Preheat your oven to 350 degrees F
In a large bowl or stand mixer, pour in cake mix, one large egg and the full tub of cool whip and beat together until light and fluffy.
Use a one inch cookie scoop to scoop out the cookie dough.
Drop each scoop of cookie dough directly into the powdered sugar (the cool whip dough is very sticky so you don't want to hold the uncoated dough directly in your hand) and lightly roll them around until covered then place them onto a cookie sheet lined with parchment paper about ½ inch apart.
Bake for 10-12 minutes until set, then remove them from the oven and allow them to cool on the pan.
While the cookies are baking add the second tub of cool whip to a bowl along with the strawberry gelatin powder and use a spatula to blend the two together. This will flavor the cool whip and color it light pink. (Feel free to use more or less to your taste)
Frost each cooled cookie with the strawberry cool whip and sprinkle on diced strawberries on top.
