Peanut Butter Easter Truffle Eggs

1 package (8 ounces) cream cheese, softened
1/2 cup butter, softened
1 jar (17.3 ounces) creamy peanut butter
1 teaspoon vanilla extract
1 package (2 pounds) confectioners' sugar

6 cups (36 ounces) semisweet chocolate chips
1/3 cup shortening

Directions
In a large bowl, beat cream cheese, butter, peanut butter and vanilla until smooth. Beat in sugar. Form rounded tablespoonfuls into egg shapes. Place on waxed paper-lined baking sheets. Chill for 30 minutes.
In a microwave-safe bowl or heavy saucepan, melt chocolate chips and shortening: stir until smooth. Dip eggs until coated; place on waxed paper to harden.
For more decorative eggs, place about 1/4 cup melted chocolate in a small plastic bag. Cut a hole in the corner of the bag; pipe chocolate over tops of eggs. Store in the refrigerator. Yield: about 5-1/2 dozen.
