To Make The Buttercream Frosting:

Cup of Yum
1. Add the softened butter, salt, vanilla, milk, and about half of the powdered sugar to the bowl of a stand mixer. Mix on low until combined. (You can also use an electric hand mixer and a large bowl).
2. Increase the mixer to medium speed, scraping the sides of the bowl as needed, and mix until the frosting is nice and fluffy. Add the rest of the powdered sugar and mix on low until well combined.
3. If the frosting still seems dry and clumpy, add a splash of milk and mix until smooth. If the frosting seems to runny, add a bit more powdered sugar and mix.
4. When the frosting is your desired consistency, transfer the frosting to a piping bag fitted with a large star tip.

To Make The Flag Buttercream Board:

1. Print out and place the American Flag PDF pattern on a large serving board. Place a sheet of parchment paper on top of the pattern. under a piece of parchment paper. You could free-hand if you want, but we like to keep the lines straight to know which rows get the strawberries, etc.
2. Following the pattern, pipe the frosting in rows on top of the parchment paper. Leave the blue corner of the flag empty for now.
3. Start at the top of the flag and place your strawberry slices in a horizontal line, for the first red stripe. Leave the next line of frosting uncovered, for the first white stripe. Continue alternating with red and white stripes until you have 13 rows total. The first and last stripes should be red.
4. Pipe the remaining corner of the flag and cover it entirely with blueberries. Refrigerate until ready to serve.
