You can make this with your favorite cupcake recipe. I used a simple box cake mix. I used many chewable candies for the features (eyes, arms, legs, etc.) in order to keep this completely edible.
I also used:
Vanilla Icing - Pre-made
Yellow Food Coloring
Step 1: Creating the Head and Body
To create the shape of the cupcake I need, I place them into the freezer for about 15 minutes.
Slice off the rounded top of the cupcake to make the robot's body. The top will be the bottom. The cupcake will be placed onto a flat cookie. I used a sugar cookie.
First freeze your marshmallows and then slice them into as close of a square shape that you can.
Measure the length between the cookie and the head in order to cut the pretzel stick to the right length. Cut 1 1/2 inch pretzel lengths for the legs.
