Hot Wheels Birthday Cake

By · Print This Post Print This Post

It was such a busy summer that I never got around to sharing this birthday cake idea with you. My son loves Hot Wheels! His love of cars started at a very early age, and by the time he was three years old could tell me which cars were Hot Wheels as opposed to any other brand of toy car. I created a Hot Wheels monster truck cake for him when he turned 5, so I wasn’t expecting to make another Hot Wheels cake for him this year. But, two days before his birthday, he insisted on a Hot Wheels cake. And not just a Hot Wheels cake, but a Hot Wheels race track cake. Huh? Has he been watching Ace of Cakes when I wasn’t around? I loved the creative challenge, but with only two days to figure it out, I figured he’d have to accept whatever I could come up with.

I started going through his Hot Wheels tracks for ideas. I found a fun little track that I thought would be fun to incorporate with it. But, I couldn’t remove all the track pieces from the base and support structure. As I discussed the idea with my husband, he suggested that we just use the regular flexible Hot Wheels track pieces to make our own race track. Well, they seemed a little big for it, but he convinced me he could make a support structure for it. OK. But to be a Hot Wheels track it has to have a loop, right? And wouldn’t it be fun if it went through a tunnel in the cake? So, that’s how the thoughts flowed to come up with this idea. Crazy, I know. But the kids loved it!

I didn’t get pictures of the building process. I was too busy trying to figure out what to do to stop and take a picture. And, I’m really sorry I never got a video of it working. We had to enlarge the tunnel a little, and find the right, low-profile car to make it through the tunnel. The kids at the party all enjoyed giving it a try before we cut the cake. It worked most of the time, though the car got stuck in the frosting a couple times.

More specifics:

I baked two round 9″ cakes. I used Betty Crocker Gluten-Free Cake Mixes and followed the baking directions.

I made Wilton’s recipe for Chocolate Buttercream Icing, and used Hershey’s Special Dark Cocoa to make it almost black (and deliciously chocolate :P).

For the bottom layer cake, I cut a path for the tunnel 3/4 of the way through the middle. (At this point, it looks almost like the letter U.) Then, I frosted the top and inside the tunnel.

For the top layer cake, I cut out another path for the tunnel. Then, I placed the cake on top of the bottom layer. I had to make some adjustments for the tunnel, by cutting a little more here and there so that the cake becomes like a ramp down the middle. After testing it with the track, I frosted the top, sides and inside the tunnel.

For the side of the cake, I tried to keep the decoration simple. I used a plastic chop stick to make indentions along the side of the frosted cake to resemble tire tread.

For the flames: I used simple icing made with powdered sugar and water. (I start with 1 cup powdered sugar and 1 Tbsp water and adjust as necessary.) Then I separated it into three small bowls and used food dye to create red, orange and yellow frosting. I used Wilton’s small round #3 decorating tip to outline the flames. Then, filled in with the different colors as shown in the picture. I used a small knife to spread the frosting to fill in the flames.

For the support of the track, my husband used a yard stick and a dowel rod secured with a nail. The track and clamp are all Hot Wheels pieces I drug out of the toy bin at home. The track had to be high enough to make the loop successfully. It also needed a little support in the middle of the track, so we used a straw taped to the underside of the track and top of the yard stick.

Wow! What a super fun idea! I love that it’s an interactive cake. Playing with your food is good. πŸ™‚


Wow, what fun! Your cake turned out great!


Thanks, Deanna. We did have fun playing with it!


Thanks, Andrea. It’s not exactly the wonderful 3-D cakes you and your husband design, but we had fun with it.


How creative! My boys are too old for this kind of cake, but they would have loved it when they were younger.


Vroom. Vroom. Mama has set the bar pretty high for the next birthday. That is the coolest cake.


Adorable, Heather! I was going to comment that you and Heidi needed to get together and then saw your link to one of her equally awesome cakes. Very, very cool cake! I enjoyed making fun cakes for Son when he was growing up. That was before gluten free and my most ambitious cake was a tank. It’s still talked about, so I’m sure this cake will live on, too. An, who knows … you might have to make a Hot Wheels cake every year until the phase passses. I’m wondering what your next variation might be …



Holy Cow Heather, that is so C.O.O.L.!!!! What a fantastic idea you and your hubby came up with, I NEVER would have thought of something like that (I’m almost speechless…really). Thanks for the link love and for the wonderful ideas (Sam just so happens to want a Star Wars Lego cake for his birthday next month).

I’m sure the car getting stuck in the icing was cool for the kids though, just like a car wreak. πŸ˜€



You’re right Heidi, we just wiped the frosting off the car and tried it again. The kids loved it!


Shirley, you may be right. Maybe I should start thinking about a Hot Wheels cake for next year. Maybe I’ll make the cake a tire standing up and have the car jump through the middle. πŸ˜› If I asked my son for ideas, who knows what it could be.


You’re sweet, Wendy. I’m sure my son will challenge me with another idea next year. Hopefully, he’ll give me a little more time.


What an awesome cake! You are a great mom!


W~O~W, that is totally amazing. At first, I did not notice that the track was useable. AWESOME. Now that is what I’m talking about. I wonder if hot wheels cake would go well with a Karate birthday? LOL


Wow!!! I’m not only impressed, I’m a bit jealous. I can make a cake that tastes good by my decorating skills are seriously lacking. Great job, very creative.


that is totally awesome! go you for getting so inventive, and even better that it came out so beautifully! what a fun adventure.


Thanks, Brian. But there really wasn’t much to the decorating, which was a nice change from past cakes that needed a bunch of different colors and decorating tips. Plus, I left the track building to my husband. πŸ™‚


Lisa – Karate, huh? Well, the kids probably wouldn’t care either way. So what are you doing for a karate cake? A broken board sticking out of the cake? lol.


Lea, you overwhelm me with your praise. Thank you.


Wow, that is one amazing cake! And what fun. Lucky kids!

Thanks so much for your comment on my blog, and for reading! Glad you liked the brownies. πŸ™‚


Holy Smokes, that is incredible! Way to go girl πŸ™‚


Thanks, Laura. My children appreciate your encouragement. πŸ˜‰


Heather……I can’t believe this is the first time I have seen this picture….where have I been? This is spectacular. Hurry up and get stationed in Omaha so we can start having these parties together while the kids are still little!!!!!!!!!! Phenomenal idea….wish we could have been there to try it out!


Kerri – I know I was slow to post the photos. I haven’t seen any pictures of the Lemonade Stand party either…hint, hint. You know we would all love to be closer to share these fun moments with you and the family.


How awesome! Any boy would LOVE to have this cake at his birthday! Great job –


What a great idea!! I just might have to try this for my grandsons. They are big CARS fans and I think I could make it work with that. Thanks for the idea πŸ™‚


Thanks, Kathy. Hope it works out for you.


Whoa… that’s amazing! Charlene emailed me about this and I’m totally blown away!


Thanks, Rachel. It was pretty easy to decorate. Just a needed a little creativity and the engineering help from my husband. Not to mention all the Hot Wheels supplies from my son’s stash. πŸ™‚
