The 70° F cookie dough baked in a 350° oven had a medium spread and are the cookies in the photos in this post.

The 73° F cookie dough baked in a 350° oven had the most spread, however it was just slighter than the 70° cookie dough.

Optional decorating ideas
For a pretty, sparkly look, roll the balls of dough in granulated sugar before baking.
For a salty sweet flavor, instead of rolling in sugar, sprinkle the cookies with sea salt after baking. If sprinkling with sea salt, reduce the salt in the cookie to ½ teaspoon.
Press a pecan half or chopped pecans onto the top of the unbaked ball of dough before baking.
For these cookies, I rolled the dough into a ball, pressed chopped pecans into the top half of the ball, gave it another roll between my palms, rolled it in sugar, then pressed a pecan half into the top.
