2 cups sugar
2 cups butter, softened
1 tablespoon baking powder
1 teaspoon baking soda
1 teaspoon vanilla
1 cup sweetened flaked coconut
Combine all ingredients except coconut in large bowl. Beat at low speed, scraping bowl often, until well mixed (5 to 8 minutes). Stir in coconut by hand.
Divide dough in half; shape each half into 12x2-inch log. Wrap each log in plastic food wrap; refrigerate until firm (at least 2 hours).
Heat oven to 350°F. Cut logs into 1/4-inch slices. Place 2 inches apart onto ungreased cookie sheets. Bake for 10 to 14 minutes or until edges are lightly browned. Let stand 1 minute; remove from cookie sheets.
I had to improvise a bit as my slices didn't come out well - still taste good, just look like sugar cookies *grin*
