. Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
In a large bowl, sift together the flour, sugar, baking soda, cocoa powder, and salt.
. In another bowl, whisk together the eggs, oil, buttermilk, food coloring, vanilla extract, and vinegar.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
. Divide the batter evenly between the prepared pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
. Cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
These cake recipes are versatile and can be dressed up or down to suit any occasion.
