How to Make a Construction Cake for a Construction Birthday

My son was turning four and obsessed with construction equipment, so when he saw this construction cake for his birthday he was super excited. I wanted to throw him a construction birthday party to celebrate his love for construction equipment. We have yellow Tonka Trucks, bulldozers and backhoes he loves to play with. I had to be a little creative, since my Little Face was allergic to chocolate. I could not use the standard chocolate cookies for the dirt. See how I made this fun construction cake.

Ingredients for Construction Cake

2 boxes cake mix
2 cans of white icing
8 sheets of graham crackers (or chocolate cookies)
1/2 cup brown sugar
small butterscotch morsels for decorations (or chocolate morsels)
small construction vehicles

Directions How to Make a Construction Cake

1. Bake two cakes in round cake pans and allow them to cool. Use a little left over batter from one of the cakes to bake a cupcake. This is where I cheat. I just use box cake mixes, since it is easy to make and I am usually rushed for time during the birthday week. If you want you can make two cakes from scratch and have them ready to go. Knock yourself out!.

2. Stack the cakes using a little icing between the layers. I used two different flavors of cake. One orange dreamsicle and one confetti. Orange to represent the construction signs. Confetti just because it is so fun.

3. Using the white icing and a cake spatula, make a crumb coat around the entire cake. Let this sit for about 10 minutes in the refrigerator to set. Next add another layer of white icing. This is how to get a perfect white icing on the outside with no flecks of cake in the icing.

4. Next cut off the top of the cupcake and turn it upside down on the icing. Now we want to create a small hole in the cake. Take a bread knife and cut out an indention in the cake. I tried to go through just the top layer of cake and just cut a little piece out. Cover the cupcake and the indention with icing. No need to be perfect here we are going to cover it with dirt soon.

5. Next to make brown dirt smash the 8 graham crackers or use a food processor. Once really crumbly add 1/2 cup of brown sugar. This will make the dirt really look like dirt.

6. I piped a little white line around the outside of the cake to hold the dirt on top. Next start sprinkling the graham cracker dirt on the top of the cake and on top of the cupcake hill. Be careful not to get it on the sides, unless you want an entire dirt cake.

7. I added a few candy sticks to resemble wood stacked off to the side. I used a little bit of icing to secure them together and to the cake.

8. To add some rocks, use butterscotch or chocolate morsels around the cake. I spread the dirt around the base of the cake and I wrote the words Happy Birthday on the side using the butterscotch morsels. For decoration I added some small construction vehicles moving some dirt and rocks around. This seemed to make the construction cake come alive with all the yellow construction vehicles around.

I baked the cakes the night before and just threw this construction cake together in about an hour before the party. My uncle loved it so much he thought I bought it. My little face’s construction birthday party was a huge hit and everyone loved the cake. This is probably one of the easiest cakes I have ever made, and it was the most fun. My mother passed away earlier last year. I saw she had already purchased some construction books for him, so I centered the construction birthday party around the books. We gave them to my son and told him Nana picked these out especially for him.
