Truck Birthday Cake How To

truck cake construction party
“Truck truck” a cute little nearly two year old voice said when I asked him what type of cake he would like for his birthday. The next day the response was ‘raa raa’.  He swapped back and forth between the two answers like he was playing ping pong.  So the final decision came down to what he said on the day I started making it.

When it was finished and in the fridge he said saw it, smiled a beaming smile and then said ‘yuck yuck’.  It took me a moment to realize he thought it had real dirt on it, which I have to agree would be yuck yuck.  After giving him a quick explanation and a little taste of ‘dirt’ he loved his ‘truck truck’.

To make your dump truck cake you will need:

* 1 kg (2.2 pounds) white fondant (colour it to make 900g (31.75 ounces) yellow and 100g (3.53 ounces) light grey, to make the light grey mix a little of the black fondant with the white).

* Yellow gel food colouring

* 1.5kg (3.31 pounds) Black fondant (you will have approximately 200g (7.05 ounces) left over, store in two ziplock plastic bags for a later date).

* Thick cardboard to support the cake

* Aluminium foil

* Cake board.  The one I used was 45cm (17.72 inches) x 40cm (15.75 inches)  Tip:make sure it will fit in your fridge before you put the cake on it.

* double quantity of this moist chocolate cake

* ganache (see details further down in step 5)

* non stick baking paper

* isomalt or sugar for windows

* 2 packets of oreos for dirt

*silver luster dust

*rolling pin, knife & pizza cutter for cutting the fondant

* optional rock candy geodes for in the back of the truck

* rectangle cake tin Cake Tin Rectangle Extendable (or see video for alternative) slightly bigger than the cake template.

* Truck Template Download includes the template of the make ahead fondant pieces and template for the cake pieces for the truck cake.

Truck Cake Template
Template for cutting the cake and the fondant pieces (note this is a digital download you will need to print it out). After payment do not close your screen, follow the links to download the template. For tutorial click on truck image.

Step 1. Make the fondant details. This can be done up to a month ahead. You will need to leave at least a few days for the fondant to dry out before you want to decorate the cake. The downloadable template gives you a guide to cut out all the ‘make ahead’ fondant pieces. Watch the video for instructions.

Step 2. Once the fondant has dried hard make the centre of the wheels, this can be done ahead.

Step 3. Cover your cake board and make your cardboard cake board in the shape of the template

Step 4. Make your chocolate cake. I used a double quantity of this chocolate cake recipe and baked it at 150C (302 degrees Fahrenheit) for 3 hours 20 minutes. Place an empty baking tray on a shelf above it to shield the top for heat. Check that it is cooked through to the centre by inserting a knife into the middle. You can do this the day before you want to decorate your cake (ie 2 days before the party). Once it is completely cool cover in plastic wrap to store.

Step 5. Make your ganache and leave in the fridge overnight. The start of the chocolate cake recipe video shows you how to make ganache  For the consistency of ganache on this truck I used 875 g (30.86 ounces) chocolate, a mixture of milk and dark chocolate, with 320ml cream.  If you are not covering the rocks in the back of the truck in ganache you will only need half as much.

Step 6: Cut out and decorate your cake (either on the day of the party or the day before the party depending on the time of day) Full instructions on the video.  Store in the fridge until ready to use (If making ahead do not add you truck tray until the day of the party or it may crack or split when becomes moist in the fridge).

Step 7: Fill your isomalt windows and add to the cake  If using sugar not isomalt follow the sugar decorations recipe Do this on the day of the party.

Step 8: Take a photo and upload it in the comments section below.

Popping sugar traffic cones: Use a traffic cone toy and reusable food grade casting gel (available here) to make a mold of your traffic cone.  Melt some candy melts or nestle white chocolate melts and colour using oil based red and yellow food colouring.    Fill the mold, wait a until it starts setting a little and tip it out.  Fill the middle with popping sugar or filling of choice.  Seal off the top with more melts.  Set in the fridge or freezer and then tip push out of the mold.

    Can you tell me about what the finished size is of the cake?

  2. Kayla says:

    can i use bette crocker icing instead of the ganache?

  3. Korey says:

    I’ve never really worked with fondant except for little accent pieces. You make this look very easy and wanted to make it for my son’s birthday. In your opinion, do you think an amateur would be able to make this? And which fondant recipe do you think would taste the best and be the easiest to work with? Thanks in advance for your response!!

    • tish says:


      i have never worked with fondant before, but i think mine turned out pretty awesome! i used pettinice pre-coloured icing i found it great to work with but i recommend making the bucket 4 weeks in advance in the hot seasons because i made mine 1 week in advance and it didn’t hold up for very long at the venue. Although the decorations i made a month in advance didn’t budge.
      also i used caramel flavouring for the yellow fondant and that went down a treat!

    • Ann Ann says:

      Hi Korey, yes i think if you follow the instructions and use the template it should work for you. I like Duff fondant but I use many different brands.

  4. Teresa says:

    HOw do I order the templates

  5. Christy Hughes says:

    Thank you so much! These templates just saved the day! Great videos.

