Meriel Frandsen joined us today to share a spooky cake that is perfect for any Halloween occasion!

Black Marshmallow Web Cake


  • 1 cake ready to decorate using American buttercream or Fondant to cover it, but a white color frosting is okay! (No Swiss Meringue Buttercream)
  • 1 black bottle of Edible Art Paint 
  • A flat edge medium size paint brush
  • Marshmallows any size, 2 cups
  • Microwavable bowl 
  • Small bowl to hold paint
  • Spoon
  • Food safe gloves
  • Cake decorations! Toys like spiders or ghost, candy, cookies, or frosting!


  1. If your cake is covered in Fondant, make sure it has dried.  If your cake is covered in an American style buttercream frosting, chill it until the outside has formed a ‘crust’. 
  2. Shake your bottle of black edible art paint until the contents are blended throughout. Pour a portion of the bottle into the bowl and dip your paint brush into the paint. 
  3. Start painting the cake as you would any other surface. It shouldn’t require more than one coat.
  4. Put the cake back in the fridge or let sit until it has dried completely. This could take hours.
  5. When paint is dry to the touch, take out to apply the marshmallow web.
  6. Microwave the marshmallows for 30 seconds in the microwave, or melt on the stovetop.
  7. Stir until it is completely melted
  8. With food safe gloves on, pick a glob up and work between your fingers to create a web like effect and pull around the cake.
  9. Turn the cake and repeat until you’ve added enough ‘cobbwebs’. 
  10. Add decorations and you’re finished!
