Geode Heart Cake

This geode cake would be a beautifully unique cake design for all sorts of occasions, and it is not difficult to create.

Whether you'd like to recreate our heart geode, or you are looking for a more traditional geode cake with an elongated opening, you will be able to apply our simple methods. Enjoy the video!



We used a four layer 6 inch double barrel cake, frosted with a double batch of Classic Vanilla Buttercream. Our double barrel cake has 4 bubble tea straws and two cardboard cake circles. (Center cake board has a little notch cut out.)

Rock Candy (We used three shades: dark pink, light pink, and clear. We used about two rock candy sticks for each shade of pink, and one clear candy stick for outlining the heart.)

Piping Gel

Heart Cookie Cutter or template (ours was about 3.5 inches wide). Use whatever size you'd like!

Gold Leaf (aff.)- Optional

Piping tips: Tip 3 - At the last minute (after making the video) I decided to add a tiny buttercream bead border around the top edge of the cake.

Miscellaneous: Bench scraper, spatula, turntable, small brushes,


Notes for Geode Heart Cake:

*Our geode heart cake is frosted in buttercream, but if you are interested in a fondant covered cake, I would use ganache instead of buttercream to be on the safe side.

I prefer working with a butter based buttercream (rather than shortening) for this design since it becomes firmer much more quickly when chilled.

*Keep in mind that you do not need to do a lot of carving with this cake. Our impression was about 1 inch at it's deepest point in the center. After adding your frosting around the heart, your impression will appear even deeper.

You may find it easiest to carve your cake while it is still partially frozen. (Ours had thawed and so it was more crumbly.)

  1. Very beautiful! I love that the geode isn't overwhelming like some cakes :) Pretty, simple and clever as always. I love it! The Gold Leaf is an excellent touch. :)

  2. As always, beautiful! I love your tutorials Melissa and the filming is the usual impeccable standard. I've been really daunted by geode cakes but you really have simplified the process. Thank you. x

  3. It's a very pretty cake, as always!
    I don't know how you come up with such great ideas. I'm not getting the chance of decorating a lot nowadays but watching your videos are truly mesmerizing and therapeutic.

  4. Absolutely beautiful. Question, where can I find boxes tall enough to transport 4 layer barrel cakes. How do you transport taller cakes.

  5. Your cake decoration lessons are always enriching and it encourages me to go ahead in this field as I like baking.
    It is a very nice cake. Thank you.

  6. Hi Melissa, can you please suggest an alternate for candy rocks that'll give a similar look, as it's not available here in Melbourne?
