Total Time:

18 to 24 servings

  • 2 (18.25-ounce) boxes red velvet cake mix (recommended: Duncan Hines)
  • 2 2/3 cups water
  • 1 cup vegetable oil
  • 6 eggs
  • 3 (12-ounce) cans chocolate whipped frosting (recommended: Betty Crocker)
  • 1 (6.4-ounce) can green decorating icing (recommended: Betty Crocker Easy Flow)
  • 1 (6.4-ounce) can red decorating icing (recommended: Betty Crocker Easy Flow)
  • 1 (6.4-ounce) can orange decorating icing (recommended: Betty Crocker Easy Flow)
  • 1 (6.4-ounce) can yellow decorating icing (recommended: Betty Crocker Easy Flow)
  • 1 (.68-ounce) tube yellow gel decorations (recommended: Cake Mate)
  • 1 (.68-ounce) tube red gel decorations (recommended: Cake Mate)

Preheat oven to 350 degrees F. Spray 2 (8-inch) cake pans, 2 (10-inch) cake pans and 1 (6-inch) Bundt pan with cooking spray and set aside.

Beat cake mix, water, oil, and egg whites in a large bowl with an electric mixer on low speed for 30 seconds. Scrape down sides of bowl and beat for 2 minutes on medium speed. Divide batter equally between prepared cake pans.

Bake 8-inch cakes and 6-inch Bundt cakes in oven for 35 to 40 minutes and 10-inch cakes for 45 to 50 minutes, or until tester comes out clean. Remove and cool completely.

To assemble, use a serrated knife to slice off the tops of the 8 and 10-inch cake so the surface of each cake is flat. Place the cut tops into a large bowl and break up to from large crumbs. The crumbs will be used a "lava rocks" at the base of the volcano. Slice the bottom off the 6-inch bunt cake so it sits flat.

Spread a thin layer of chocolate frosting between the 10-inch cake layers and stack. Spread a thin layer of chocolate frosting between 8-inch cake layers and stack. Place another thin layer of frosting on top of the 8-inch layer cake and place the bunt cake cut side down on top. Place a dollop of frosting on top of the 10-inch cake and carefully, place 8-inch cake on top and center of 10-inch cake.

Use a serrated knife to trim edges around the tops of both cakes to create a cone shaped cake. (Make angled cuts downward and leave a round base on top for icing to "flow" from.)

To decorate, frost outside of entire cake with remaining chocolate frosting. Place the cake crumbs around the base of the cake. Pipe green icing around the entire bottom of the cake for "grass". To create "flowing lava" pipe red icing a quarter from the top of cake in downward strokes to the middle of the cake with ribbon tip. Repeat technique with orange icing, starting almost at top of cake and ending where red icing begins with slight overlap. Repeat technique with yellow icing starting at the very top of cake and overlap orange icing. Drizzle yellow and red gel coloring around the very top of cake.

For the smoke effect place a few pieces of dry ice into glass candle votive. Place the votive into the hole of the bunt cake. Pour a small amount of warm water into the votive and watch it smoke.

