Using a medium cookie scoop, portion out the cookie dough onto a parchment paper-lined baking sheet. It's okay to place them very close together, but the portions shouldn't be touching.
Place the baking sheet in the freezer for at least 6 hours, until the dough portions are solid.
Transfer the frozen cookie dough to a Ziploc bag or plastic container, placing pieces of waxed paper in between each layer. Label and store in the freezer for up to three months.
Baking frozen cookie dough:
Remove the frozen cookie dough to parchment paper-lined baking sheets while your oven is heating to the usual baking temperature.
Bake as directed in the cookie recipe, adding an additional 2-3 minutes to the total baking time.
