Preheat oven to 350F. Mix cake ingredients according to box instructions. Fill jelly roll pan with batter; smooth and even it out with a spatula.

Bake for 25-30 minutes, or until a toothpick inserted in middle comes out clean. Let cake cool.

Take your star mold and grease it lightly. Insert it into one corner of the cake and press down, creating a star shape. Remove the mold and carefully lift out the star-shaped cake.

Repeat this process using as much of the cake as possible. We got 9 stars from an 11×17 pan. The amount of stars you yield will depend on the size of your mold.
