Flag Sheet Cake Recipes

FLAG CAKE

Steps:

• Heat the oven to 350 degrees F.
• Butter and flour an 18 by 13 by 1 1/2-inch sheet pan.
• Cream the butter and sugar in the bowl of an electric mixer fitted with the paddle attachment on high speed, until light and fluffy. On medium speed, add the eggs, 2 at a time, then add the sour cream and vanilla. Scrape down the sides and stir until smooth.
• Sift together the flour, cornstarch, salt, and baking soda in a bowl. With the mixer on low speed, add the flour mixture to the butter mixture until just combined. Pour into the prepared pan. Smooth the top with a spatula. Bake in the center of the oven for 20 to 30 minutes, until a toothpick comes out clean. Cool to room temperature.
• For the icing, combine the butter, cream cheese, sugar, and vanilla in the bowl of an electric mixer fitted with the paddle attachment, mixing just until smooth.
• Spread three-fourths of the icing on the top of the cooled sheet cake. Outline the flag on the top of the cake with a toothpick. Fill the upper left corner with blueberries. Place 2 rows of raspberries across the top of the cake like a red stripe. Put the remaining icing in a pastry bag fitted with a star tip and pipe two rows of white stripes below the raspberries. Alternate rows of raspberries and icing until the flag is completed. Pipe stars on top of the blueberries.
• I serve this cake right in the pan. If you want to turn it out onto a board before frosting, use parchment paper when you grease and flour the pan.

AMERICAN FLAG SHEET CAKE

Steps:

• Preheat oven to 350 degrees Fahrenheit. Grease a 13" x 18" rimmed baking sheet - spray with your favorite non-stick spray or wipe down with a bit of oil.
• In a large bowl, sift together the flour, sugar, cocoa powder, baking soda, and salt. Stir with a whisk or a wooden spoon to combine.
• Using the back of a wooden spoon, make three indents in the flour mixture. Into one indent, pour the vanilla. Into the second, pour the vinegar. Into the third, add the oil. Pour the water over the top. Stir well until combined.
• Spread the batter in the baking sheet and, using an offset spatula, spread the batter to the edges of the pan, making it as level as possible. Bake for 14-17 minutes; until the sides have pulled away from the edge a bit and a toothpick inserted into the center comes out clean. Pull the cake out of the oven and set on a wire rack to cool completely.
• While the cake cools, make the buttercream frosting. Using a stand mixer or hand mixer, whip the butter until smooth. Add a cup of powdered sugar and mix in at low speed. Add remaining powdered sugar, a cup at a time, and mix until smooth. Add the vanilla and the milk. Mix until smooth and an easily spreadable consistency. If too thick, add more milk - just a teaspoon at a time, as it thins out easily. If too thin, add more powdered sugar.
• Once the cake is completely cool, frost it with the buttercream - simply smooth it all over the top in a thin, even layer.
• Now, it's time to decorate! Visually divide the cake into thirds and, in the top third, fill in with rows of blueberries. Add rows of halved strawberries next; the amount of stripes depends on the size of your strawberries, so just eyeball it, and if you need to adjust the berries, you can use the tip of the offset spatula or the tip of a spoon to create stripes in between the rows of berries.
• Serve as soon as possible; it can be made ahead of time, but the strawberries will probably start to leak after awhile, so keep that in mind.

FLAG SHEET CAKE

Steps:

• Trim any rough edges from cakes using a serrated knife. Place four strips of parchment paper around the perimeter of a serving platter. Place first layer, bottom side up, on serving platter. Using an offset spatula, spread cake with 2 1/2 cups frosting. Top with remaining layer, bottom side up. Spread entire cake with 5 1/2 cups frosting. Place remaining frosting in a large pastry bag fitted with a star tip (such as Ateco #35). Remove parchment paper strips.
• Using the tip of a toothpick, outline the shape of a flag on the cake. Fill the upper left-hand corner with a single layer of blueberries. Place one row of raspberries across upper edge of cake to form first red stripe. Pipe one row of stars just below raspberries to form first white stripe. Repeat process with remaining raspberries and frosting until you have 7 red and 6 white stripes.
