Why You’ll Love This Recipe
I love how this cake combines a deep, rich chocolate flavor with a festive twist.

It’s perfect for parties, and I can easily make it ahead of time. Plus, the texture is soft, moist, and satisfies every chocolate craving.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
- All-purpose flour
 - Unsweetened cocoa powder
 - Baking soda
 - Baking powder
 - Salt
 - Granulated sugar
 - Brown sugar
 - Eggs
 - Buttermilk
 - Vegetable oil
 - Vanilla extract
 - Hot water or freshly brewed coffee
 - Semi-sweet or dark chocolate (for ganache)
 - Heavy cream
 - White chocolate or white candy melts (for the spiderweb)
 
Directions
- I start by preheating my oven to 350°F (175°C) and greasing two 8-inch round cake pans.
 - In a large bowl, I whisk together the dry ingredients: flour, cocoa powder, baking soda, baking powder, and salt.
 - In another bowl, I beat the eggs, then add both sugars, buttermilk, oil, and vanilla. I mix until well combined.
 - I gradually add the dry mixture to the wet ingredients, stirring gently. I pour in the hot water (or coffee) and mix until smooth.
 - I divide the batter evenly between the pans and bake for about 30–35 minutes, or until a toothpick comes out clean.
 - Once baked, I let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
 - For the ganache, I heat the heavy cream until steaming and pour it over the chopped chocolate. I let it sit for a minute, then stir until glossy and smooth.
 - I pour the ganache over the top of the stacked and leveled cakes, letting it drip slightly over the sides.
 - To make the spiderweb, I melt the white chocolate and pipe it in concentric circles over the ganache. Using a toothpick, I drag lines from the center outwards to create the web effect.
 - I let the ganache set before slicing and serving.

Variations
- I sometimes add a touch of espresso powder to the batter to enhance the chocolate flavor even more.
 - For a more intense filling, I spread raspberry jam between the cake layers before adding ganache.

storage/reheating
I store leftover cake in an airtight container at room temperature for up to 2 days or refrigerate it for up to 5 days. If chilled, I let it sit at room temperature for 20–30 minutes before serving to bring back the soft texture. I avoid microwaving it to maintain the ganache and web design.
FAQs
How do I create the perfect spiderweb design?
I make sure the ganache is slightly set but still glossy before piping the white chocolate. Then I draw concentric circles and drag a toothpick outward to get that signature web look.
Can I make this cake ahead of time?
Yes, I often bake the cake layers a day in advance and wrap them tightly in plastic. I decorate it the next day to keep it fresh and make party prep easier.
What can I use instead of white chocolate for the web?
I’ve used white candy melts or even icing gel in a piping bag. Anything that sets firmly on chocolate ganache works.
Can I freeze this cake?
Yes, I freeze the undecorated cake layers wrapped tightly for up to 2 months. I thaw them overnight in the fridge before assembling and decorating.
What if I don’t have buttermilk?
I make my own by adding 1 tablespoon of vinegar or lemon juice to 1 cup of milk. I let it sit for 5–10 minutes before using.
Conclusion
This Spiderweb Chocolate Cake is not just a treat for the tastebuds—it’s a showstopper on the table. I love how it blends rich chocolate decadence with playful, seasonal fun. Whether for Halloween or just because, this cake always makes a lasting impression.
