30 Beautiful Geode Cakes And How to Make Your Own

Being the avid kitchen enthusiasts we are, it’s no surprise that we’ve learned how to bake all manner of things in order to satisfy our own sweet tooth. One of our favourite parts of baking often is keeping up with the coolest trends in the treat world and trying them at home. That’s how we found ourselves looking for tutorials and inspiration to try our hand at making beautiful geode cakes!

One of the best tutorials we’ve found so far was this one from Tasty. They teach you, step by step, how  to turn any cake flavour of your choice into a stunning piece of art inspired by precious stones. Check out their finished product! They made a stunning white cake with a dark to light teal ombre geode section cut into the side. The surprisingly realistic texture is created using delicious, colourful rock candy!
