Pre-heat oven to 350 degrees.
In a medium bowl, combine cake mix, eggs*, coconut oil and yogurt. Fold in your mix-ins.
Place cookie batter by heaping tablespoons (I used a cookie scoop) on a baking mat (or non-stick cookie sheet) about 2 inches apart and bake for 8-10 minutes - depending on the size of your cookies.
Let cool on cooling rack (if you can!). Store in air-tight container.
