1Heat oven to 350°F. Grease bottom and sides of 13x9-inch pan with shortening; lightly flour.
2In heavy 2-quart saucepan, heat baking chips and butter over low heat, stirring frequently, just until melted (mixture may appear curdled). Remove from heat; cool. Stir in flour, sugar, vanilla, salt and eggs. Pour into pan.
3Bake 24 to 27 minutes or until toothpick inserted in center comes out clean. Cool completely on wire rack, about 1 hour.
4Spread with frosting; sprinkle with glitter. Flatten some gumdrops with bottom of glass, and cut with star-shaped cutter. Place gumdrop stars and regular gumdrops (jewels) on frosting. For bars, cut into 8 rows by 4 rows.
