New Geode Wedding Cake Rocks

Large purple amethyst cake sparks wedding cake trend.

— -- Traditional wedding cakes have been served up with serious style in recent years and the newest trend taking the internet by storm is the geode cake.

The large amethyst geode cake created by Rachael Teufel of Intricate Icings Cake Design for an event in Denver went viral in January. Teufel was asked to create a centerpiece to represent “joy,” and her inspiration came from a variety of geodes. She took that inspiration for the design of her cake and created a 3-D cavern in the cake, filling it with sugar crystals.

"I knew I wanted to create a show-stopping cake and use the geode as the focal point, creating an awe-inspiring visual experience for the guests," Teufel said.

The edible geode is made from a combination of granulated sugar and rock candy and then crafted with multicolored modeling chocolate, hand-painting and gold leaf. The amethyst geode cake took about 16 hands-on hours to create, in addition to hours of planning prior to making the cake.

Teufel explained that while geode cakes had previously been around, there had never "been one quite like this cake ... it shows off the depth of a real geode."

Since the cake debuted, there have been hundreds of similar cakes created, and Teufel couldn't be happier. "It's been an amazing experience for me as an artist to have the world see my cake and even more amazing to see so many other cake designers using my cake as inspiration. It's still so surreal.”

Rachael Morris of Three Tiers for Cake in North Carolina created this marbled teal geode masterpiece.

Another stunning version was created by award-winning Utah cake designer Carrie Biggers-Burnett.

Claire Marika photographed one of the extravagant gem-filled desserts by Carrie's Cakes, telling ABC News "Carrie creates masterpieces every time" and that "this geode cake is no exception. I love the soft colors, gold foil and rock candy she used to recreate the mineral textures."
