Chocolate Spiderweb Layer Cake

Halloween is a season of scary delights and creepy-crawly crafts, and this chocolate spiderweb cake offers the best of all possible worlds! With a host of decadent flavors like a rich chocolate crumb, velvety dark chocolate ganache, and classic buttercream, you’ll find this cake is as delicious as it is spooky. Whether you’re hosting a Halloween gathering or just celebrating the arrival of real-deal fall, a playful chocolate spiderweb cake captures the moment perfectly!

The cake itself is brimming with deep, chocolaty flavor (and a hint of freshly brewed coffee), and has a moist, springy crumb. Best of all, it’s easy to mix up – no need to fuss with creaming butter or hard to find ingredients. Because the cake is so moist, it’s a good idea to take the time to line the cake pans with parchment paper and then grease and dust with cocoa powder.

The spiderweb on top is made by piping white buttercream frosting into warm ganache. Ganache might sound fancy, but with a bit of care, it’s easy to mix up and spread over the cake. Because chocolate chips have fillers to help them keep their shape, I recommend using baking chocolate to make the ganache – it yields the best stability and sheen. To make the web, simply pipe on a frosting swirl and then drag a dull knife out from the center. From there, you’ll want to select a few creepy toy spiders to adorn the cake. The more, the better!

Working quickly, pour batter into cake pans, tap on the counter to dislodge bubbles, and slide into the oven. Bake 35 – 40 minutes, or until a toothpick inserted in the center comes out with just a few crumbs attached.

Set cooked cakes or a rack to cool for 20 minutes, then tip out onto a rack to cool completely, 1 – 2 hours or more.

for the ganache:
When you’re ready to assemble the cake, make the ganache.

Add the top saucepan tot he double boiler and pour in the heavy cream, two-thirds of the chopped chocolate, and a pinch salt to the bowl. Stir until melted. Remove the bowl from heat, and stir in remaining chocolate and corn syrup. Stir until smooth. Remove from heat.

Allow ganache to cool and thicken for 10 minutes, then pour over cake in batches. Use a spatula to spread ganache over cake and guide down the sides. Ganache will thicken as it cools.
