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

  1. I start by preheating my oven to 350°F (175°C) and greasing two 8-inch round cake pans.
  2. In a large bowl, I whisk together the dry ingredients: flour, cocoa powder, baking soda, baking powder, and salt.
  3. In another bowl, I beat the eggs, then add both sugars, buttermilk, oil, and vanilla. I mix until well combined.
  4. I gradually add the dry mixture to the wet ingredients, stirring gently. I pour in the hot water (or coffee) and mix until smooth.
  5. I divide the batter evenly between the pans and bake for about 30–35 minutes, or until a toothpick comes out clean.
  6. Once baked, I let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
  7. 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.
  8. I pour the ganache over the top of the stacked and leveled cakes, letting it drip slightly over the sides.
  9. 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.
  10. I let the ganache set before slicing and serving.

Prep time: 25 minutes
Cook time: 35 minutes
Cooling and decorating time: 1 hour

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.
  • I use orange-tinted white chocolate for the web design for a colorful Halloween theme.
  • If I want a gluten-free version, I substitute the flour with a gluten-free blend.

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. Spiderweb Chocolate Cake

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.
