1 vanilla white cake box plus ingredients required for a 9 x 13 pan, using egg white version on box

  • red gel paste
  • blue gel paste

Vanilla Frosting:

  • ½ cup unsalted butter softened
  • 3 cups powdered sugar
  • 2 tablespoons almond milk or milk
  • 1 teaspoon vanilla
  • teaspoon salt


  • Red white and blue sprinkles



    Retro Red White and Blue Cake:

    • Make vanilla cake according to box instructions, then evenly divide your cake batter into 2 other small bowls, keeping the vanilla in the original bowl you mixed it in. Use red gel paste in one bowl and blue gel paste in the other bowl and mix until color desired.
    • Pour the white cake batter into a 9 x 13 cake pan, sprayed with non-stick spray. Then add the blue or the red by pouring on top, then swirl with a knife a few swirls, but not a lot, or you'll get other colors and it won't be red, white and blue.
    • Bake cake until done and let cool.
    • Once cake has cooled, make the frosting.

    Vanilla Frosting:

    • Cream butter for a couple of minutes and then add in the powdered sugar, milk, vanilla, salt until smooth and creamy.
    • Frost cake and sprinkle some sprinkles on top and serve.
