This Spiderweb Cake is an eye-catching dessert featuring rich chocolate cake layers enveloped in a fluffy marshmallow frosting and topped with a luscious chocolate ganache decorated with a spiderweb design made from vanilla icing. Perfect for Halloween or any festive occasion, this cake combines moist chocolate layers with creamy, sweet frosting and a smooth ganache topping.


Ingredients

Scale

For the Cake

  • 1 box chocolate cake mix, plus ingredients called for on the box

For the Frosting

  • 1/2 cup unsalted butter, softened
  • 1 cup confectioners’ sugar
  • 7 1/2 oz. jar marshmallow crème
  • 1 tsp vanilla extract
  • Pinch of kosher salt

For the Ganache

  • 3/4 cup heavy cream
  • 1 1/2 cups semisweet chocolate chips

For Decoration

  • 1 tube store-bought vanilla icing

Instructions

  1. Prepare the pans: Butter and flour two 9-inch cake pans thoroughly to prevent sticking.
  2. Make the cake batter: Follow the instructions on the chocolate cake mix box to prepare the batter.
  3. Bake the cakes: Pour the batter evenly into the prepared pans and bake according to the package directions. Allow the cakes to cool completely.
  4. Place first cake layer: Once cool, place one cake layer on a serving platter.
  5. Make the frosting: In a large bowl, use a hand mixer to beat together the softened butter, confectioners’ sugar, marshmallow crème, vanilla extract, and a pinch of kosher salt until the mixture is fluffy and well combined.
  6. Top with second cake layer: Place the second cake layer on top of the frosted first layer.
  7. Prepare ganache: In a small saucepan, heat the heavy cream just until it begins to bubble. Place the semisweet chocolate chips in a heatproof bowl, then pour the hot cream over them. Let stand for 2 minutes, then whisk until the chocolate is fully melted and smooth.
  8. Apply ganache to cake: Pour the ganache over the assembled cake, spreading it evenly over the top and allowing it to cascade slightly over the sides.
  9. Create spiderweb design: Using the store-bought vanilla icing, frost a spiral on top of the ganache. With a toothpick or skewer, gently drag lines from the center of the spiral outward to make a spiderweb pattern.

Notes

  • Ensure the cakes are completely cool before frosting to prevent melting.
  • Use room temperature butter for a smooth, fluffy frosting.
  • The ganache should be poured when still slightly warm but not hot to achieve a smooth finish.
  • For a more dramatic spiderweb effect, use contrasting colors of icing.
  • This cake serves best when refrigerated and served within 2-3 days.
