Preheat oven to 350 degrees. Line a baking sheet with parchment paper.
In a large mixing bowl, add in the cake mix, eggs, vegetable oil, and vanilla extract. Mix on medium until a dough forms.
Divide the cookies into 5 portions. Each will be a different cookie.
First dough, scoop using a small cookie scoop and roll in sprinkles.
Second dough, scoop using a small cookie scoop. Press a Rolo, peanut butter cup, or junior mint in the center of the cookie and wrap the dough around it. After it's completely covered, roll it into a ball.
Third dough, scoop out. Roll between your palms until smooth. Bake and let cool for 5 minutes. Add a Hershey kiss to the center.
Fourth Dough, stir in chocolate chips, white chips, cinnamon chips, mint chips whatever you prefer. Scoop and bake.
Fifth Dough, add in m&m's. Stir until evenly distributed. Scoop and bake.
Place the scooped dough onto the prepared baking sheet. Place into the oven and bake for 9 minutes. Remove from the oven and let cool 10 minutes before placing on a piece of paper towel to cool.
Wrap up in your homemade cookie boxes and send to your friends and family.
I used about 1/4 - 1/3 cup of the M&M's and chocolate chips in each portion of dough.
