Back to school Bus cookies

I love that my Husband is a grade school teacher, even if it's b/c I get to bake fun goodies for his class! This year I did welcome back cookies. I made them Bus shaped cookies with there name on it. I also gave them a welcome back goodie bag with pencils, erasers, and fun stuff. I never posted this before b/c our camera happen to go to crap the day I made them. So here is a bad picture, but a picture none the less.

What You Need:
1 bag M&M'S Brand Milk Chocolate Candies
1 tube M&M'S Brand MINIS Milk Chocolate Candies
1 18-oz. roll refrigerated sugar cookie dough
2/3 cup flour
2 16-oz. cans vanilla frosting
1 16-oz. can chocolate frosting
Yellow and green food coloring
Baking sheet
Parchment paper
Spatula
2 resealable plastic bags
Microwave-safe bowl

What To Do:
1. Preheat oven to 350 degrees. Line the baking sheet with parchment paper.
2. Knead the sugar cookie dough and flour until smooth. On a lightly floured surface, roll out the dough to a scant 1/4-inch thickness. Using the printable template, cut out the shapes, re-rolling the scraps if necessary. Then, use the spatula to transfer the shapes to the prepared baking sheet.
3. Bake for 12-15 minutes, or until golden brown. Remove from the oven, transfer to a wire rack, and let cool completely.
4. Tint 1/2 cup of the vanilla frosting green, place it into a resealable plastic bag, snip off a small corner, and set aside. Tint the remaining vanilla frosting yellow, and place it in a microwave-safe bowl. Heat for about 10-20 seconds, stirring every 5 seconds until the it's consistency of slightly whipped cream.
5. Spoon the heated frosting over the cookies one at a time—completely covering each one. You may have to scrape up excess frosting and reheat it to cover all the cookies. Let the frosting dry for about 30 minutes, then carefully remove the cookies from the rack and scrape any excess frosting from the edges.
6. Spoon the chocolate frosting into one of the resealable plastic bags. Snip a small hole from the corner and pipe frosting for decoration. Then, using the photo as a guide, add M&M'S Brand Milk Chocolate Candies. Finish by snipping a small hole from a corner of the plastic bag with the green frosting and piping on the names.
