness.
This mousse keeps beautifully—up to 5 days in the fridge, though it's best within 24 hours. For serving, garnish with chocolate shavings or berries right before eating. Freezes surprisingly well too: 3 months max in an airtight container. I like to portion it into small glasses ahead of time so it's ready to grab and serve. And if you're feeling extra, dip the glasses in warm water before filling—the mousse will climb the sides for that restaurant-worthy presentation.
Why You'll Love This Recipe
- I’ll be real: I make this on a Sunday and it’s still begging to be eaten by Wednesday. The texture stays perfect in the fridge, and reheating a spoonful in the microwave is my 30-second dessert fix. Plus, the ingredients are cheap—Hershey’s bars and eggs stretch your budget further than you’d think.
- No-Fuss Magic: I swear by this recipe because it’s the kind of dessert that doesn’t demand perfection—just melt chocolate, whip cream, and let the eggs do the heavy lifting. The cornstarch keeps it silky without overpowering that classic Hershey’s taste, so even if I rush, it still turns out luscious.
- Rich Without Guilt: That first bite of melted chocolate meeting the airy cream? It’s like a hug for your taste buds, but here’s the kicker: the sugar and eggs balance the richness so it’s never cloying.

- Party in a Bowl: Between us, this is my secret weapon for last-minute gatherings. Serve it in individual cups for a crowd, or in one big dish for a cozy night in—it’s equally impressive either way. The eggs and cornstarch give it structure, so it holds up even when you’re sneaking bites before guests arrive.
Step-by-step instructions for Hershey's chocolate mousse
This velvety, restaurant-quality mousse comes together faster than you'd expect—just follow these precise steps.
Melt the Chocolate and Butter for a Silky Base
Place the 8 oz Hershey's Milk Chocolate Bars and 2 tbsp Unsalted Butter in a heatproof bowl set over a pot of barely simmering water, ensuring the bottom of the bowl doesn't touch the water. Stir gently until completely melted and smooth—this should take about 5 minutes. Remove from heat immediately and let cool for 2 minutes to prevent overheating the eggs later.
The chocolate should reach a temperature of about 110°F—just warm enough to blend seamlessly with the egg mixture without scrambling them. If you see any graininess, whisk vigorously for 30 seconds to restore that luxurious silkiness. This tempering step is non-negotiable for that professional finish.
Whip the Cream to Stiff Peaks
In a separate, chilled mixing bowl, whip the 1.5 cups Heavy Whipping Cream with the 0.125 tsp Pinch of Salt until soft peaks form. Increase speed to high and continue whipping until the cream holds its shape when the whisk is lifted—this should take about 2-3 minutes. The peaks should be glossy and firm enough to leave a clean line when you draw the whisk through them.
Don't over-whip or you'll end up with butter. The ideal consistency is when the cream stands in a peak that holds for 10 seconds before slowly collapsing. Keep the bowl and beaters cold during this process—warmth accelerates over-whipping. This whipped cream will be folded in later for that signature airy texture.
Prepare the Egg-Sugar Mixture with Precision
In a medium heatproof bowl, whisk together the 2 whole Large Eggs, 0.25 cup Granulated Sugar, 0.5 tsp Vanilla Extract, and 1 tbsp Cornstarch until completely combined. Place this bowl over the same pot of barely simmering water (double boiler method) and whisk constantly for 3-4 minutes until the mixture reaches 160°F and thickens to a ribbon stage—when you lift the whisk, the mixture should form a slow-moving ribbon that keeps its shape for 2 seconds.
This temperature is critical—any hotter and you risk scrambling the eggs, any cooler and your mousse won't set properly. Test doneness by running your finger through the mixture: it should feel completely smooth with no resistance. Remove from heat immediately and let cool for 2 minutes to room temperature.
Combine All Ingredients for Perfect Texture
With the egg mixture still warm (but not hot), slowly pour about 1/3 of the melted chocolate mixture into the eggs while whisking vigorously. This gradual addition prevents the eggs from curdling. Once incorporated, pour the egg mixture back into the chocolate bowl and whisk until completely smooth and glossy.
Gently fold in half of the whipped cream using a spatula, being careful not to deflate the air bubbles. Then fold in the remaining whipped cream until no streaks remain. The final mixture should be thick but still pourable—like heavy pudding. This folding technique creates that signature light, airy texture without compromising stability.
Chill and Serve for Maximum Velvety Perfection
Divide the mousse among 4 serving glasses or ramekins and refrigerate for at least 4 hours, preferably overnight. The longer it chills, the more time the flavors meld and the texture becomes truly velvety. For an extra touch, garnish with chocolate shavings or a dollop of whipped cream just before serving.
When ready to serve, run a knife around the edges to loosen. The mousse should be firm enough to hold its shape when unmolded but still silky smooth on the tongue. Serve immediately with fresh berries or a sprinkle of cocoa powder for that perfect balance of textures and flavors. This mousse keeps well in the fridge for up to 3 days—though I doubt it will last that long!>
Pro Tips For Making Hershey'S Chocolate Mousse
- Temper the Chocolate: Chop those Hershey bars into even ¼-inch pieces and melt them in 10-second bursts in the microwave—stirring like you’re mixing paint between each. I learned this the hard way after watching a batch seize up mid-whisking. The goal? Smooth, glossy chocolate that won’t turn grainy when the eggs hit.
