This Homemade American Flag Sugar Cookie Fruit Pizza starts with a buttery homemade sugar cookie crust and is topped with creamy vanilla frosting, fresh raspberries, and blueberries for a festive summer dessert.
In a large mixing bowl, cream the butter and sugar until light and fluffy. Beat in the egg and vanilla until well combined. Gradually mix in the flour, then stir in the oats until a soft dough forms. Do not overmix.
Press the dough evenly into a parchment-lined or lightly greased 13 x 18-inch baking sheet. A small pastry roller works well for creating an even layer.
Bake in a preheated 350°F oven for 15 minutes, or until the edges are lightly golden brown.
Transfer the pan to a wire rack and allow the cookie crust to cool completely before adding the frosting.
Prepare the Frosting Layer
Whisk the instant pudding mix and cold milk until smooth. Add the powdered sugar, then gently fold in the thawed whipped topping until fully combined.
Spread a thin layer of frosting evenly over the cooled homemade sugar cookie crust.
Decorate the Flag Sugar Cookie
Arrange the blueberries in the upper left corner to create the stars. Place the raspberries in rows to form the red stripes.
Transfer the remaining frosting to a decorating bag or a zip-top bag with one corner snipped off. Pipe the frosting between each row of raspberries to create the white stripes of the American flag.
Refrigerate until ready to serve. Slice into squares and enjoy.

Notes
Tips
For the best texture, cream the butter and sugar until light and fluffy before adding the remaining ingredients.
Cool the sugar cookie crust completely before adding the frosting so it spreads easily.
Pipe the frosting between the raspberry rows to create the white stripes, or simply spread it over the crust for a quicker version.
Storage & Make Ahead:
Bake the sugar cookie crust up to 2 days in advance and store it tightly covered.
Add the frosting and fruit the day you plan to serve for the freshest results.
