Ingredients
  

Buttercream Base
  • 2 lb unsalted butter Softened to room temperature.
  • 5 lb powdered sugar Sifted for a smooth buttercream.
  • 3 tbsp heavy cream
  • 2 tsp pure vanilla extract
  • 0.25 salt Pinch.
Flag Decoration
  • 1.5 cup fresh strawberries Hulled and halved.
  • 1 cup fresh blueberries
  • 1 cup heavy whipping cream For whipped cream white stripes.
  • 2 tbsp powdered sugar
  • 0.5 tsp vanilla extract
  • 0.25 red food coloring gel Optional for brighter red stripes.
For Dipping / Serving
  • 1 graham crackers
  • 1 vanilla wafers
  • 1 Nilla cookies
  • 1 pretzels
  • 1 fresh fruit slices

Equipment

  • 1 stand mixer
  • 1 hand mixer

Method
 

Make the vanilla buttercream base
  1. Beat the softened unsalted butter in a stand mixer or with a hand mixer on medium-high for 3–4 minutes until pale and fluffy, pulling down the sides as needed.
  2. Reduce speed to low and gradually add the sifted powdered sugar, one cup at a time, mixing well between each addition until fully incorporated.
  3. Add the heavy cream, pure vanilla extract, and salt, then beat on high for 2 minutes until light, smooth, and spreadable.
Build the American flag design
  1. Spread the buttercream onto a large wooden board, marble slab, or rectangular platter using an offset spatula, smoothing into an even layer with a slightly rustic (not perfectly flat) finish.
  2. Whip the heavy whipping cream with powdered sugar and vanilla until stiff peaks form, then transfer it to a piping bag fitted with a star or round tip.
  3. Create the blue star field in the top-left corner by pressing blueberries in tight rows (4–5 rows works well) gently into the buttercream so they hold.
  4. Pipe or arrange 6–7 horizontal red stripes across the remaining right portion using rows of halved strawberries (cut side down), pressed into the buttercream.
  5. Pipe whipped cream in straight lines between the strawberry rows to form the white stripes.
  6. Stand back and adjust any loose berries, then add piped whipped cream rosettes to the corners if desired.
Serve with dippers
  1. Arrange graham crackers, vanilla wafers, Nilla cookies, and pretzels around the outer edges of the board so guests can scoop easily.
  2. Add fresh fruit slices near the edges, then serve immediately or refrigerate uncovered for up to 2 hours before serving for best results the same day.

Notes

Pro tip: keep the buttercream at room temperature long enough to spread, and press berries firmly so they don’t shift. Refrigerate uncovered up to 2 hours; best assembled and served the same day. Freezing isn’t recommended because the berries and whipped cream textures can break down. For a lighter option, use reduced-fat butter and heavy cream substitutes, but expect a softer spread.
