The Best Ever Vanilla Cake

My absolute favorite vanilla cake! 

Author Caffeine & Fist Bumps


  • 1 18.25 package of white cake mix
  • 1 cup all purpose flour
  • 1 cup white sugar
  • 3/4 tsp salt
  • 1 1/3 cup water
  • 1 cup sour cream
  • 1 tbsp vanilla extract feel free to swap out vanilla extract for a different flavor such as orange or lemon!
  • 2 eggs if you want the cake to be more of a white color, use 4 egg whites instead of 2 whole eggs


  1. Pre-heat oven to 350 degrees. Grease and flour your cake pans.

  2. In a large mixing bowl, empty the package of white cake mix and add all dry ingredients. Stir together until combined. Then, add all wet ingredients and mix until no longer lumpy. I prefer to use my stand mixer, but you could definitely use a mixing bowl and a large spoon.

  3. Pour batter into greased and floured pans, filling them about halfway up to allow for cake to rise in oven.

  4. Bake until top is golden and a toothpick, inserted into the middle of the cake, comes out clean. Timing will vary based on the size pan you use, so keep an eye on the cake as it bakes.

  5. Before frosting, allow the cake to cool.

Recipe Notes

I often double this recipe if making a tiered cake. As an example, a double batch made enough for this 2-tiered cake (three 8" layers on the bottom and two 5" layers on the top). I also had enough left for 1 additional 5" layer.

This recipe does well for cupcakes, too!