  6. Tish says:

    Hi Ann

    Silly question but in your choc cake recipe it says you need 8eggs, does that mean I will need 16eggs for the dump truck cake?

    Thank you

  7. Juna says:

    Hi Ann
    Thanks again. Everybody loved the cake. One of the children thought it was a toy. :)

  8. selena says:

    hi ann
    i just brought your truck template and cant wait to try it for my nephews 5th birthday this weekend. So wrapped that it was the first tutorial that i looked at and it came with templates and all. ooohhhh so exctied to try it, cant wait.
    Great tut, thank you soooo much, you work looks brilliant and i look forward to seeing what else you have on your website.

  9. Luisa says:

    Hi Ann,

    I just purchased your templates & am very excited to try this. I know you mentioned your cake fed 20ppl, we have 50 coming to the party. Do you think the truck would be too heavy to sit on top of a slab cake? I’m just trying to figure out how I can feed more people.


    • Ann Ann says:

      Hi Luisa, you could sit it on top of a slab cake if you put a cake board under it like you would with a tiered cake Or enlarge the template and make a bigger truck

    • selena says:

      hi luisa
      i believe that the birthday cake is the statement of the party and the size/quantity doens’t necessarily have to be enough to feed everyone, its the look of the cake that you want to stand out. You usually have other desserts and find that people only want a small piece of birthday cake. everytime i have have made cakes smaller than the amount of guest i still manage to have lots of party cake left over. my family is obsessed with desserts, but if your not having lots of other desserts maybe just make another small cake or cupcakes to feed more people.

  10. Juna says:

    Hi Ann

    Thank you very much for your detailed Dump truck tutorial. I have purchased your templates. My son loved your dump truck cake when I showed him. His birthday is this month, so I am so glad to found your website just on time. Thanks again.

    Hi Ann,
    Just want to let you know I love your channel and watch all your videos. I have been decorating cakes for about 2 years or so now and you have taught me so many skills and hints to make my cakes just that much better.

    I have just downloaded your tip truck template and as i am trying to replicate a NSW RFS fire truck, do you think this templete would be easy to alter?

    And is isomalt easy to work with or do you recommend having a few tries at it before i make my windscreen and windows?

    Thanks keep up your amazing video you are an amazing decorator
    Hannah :-)

    • Ann Ann says:

      Hi Hannah, If I were you I’d printout some pictures fo the actual truck you want to make and use that as your template instead. The firetruck is quite different. And the wheels from the lightning macqueen cake tutorial might be better for it.

  12. yasheen says:

    hi, love your recipies.
    please advise where can I purchase the food grade casting gel.

    thank you

  13. Kriskell says:

    Hi Ann,
    We are making a truck cake for my sons 3rd Birthday. The fondant is done I just have to make the cake. I was wanting to start decorating the cake two days before the party. Is this advisable?? and if so, can I store it in the fridge until the day of the party? Cheers.

    • Ann Ann says:

      hi kriskell, if you need to make your cake that far ahead then make sure you use some simply syrup to keep it moist – see the princess cake video for how-to do that. I would recommend that you do not put the back scoop on until the day of the party but the rest will be fine in the fridge.

  14. Jaime Lee says:

    Hi, I am interested in ordering the dump truck template. I am wondering how many people does the cake roughly feed?
    Thank you :)

  15. KRISTIN says:

    Hi Ann!
    Thanks so much for your great tutorial. It worked perfectly. Thank you for taking the time to put it together.

  16. kimbly says:

    Hi Ann, I tried to make you dump truck for my sons birthday. Just wanted some pointers for next time. I found my tray ( back of the truck) broke. I made it a week before i made the cake. I used satin ice fondant, not sure were i went wrong. Apart from that it turn out ok for my first attempt at a cake that is up on a stand.

    • ann ann says:

      hi kimbly well done, If the back of the tray broke you have hidden it well as I can’t tell from the picture, your cake looks great. You made it a week before so I imagine it should have been fully dry by then. Was it still moist?

      • kimbly says:

        Hi Ann, the tray didn’t break until a few hours later after this photo was taken. Just before i served it up for my son. i didn’t put any tylose or hardening agent in the fondant. could that be the reason it broke. Or the weather was very wet that day. I really enjoyed making this cake. Thank you so much for your tutorials there wonderful. My son loved it either way he was so excited.

        • ann ann says:

          That is disappointing, Not sure on that one, I have not had fondant that is set hard go soft again unless it has got very wet.

  17. Christian Castro says:

    My girlfrind and I worked on creating your Dump truck cake and I want to share with you the picture of our first attempt.

    • ann ann says:

      Hi Christian, This looks fantastic great job, I will have to do a youtube video with pics of everyones creations :)

  18. Christian Castro says:

    Hi Ann, you are definitively an artist. I just purchased the truck templates from your site. I would like to ask you, for how much would you sale this cake? Thanks!

    • ann ann says:

      Hi Christian, How much you charge for a cake like this depends on which country you are from, I suggest looking at websites for cake decorators or cake artists in your country and base your prices on detailed 3D cakes.
