In a large bowl, using a hand mixer (or using a stand mixer and the paddle attachment), beat the butter and sugar until fluffy.
Turn the dough out onto a lightly floured surface (or if baking in blocks, a piece of parchment paper) and roll to approximately ¼" thickness. OR cut the dough with cookie cutters (if using) and place on a parchment-lined baking sheet. If baking in blocks, use a pizza cutter to even the edges of the dough, and transfer the cut block of cookie (parchment paper and all) to a baking sheet.
Bake in a preheated oven for 15-17 minutes or until you achieve your desired color or doneness.
