How to Make a Fire Truck Cake
A fire engine is a great idea for kids’ birthday celebrations. It is a fun cake to have, but it also involves so much learning. Kids are always so fascinated with the fire truck, its color, the siren, the hose, and the firemen. Here’s how I made my Rhea’s fire truck cake tutorial.
It was Rhea’s birthday recently, and she asked for a fire truck cake. She loves the TV series Fireman Sammy with the fire engine. Also, not long ago, she had the opportunity to visit a fire station and got to ride in a fire engine with the firemen. It was a wonderful experience she speaks very fondly about. So it just made perfect sense that she wanted to have a fire engine cake.
It was also an opportunity for me to share with you how I made this cake. So, of course, I kept the camera on and hope that you can see how simple and easy it is to make this cake.
Recipes
- Cake Recipe – The cake recipe below is my moist vanilla Pound cake recipe but baked in a sheet pan. I colored the batter into a few different colors for a tie-dye effect. You can find more cake recipes here – 30 plus layer cake recipes
- Frosting – White Chocolate Ganache – I’ve used Ganache today because it’s hot and humid (40 C here in the summer), but any other buttercream or frosting will work. You can find a huge selection of my frosting recipes here – 30 plus buttercream frosting recipes.
- Fondant – This is marshmallow fondant using magic colors extra red. You can find all my fondant recipes here.

How to Make a Fire Truck Birthday Cake
Rainbow vanilla cake
- Prepare – Preheat the oven to 350°F/ 177°C/ Gas mark. Prepare a 15 x 17 sheet cake pan for baking – grease and line with parchment paper. If you don’t have a sheet pan, you can also use 2 x 8-inch square tins.
- Dry ingredients – In a bowl, combine flour, baking powder, baking soda, and salt. And set aside.
- Wet ingredients – In the bowl of a stand mixer, cream butter and sugar until light and fluffy. Add eggs one at a time until well combined. Use a spatula and scrape the sides of the bowl when necessary. Next, add the flour and milk mixture in three batches. Then, add the vanilla extract.
- Rainbow batter – divide the batter into 5 or 6 bowls and add a few drops of gel food colors in each. Combine well until you have the desired color
- Bake – Pour the batter into the prepared sheet pan and bake on the middle rack for 50 to 55 minutes or until a skewer inserted inside the cake comes out clean.
Frosting – White chocolate ganache
- In a large bowl (microwave-safe), combine the white chocolate and heavy cream. Heat for a minute or more until all the chocolate is melted and smooth. Add the vanilla extract and combine well. Cover and leave to set in the refrigerator for a few hours overnight.
Prepare
- Template – Print the picture of a fire truck – the size you want. I used A4 size paper. You just need one image on paper to use as a guide. I printed a few copies from different angles so I could use them as inspiration. But you can even use pictures on your phone.
- Cake board – Cut a rectangular piece of foam core board or piece of cardboard the size of your truck as per the paper. Mine was about 15 x 5 inches. Using strips of foam core, make feet for your cake board under the cake. This will keep the cake elevated so you can add the wheels later.
Pro tip – The edges of the cake should be in line with the edge of the cake board.
Carving the cake
- Carve the cake as shown in the video. Cut the cakes, arrange the pieces, and stack them according to the template. Cut the sheet cake in three lengthways. The back has two layers of stacked cakes, and the front has three layers of stacked cakes cut at an angle.
- Stack two pieces and check the height with your template. Use the third piece to create the front of the cake. Shape the front, as shown in the video.
Frosting the cake
- Ganache – Once you have carved the shape. Frost the cake with frosting between layers and crumb coat the cake with a thin layer of frosting. Chill the cake for 15 minutes. Then, add more frosting and frost the truck, making sure you have nice square corners. Smooth the cake with a flexible smoother and let it chill until the frosting is firm.
Pro tip – Don’t forget to brush the layers with simple syrup before frosting. - Fondant – Roll red fondant and cover the whole cake, as shown in the video. Cut excess fondant from around the cake. Use a cake smoother to smooth and create square corners around the cake.
Fondant cake board
- For the board, use grey fondant. Roll and cover the entire board. Use a texture mat, as shown in the video. Use the cake as a guide and remove some fondant from the center to secure the cake. (See the video) Use hot glue and secure the cake in place.
Pro tip – The hot glue is only to secure the board to the board; make sure it does not touch the cake.
Complete Firetruck design
- Wheels – Use small cookie cutters for the wheels, as shown in the video. Cut a large black fondant disc and a thinner red fondant disc. Use white for the center design. And use a tweezer for the tire marks.
- Panels – Use black fondant for the truck bottom panels.
- Sutters – And use grey fondant with CMC for the shutters. Alternatively, you can also use gray buttercream frosting, which can become quite smudgy if not done correctly.
- Ladder – White fondant with CMC for the ladder.
- Fire hydrant & Hose – Grey and yellow fondant for the hose.
- Borders – White and black fondant for the borders. I used a strip cutter to make the white borders for the shutters. Use a fondant extruder for the black spaghetti for the doors and mirrors. But you can also pipe the borders with black royal icing and a #3 piping tip.
- Windows – Make the front and back windows.
- Silver metallic is used for the road on the board, as well as the shutters, hose, and headlights.

Notes
- Use a butter-based cake recipe to add more stability to novelty / sculpted cakes.
- Always keep the cake well wrapped in plastic to prevent it from drying out.
- Chill the cake well or freeze the cake for an hour before carving. This helps to create fewer crumbs.
- Use firm, sturdy pieces of cardboard or foam core for the cake base.
- Brush the cake with simple syrup after carving and before frosting.
- When frosting a novelty cake, use a light crumb coat. This helps to hold the crumbs in place.
- Chill the cake between the crumb coat and the frosting. Use a bench scraper to get sharp corners.
- Use a thicker fondant so it creates nice sharp corners using a smoother.
- Let the fondant dry for a while before you start attaching other details. It becomes easier to stick fondant when it is less tacky.
hello, if I have to use 9*13 inch baking pan for baking this cake, how do I measure ingredients. I’m lost in converting . could you please help. thank you for your wonderful tutorial.
You can use this same batter for a 9 x 13 cake pan, too. The cake will be slightly thicker. Thanks
I tried a few of your recipes and think your measurements have lots discrepancies. Mine still turn out with adjustments but, please check.. n I do like this recipe which turns out good but your wet ingredients quite short. Thank ?
Hey Jo, not sure I see the discrepancies. Cam you please be more detailed?
There is 500 grams of flour and about 560 grams of liquid ingredients if you use 5 large eggs plus 1 cup of milk. Of course there is still the sugar and butter.
This is a good cake batter. The batter is not very loose but it make just the right texture for carving.
Thanks
Hi Veena, I am going to attempt to make the fire truck cake for my nephews birthday! Can I ask does it make any difference to the taste (too sweet etc) whether I use the white chocolate ganache or dark chocolate ganache under the fondant? I am going to make a vanilla cake.
Hey Toni, White chocolate ganache is sweeter than dark chocolate so yes, it will be sweeter but kids don’t mind it really. There is no problem using dark chocolate ganache under fondant, provided you don’t roll it very thin which usually is never an issue for most people.
I made a fire truck. I made a firetruck.. I did.. thank you so much.
Thank you, Agend. So happy you had success with this tutorial. I am see how proud you are. Thank you so much for coming back to write this feedback. Have a wonderful day.
