Preheat oven to 375 degree F. In a large mixing bowl beat butter and egg with an electric mixer on medium to high speed for 30 seconds. Gradually beat in cake mix until combined; stir in cornmeal and lemon peel, if necessary knead dough to blend.
Using 1 tablespoon of dough for each cookie, roll into 1-inch balls. Roll in sugar. Place 2 inches apart on ungreased cookie sheets.
Bake for 9 to 10 minutes or until bottoms are lightly browned. Let cool on cookie sheet for 1 minute. Transfer to wire rack. Cool completely. Makes about 3-1/2 dozen cookies.
