Line a cookie sheet with parchment paper and preheat your oven to 350 degrees.

Remove the packet of cinnamon sugar from the Betty Crocker® Snickerdoodles Cookie Mix bag and pour into a separate small bowl.

In a large mixing bowl, beat together the egg, butter, water and cocoa powder until thoroughly combined.

Add in the Betty Crocker® Snickerdoodles cookie mix and beat at low speed for about 30 seconds,  until completely mixed.

Roll dough into teaspoon-sized balls and drop into the cinnamon mixture, rolling around to evenly coat.

Place on parchment paper lined cookie sheet about two inches apart and bake for 9 minutes.

Remove from the oven and allow to cool on a baking rack.

If you do not have a baking rack, you can simply slide the parchment paper off the cookie sheet - with the cookies still on it - directly onto your counter and allow them to cool there.
