This construction birthday cake is cute on the outside and tastes awesome on the inside — that’s because I used bakery-grade vanilla cake recipe and chocolate buttercream frosting recipe from my favorite professional bakers, Cakegirls. Be sure to see my instructions below on how to turn the vanilla cake tan like dirt without using food coloring.

I promised myself years ago that I would no longer puss out by buying cakes at the bakery for my kids. Nope, no more bakery birthday cakes for me. I swear I going to make my kid’s birthday cakes all by hand no matter if they’re lopsided or whatever and you know what? Handmade cakes actually turn out pretty great.

Liam’s construction birthday cake was a big hit, and it was a no-stress cake to make which gave me more time to make DIY construction party decorations like my printable construction cone happy birthday banner, DIY construction birthday t-shirt, and personalized construction hats.

Aren’t these teeny construction cake toppers cute? Using plastic diggers and dump trucks is pretty much a universal construction birthday party cake decoration — topping cakes with these little diggers are easy, quick and such a hit with the kids.

How to make an easy construction birthday party cake:

Step 1: Bake your construction cake layers

First, bake your construction cakes. I used the Cakegirls vanilla cake recipe with one substitution: instead of regular white sugar, I used organic sucanat which is a whole cane sugar that my friend Heather at YumUniverse introduced me to. It’s natural sugar cane that’s minimally processed. Taste-wise it’s a bit richer, kind of has a molasses bent to it. Color-wise, my vanilla cakes turn out to tan (because sucanat is brown colored) which was perfect for the “dirt” cake when it was cut.

I made the construction cakes a couple days in advance, wrapped them in two layers of plastic wrap and tucked them into the freezer which made things a whole lot less stressful. Also, it’s true that it’s way easier to frost a frozen construction cake.

Step 2: Make chocolate buttercream icing and put layers together.

Now make the Cakegirls chocolate buttercream icing. This stuff tastes amazing, folks. Richer and less sugary than regular icing. The kids at our party went gaga over it! I’m talking about licking plates. And the adults liked it too, including one party guest who doesn’t even like cake. (I know, I know, who doesn’t like cake??)

I found a tip online to put strips of wax paper underneath the cake before icing it and it really does help keep things less messy.

Step 3: Break up Oreos into edible dirt for the construction site

OK, time to prep the Oreos. I put my dad on this job, scraping off the white cream filling from the cookies.

Blend in a food processor or in a plastic bag with a rolling pin. Sprinkle between the layers…

Until it’s all covered.

Stack and repeat. I made Liam’s cake three levels high.

The chocolate buttercream recipe makes the perfect amount for a three-layer cake – with just enough left over to sample. See how that wax paper helped keep it all neat? You can remove the strips now.

Step 4: Add Raisinets boulders to the construction case base

I added Raisinets around the bottom edge. I think it looks cute, and it covers up icing mistakes.

The cake inside is still frozen which kind of helped me smooth the sides. And I left the top icing looking like a construction site.

Step 5: Add plastic construction diggers, Oreos dirt, and Raisinets boulders

This is the fun part. Sprinkle on more dirt on top, some Raisinet boulders, and the bright yellow plastic diggers and dump trucks construction cake toppers.

Did you double the cake recipe and frosting recipe to make this cake? Their recipe says it makes a 2 layer cake but yours has 3 layers. Thanks!

Hi Missy! Great question. I personally prefer a three layer cake. I think it looks fancy. You could definitely get away with two but the three is extra nice. I like to spread the baking out over a couple weeks to reduce stress the week of the party. A week or two ahead of time, I bake one recipe of the cake (so two layers) then let it cool completely, cover each layer with layers of plastic wrap and put inside one freezer bag for each layer, then freeze. Then a day or two later, I bake two more layers. So yes, you'll have one extra layer left over for a future cake or cake pops or whatever. Like, I made a mermaid cake for my daughter (https://www.merrimentdesign.com/mermaid-cake.php) last fall and then I just used the leftover round to make cake pops / petite fours for Valentine's Day (https://www.merrimentdesign.com/mini-heart-cakes-valentines-desserts.php). Have a great party!

I too would like to know about how long it takes for the cake to thaw? Using your same process on my son's birthday cake for tomorrow!

Hi Beth! I usually do it overnight. So a day before the party I get it out of the freezer and ice it while it's frozen and add the raisins around the bottom. Then I put it in the fridge overnight and put the dump trucks and crushed oreos in the morning before the party. I hope your son has a great birthday!! ?

I made 4 layers, 9 inch round and froze them. Party is in 2.5 weeks. How long does it take for them to thaw. It would be embarrassing to try cutting in to a frozen cake with guests waiting to try it!

Hi Sheila, they will thaw overnight. What I like to do is ice the cake frozen the day/night before, then put it into the fridge. Then the morning of the party, I add the construction toys, oreo cookies, and raisins. Happy baking!

Thank you for the great idea! I would definitely try this on my grand son's 5th birthday, he seems to be pretty much interested in construction signs whenever he sees them.
