As I mentioned before we recently hosted a #disneyside Cars themed Birthday Party for Camden, and since we had the perfect Lighting McQueen jumpsuit for him. I wanted to make his birthday cake the perfect compliment to him so Mater was the obvious choice.
The key to making this is having fun and making the brownies so they have enough time to cool.
Step 1: Make both boxes of brownies in a 9×13 pan making sure you coat the pan so the cake can transfer easily. We used a baking nonstick cooking spray with flour
Step 2: Flip the cake onto a cooling rack and allow to cool before transferring it to a platter. We chose to keep the bottom as the top, but I think I would switch it to give more texture next time.
Step 3: Cut out the sides of Mater. We measured 2 inches on each side.
Step 4: Take one clear straw and cut it into 4 pieces
Step 5: Use the swiss rolls as the rearview mirrors and the straw to attach them
Step 6: We traced out with a knife the shape for Mater’s face, smile and teeth.
Step 7: Mix together confectioners sugar and milk to make a liquid frosting. Tip: Add the milk small bits at a time till you get the best consistency. You don’t want it too thin, or too thick. You also don’t need a whole bunch.
Step 8: I used the whisk and fork to drizzle the face, and teeth on.
Step 9: Once the face and teeth are done add the green eyes and yellow headlight.
Step 10: Add a little cocoa power to the icing to give it a brown color.
Step 11: Put the icing in a plastic baggie and cut a VERY tiny hole on the corner, then pipe out the smile, around the face and the bumper.
Step 12: Cut 2 mini chocolate donuts in half. Use the icing to attach for the nose, two tires on the bottom, and enjoy the other half as a reward.
It’s really quite simple and just as time consuming as making and icing a cake, plus you don’t need to have any specific decorating tools. As long as you have a 9×13 pan and 45 minutes you can make this super fun cake that any Cars fan will love!
