Preheat the oven to 225 degrees Fahrenheit. Prepare a baking sheet with parchment paper and set aside.
In a stand mixer, add the egg whites. Then add the cream of tartar to the bowl.
Attach the whisk attachment and turn the stand mixer on medium, whipping the mixture until it becomes foamy.
Turn the mixer up to high speed and gradually add the white sugar to the mixture a heaping tablespoonful at a time. Let the meringue mix and become, white, creamy and thick.
Beat this for about 10-15 minutes or until you have achieved stiff peaks. Another way to test the doneness of the meringue is to squish some between your fingers. You should not feel any of the sugar granules when rubbing the meringue between your fingers.
Transfer the meringue to a piping bag fitted with a large round piping tip.
Pipe a large round ball of meringue to act as the base of the snowman.
Make 12 bases across the baking sheet. Then pipe a second round ball on top of the first, slightly smaller. Repeat across the rest of the white bases.
Lastly, create a small round ball on top for the head of the snowman.
Break pieces of pretzel sticks to act as the arms and press into the sides of the middle round of the snowman.
Place 1 M&M in the middle and one in the bottom round of the snowman for its buttons.
Cut a candy corn in half and place in the center of the face for the nose.
Complete all the snowman accessories except the eyes before placing in the oven for 1 hour.
After it bakes for an hour, turn off the oven and let sit it cool in the oven for another hour.
Place the mini chocolate chips on the face as eyes, using any leftover meringue as the glue between the eye and baked meringue cookie.
