Preheat oven according to cookie dough package or recipe.
Firmly press cookie dough into 9-inch cake pan.
Using the prepared cookie dough, my cookie cake took approximately 12 minutes until it was completely perfect - browned but still soft and chewy.
Wait until cooled completely and then using a piping bag and tip (I used a Wilton #18 tip) and alternate frosting colors to replicate the look of those big cookie companies.
Cut with a pizza cutter, serve, and enjoy!
