What’s a Geode Cake?

It’s a cake that mimics the cavities in some rocks lined with crystals or minerals. Usually, bakers create carvings within the cake and carefully add lots of colorful rock candy or isomalt shards (a sugar substitute made from beets). This is a very meticulous step, as the minerals must look like they are spilling out of the slicings. Much like surgeons, pastry artists often use kitchen tweezers to complete the task! The result is a
beautiful cake that looks like it is filled with gems and crystals!

Usually, geode cakes consist of a layered sponge cake base, carved and then frosted with buttercream or fondant. The cake can be any flavour you like: chocolate, birthday cake… it could even be a carrot cake if you wish. Some advise against eating the candy to properly enjoy the cake, but the faux crystals should still be totally edible. The combination of crunchy candy and soft cake yields a special mix of textures when eating the cake. Rest assured that it will not feel, or taste, like snacking on rocks, though!

It is unknown where the idea of the geode cake originated, or what inspired bakers to put crystals in a cake! However, there may be a story behind it, as unexpected as the cake itself. In the last couple years, the rise in popularity of new age spirituality caused crystal sales to reach new heights. Indeed, crystals went from something reserved for geologists or “hippies” to a beloved jewellery, decoration, and even energy-uplifting item. It makes sense that one of the places crystals ended up is our dessert plates. Crystals on a cake, why not?

Recently, the geode cake has gained in popularity and emerged as a trend in the dessert world. The cake’s sculptural look, particularly when it features multiple layers that add to the dramatic effect of the carvings, make it particularly popular for weddings. Luckily, you don’t need to get hitched to enjoy one of these gorgeous cakes!

This cake is definitely one of the more mesmerizing baking trends to have surfaced in the last few years. Now that you’re familiar with the geode cake, do you feel any unusual crystal cravings? If you do, we strongly advise you to stick to edible crystals…or better yet, get your own geode cake near you!
