Ingredients for Making Vegan Oreo Cake
To make this eggless Vegan Oreo Cake you will need:
Flour: Just regular old all purpose for this recipe.
Baking Soda and Baking Powder: A combination of baking soda and baking powder give the cake a nice lift.
Salt: For balance.
Cocoa Powder: My favorite cocoa powder is the Whole Foods 365 brand. It lends a dark, rich flavor to this Vegan Oreo Cake.
Sugar: just regular granulated sugar, here.
Non Dairy Milk: I used So Delicious Coconut Milk, as I do for most of my baking.
Instant Espresso: Instant espresso helps round out the cocoa flavor, making it more intense. But, you can sub instant coffee here if you can't fins instant espresso.
Vinegar: I use vinegar to make a kind of vegan buttermilk. This will activate the baking soda and help the cake rise. This is how we are able to keep this Vegan Oreo Cake totally eggless.
Vanilla: Vanilla also helps round out the cocoa flavor.
Canola Oil: Canola oil keeps this cake nice and moist.
Oreos: It wouldn't be a Vegan Oreo Cake without Oreos. So, the Oreos are chopped up and mixed with buttercream to fill the cake and then placed on top as decoration.
Ganache: The ganache is optional here. But I recommend it. Its an extra step, but the payoff is big in look and taste.
Vegan Vanilla Frosting: You will need one and a half recipes of my Vegan Vanilla Frosting to fill and frost this cake. But, if you like, you could just buy store bough and skip the step.
How to Fill the Vegan Oreo Cake
First things first, make the vegan cookies and cream filling for the cake. To do this, simply combine one cup of frosting with a half cup of chopped Oreos and stir.
Second is the most important step. Pipe a boarder around the outside of the cake layer with vanilla buttercream. This will keep the exterior of the cake clean.
Then, dollop half of the cookies and cream mixture onto the center of the cake and spread it evenly.
Next, top that with a handful of chopped Oreos.
Finally, top with the next cake layer and repeat!
Once the cake is stacked, frost the exterior with Vanilla Frosting as you would with any other cake. My favorite tool is a mini offset spatula.
Making Vegan Ganache
Okay, the ganache for this Vegan Oreo Cake is optional. But its so easy to make!
Ganache only requires two ingredients: a liquid and chocolate. To keep it extra easy, I used chocolate chips. And for the liquid, use the same milk that you used to make the chocolate cake.
Add the chocolate chips to a heatproof cup, mug or small bowl. The key is to use something that you can easily pour with.
Pour the plant milk into a small sauce pan and bring it to a boil.
Pour the hot milk over the chopped chocolate and cover it using a plate.
Set a timer for 5 minutes.
After 5 minutes, whisk the mixture together until the ganache is homogenous and looks glossy. About 30 seconds.
There are two important things here.
First, is to use the ganache immediately. So don't make the ganache until the exterior of the cake is frosted and its in the refrigerator. If the ganache cools, simply warm it up in the microwave in 10 second intervals until it is a pourable consistency.
Second, is that the cake is chilled. The buttercream should be firm to the touch or the ganache will melt it.
How to Decorate the Cake
How you finish the Vegan Oreo Cake is totally up to you.
After the ganache set, I used a star tip to pipe around the top of the cake and used Oreo halves and crushed Oreos as decoration.
