Ingredients

  • 2 cups all-purpose flour
  • 1 3/4 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 2 tsp baking soda
  • 1 tsp baking powder
  • 1/2 tsp salt
  • 1 1/2 cups unsweetened almond milk (or other plant-based milk)
  • 2 tsp apple cider vinegar
  • 1/2 cup vegetable oil
  • 1 cup hot coffee (or hot water for milder flavor)
  • 2 tsp vanilla extract
  • 1/2 cup vegan butter (for frosting)
  • 1/4 cup unsweetened cocoa powder (for frosting)
  • 2 1/2 cups powdered sugar (for frosting)
  • 2–3 tbsp plant-based milk (for frosting)
  • 1 tsp vanilla extract (for frosting)

Directions & Preparation

  1. Preheat your oven to 350°F (175°C) and grease a 13×18 inch sheet pan.
  2. In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking soda, baking powder, and salt until well combined.
  3. In a separate bowl, combine the almond milk and apple cider vinegar. Let it sit for about 5 minutes to create a vegan buttermilk.
  4. Add the vegetable oil, hot coffee, and vanilla extract to the vegan buttermilk, whisking until smooth.
  5. Pour the wet ingredients into the dry ingredients, stirring gently until just combined. Take care not to overmix; a few lumps are fine.
  6. Pour the batter into the prepared sheet pan, spreading it evenly with a spatula.
  7. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
  8. Once baked, remove the cake from the oven and let it cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
  9. While the cake cools, prepare the frosting by beating the vegan butter in a medium bowl until creamy.
  10. Add the cocoa powder, powdered sugar, vanilla extract, and 2 tablespoons of plant-based milk. Beat until smooth and adjust the consistency with more milk if necessary.
  11. Once the cake is completely cool, spread the frosting evenly over the top using a spatula. Slice and serve to enjoy!
