Preheat the oven to 350°F and prepare two 9-inch cake pans.
Combine flour, sugar, salt, baking powder, and baking soda in a large bowl.
In a separate bowl, mix milk, vinegar, and red food coloring.
Add milk, eggs, and oil to the dry ingredients, whisking until well combined.
Mix hot water with cocoa powder and coffee, then add to the cake batter, gently stirring until combined.
Divide the batter between the pans and bake for 25-30 minutes until a toothpick comes out with moist crumbs.
Whip cream cheese and butter for 5 minutes. Gradually add sugar, whisking to create a light and fluffy frosting.
Level the cakes, saving excess for crumbs. Divide each cake into 2 layers, lightly soaking each layer with milk, covering in frosting, and repeating. Decorate with crumbs.
Chill for 1-2 hours before indulging in this heavenly treat!
