Prepare Cupcakes: Preheat oven to 325°. Prepare angel food cake batter according to package directions. Place paper baking cups into 2 (12-cup) muffin pans. Spoon batter into cups.
Bake at 325° for 22 to 25 minutes or until a wooden pick inserted in center comes out clean. Cool in pans on wire racks 10 minutes. Remove from pans to wire racks, and cool completely (about 30 minutes).
Make a small hole in tops of cupcakes with a knife or end of a wooden spoon. Pipe or spoon about 1 tsp. raspberry jam into centers of cupcakes.
Prepare Frosting: Beat cream cheese and butter at medium speed with an electric mixer until creamy; add lemon juice, beating just until blended. Gradually add powdered sugar, beating at low speed until blended; stir in lemon zest.
Spread Cream Cheese Frosting on tops of cupcakes. Garnish, if desired.
