Preheat your oven to 350°F (175°C). Grease and flour two round cake pans.

In one bowl, whisk together flour, cocoa powder, baking soda, baking powder, and salt.

In another bowl, mix oil and sugar until smooth. Add eggs one at a time, then stir in buttermilk, red food coloring, vanilla extract, and vinegar.

Gradually combine wet ingredients with dry ingredients until just mixed.

Pour batter evenly into prepared pans and bake for 25-30 minutes or until a toothpick comes out clean.

Cool cakes in pans for ten minutes before transferring to wire racks. Once cool, frost with cream cheese frosting.
