Some bunny is turning one — and it is time to hop to it! A bunny theme is one of the sweetest choices for a first birthday, and with a boyish twist of greens, blues, and rustic textures, it feels fresh instead of frilly.
This guide walks you through the whole party: decorations, balloons, the cake moment, and favours guests will actually keep. Every idea below works on its own, so take what fits your space and your budget — and leave the rest.
Bunny Birthday Party Decorations
Set the stage with decorations that balance whimsy and boyish charm. The trick is the palette: sage green, navy or soft blue, and natural textures like wood, burlap, and kraft paper keep the bunnies from feeling too sweet.
Start with a plaid fabric backdrop — green or navy — with a simple bunny silhouette cut from cardstock or felt. Layer in wooden crates, potted herbs or eucalyptus, and a few carrot bunches (real ones!) for a garden-party feel that costs almost nothing.
Decorating Tip: Scatter kraft-paper “carrot patch” signs around the yard or party room — hand-lettered signs are free and photograph beautifully.

Bunny Birthday Balloons
No first birthday is complete without balloons, and for a boy bunny party the mix matters: soft greens, navy blues, and warm beige instead of pink. A balloon garland in those three tones makes an instant photo backdrop.
Add one or two statement pieces — a giant bunny foil balloon or carrot-shaped balloons — and let the latex garland do the rest. Anchor one end over the cake table and let the other trail toward the floor.
Balloon Tip: Inflate the garland the night before and store it in a spare room — it holds fine overnight and saves party-day stress.

Cake, Smash Cake, and High Chair Setup
The cake moment is the heart of a first birthday — it is the photo everyone waits for. Plan three pieces: the main cake for guests, a small smash cake for the birthday boy, and a decorated high chair to frame it all.
Main Cake:
Go two tiers if you are feeding a crowd: decorate with edible greenery, a plaid-patterned band, and a fondant bunny topper. The topper is the one piece worth ordering — everything else can be simple.
For a playful nod to the theme, serve carrot cake with cream cheese frosting. Guests love the wink, and it tastes like a proper celebration cake.
Smash Cake:
Keep the smash cake small and simple — a single layer with white frosting, mini fondant bunny ears, or a tuft of greenery on top. The birthday boy provides the drama; the cake just needs to look sweet before the destruction starts.
Another cute option: decorate the smash cake like a carrot patch, with crushed cookie “dirt” and candy carrots poking out of the top.

High Chair Setup:
The high chair is the stage, so dress it: drape a banner reading “Some Bunny Is 1” across the tray, and skirt the legs with plaid fabric or a blue-green tassel garland.
Place a bunny plush beside the chair — not on the tray, where it will meet frosting — for those wide-eyed “before” photos. Keep wipes within arm’s reach but out of frame.
Photo Tip: Shoot the high chair setup before the party starts, while it is pristine — you will want at least one clean photo of all your hard work.
Bunny Birthday Party Favors
Send guests home with favours that match the theme and will not be thrown away by dinnertime. Carrot-shaped treat bags filled with candy, crackers, or bunny-shaped cookies are the obvious winner — cheap, cute, and on theme.
Bunny-ear headbands are another hit: kids wear them during the party (instant photo ops) and take them home. For the grown-ups, a small bag of “bunny bait” — white chocolate-covered pretzels — goes down well.
Favour Tip: Set the favours out near the exit, not on the tables — otherwise half of them get opened (and lost) before anyone leaves.

Final Touches for Your Boy-Themed Bunny Bash
Keep the whole party boy-friendly with a few playful extras: a small garden-themed play corner with toy gardening tools, or a bubble station for wiggly toddlers between activities.
Blend those Peter Rabbit vibes with rustic charm and splashes of blue and green, and you have a “Some Bunny Is One” party that feels thoughtful without feeling overdone. Take plenty of photos — then put the phone down and enjoy it. Hoppy first birthday to your little bunny!
