Preheat the oven to 350°F (175°C).
In a bowl, whisk together flour, sugar, baking powder, baking soda, cocoa powder, and salt.
In another bowl, beat eggs and add vegetable oil, buttermilk, red food coloring, and vanilla extract. Mix well.
Combine wet and dry ingredients, mixing until just combined.
Pour the batter into greased and floured cake pans.
Bake for 25-30 minutes or until a toothpick comes out clean.
Allow the cakes to cool completely, then crumble them into bite-sized pieces.
