Robot Birthday Cake

Another day another birthday around here, yes, when it rains it pours birthday confetti! My baby boy recently turned six, SIX people!!! gah!! What happened to my baby boy? I swore I told that kid he wasn’t allowed to grow any older than 4 and here is already 6 and still not listening! Birthdays are bittersweet aren’t they?

For this birthday boy I decided to make a Robot Cake, because it just screamed ‘little boy’ and I was sure he’d love it. I had seen the idea pinned onto pinterest of course, but it went to a photo gallery. No worries, just a photo of the cake was easy enough to work with, it was actually very simple to assemble!

Robot Cake - Mom vs the Boys

Robot Cake

You’ll Need

Box mix in any flavour you like (I used rainbow chip)
Buttercream icing any colour (I used orange)
small donuts (Chocolate or powdered work well)
2 oreo cookies
m&m’s (2 brown for the eyes, red for the mouth, any colour combo for the rest)
6 mike and ike style candy

To Assemble

Bake the cake according to directions on the box in a 9 x 13 pan. I had some extra cupcakes on hand, but you can also use muffins or put some of the cake mix into cupcake liners and the rest into the pan and bake both. Once cooled, cut the cake to shape, large rectangle on the bottom and a smaller one on top for the head. Cover both evenly with buttercream icing. I was planning on making a traditional grey robot, but I could only fine white donuts and with the tin foil behind the cake, I decided that the robot needed a punch of colour and opted for a bright orange.

For the face, unwrap the lollipop and place the stick into the top of the head. For the eyes, separate the Oreo cookies. You can secure the brown m&m’s with a dap of white icing or he’s a little trick. My cookies left the white inside icing a little dirty, so I took a knife and scrapped a thin layer off of the oreo icing. Then I just rolled that into a ball and used it to secure the pupil. Worked like a charm. I used 8 red m&m to read a smiling mouth.

For the feet, add the mike and ike candies to the side of the cupcakes like laces.


The belly is the control panel, start by creating your child’s new age like you would see it digitally. I used hard black candy that tasted like black licorice so it would stand out well against the colour. I was a little worried about choking so the boys didn’t eat these, but gumballs are about the same size and would work well, or just go ahead and use m&m’s for the whole thing. Once you have the basic shape of the number, fill in the rest to create a square.

Robot Cake

For legs and arms, use a dab of icing to the bottom of a donut and just stick them in a row. Place the feet at the bottom of the legs, and cut one donut in half to create hands. For the neck just slip a donut between the head and body.
