Preheat oven to 350°. In a large bowl, cream shortening and sugar until blended. Beat in egg, milk and vanilla. In another bowl, whisk flour, baking powder and salt; gradually beat into creamed mixture. Stir in jelly beans.
Drop dough by tablespoonfuls 1-1/2 in. apart onto greased or parchment-lined baking sheets. Bake 8-10 minutes or until edges are light golden brown. Cool on pans 2 minutes. Remove to wire racks to cool.
Test Kitchen Tip: Hold back a few jelly beans from the dough and press them into the tops of the cookies before baking. That way, you'll have a few colorful spots right on top of each cookie.
