There’s a special kind of magic that October brings, and for me, it always culminates in the joyous celebration of Halloween. Growing up, I was completely captivated by everything spooky and fun: the thrill of scary movies, the creativity of decorating every corner of the house, and, of course, the unparalleled delight of all the Halloween candy. But now, as a parent, my love for this festive holiday has truly blossomed, deepening in ways I never imagined.
My children are at that enchanting age where Halloween is pure, unadulterated excitement. They fully grasp the magic of it all – from meticulously planning their costumes for weeks on end to the anticipation of trick-or-treating. In fact, my daughter began discussing her Halloween costume ideas immediately after last year’s festivities, her mind a whirlwind of possibilities that must have shifted at least ten times since! The collective buzz in our home is palpable; on October 1st, they all woke up with joyful cheers, celebrating the official arrival of their favorite month and the imminent approach of Halloween. Witnessing their enthusiasm and wonder truly reinvigorates my own holiday spirit.
While my days of dressing up might be less frequent now (though perhaps this year is the time for a comeback!), and I’ve admittedly become a bit of a “wimp” when it comes to scary movies, my affection for Halloween remains as strong as ever. I believe it’s largely because I get to experience the holiday anew through the innocent, sparkling eyes of my kids. Their excitement is contagious, and it reminds me of the simple joys of childhood. Moreover, Halloween provides the perfect excuse to get creative in the kitchen, concocting an array of fun, themed treats that bring smiles to everyone’s faces. And this year, the spotlight shines brightly on these truly magnificent Ultimate Chocolate Cupcakes.

This year, for all our Halloween celebrations, these Ultimate Chocolate Cupcakes are absolutely stealing the show. And when I say “ultimate,” I truly mean it. These are not merely chocolate cupcakes; they are a multi-layered symphony of chocolate, designed for the most ardent chocolate connoisseur. Imagine a perfectly moist, deeply flavorful chocolate cupcake as the foundation, expertly cored and filled with a decadent, airy chocolate mousse. This luscious core is then generously piped with a rich, smooth chocolate buttercream, culminating in a delicate drizzle of vibrant white chocolate ganache. As if that weren’t enough, I even adorned them with chocolate candies, ensuring every single bite delivers an intense, satisfying chocolate rush.
The journey to creating these ultimate treats began with a time-honored, incredibly reliable base recipe. For the chocolate cupcakes themselves, I turned to the famously dependable HERSHEY’S PERFECTLY CHOCOLATE Chocolate Cake Recipe. This recipe is a true marvel of versatility and consistent deliciousness. I had the privilege of seeing its adaptability firsthand during a visit with HERSHEY in Pennsylvania, where we witnessed it transform effortlessly into various forms – from a towering three-layer cake to a charming two-layer cake, a classic bundt cake, and, of course, perfect cupcakes. Knowing I needed a truly exceptional cupcake foundation, there was no doubt this was the recipe to use. While I typically need to make some high-altitude adjustments for baking in my location, especially for cupcakes, I’ve meticulously included those specific modifications right below the main recipe to ensure everyone can achieve the same flawless results, regardless of their elevation.

While the rich, multi-layered chocolate flavor is undeniably the star of these ultimate cupcakes, their festive Halloween appeal truly comes alive through the decorations. I may not consider myself a master cake decorator with elaborate techniques, but I absolutely adore the process of making cupcakes look as fun and appealing as they taste. I knew with a bit of creativity, I could transform these into delightful Halloween treats that would enchant both kids and adults.
My initial thought was to use a simple chocolate ganache for the topping, but then inspiration struck! By switching to a white chocolate ganache, I gained the ability to tint it with vibrant colors, perfectly aligning with the playful spirit of Halloween. This allowed for endless possibilities in creating visually stunning and thematic designs. For our spooky celebration, a bright, ghoulish green seemed like the perfect choice.
Creating perfectly colored ganache requires a little finesse, and I have a couple of essential tips to share that will ensure your success. First, working with white baking chips is slightly different from their semi-sweet counterparts. White chips tend to be more sensitive to heat and can seize up or become grainy if not melted properly. The absolute best method to achieve a silky-smooth, pourable white chocolate ganache is to use a double boiler. Gently combine the white chips with the heavy cream in the top of a double boiler set over simmering water. Stir continuously and patiently until the mixture is completely smooth and free of any lumps. Avoid high heat or rushing the process, as this is where white chocolate can become problematic.
My second crucial tip pertains to coloring your ganache: always, and I mean *always*, use a paste or gel food coloring. Liquid food colorings, while common for other applications, introduce too much water into the white chocolate mixture, almost guaranteeing that your ganache will seize up and become an unusable, clumpy mess. Paste or gel colorings are highly concentrated and won’t interfere with the delicate emulsion of the white chocolate and cream. You have complete freedom to choose any color that speaks to your Halloween theme – my husband suggested a classic orange, but a vivid green was firmly stuck in my head, and I absolutely loved the whimsical, slightly spooky outcome! Once your vibrant ganache is ready, the fun continues with the toppings. You can crown your cupcakes with an assortment of holiday nonpareils, festive sprinkles, or any small candies. I used some charming candy balls from my grocery store’s bulk section, but imagine how fantastic REESE’S PIECES would look and taste here, adding both color and a delicious peanut butter crunch!
These Ultimate Chocolate Cupcakes, with their rich chocolate layers and playful Halloween decorations, are destined to be the star attraction at all your Halloween parties and gatherings this year. They are a delightful combination of gourmet flavor and festive fun, sure to impress every guest.

