Equipment

  • 2 Mixing Bowls
  • Measuring Cups and Spoons
  • 1 Whisk
  • Parchment Paper
  • 3 6" Cake Pans
  • Cake Board or Flat Plate for decorating
  • Revolving Cake Stand for decorating, optional but will make it easier
  • Mini Offset Spatula for decorating
  • 2 Piping Bags
  • Decorating Tips of Choice I used a medium round tip and a medium star tip.

Ingredients

For the Chocolate Cake

  • 1 ½ Cups Unsweetened Plant Milk I used So Delicious Coconut Milk
  • 6 tablespoon Canola Oil
  • 1 ½ teaspoon Espresso Powder instant coffee will work, too
  • 1 teaspoon White Vinegar
  • 1 teaspoon Vanilla Extract
  • 1 ½ Cup All Purpose Flour
  • 1 ½ Cups Sugar
  • ½ Cup Dutch-Processed Cocoa Powder
  • 1 ½ teaspoon Baking Soda
  • ¾ tsp Baking Powder
  • ½ teaspoon Kosher Salt

For the Vanilla Buttercream Frosting

  • 1 ½ Cup Vegan Butter, room temperature See note
  • 6 Cups Powdered Sugar, sifted
  • 2 teaspoon Vanilla Extract
  • 3 tablespoon Non-Dairy Milk

For the Ganache

  • ½ Cup Dark Chocolate Chips
  • 6 tablespoon Unsweetened Plant Milk I used So Delicious Coconut Milk

To Decorate

  • 8 Chopped Oreo Cookies, divided
  • 4 halved Oreo Cookies

Instructions

  • Grease three 6-inch cake pans or 2 8-inch and insert parchment circles into the bottom of each of the pans. Preheat oven to 375* F.
  • Into a large measuring cup or medium bowl, add non-dairy milk, canola oil, espresso powder, vinegar and vanilla. Whisk to combine and set aside.
    1 ½ Cups Unsweetened Plant Milk, 1 ½ teaspoon Espresso Powder, 1 teaspoon White Vinegar, 1 teaspoon Vanilla Extract, 6 tablespoon Canola Oil
  • Into a large bowl, sift flour, cocoa powder, baking soda, baking powder and salt.
    1 ½ Cup All Purpose Flour, ½ Cup Dutch-Processed Cocoa Powder, 1 ½ teaspoon Baking Soda, ¾ teaspoon Baking Powder, ½ teaspoon Kosher Salt, 1 ½ Cups Sugar
  • Add the wet ingredients into the dry ingredients and whisk until the mixture is just combined.
  • Portion the batter evenly among the prepared cake pans. If you are weighing, it will be 12 oz per 6 inch pan or 18 oz per 8-inch pan.
  • Bake in a 375* oven for 24-27 minutes, turning halfway through. A toothpick inserted into the center of the cake should come out cleanly.
  • Cool completely before decorating.

Make the Buttercream Frosting

  • In the bowl of a stand mixer fitted with the paddle attachment, cream the vegan butter until completely smooth.
    1 ½ Cup Vegan Butter, room temperature
  • Add the powdered sugar and mix on low until combined. Add the vanilla and non-dairy milk and mix on medium until light and fluffy.
    6 Cups Powdered Sugar, sifted, 2 teaspoon Vanilla Extract, 3 tablespoon Non-Dairy Milk

To Decorate

  • Add 1 cup of buttercream into a medium bowl. Combine with ½ of a cup of chopped Oreos and stir until well combined. You should still have some chopped Oreos leftover.

  • Fit a piping bag with a round tip and fill with plain vanilla buttercream.
  • Place a cake board onto a turntable and place a dollop of buttercream directly onto the board to keep the cake stable.
  • Place a cake layer onto the board. Using the piping bag, pipe a vanilla buttercream boarder around the edge of the cake layer.
  • Dollop half of the Oreo buttercream mixture onto the center of the cake layer and spread it out evenly. Top with a handful of additional chopped Oreos and top with another cake layer. Repeat.
  • Frost the exterior of the cake with the remaining plain vanilla buttercream. Place the cake into the refrigerator. (See Note)

Make the Ganache

  • Place the chocolate chips into a small cup or bowl- something that will be easy to pour from.
    ½ Cup Dark Chocolate Chips, 6 tablespoon Unsweetened Plant Milk
  • Bring non-dairy milk to a boil in a small saucepan. Then, pour the milk over the chocolate chips and cover. Wait 5 minutes.
  • Remove the cover and whisk until the ganache is homogenous and shiny. About 30 seconds.

Top the Cake

  • Remove the cake from the fridge. Pour about ¾ of the ganache onto the center of the cake and use a small offset spatula to push the ganache over the sides of the cake. Place back in the fridge to set. See note!
  • Once the ganache is set, top with more buttercream and more oreo cookies to finish. Enjoy!

Notes

For the frosting, be sure to use a vegan butter that comes in stick form. My top recommendation is Earth Balance Soy Free buttery Sticks.
It is crucial to refrigerate the cake for at least 30 minutes before topping with ganache. You want the buttercream to be firm so it doesn't melt from the heat of the ganache.
Similarly, it is important to refrigerate for about 20 minutes after adding the ganache drip so the ganache has time to set.
