Preheat oven to 350*F. Grease two 8-inch round cake pans and insert a parchment circle into the bottom of each pan.
In a large bowl, combine flour, sugar, cocoa powder, baking powder, baking soda, and salt. Whisk to combine.
2 Cup All-Purpose Flour, 1 ¾ Cups Granulated Sugar, ¾ Cup Cocoa Powder, sifted, 2 ¼ teaspoon Baking Powder, ¾ teaspoon Baking Soda, ¾ teaspoon Kosher Salt
In a medium bowl, combine non-dairy milk, melted non-dairy butter, non-dairy yogurt, instant espresso, and vanilla. Whisk well until the espresso powder is completely dissolved. Pour the wet ingredients into the dry ingredients and whisk to form the batter. Then, carefully add boiling water and whisk again until combined. It will look on the runny side, and that is okay!
1 Cup Unsweetened Non-Dairy Milk, 10 tablespoon Non-Dairy Butter, melted, ½ Cup Unsweetened Non-Dairy Yogurt, 2 teaspoon Instant Espresso, 2 teaspoon Vanilla Extract, 1 Cup Boiling Water
Divide the batter between two prepared 8-inch round cake pans. Bake the cakes in a 350*F oven for 33-36 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
Allow the cakes to cool in their pans for 30 minutes, then turn them out onto a parchment-lined baking sheet to cool completely.