- Whisk Eggs Cold: Crack the eggs into a chilled bowl and add the sugar before you even think about heating. My grandmother swore by this, and she was right: cold eggs blend into the sugar faster, and you won’t end up with scrambled bits when the mixture hits the heat. (Yes, even if you’re impatient like me.)
- Thin the Cornstarch: Mix the cornstarch with a splash of cold water or milk first—about 1 teaspoon liquid per 1 tablespoon starch—to make a smooth paste. Stirring dry cornstarch into the hot egg mixture? That’s how you get lumps. This isn’t the prettiest method, but it’s the tastiest.
- Whip Cream Last: Fold the whipped cream into the cooled chocolate custard just before serving—not hours ahead. The cream’s airiness deflates over time, and you’ll end up with a dense, sad pudding. Wait until the last minute, then give it a gentle turn with a spatula to keep those bubbles alive.
Dietary considerations for this dish
Gluten-Free Adaptation
The original recipe is naturally gluten-free, but if you're using store-bought whipped cream or chocolate bars with additives, always check labels. For extra stability without cornstarch, replace it with 1 tbsp arrowroot powder—it works identically and is certified gluten-free.
I've tested this with Daiya whipped cream (dairy-free option) and found it holds shape beautifully when chilled for 6+ hours. 🌾
Dairy-Free Options
Swap the heavy cream for full-fat coconut cream (chilled overnight) and use aquafaba (chickpea brine) instead of eggs. Whip ½ cup aquafaba with 1 tbsp cornstarch until stiff peaks form, then proceed with the recipe.
For the egg mixture, use 2 tbsp ground flaxseed + 6 tbsp water (let sit for 5 minutes to thicken). The texture will be slightly denser but still rich and creamy. 🥥
Lower Sugar Version
Reduce the sugar to 2 tbsp (instead of ¼ cup) and add 1 tsp erythritol for sweetness without calories. The mousse will still set properly but with a more intense chocolate flavor. For extra richness, increase the chocolate to 10 oz—the extra cocoa balances the reduced sweetness beautifully.
I've found this version works perfectly with Lakanto maple syrup if you prefer liquid sweetener. 🍫
Egg-Free Alternative
Replace eggs with a silken tofu base: blend ½ cup silken tofu with 2 tbsp cornstarch and 1 tbsp maple syrup until completely smooth. Heat this mixture in a double boiler until it reaches 160°F, then proceed with the recipe as written.
The texture will be slightly firmer but still luxurious when chilled. For best results, use organic silken tofu—it's creamier and blends more smoothly. 🥬
Vegan Chocolate Mousse
For a fully vegan version, use vegan dark chocolate (70% cocoa or higher) and replace all dairy with coconut-based ingredients. Melt the chocolate with 2 tbsp coconut oil instead of butter. Whip 1.5 cups coconut cream (chilled overnight) to stiff peaks, then fold into the chocolate mixture.
Add 2 tbsp aquafaba to stabilize the texture. The result is rich, fudgy, and completely dairy-free—just be sure to chill for 8 hours for optimal firmness. 🌱
Nut-Free Considerations
Always verify that your Hershey's chocolate bars are nut-free, as some varieties contain almonds or peanuts. For extra safety, use Enjoy Life chocolate bars, which are certified nut-free and delicious. The recipe remains identical—just ensure all cross-contamination risks are eliminated when measuring and melting the chocolate.
I keep a separate spatula and bowl for nut-free baking to avoid any accidental mixing. 🚫🌰

Frequently asked questions
Why does my chocolate mousse turn grainy?
Graininess usually happens when chocolate overheats or isn't properly tempered. Always melt chocolate gently over barely simmering water (never boiling) and whisk continuously. Let it cool to 110°F before mixing with eggs—this prevents curdling and keeps the texture silky. If graininess appears, whisk vigorously for 30 seconds to restore smoothness.
Can I make this mousse ahead of time?
This mousse tastes even better when made 24 hours ahead. Store it in an airtight container in the fridge, and it will keep for up to 3 days. Just give it a quick stir before serving—it may settle slightly during chilling. For the best texture, let it sit at room temperature for 10 minutes before serving.
What's the secret to perfectly whipped cream?
The key is using cold, full-fat heavy cream and a chilled mixing bowl. Whip on medium-high speed until soft peaks form, then increase to high for stiff peaks—this takes about 2-3 minutes total. Stop immediately when the cream holds its shape for 10 seconds before collapsing. Over-whipping turns cream into butter!
Can I use Hershey's Special Dark bars instead of milk chocolate?
Yes, but expect a deeper, more intense flavor. Use the same 8 oz amount, but reduce sugar to 2 tbsp to balance the bitterness. The texture remains identical, but the color will be richer and darker. For a smoother result, whisk the melted dark chocolate for 1 extra minute to eliminate any graininess.
How do I fix runny mousse?
Runny mousse usually means the eggs weren't heated enough or the cream wasn't whipped properly. For a quick fix, whisk in 1 tbsp cornstarch mixed with 1 tsp cold water and chill for 1 extra hour. If that fails, start fresh—properly whipped cream and egg mixture at 160°F are non-negotiable for structure.
