Preheat oven to 170 °Celsius. Grease and flour the car cake mold.

In a medium sized bowl, beat butter and sugar till soft and creamy for about 2 minutes. Add eggs, one at a time, beating well after each addition.

In a separate bowl, sift flour, baking powder, and salt. Fold in the sifted ingredients into the creamed mixture alternately with milk, starting and ending with flour.

Remove the cake from the oven and let it rest in the pan for 5 minutes before turning out onto a wire rack. The cake should be placed on the wire rack, facing up. Cool the cake completely before icing and decorating.

Since the cake was baked in a shaped pan, there was no need for any sculpting work.

Start off with the body of the car and cover it in red butter icing. Smooth the butter icing on the body of the cake, leaving out the car windshield, windows, and the wheels.

Next, cover the windshields and side windows. I used untinted butter icing for these. The butter icing had a natural ivory hue to it because of the butter and so I left the color as such.

For the wheels, use black butter icing and dark gray (mix some white food color into the black icing) icing.

Once the wheels are done, add the lights, both at the front and back of the car and bumpers. Transform the lights at the front of the car into the car’s eyes by piping a tiny dot of black buttercream in the center. To shape the lights, simply take some butter icing and shape them into oval balls. Flatten them lightly (the butter icing is stiff so it is possible to shape it by hand) and attached to the car. And finally, using black buttercream, pipe a smiling mouth for the car, borders for the windshield and windows, and a set of wipers.

To finish decorating the car shaped cake, outline the windows with black buttercream using Wilton tip #3.

As for the wordings, roll out some blue tinted fondant and cut out the letters with the alphabet cutters. Simply place the cut letters on the cake. They will stick to the butter icing without the need for any special fondant glue.

Once the car is done, pipe some green colored buttercream icing for the grass on the cake board, all around the car.
