If you’re looking for a show stopping festive, patriotic dessert that tastes heavenly, this is it: The Best American Flag Sourdough Sugar Cookie!
It’s the kind of dessert that draws a crowd because it’s shaped like a flag and topped with the most vibrant summer berries you can find.
This isn’t your average sugar cookie base either because it’s made with a fully fermented sourdough sugar cookie dough, which gives it a soft, tender bite and a deeper, richer flavor that’s naturally easier to digest.

The strawberry, raspberry and blueberry colors really pop against a fluffy, tangy delicious layer of homemade cream cheese frosting. It’s the perfect balance to the sweet sourdough sugar cookie base.
So whether you’re celebrating the 4th of July, Memorial Day or Labor Day, this is the kind of dessert that just may be too stunning to want to eat!

How to make The Best American Flag Sourdough Sugar Cookie Fruit Pizza
Fermented Cookie:
Mix flour, starter, sugar, egg, butter, cornstarch, vanilla and almond extract and salt in a bowl until just mixed together. No need for a mixer, I prefer to use my hands or dough hook for this part.
Cover the bowl and ferment the dough for 4-12 hours.

Optional Cold Ferment: You can place the dough into the fridge at any point during the ferment to bake the next day. This allows the grains to continue to slowly break down but also gives you the flexibility to bake when you need. Be sure to bring the dough to room temperature before rolling out to bake because it will be hardened from the cold butter.

After the ferment (whether you did cold or room temperature) press or roll out the dough onto parchment paper into a large rectangle (resembling a flag) about 1/4 of an inch thick. Optional: Build up a crust along the outside of the dough.
Poke holes all over the dough with a fork to allow for even cooking.

Bake at 350 degrees F for 22-25 minutes until the cookie has golden edges and the top is slightly golden brown. I love to bake mine on a pizza stone, but a cookie sheet works too.
Cool the cookie completely before frosting.
Frosting:
With a hand mixer, mix together softened cream cheese, butter, sugar and vanilla until well combined and there are no more chunks. NOTE: Make sure both the butter and cream cheese are at room temperature. This guarantees a smooth frosting!
Frost the cream cheese overtop the sourdough sugar cookie. Make a thick layer, don’t be shy, it’s the best part 😉

Assemble:
This is where the fun begins! Add blueberries to the top left corner in an array of columns and rows. Making a small rectangular shape.
Beginning at the top row, next to the blueberries, start with the first red stripe. This can be from either strawberries or raspberries.

Underneath the first red stripe, begin the white stripe with either a row of bananas or piping any leftover cream cheese frosting.
Continue creating the red and white stripes all the way down your cookie until your flag is made.

I made this last year for our 4th of July party…it was a huge hit! Of course I’m planning on doing it again this year
Made this last year with my then six year old, but we’d found your recipe so very last minute that we hadn’t any blueberries for the stars portion. We’d recently gone blackberry picking though, and those worked out beautifully. We are of course making it again today (at the request of my now seven year old) who absolutely loves our country, America’s history, and our so beautiful red, white, and blue
Love this! thank you for sharing!