    Made this for my Granddaughters 1st Birthday Party .. It was a huge Hit ! Gave me the courage to try something harder. Thanks Sandra: If you want something totally Different Try this .. not as hard as it looks and dont forget to add the LOVE !!
    My daughter loved it and I had a blast making this for her. It was used in her Hawaiian themed turning 11 birthday party. I had 18 kids with 7 adults present and tons of cake left over! We changed it up a bit by using our own flavor of cake mix and added the volcano to a sheet cake.
    Then we added palm trees, little hula girls, and mini umbrellas. I used sprinkles for the sand and water. It turned out cute!
    We had lots of raves! Thanks for sharing!
    This is tremendous - I went to the dollar store and bought some mini dinosaurs and palm trees to decorate the volcano for my sweetie's 40th birthday. It was a HOOT!
    I made this for my son's seventh birthday and it came out great and was super easy! I put it on top of a sheet cake and used some lego men to "run" from the volcano. The one caution I have is regarding the votive candle holder - - DO NOT do it!!! The guy at the ice place told me it would shatter in the cake. Use a dixie cup and you'll be OK. But the cake was great and I would do it again!
    In my science class we were learning about natural disasters and we had to do a project. The project was to make our own disaster my group had volcanoes and what quickly popped into my head was the episode I saw of you making this cake. Me and my friends made the cake (without any problems) for the project and our teacher said it was the most creative thing ever. But at the end we gave a shout- out to you; Sandra Lee for getting us an A+ tasting and intelligent Volcano. :)
    I loved this It is soo awsome and good!!!!!
    My 12 year old daughter and I made this cake into a Pokemon themed volcano. This cake was very easy to bake and assemble. We used the Pampered Chef measuring bowl to as the baking dish for the top part so we wouldnt' have to buy small bundt pan and it worked perfect. For the colored icing, we used white store-bought frosting, gel food color and plastic baggies snipped at the corner to make red, orange and yellow "lava" stripes. Our local shops do not sell dry ice but I was able to find it at a welding shop.
    this was such a great cake...
    And it was very easy...(btw, i've made it 4 times already!!!!!)
    just a little time consuming and the ingredients (in all)
    were a little pricy but it was sooo worth it!!!!!!!!!!!!
    You can get Dry Ice from Publix Suoermarket!!!! For $1.29 a pound
    Talk about bang for your buck! This is an real crowd pleaser. The directions are far more difficult than this calls for but bare in mind she has to fill a half hour show. You'd have to be some kind of novice to be challenged by this one! All said I was out maybe $12 and spent 20 minutes hands on.

    The steps I took:
    Take 2 boxes of any kind of dark cake (I used Moist Delux Devil's Food)
    Prep your pans by greasing and taking a 1/2c. of the cake mix to "flour" them. Shake the left over into your mixing bowl. Mix & bake according to the directions. I used a regular Bundt pan so I put that one in the oven 1st. By the time I had the 2nd mix done it was perfect time to add the two rounds to the oven. They all came out at the same time,

    I let them cool in the pans then I plopped the rounds one atop the other and the Bundt on top( no cutting off the tops, it's a volcano not a pyramid. Imperfection is okay;). Trimmed to Vocano shape, frosted, drizzled with the icing and dropped the ice in the votive with the water and VOILA! Instantly thrilled kiddos. I did get one of those tubes of mini dinosaurs to put around the base. I love this, fast ,simple and it thrilled the kids! One last thing. I found dry ice at a welding supply store of all places if that's helpful. Who knew? Thanks Sandra Lee!
    While the idea is great, the execution was not as simple as shown on the show. Two cakes mixes made about 1/4 inch high cakes, so I used 4 cake mixes and eight layers (three chocolate fudge) to get the desired height. The recipe also talked about adding egg whites, but never said anything about separating the eggs, so I used the whole egg, as in the cake box directions. The final product was very cute, but we couldn't find any dry ice in our area. I stuck the sparkler candles in, but it just wasn't the same effect. Our 10 years old grandson still enjoyed the cake.
    This recipe is so easy to make. Just follow directions. I made my own choc. butter cream frosting. I also cut a small juice can in half. I used sterno in the juice can to tuck into the volcano. Instead of "smoke" we had flames!
    I did vary the ingredients to take out preservatives and artificial colors. Finding the dry ice was the hardest part. My husband thinks that a larger glass would be better for more smoke. Overall, it was fun and easy to do. Thanks Sandra Lee!
    This cake was fun to make and the kids loved it! The crazy little five year olds crowded around and could not wait to get the first piece. It tasted very good and is a must do for little ones
    What a great idea and easy to make as well! Thanks Sandra for anohter inspiring recipe!
    This cake was easy, but not as easy as Sandra made it out to be. It had a good effect, but not worth the money and effort. The cake was way to sweet. Janice...5 stars just because it looks fun to do. Rate only if you make it. It gives a false review of a recipe.
    man this cake was sooooooooooooo good i loved it man my family and freinds loved it too!!!!!! thank you so much for teaching me this great recipe
    This is something I know would be a winner!! My new daughter-in-law had a hawaiian theme bridal shower because she and my son were getting married in Hawaii. There was a volcano cheese dip on the table of other types of Hawaiian foods. The hostess put dry ice in the middle. I thought this was so cool!! But a cake!!! Wow!! I am definately going to do this one!!
