- Gradually add in the sifted flour, baking soda, and baking powder to the mixer on low speed until just incorporated.
- Add the vegetable oil, buttermilk, and vanilla extract to the mixture. Scrape down the sides and bottom of the bowl as needed. Be careful not to overmix.
- Evenly pour the batter into the prepared cake pans and bake for 22 to 25 minutes, or until a toothpick inserted into the center comes out clean.
