A fire engine is a great idea for kids' birthday celebrations. It is a fun cake to have but 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.
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.
2 cups Sugar, 1½ cups Unsalted butter, 5 large Eggs, 1 cup Milk, 2 tsp 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.
6 drops Gel food colors
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
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.
18 oz Chocolate, 1 cups Heavy cream, 2 tsp Vanilla extract
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 can 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.
Carving the cake
Carve the cake as shown in the video. Cutting cakes, arrange the pieces, stacking 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.
½ cup Simple Syrup
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 chill until the frosting is firm.
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.
500 grams Marshmallow Fondant
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.
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.
200 grams Black Fondant
Panels - Use black fondant for the truck bottom panels.
Sutters - And use grey fondant with CMC for the shutters. Alternatively, you can also use grey 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, the hose, and the headlights.
