Waves of Red, White and Blue - Sparkle Dazzle Shine

Waves of Red White and Blue is a breath taking site. But, the best kind of flag is the one you can eat, right? Today, I’m sharing my take on a wavy 4th of July flag sugar cookie—a sweet little design that captures all the patriotic flair of Old Glory, with a bit of icing artistry (and sparkle, of course).

This cookie design uses a wavy flag cutter, and I leaned into that flowing motion by loosening my icing style just a smidge. Think gently swooping lines and soft curves—not perfection, but purpose. Just like a flag caught in a summer breeze.

Decorating Notes:

I started by outlining the blue section in a not-so-perfect block (on purpose!), then flood filled it and let it set for about 10 minutes.
Next came the imperfect white stripes, then the red, letting each one dry slightly before adding the next. This helps keep the colors crisp and distinct.
I finished by adding small outlines to each section in their matching color for a little extra pop and dimension.
A few dots of blue icing and some carefully placed star sprinkles finish the look. (Hello, trusty tweezers!)

If you don’t have a flag-shaped cutter, no worries at all! A simple rectangle cookie will do the trick:

Leave negative space around your design and outline the flag directly on the cookie. Got to love that negative space it just makes the design pop.
Or fill the rectangle with a base color, let it set, and build your flag design on top.
For a more intermediate look, outline and fill each flag section separately (blue, white stripes, then red), allowing for dry time in between.

I always color and thin my royal icing the night before decorating—this gives the colors time to develop and lets the consistency settle. I also keep extra thick icing on hand in case the flood icing thins out a bit by decorating time.

It’s all about flexibility, ease, and making room for those little imperfections that make handmade cookies so sweetly unique.
