The yummiest kind of motorbike for ripping up single track is made of modeling chocolate. This motorcycle cake tutorial is for cake decorators who find themselves challenged by designs that involve two-wheel vehicles, i.e. bicycles, dirt bikes, scooters etc. Because the problem with two-wheelers is that they don’t translate smoothly into the edible form. Consider a standing moped cake decoration made from gumpaste for instance and all the effort and infrastructure that would involve. Or imagine carving a motorcycle shape out of cake…the nightmare frosting job that would ensue. No thank you! Here I will sculpt a mogul (i.e. a mound) of cake, build a motorbike in parts, then place them on the cake to give the impression of a completely intact standing vehicle.
Edible Materials Needed
– ¼ sheet cake
– 4” diameter round chocolate cake, 2” thick
– 5 cups chocolate buttercream
– 1/2 cup vanilla buttercream
– 1/3 batch of modeling chocolate – some tinted light blue
– 2 cups chocolate glaze
– 1/3 cup chocolate chips, ground in a food processor to look like dirt
– White piping chocolate for the inscription
– Cocoa powder for dusting
– quarter sheet pan
– 4” round cake pan (or 4” round cutter)
– 4 1/2” round cutter
– Felt tip marker
– Parchment paper
– Craft utility knife
– Gumpaste/fondant modeling tools
– Small round and square microcutters
1. Cut a 4” wide cylinder of cake in half to form two wheels (alternatively, cut 4” circles out of a sheet of cake using a 4” cutter). Cover them in plastic wrap tightly, pressing to round the edges slightly. Freeze solid.
2. Once frozen, dip the topside of the wheels upside down in chocolate glaze. Allow the wheels to set in the refrigerator for at least 20 minutes before handling again.
3. Saw diagonally through a 1/4 sheet cake the long way, taking the edge off the 90º front ledge. Rotate the wedge 180° then reattach it to the cake, creating a slanted surface like a mountain face on which to display the motorbike. Alternatively, during the filling stage, assemble a 1/4 cake in the shape of a mound.
4. Plunge a 4 1/2” round cutter into the face of the mogul to mark the position of the wheels. Hollow out each spot a little to create grooves for wheels to nest in. Angle the grooves slightly so that the wheels will both tilt inwards.
7. Draw a motorbike onto the parchment paper using the wheels and the outline of the cake to frame its size. Reference images on the internet to get a sense of how a dirt bike looks.
8. Tape the drawing to the flat underside of a clean sheet pan.
10. Shape the components of the bike out of modeling chocolate, making certain aspects bulge more than others to add depth and dimension. Create disjointed parts that fit together like a puzzle but are not attached. That way, they can be pivoted and rearranged when it comes time to place them on the cake.
12. Allow the motorbike parts to rest, untouched and uncovered at a cool room temperature for at least two hours before handling them again.
14. With a small offset spatula, roughly add chocolate buttercream underneath the wheels to secure them and create the impression that loose dirt is kicking up behind.
17. Dust the top of the cake lightly with cocoa powder for one final touch of dirt.
