Preheat your oven to 350°F (175°C) and grease two round baking pans.

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

In another bowl, mix the sugar and vegetable oil until smooth. Add eggs one at a time, then incorporate buttermilk, red food coloring, and vanilla.

Gradually add the dry ingredients to the wet mixture until just combined—avoid overmixing.

Divide the batter between the prepared pans and bake for 25-30 minutes or until a toothpick comes out clean.

Allow cakes to cool completely before generously frosting with cream cheese frosting.
