Butter Cookies From Scratch
To make balls, simply roll one teaspoon of dough into 1 1/4-inch balls. Roll in coarse sugar or finely chopped nuts. Bake, switching position of sheets halfway through baking, until bottoms are browned, about 15 minutes total.
To garnish cookies with chocolate, melt 3 1/2 oz chocolate and cool slightly. Transfer to a heavy-duty sealable plastic bag and snip a 1/16-inch opening in 1 corner. Pipe chocolate evenly back and forth over cookies. Let chocolate set before storing cookies.
Cookies keep, layered between sheets of wax paper or parchment, in an airtight container at room temperature 1 week.
