What Makes a Cookie Monster 1st Birthday Work
For a first birthday, less really is more.
A great Cookie Monster 1st birthday focuses on:
- one strong color (blue)
- one character moment

- one smash cake moment
That’s it.
You don’t need games, schedules, or entertainment.
Choose Your Cookie Monster Color Palette
Lock this in first — it makes everything else easy.
Best color combinations:
- blue + white
- blue + white + black
- blue + white + light brown (cookie tones)
Avoid adding too many extra colors. The cleaner the palette, the cuter the photos.

You only need a few key pieces.
Decor ideas that work beautifully:

That’s where 90% of your photos will happen.
