Melt the white candy melts as directed on the package.

Follow the directions on the molds to learn how to create the skulls. You will need about 15 small skulls and 6 large skulls. Once you have your skulls made, set them aside until ready to decorate. Look at our Salted Caramel Gold Skull Cocoa Bombs for tips and tricks.

Preheat the oven to 180C/350F/Gas 4 and spray three 9-inch cake pans with baking spray. Set them aside.

Using an electric standing or hand mixer, beat the cake mix, eggs, butter, and milk until smooth.

Divide batter into the three prepared cake pans and bake in the oven for 25-28 minutes or until a toothpick inserted into the center of the cakes comes out clean.

Allow the cakes to cool for 5 minutes in the pans before turning out onto a wire rack to cool completely.

When the cakes have cooled and before assembling the cake, level off the dome that may have formed during baking using a cake leveler or serrated knife.

To make the frosting, use a handheld or stand mixer with a paddle attachment and combine butter, powdered sugar, vanilla, and heavy cream in the bowl. Beat on medium speed until creamy, smooth, and stiff peaks form. Reserve a couple of tablespoons as "glue" to hold skulls in place.

To assemble the cake, place one (cooled) layer onto a 10-inch cake board (secure in place with some frosting on the bottom).

Evenly spread 1 cup of frosting onto the cake layer using a spatula.

Place the second cake layer on top and spread another cup of frosting into an even layer.

Place the final top layer and add a thin layer of frosting to add a crumb coat layer around the cake. Place in the fridge for 1 hour to firm up.

Use the remaining frosting to completely cover the sides and top of the cake. Smooth out with a spatula. Place in fridge for another hour to chill and firm up.

Build a pile of skulls in the center of the cake using the reserved frosting.

Use the red icing to create a drip effect around the top edge of the cake, as well as squeeze some into the eye sockets to drip from the skulls onto the cake. Enjoy, and Happy Halloween!
