For my son’s 3rd birthday we created a construction cake (he loves construction vehicles). My sister-in-law made this very cute cake. We had so much fun with it.

She used brown sugar for the dirt roads and used real toy construction vehicles. She really put detail into it. We then used a large dump truck to serve chips and a plastic hard hat for snacks. We purchased new sand rakes and shovels to serve the salads. As you can see my son just wanted to get in there and play construction on the cake itself!!!

Inspired by the other unique birthday cakes found on these pages I created these 2 cakes for my sons’ 4th birthday. Why 2? One for his actual birthday and one for his party, (not to mention the one I also made for him to take to nursery!).

They were both simple Victoria Sponge cakes (eggs, vanilla sugar, margarine all the same weight then about 1oz extra SR Flour) with buttercream and lemon curd filling.

On the first, smaller one I used fondant icing to cover the cake and make the digger shape – there’s a great ‘how to draw a digger’ pattern on the JCB website, which I found really useful for the design.

The large cake was for his party – we invited 35 kids so it needed to be a big one! Covered with fondant icing, then borrowed a couple of diggers from his toy box (washed thoroughly just in case he’d been digging outside in the mud!) I stuck them in place with icing and crushed some chocolate for the ‘real digging effect’. I mixed fondant icing with yellow food colouring for the sign and surrounded it with little construction site signs. He loved it!

I made this very cute construction cake for my son’s third birthday party recently. I baked a sheet cake and frosted it with homemade chocolate frosting. I used crumbled chocolate sandwich cookies for dirt and rocks, pretzel sticks for logs, and green frosting for grass. I set two die-cast construction vehicles on top. These sort of unique birthday cakes are easy and very cute!

This construction cake is an 8-inch round cake (chocolate and vanilla) with canolli filling iced in buttercream. This boy loved construction toys and it has his favorites topping the cake. His name is made from sugar cookies attached with more buttercream.,

I made this full sheet construction cake and 6″ “smash” cake for a friend of my husbands. It was for a little boy’s first birthday. The theme was a construction site.

His dad sent me a photo of the birthday boy all dressed up in his construction costume so I added him to the construction site as the foreman.

I made “sand pile” and a “top soil pile” in the back corners using the mini wonder mold pan for the mounds. I iced them with butter cream and added crushed vanilla wafers for sand and crushed Oreo cookies (cream and all in the food processor) for topsoil.

I used plastic trucks to decorate. The long truck is carrying logs (Pepperidge Farm Pirouette cookies). In the far corner is a dump truck with some of the “top soil” in the back as well as a front loader that is scooping up the topsoil. The “foreman” is directing the work!

In the front corners are jellybean rocks. The orange cones are candles and there are plastic construction signs along the front of the cake board. The border of the construction cake is iced in diagonal caution bands.

The family that got these cakes moved to NY and called me a year later asking me to do their son’s 2nd year birthday cake because they liked the first one so well! A bit of a long delivery I’d say from VA!

Construction Cake

I needed to make a construction cake for a friend of mine. I started out with a sheet cake and used some of the cake that I cut off the top to make it level and to make a raised area on the upper left corner for a hill.

Construction Cake

For the icing for the construction cake I tinted butter cream frosting brown and iced the cake and hill. I used some blue frosting to make a small pond and covered that in blue gel to make it look more water-like. I took some black frosting and made a small blacktop road on the construction cake.

The rocks surrounding the cake and scattered on top are chocolate rocks I found in a candy store. The “sand” was just some crushed snicker doodle cookies. The blocks were candy Legos, also found in a candy store. I bought a small plastic construction set and placed the truck, some signs, and men on the cake as well.

The border of the cake was just a thick string of frosting with some of the candy rocks put on it. The construction cake was not difficult at all. It doesn’t take long to decorate the construction cake and was a lot of fun to make!

This chocolate construction cake was covered in yellow Butter cream icing. I sprayed the stripes with an airbrush. I used Oreo crumbs for dirt and chocolate candy rocks. The plastic toys were bought from Toys R Us. It is a 12 inch base with an 8 inch top. The little boy loved his construction cake!!!

This construction cake was so fun to make, I even had my husband suggesting where all the little construction vehicles would go!

I used yellow and black gel for the construction zone stripes and cookie crumbs for the sand/dirt. You can add beige/white/brown M&M’s for rock piles etc.

Very fun cake to make! Enjoyed by all!

Construction Cake

I started with a large sheet pan and I used 2 cake mixes total to fill the pan.

When the cake was cool I put it on a board covered in “construction” wrapping paper. (I used this same wrapping paper to make street signs for the cake — I cut out stop signs, yield signs, caution signs etc. and glued them to white cardstock. Then I cut these out and mounted the signs onto Popsicle craft sticks.)

Construction Cake

I iced the cake with buttercream frosting, tinted a slightly beige color. I did my lettering and borders using yellow and black icing (I use Wilton paste colors). The lettering was yellow with a thinner black line on top — this really made the letters “pop”!

Construction Cake

I put real construction toy trucks on top of the cake, as if they were part of a construction site. The signs were placed around the trucks, then I added my “dirt” — I mixed equal parts Oreos and Vanilla Wafer in the food processor and blended them until they looked like real dirt.

On my computer I created “caution” tape and “birthday zone” signs. Party favor bags were placed in a large Tonka dump truck on the table, and I used yellow and black plates and napkins.

This was a chocolate cake for my sons 2nd birthday. He loves cars and trucks! I went to a party store and purchased mini trucks and cars and arranged them on the top of cake. I used brown sugar to make a “dirt pile” and trimmed with M&Ms his other favorite thing. He really loved this cake.

Construction Cake

For my son’s fourth birthday he wanted a construction party. I searched the internet for cake ideas and finally put this one together using many different cake ideas I found.

I used a plain yellow cake and iced it with chocolate frosting. I dug a small hole out and filled it with M&M boulders. I used candy corn as the cones around the hole. Chocolate-covered graham crackers became the road. To make the trees I flattened green gum drops and gave them a pretzel stem. An under-construction house was made out of pretzel rods. Finally I added some cars and road signs. This cake was very easy to make and my son loved it.

Construction Cake

I used a devils food cake mix and a yellow cake mix and made cupcakes out of both mixes. I arranged the cupcakes in a rectangle; one half devils food and the other yellow. I mixed up 3 batches of Wilton ‘s buttercream frosting. I originally had planned to dye the icing brown for dirt but had to save time so I left it cream colored. I spread it on thick enough to cover all the gaps and holes on top of the cupcakes. (Tip: A small dot of icing under each cupcake keeps them from sliding as you ice the cake.) I crushed up graham crackers for the roadway and chocolate graham crackers for the gravel. I used the candy letters you can find at the grocery store for the writing and added a construction set I bought at Big Lots. Everyone loved this cake and it is one of those cake ideas that is so easy to just pull apart and serve.
