Hershey's Peanut Butter Blossoms

I wanted to make this prior to Thanksgiving, but ran short of time before having to leave town. So, Sunday after Thanksgiving the itch to make these hit...The recipe says it makes 48, but somehow it only managed to make about 40 for me.
Here is the recipe, courtesy of Hershey's.

48 HERSHEY'S KISSES Brand Milk Chocolates
1/2 cup shortening
3/4 cup Peanut Butter
1/3 cup granulated sugar
1/3 cup packed light brown sugar
1 egg
2 tablespoons milk
1 teaspoon vanilla extract
1-1/2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
Granulated sugar

Instructions:
1. Heat oven to 375°F. Remove wrappers from chocolates.
2. Beat shortening and peanut butter in large bowl until well blended. Add 1/3 cup granulated sugar and brown sugar; beat until fluffy. Add egg, milk and vanilla; beat well. Stir together flour, baking soda and salt; gradually beat into peanut butter mixture.
3. Shape dough into 1-inch balls. Roll in granulated sugar; place on ungreased cookie sheet.
4. Bake 8 to 10 minutes or until lightly browned. Immediately press a chocolate into center of each cookie; cookie will crack around edges. Remove from cookie sheet to wire rack. Cool completely.
About 4 dozen cookies.
