Key Ingredients for a Spider Web Cake
A spider web cake might look like a masterpiece, but the ingredients are super approachable — many of them already live in your pantry. What sets this Halloween cake apart is its bold look and layered flavor.
For the Black Cocoa Cake Layers
To get that deep, dramatic color, you’ll need black cocoa powder. It’s richer and smoother than regular cocoa and gives the cake an intense dark chocolate flavor without using food coloring. Pair it with all-purpose flour, granulated sugar, baking soda, and a splash of vanilla extract for balance. Add buttermilk and hot coffee (or water) to make the cake extra moist.
For the Orange Buttercream Frosting
This is where the Halloween vibe really pops. Use unsalted butter, powdered sugar, a touch of heavy cream, and a drop of orange extract to brighten the flavor. A gel-based orange food color brings it all together without watering down the mix.
For the Spider Web Design
To pipe the web, you’ll need a separate batch of white buttercream or royal icing. Shortening helps the white stay crisp and vibrant, especially when using a fine tip like #2 for detailed webbing.
How to Make a Spider Web Cake – Step by Step
Let’s get into the nitty-gritty of baking your spider web cake. Don’t worry — it’s easier than it looks. With a bit of patience and the right steps, you’ll end up with a spooky showpiece that tastes just as good as it looks.
Bake the Black Cocoa Cake Layers
- Preheat your oven to 350°F (175°C). Grease and line three 6-inch or two 8-inch round pans.
- In one bowl, whisk together flour, black cocoa powder, baking soda, baking powder, salt, and sugar.
- In another bowl, combine buttermilk, eggs, oil, vanilla, and hot coffee (or water).
- Mix wet into dry until you get a thin, smooth batter.
- Pour evenly into pans and bake for 30–35 minutes. Cool completely before frosting.
Make the Orange Buttercream
Whip butter until fluffy, then add powdered sugar, orange extract, and a little cream. Add orange gel color and beat until smooth.
Assemble the Cake
Stack and fill with frosting, then crumb coat and chill. Add a final smooth layer of orange buttercream.
Pipe the Web
Using a fine tip, draw your spider web with white icing — and voilà, your eerie masterpiece is done!

FAQs About Spider Web Cake
Got questions about your spider web cake? You’re not alone! Whether you’re baking for the first time or planning a Halloween party masterpiece, here are the answers to the most common questions people ask.
How do you make a spider web cake topper?
You can create a simple topper using melted white chocolate or candy melts. Pipe the web shape onto parchment paper, let it cool, and carefully peel it off. Place it gently on top of the cake for a striking 3D effect. Want something reusable? Use a lightweight plastic topper from craft stores.
What icing is best for spider web piping?
Royal icing is your best friend if you’re aiming for sharp, clean lines that dry quickly. It’s great for precision and won’t melt if the cake gets warm. That said, white buttercream works too — just chill the cake first so the lines stay crisp.
Can I make the spider web cake without food coloring?
Yes, but the vibe will change slightly. Use black cocoa powder to achieve a naturally dark cake layer. For the frosting, leave it white or lightly tint with natural alternatives like beetroot powder or activated charcoal. It won’t be bright orange, but still totally spooky!
How far in advance can I make a spider web cake?
You can bake the cake layers up to 3 days ahead, wrapped tightly in plastic and stored in the fridge. Frost and decorate the day before serving for the freshest look. If you’re using royal icing for the web, allow extra time for it to dry completely.
