Frosting,storebought or homemade, and colored with food coloring, if desired
Sprinkles,jimmies, nonpareils, etc.
Preheat your oven with 375°F, and line a 13x18 inch pan with parchment paper (or grease it, but the parchment makes it easier to lift out the entire cookie at once).
In a large bowl sift together flour, salt, and baking soda or add to the bowl and stir with a whisk to combine.
Using a stand mixer or hand mixer, in a large bowl cream butter and sugar until fluffy.
Add eggs, one at a time, mixing well after each egg.
Mix in the vanilla.
Reduce mixer speed to low and slowly qdd the flour mixture to wet mixture and mix just until combined.
Spread on the prepared baking sheet. The dough will be sticky. I find spraying oil or cooking spray on my hands and/or a spatula makes it easier to press into the pan all the way to the edges and corners.
Bake at 375° for 10-15 min, until light golden brown or until a toothpick comes out clean (they won't look done, so do the toothpick test).
Cool completely, remove from the pan if desired, frost and decorate.
Cut into small squares approximates 1 1/2 inches x 1 1/2 inches. Store in an airtight container at room temperature or freeze for up to two months.
Note: Nutritional information is approximate, and will depending on the type and amount of frosting and decorations used.
