1 package yellow cake mix
1/2 cup shortening
1/3 cup butter or margarine -- softened
1 tsp vanilla, almond extract or lemon extract
Green sugar sprinkles
Heat oven to 375º.
Beat half of the dry cake mix with the shortening, butter, vanilla and egg in a large bowl with electric mixer on medium speed until smooth, or mix with spoon. Mix in the remaining cake mix.
Divide dough into 4 equal parts. Roll each part 1/8 inch thick on lightly floured surface. Cut with a Shamrock shaped cookie cutter; sprinkle with sugar. Place 2 inches apart on ungreased cookie sheet. Bake 5 to 7 minutes or until light brown. Cool slightly; remove from cookie sheet to wire rack to cool.
