In a medium or large mixing bowl, mix together frosting and green food coloring until desired shade of green is reached.
Add frosting to a piping bag with a large star tip or decorative tip of your choice and chill in the refrigerator for 10-15 minutes.
When ready to style your board, start out by piping the outline of a Christmas tree onto the center of a large serving tray or board.
Fill the inside of the tree in with the frosting.
Use the yellow M&Ms to create a star.
Create a tree trunk with the Hershey bar pieces.
Arrange the donuts, cookies, pretzels, graham crackers and any other dippers around the tree on the board. I used peppermints, white chocolate chips and powdered donuts to create a “snowy” ground underneath the tree.
Fill in any gaps with M&M’s, gummy bears, or Christmas candy. Serve and enjoy!
