Recipes for kids birthday parties need to please a wide variety of palettes from kids to parents. You can incorporate a favorite food, such as macaroni and cheese, but make it special for the party. You could even try a fried version. Use smaller portions to pass around as appetizers for the adults. Here are some other ideas.
Oftentimes kids birthday parties feature a movie, book, or cartoon character. Incorporate the colors of the movie logo into your meal with food coloring. You can also come up with creative names for old favorites or eat the actual food that is in the book. If you are serving a buffet-style meal, then put the names of each dish on a card, along with the humorous name or fun graphics so guests know what each dish is.
The cake is the centerpiece of any birthday party. You could take a princess cake in a lot of different directions depending on your skill level. You could try a basic sheet cake with candy accents that look like jewels. If you pick up dessert from a bakery you can get unique airbrushing to simulate a crown.
If your birthday party doesn't have a theme, then you can just go with a bright color palette or your kid's favorite colors. Your child can even help with the decorating. Just pick a different color for every tier. Then use piping bags to add simple accents such as dots or numbers. This allows you to tie all of your child's favorite colors together in one piece.
The party favor can include both your theme and food. If you use a circus theme, then give out bags of cotton candy. Use animal crackers for a safari party. For a princess theme, you can look for candy rings or necklaces.
