• Preheat the oven to 375° then line a baking sheet with parchment paper. Add the dry cake mix, room temp butter, eggs and oil to a medium size mixing bowl. Use a hand mixer to combine.
• Blend in green food color gel until it reaches your preferred shade of green then refrigerate the dough 15 minutes for easier handling. 
• Combine the powdered sugar and cornstarch in a small bowl.
• Roll the dough into about 1” balls (use a scooper if you have one) then coat the balls in the powdered sugar mixture.
• Place the cookie balls on a parchment paper lined baking sheet (do not flatten the balls) and bake 8-10 minutes or until the cookies are lightly brown on the bottom.
• Remove from the oven and leave the cookies on the baking sheet for 2 minutes then transfer to a wire rack.

Decorating the Grinch Cookies:

• In a small bowl blend the “glue” ingredients then add to a sandwich baggie. Clip a small corner of the baggie then pipe a dot of glue onto the top of the cookie. Press a red heart in place then allow to set couple of minutes to dry.
