How to Make this Sugar Cookie Flag Cake Recipe
Making this flag cake is so easy! The sugar cookie base is sturdy, yet chewy and tender while the frosting adds a layer of creamy sweetness that perfectly holds the fruit flag topping! Here’s everything you need.
Ingredients
Be sure to see the recipe card below for the full listing of ingredients, instructions, notes, and estimated nutritional information.
Sugar Cookie Layer
For the sugar cookie layer, you’ll need: butter, sugar, eggs, flour, baking powder, salt, and eggs.
Flag Layer
For the flag layer, you’ll need butter, powdered sugar, vanilla, salt, half-and-half, blueberries, and raspberries.
You’ll also need a rimmed sheet pan and an electric mixer. If you decide you’d like to pipe the frosting decoratively, you’ll need piping bags (or a clean zip-top bag) along with a 1M Star Tip.
Step by Step Instructions
- Cream together the butter and sugar until light and creamy, then add the eggs, followed by the flour, baking powder, salt, and vanilla extract.
- Butter a rimmed baking sheet and press the sugar cookie dough into the pan.
- Bake the sugar cookie cake layer, remove from the oven and allow to cool completely.
- Cream together the butter and powdered sugar until light and creamy, then add the vanilla extract, salt, and half and half.
- Beat the frosting until it is light, fluffy and smooth.
- Spread the frosting on the cool sugar cookie layer.
- Arrange the blueberries and raspberries to make the American flag design. Optionally, you can pipe more buttercream frosting between the raspberries for the stripes in the flag.
- Sprinkle with powdered sugar (optional) and serve.
Pro Tips from Our Kitchen
- Room-temperature ingredients are key to that perfect chewy texture.
- Don’t overbake: the center should look just set for maximum softness.
- For make-ahead: Bake the base up to 2 days ahead. Frost the day before and add berries shortly before serving.
- Storage: Refrigerate leftovers up to 3–4 days. Bring slices to room temperature before enjoying for the best flavor and texture.
Variations to Try
- Use our original single batch in a 9×13 pan for a smaller gathering.
- Add sprinkles into the dough for extra fun.
- Try lemon zest in the dough and frosting for a bright summer twist.
This Sugar Cookie Flag Cake has been a huge hit in our home. I believe it will be in yours, too. It’s simple enough for beginners and impressive enough for celebrations. And it is so much fun to make with your family or friends!
Storage & Make-Ahead Instructions
This Sugar Cookie Flag Cake is wonderfully make-ahead friendly, making it perfect for busy holiday weekends.
Storage:
- Unfrosted cookie base: Store at room temperature for up to 2 days or refrigerate for up to 4 days, tightly wrapped in plastic wrap or foil.
- Frosted cake (no fruit): Refrigerate in an airtight container or covered well for up to 4 days.
- Fully decorated with berries: Best enjoyed within 1–2 days. Refrigerate for up to 3–4 days total. Note that the berries may release a bit of juice after day 2, so add them as close to serving time as possible for the prettiest presentation.
Make-Ahead Tips:
- Bake the cookie base up to 2 days in advance.
- Prepare the frosting up to 3–4 days ahead and store it in the refrigerator. Let it come to room temperature and re-whip briefly before spreading.
- Assemble and frost the day before your event, then add the fresh berry flag topping the morning of or right before serving.
Bring slices to room temperature for 15–30 minutes before serving for the best soft, chewy texture.
Recipe Variations
Half Sheet Pan Version (Full Recipe – serves 20–30) Use the full doubled recipe as written in the recipe card below for a large crowd or big gatherings.
Smaller 9×13-inch Pan Version (Half Recipe – serves 12–18) Simply cut all ingredients in half:
- Cookie Base: 1 cup butter, 1½ cups sugar, 1 large egg, 2¼ cups flour, ½ tsp baking powder, ½ tsp kosher salt, 1 tsp vanilla.
- Frosting: Use half the amounts listed (or make our standard single-batch cream cheese frosting or buttercream).
- Bake time: 18–24 minutes in a 9×13-inch pan.
- Decoration: Same flag design, just on a smaller scale—still looks beautiful!
Other Fun Variations:
- Confetti Cake: Add ½ cup sprinkles to the dough for a confetti version.
- Citrus Cake: Mix lemon zest into the dough and frosting for a bright citrus twist.
- Chocolate Cake: Try our chocolate sugar cookie variation as the base for a fun twist.
Store-Bought Shortcut:
While I prefer to bake and cook from scratch, I know there are times a shortcut may be useful! Here are some quick substitute ideas you may find helpful.
- Store-bought sugar cookie dough in place of the homemade sugar cookie layer. You’ll need 2 large rolls.
- Store-bought white frosting in place of the homemade buttercream. You’ll need at least 6 cups. Ask your favorite bakery, your grocery bakery, or use premade frosting in the tubs.

The BEST Sugar Cookie Flag Cake
Equipment
- Stand Mixer or hand mixer
Ingredients
SUGAR COOKIE LAYER:
- 2 cups butter, room temperature
- 3 cups granulated sugar
- 2 large eggs, room temperature
- 4 1/2 cups all-purpose flour, spooned and leveled
- 1 teaspoon baking powder
- 1 teaspoon kosher salt
- 2 teaspoons vanilla extract
FLAG LAYER:
- 2 cups butter, room temperature
- 8-9 cups powdered sugar
- 4 tablespoons heavy cream
- 2 teaspoons vanilla extract
- pinch kosher salt
- 50 blueberries
- 3 pints fresh raspberries
Instructions
- Prep. Preheat the oven to 350º F. Butter the rimmed baking sheet and line with parchment if you prefer to remove from the pan for decorating and serving.
- Make the cookie dough: Cream together the butter and sugar until light and fluffy, about 3 minutes. Add eggs and vanilla, mixing until well combined. Stir in flour, baking powder, and salt until just combined.
- Press into pan: Evenly press the dough into the prepared pan (aim for about ½–¾ inch thickness).
- Bake: Bake 22–28 minutes until the edges are lightly golden and the center is set but still soft. Cool completely in the pan. If using parchment paper to remove from the pan, remove once cooled for decorating.
- Frost: Spread the frosting evenly over the cooled cookie cake.
- Decorate the flag: In the upper left corner, create a blueberry rectangle for the blue field. Arrange raspberries or strawberries in horizontal stripes across the rest of the cake, alternating with white frosting stripes. Optional: Use a 1M Star Tip and add frosting between the raspberry stripes.
Notes
- Room temperature ingredients are essential for the best chewy texture. Take butter and eggs out 1–2 hours before baking.
- Pan size matters: This doubled recipe is formulated for a standard half sheet pan (13×18-inch). For a 9×13-inch pan, use half the recipe (see Variations in the recipe post).
- Don’t overbake: The center should look just set and still soft when you remove it from the oven. It will continue to firm up as it cools.
- Make-ahead friendly: The unfrosted cookie base can be baked up to 2 days in advance. Frosting can be made up to 4 days ahead and stored in the refrigerator.
- Storage: Refrigerate the assembled cake for up to 3–4 days. Add fresh berries as close to serving as possible for best appearance and texture. Bring slices to room temperature before serving.
- Frosting options: Both the doubled buttercream and our classic cream cheese frosting work beautifully. Use buttercream for easier piping/stability or cream cheese for tangy flavor.
- Freezing: The unfrosted cookie base freezes well. Wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before frosting and decorating.
- High altitude note: If baking above 3,000 feet, you may need to increase oven temperature by 15–25°F or add an extra 2–3 tablespoons of flour.
