Preheat oven to 350* F. Grease two 8-inch round cake pans and insert a parchment circle into the bottom of each pan for east removal.
In a large bowl, combine non-dairy milk and lemon juice to make a vegan buttermilk. Mix and set aside.
1 ½ Cup Non-Dairy Milk, 2 tablespoon Lemon Juice
In a medium bowl, combine flour, cocoa powder, baking powder, baking soda and salt. Whisk to combine and set aside.
2 ⅔ Cup All-Purpose Flour, 2 tablespoon Cocoa Powder, sifted, 1 tablespoon Baking Powder, ¼ teaspoon Baking Soda, ¼ teaspoon Kosher Salt
Into the large bowl with the non-dairy milk mixture, add sugar, melted vegan butter, vanilla and red gel food coloring. Whisk well to ensure the food coloring is completely mixed. Then add the dry ingredients and whisk to form the batter.
1 ½ Cup Sugar, 9 tablespoon Vegan Butter, melted and cooled, 1 tablespoon Vanilla Extract, 2 ½ teaspoon Red Gel Food Coloring
Divide the cake batter between the two prepared 8-inch round cake pans. If you are weighing, it will be about 20 ounces per pan. Then, bake in a 350* oven for 26-29 minutes or until a toothpick inserted into the center of a cake comes out clean. Allow the cakes to cool completely before frosting. (See Note)
