Simple Chocolate Crinkle Cookies

"- These cookies are best served fresh out of the oven; however, they will keep in an airtight container for 2 days. - Doctor up these cookies even more by playing with different extracts and add ins. I think a little orange zest would be a great addition, or try adding in a little mint extract for easy Chocolate Peppermint Crinkles. - This base recipe does work well with other box flavor varieties, I have tried it with lemon cake mix which resulted in delicious, chewy lemon cookies...."
