How to Make Cake Mix Extender

  1. Preheat your oven to the temperature specified on your cake mix box.
  2. In a medium bowl, whisk together the oil, eggs, and vanilla extract until well combined.
  3. Gradually add the sour cream, whisking until smooth.
  4. Gently fold the dry ingredients (flour, baking powder, and salt) into the wet ingredients until just combined. Be careful not to overmix.
  5. Pour the cake mix batter into a large bowl.
  6. Add the wet ingredients (from steps 2-3) to the cake mix batter and gently fold until just combined. Do not overmix.
  7. Pour the batter into a greased and floured 13x9 inch baking pan.
  8. Bake according to the directions on your cake mix box, adding 5-10 minutes to the baking time. Start checking for doneness around the time indicated on the box. A toothpick inserted into the center should come out clean.
  9. Let the cake cool completely in the pan before frosting and serving.
