Volcano Cake Recipe

Wow, it’s been a while since I’ve posted on any of my blogs. Tsk! Tsk! I just completed a manuscript for Entrepreneur Press on how to Start Your Own Photography Business or Studio, so things have been pretty busy.

To get back in the swing of things, I’m going to start off with a Volcano Cake recipe my hubby and son made for the Cub Scouts banquet last month. They did a great job and it was a big hit. Plus they won the prize for most creative cake (beams the proud mom).


This one takes some time, so make sure you’re patient and have at least a few hours to prepare this cake before you begin. Also, make sure you ask an adult for assistance. Preparing the lava mixture and setting it up so it erupts correctly can be a bit tricky.

4-6 baked round cakes
Brown (chocolate) frosting
Green frosting (and other colors if desired)
1 egg
Red food color
1-1/2 teaspoons sugar
1/3 lb dry ice
Aluminum foil
Large serving tray
Hot water

Make 4-6 round cakes in any flavor that you want. Each cake should be approximately eight inches in diameter. You can make these cakes from scratch or you can use any box cake mix. Make sure you allow the cakes to cool for at least 30 minutes before you begin to cut, create and frost the final cake.

Place one cake on a large serving dish. Then cut each successive cake around the outer edge so it’s just a little bit smaller than the cake before.

Stack the cakes on top of each other one at a time using the brown frosting to secure the cakes in place. Each cake that you place on top of another cake should be a little bit smaller than the one underneath it. When you’re done, the cakes should be in a pyramid shape, with the smallest cake on the top.

Cut a small circular hole in the center of the top 1-2 layers of cake (You may want to do this before you stack the final 1-2 layers on the top).

Using a small piece of aluminum foil, line the hole in the center of the volcano cake.

Frost the entire outside of the cake using the chocolate frosting (leaving the hole at the top open), smoothing out the step-like ledges. Then use green frosting to make trees or other vegetation. You can also use other colors of frosting to decorate the cake in any way you want. (Note: for green frosting I use a cupcake frosting tube such as the one from Betty Crocker. However, you can make green frosting with a cup of vanilla frosting that has a few drops of green food coloring stirred into it.)

Now it’s time to make the lava. Crack open one egg and place the egg white in a small mixing bowl (This is best done by cracking open the egg very carefully then passing the yolk back and forth between the two egg shell pieces while allowing the rest of the egg to drip into the bowl). Add 1-1/2 teaspoons sugar and 2-3 drops of red food coloring into the bowl and beat with a fork until it forms a thick, foamy texture.

Place a few small chunks of the dry ice into the foil-lined center of the cake and pour in the red egg mixture. Don’t worry, nothing will happen to the lava mixture until you complete one final step.

When you are ready to produce this exciting special effect, bring the cake to the table or wherever you want to serve the cake. Pour a few ounces of hot water into the lava and dry ice mixture in the center of your cake. Your cake will then erupt with the red foamy and white smoke for several minutes!

Serve and Enjoy!

    what is dry ice?
    where do you get dry ice?

    please help as i need to make a volcano cake and yours sounds really nice!!

  2. Dry ice is solid carbon dioxide that is used as a cooling agent. We purchased ours at Albertsons grocery store, so check with your local grocer to see if they have it. Have fun!!

    I want to know if the egg white mixture is safe to eat?

  4. The egg white mixture is perfectly safe to eat, but not the actual pieces of dry ice. The "lava" may not be very appetizing, although I did read somewhere else where the mixture was flavored with strawberry extract.

  5. when making lava cake with marshmellow fluff, the dry ice comes in contact with the lava. Is it safe to eat?

  6. This particular recipe does not use marshmallow fluff, although that sounds interesting. But see the previous comment about the egg mixture coming into contact with the dry ice.
