One night, while everyone is asleep, the white cat Lulu and the black cat Lala discover that the moon has disappeared. They decide to bake a moon cookie to light up the now dark sky. As they gather ingredients, they explore various stars: the slippery butter star, the twin-like sugar and salt stars that look alike but taste different, the precarious egg star that must be handled carefully, the flour star where powdery snow falls all day, and the vanilla star, where oil droplets float like balloons. Lulu and Lala gather all the ingredients and, with the help of a shooting star, complete the sweet and delicious moon cookie with a bursting flame. This charming picture book uses familiar and relatable elements to spark curiosity and imagination in young readers.
