Mickey Mouse Birthday Cake:
*Mickey Mouse Cake: Bake one 9" round cake and two 6" round cakes. Position the cakes so the bigger cake is the face, and two smaller cakes are the ears of Mickey.
Frost the face with white frosting. Print a picture of Mickey off the internet. Use that image as a guide to outline the face of Mickey with a toothpick. Use cake piping bags to add facial features in color. Frost the ears with chocolate frosting.
Mickey Mouse Party Food Ideas:
*PB&J Sandwiches: Use cookie cutters of various shapes (stars, hearts, etc.) to cut the sandwiches.
*Mickey Mouse Sundaes: Use ice cream and melon ball scoops to create Mickey's face.
Put one large scoop of vanilla ice cream (using bigger scoop) for face, and two scoops (using smaller scoop) for ears. Add 1 chocolate chip for nose, 2 chocolate candies for eyes, and push in 2 Oreo cookies for ears.
