How to Create A Motocross Birthday Cake:

Bake two 9 x 13-inch chocolate cakes and two loaf pan cakes. I used three King Arthur cake mixes. We chose chocolate cake, but any flavor cake mix would taste great.

A few cakes in pans and a tube of bavarian cream.

While the cakes are cooling prepare your frosting. Use your favorite dairy free chocolate frosting recipe. Set the frosting aside.

After the cakes have cooled, remove them from the pans. Add frosting to a piping bag and pipe around the outside of one 9 x 13 inch cake. Then snip a corner of the Bavarian cream pastry bag and pipe the inside of the cake.

Snipping the corner makes it a large hole so the Bavarian cream can come out faster

Important note: After filling in the bottom cake layer you’ll have about 1 cup left over. You can refrigerate leftovers for a future baking adventure.

Next, place the second 9 x 13-inch cake directly on top of the bottom cake.

Then construct two ramps out of the two loaf pans.

Cake ramps on a cake base to make a dirt bike track cake.

Constructing the ramps was trial and error. We used a knife to shave off the ramps. Our ramp cuts were messy and that’s fine. As you ice over the ramps and fill them with crushed gluten free Oreos it will look perfect.

Keep in mind we didn’t use all of the loaf cakes so you could construct a third ramp if you wanted.

Now ice the cake on the top and all sides with an offset spatula like this one. After the cake is iced you are ready to create the race track. Keep in mind all the edible decorations are gluten and dairy free.

To decorate the cake first, crush the Gluten Free Oreo Cookies in a Ziploc bag. You want the crumbs to be very fine without any big chunks. Then place layers of crumbs where the motocross trail will go.

Next place the trees and bushes alongside the trail.

Lastly use the candy rocks for borders and place the race flags.

Place the motocross figurine last. As in…right before singing Happy Birthday.

Have fun creating your own one-of-a-kind motocross birthday cake! 

The lumpier the better. Surprisingly the more imperfect the cake, the more your special someone will love it!


This Motocross cake is best enjoyed the day that you assemble and make it. If you have leftover cake, you can remove the decorations and store in airtight container in teh fridge for up to 2 days. Between the frosting and the bavarian cream filling, you really need to refrigerate the cake.