Ingredients
Cupcakes:
- 2 cups granulated sugar
- 1 3/4 cups all-purpose flour
- 3/4 cup HERSHEY’S Cocoa
- 1 1/2 teaspoons baking powder
- 1 1/2 teaspoons baking soda
- 1 teaspoon salt
- 2 large eggs
- 1 cup milk
- 1/2 cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup boiling water
Chocolate Mousse Filling:
- 3/4 cup heavy whipping cream
- 1 1/2 tablespoons confectioners’ sugar
- 1/2 teaspoon vanilla extract
- 3 tablespoons HERSHEY’S Simply 5 Chocolate Syrup
- 1 1/2 tablespoons HERSHEY’S Cocoa
Chocolate Frosting:
- 3 oz HERSHEY’S Unsweetened Baking Bar
- 4 1/2 cups confectioners’ sugar
- 2 tablespoons HERSHEY’S Cocoa
- 1 1/2 cups Unsalted Butter at room temperature
- 2 tablespoons heavy whipping cream
- 1 teaspoon vanilla extract
Green Ganache:
- 6 oz HERSHEY’S Premier White Chips
- 1/4 cup heavy whipping cream
- green paste food coloring
- holiday nonpareils or candy
Instructions
to bake the cupcakes:
- Preheat your oven to 350ºF (175ºC). Prepare three 12-cup muffin tins by lining each cup (2-1/2 inches in diameter) with paper baking cups. This recipe yields a generous 36 cupcakes, perfect for sharing.
- In a large mixing bowl, combine the dry ingredients: granulated sugar, all-purpose flour, HERSHEY’S Cocoa, baking powder, baking soda, and salt. Whisk them together thoroughly until well combined. Next, add the wet ingredients: eggs, milk, vegetable oil, and vanilla extract. Using an electric mixer, beat the mixture on medium speed for precisely 2 minutes, ensuring everything is fully incorporated and smooth. Carefully, and slowly, stir in the boiling water until the batter is uniform. Fill each prepared baking cup approximately 1/2 full with the cupcake batter; avoid overfilling to prevent spillage and ensure even baking.
- Bake the cupcakes for 22 to 25 minutes. To check for doneness, insert a wooden skewer or toothpick into the center of a cupcake; if it comes out clean, they are ready. Once baked, remove the muffin tins from the oven and allow the cupcakes to cool completely on a wire rack before proceeding with the filling and decorating.
to make the chocolate mousse:
- For the best results with your chocolate mousse, ensure both your mixing bowl and beaters are thoroughly chilled. In the chilled bowl, beat the heavy whipping cream on medium-high speed until soft peaks begin to form. Gradually add the confectioners’ sugar and vanilla extract, continuing to beat until stiff peaks are achieved. Finally, gently fold in the HERSHEY’S Simply 5 Chocolate Syrup and HERSHEY’S Cocoa powder until just combined. Be careful not to overmix. Refrigerate the chocolate mousse until you are ready to fill the cupcakes, allowing it to firm up slightly.
to make the chocolate frosting:
- Begin by melting the HERSHEY’S Unsweetened Baking Bar. The ideal method is to use a double boiler, or carefully melt it in a microwave in short intervals, stirring frequently, until smooth. Once melted, set the chocolate aside and allow it to cool slightly until it’s just warm to the touch, not hot.
- In a separate medium-sized bowl, whisk together the confectioners’ sugar and HERSHEY’S Cocoa powder to ensure there are no lumps. Add the room temperature unsalted butter to this mixture and beat with an electric mixer until it is smooth and creamy. Gradually incorporate the slightly cooled melted chocolate, continuing to beat until fully combined. Finally, add the heavy whipping cream and vanilla extract. Beat the frosting for an additional 2-3 minutes on medium-high speed, until it becomes wonderfully light, fluffy, and perfectly pipeable.
to make the ganache:
- To create the vibrant ganache, combine the HERSHEY’S Premier White Chips and the heavy whipping cream in a double boiler. Place the double boiler over low heat, ensuring the water in the bottom pot is simmering gently and not boiling. Stir the mixture frequently until the white baking chips are completely melted and the ganache becomes perfectly smooth and luscious. Remove from heat and, while still warm, carefully stir in your chosen green paste food coloring until the desired hue is achieved. Keep the ganache warm for easier drizzling.
to assemble the cupcakes:
- Once the cupcakes are completely cooled, it’s time to add the delicious mousse filling. Using a sharp paring knife or a cupcake corer, carefully cut a cone shape from the center of each cupcake, about ¾” in diameter and ¾” deep. Slice off the pointed end of the removed cone portion and set aside the remaining top piece. Fill each hollowed-out cupcake with approximately 1 teaspoon of the chilled chocolate mousse. Gently place the reserved cupcake tops back over the mousse filling, creating a neat cap.
- Transfer the prepared chocolate frosting into a piping bag fitted with your favorite decorative tip (a large star tip works beautifully for a classic look). Pipe the frosting onto the filled cupcakes, creating an elegant swirl or a generous mound.
- While the colored ganache is still warm and pourable, use a spoon to delicately drizzle a generous amount over the top of each frosted cupcake. Allow the ganache to cascade down the sides of the frosting, creating an enticing drip effect. Immediately, before the ganache completely sets, add your holiday nonpareils, festive sprinkles, or chosen candies to the top of the cupcakes. This ensures they adhere beautifully and add that perfect touch of Halloween charm.
Recipe Notes:
* Reduce granulated sugar by 2 tablespoons.
* Decrease baking powder by 1/4 teaspoon.
* Decrease baking soda by 1/4 teaspoon.
* Increase milk by 2 tablespoons.
These adjustments help maintain the ideal moisture and texture when baking at higher elevations.
