Ingredients

  • 12 oz blueberries
  • 48 oz fresh raspberries

For the Vanilla Cake

For the Cream Cheese Frosting

  • 1 cup salted butter softened (two sticks)
  • 16 ounces cream cheese softened (two 8 ounce blocks)
  • 2 pounds powdered sugar 32 ounces or about 7 1/2 cups
  • 2 teaspoons vanilla extract

Instructions

For the Vanilla Sheet Cake

  • Preheat oven to 325 degrees. Line sheet pan with parchment paper and spray well with nonstick cooking spray and set aside.
  • In a large bowl, whisk flour, baking powder, baking soda and salt together to combine. Set aside.
  • In a liquid measuring cup, stir milk and vanilla together. Set aside.
  • In a separate large bowl, mix butter, oil and sugar together until combined. Mix in eggs and egg whites, one at a time, until mixture becomes very light and fluffy. Scrape the sides of the bowl and mix again briefly.
  • Alternate adding in flour mixture with milk mixture, being sure to start and end with flour. Scrape the sides and mix again to ensure a smooth batter.
  • Pour into prepared sheet pan and smooth the top. Bake 15 minutes in the lower 2/3rds of the oven. Cake will be done when a toothpick comes out clean or mostly clean with a few moist crumbs. Depending on your oven, this will take more or less time. Anywhere between 12-20 minutes.
  • Cool completely before frosting.

For the Cream Cheese Frosting

  • Place all ingredients into a large bowl. Stir with a hand mixer (or stand mixer) until completely combined, thick and smooth. Scrape the sides and stir again briefly to ensure a smooth frosting.

To Decorate

  • Over cooled cake spread half of the cream cheese frosting in an even layer. It doesn't have to be perfect since its getting covered with berries and more frosting.
  • With a toothpick or butterknife, outline the best you can the American flag. You don't need all 13 stripes, I only had room for 7.
  • Fill the upper left rectangle with blueberries. Then alternate adding raspberries to each flag line. I started and ended with a red stripe (so four red stripes total and three white stripes).
  • With remaining cream cheese frosting, place in a piping bag with a star shaped tip. Pipe on a couple of 'stars' then pipe two lines in each place of a white stripe.
