Ingredients You’ll Need

It’s amazing how just a few basic ingredients come together to create this beautiful, decadent cake. The boxed chocolate cake is your time-saver, while the homemade frosting and ganache bring in that homemade flair. I recommend picking up good-quality chocolate chips—they make a noticeable difference.

• Chocolate cake mix: Choose your favorite brand—I’ve found that a moist, fudgy mix works best.
• Unsalted butter: Make sure it’s softened to room temperature for easy mixing and a fluffy frosting.
• Confectioners’ sugar: This keeps the frosting smooth and sweet without any grit.
• Marshmallow crème: Adds the perfect light, creamy texture and a subtle marshmallow flavor to the frosting.
• Vanilla extract: Just a teaspoon enhances all the other flavors beautifully.
• Kosher salt: A pinch balances sweetness and deepens flavor complexity.
• Heavy cream: Essential for a silky ganache that’s simple to pour over the cake.
• Semisweet chocolate chips: These melt perfectly for the ganache—don’t sub with baking chocolate unless you adjust sweetness.
• Store-bought vanilla icing: This is for decorating the spiderweb; it’s thick enough to hold its shape when piped.

Variations

I love tweaking this Spiderweb Cake Recipe to suit different occasions and tastes. Don’t be shy to experiment—you might find a new favorite twist!

• Flavor Swap: I’ve made this with red velvet cake mix instead of chocolate for a festive twist—plus, the white spiderweb pops beautifully on that red background.
• Dairy-Free Version: Replace butter with coconut oil and use dairy-free chocolate chips and cream alternatives—I tried this for a friend and it turned out amazing.
• Extra Crunch: My family loves to add crushed cookies or toasted nuts between the layers for some texture contrast.
• Chocolate Ganache Variations: Sometimes I stir in a splash of espresso to the ganache for a mocha note that elevates the flavor dramatically.

How to Make Spiderweb Cake Recipe

Step 1: Prepare the Cake Pans and Batter

Begin by buttering and lightly flouring two 9” round cake pans. I like to do this step carefully to ensure the cakes pop out cleanly after baking. Then, prepare the cake batter according to the package instructions. You can’t go wrong sticking to the directions here—it guarantees a perfect cake base.

Step 2: Bake and Cool the Cakes

Bake as directed on the box. Once your cakes are out of the oven, let them cool completely in their pans for about 10 minutes, then transfer to a wire rack. This helps avoid soggy bottoms and ensures the ganache won’t melt or slide off later.

Step 3: Make the Marshmallow Frosting

In a large bowl, beat together the softened butter, confectioners’ sugar, marshmallow crème, vanilla extract, and a pinch of kosher salt using a hand mixer. Mix until the frosting is light, fluffy, and fully combined. This frosting has that sweet, cloud-like texture I adore and pairs beautifully with the rich cake.

Step 4: Assemble the Cake Layers

Place the first cake layer on your serving platter, spread a thin layer of frosting if desired (I sometimes do for extra moisture), then place the second cake layer on top. You’ll build your ganache right on top of this stack.

Step 5: Prepare the Chocolate Ganache

Heat the heavy cream in a small saucepan until it just begins to bubble around the edges—don’t let it boil. Pour it over the semisweet chocolate chips in a heatproof bowl and let it sit for two minutes. Then whisk until silky smooth. This ganache thins enough to pour but thickens into a shiny, luscious glaze over the cake. It’s magical.

Step 6: Decorate With the Spiderweb

Pour the ganache evenly over the top of the cake, letting it drip slightly down the sides. Then, using your store-bought vanilla icing in a tube, pipe a spiral starting from the center outwards. The trick I discovered is to drag a toothpick gently from the center outward through the spiral lines, creating a perfect spiderweb effect. It looks intricate but is actually super easy once you get the hang of it!

How to Serve Spiderweb Cake Recipe

Garnishes

For a little extra flair, I sometimes sprinkle edible silver glitter over the spiderweb or tuck in tiny plastic spiders (for fun, of course) around the edges. Fresh berries on the side add a nice contrast too, especially raspberries or red currants to echo the spooky vibe with a pop of color.

Side Dishes

I love pairing this cake with a scoop of vanilla bean ice cream or a dollop of lightly sweetened whipped cream. For drinks, a cup of strong coffee or a bold black tea complements the chocolate perfectly.

Creative Ways to Present

Once, for a Halloween party, I placed the cake on a platter lined with a bed of crushed Oreo “dirt,” with plastic spider rings nestled in. It’s simple and makes the entire display pop. I’ve also used colored icing to pipe little spiders heading toward the web for a playful effect.

Make Ahead and Storage

Storing Leftovers

I store leftover Spiderweb Cake wrapped tightly with plastic wrap in the fridge. Because of the ganache and marshmallow frosting, it stays moist for up to 4 days. Just bring it to room temperature before serving so the flavors and textures shine.

Freezing

If you want to freeze it, I recommend freezing the cake layers separately and assembling the cake fresh. However, if you freeze the whole cake, wrap it well with foil and plastic wrap to avoid freezer burn; it can keep for up to 2 months. Thaw slowly in the fridge overnight.

Reheating

For best results when reheating small slices, I let them come to room temperature and then warm for 10 seconds in the microwave just to take the chill off. Too long and the ganache can get melty but cold slices are also delicious!
