Description

This vegan dirty chai cake is soft, moist, and packed with warming chai spices. Made with a simple dairy-free cake batter and topped with creamy coffee-infused frosting, it's the perfect combination of sweet, spiced, and comforting.

 


Ingredients

Units Scale
  • FOR THE HOMEMADE CHAI SPICE:
  • 2 and 1/2 teaspoons ground cinnamon
  • 1 and 1/4 teaspoons ground ginger
  • 1 and 1/4 teaspoons ground cardamon
  • 1/2 teaspoon ground allspice
  • FOR THE CAKE:
  • 240 ml (1 cup) soy milk or your favorite type of dairy-free milk ;
  • 1 tablespoon white wine vinegar
  • 210 g (1 and 1/2 cups all-purpose flour, sifted)
  • 150 g (3/4 cup) soft brown sugar
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 3 and 1/2 teaspoons chai spice
  • 80 ml (1/3 cup) vegetable oil ;
  • 1 tablespoon vanilla extract
  • FOR THE DIRTY CHAI FROSTING:
  • 70 g vegan butter, softened
  • 70 g vegan cream cheese, softened
  • 250 g (2 cups) powdered sugar (icing or confectioners sugar)
  • 1 teaspoon vanilla extract
  • 1 teaspoon instant coffee, dissolved in 1 tablespoon hot water (optional)
  • 1 teaspoon chai spice mix

Instructions

  1. Mix the Chai Spice: Mix the ground cinnamon, ground ginger, ground cardamom, and the ground allspice. Set aside. You can put the spice mix in a small jar as you will have some leftovers that you can use for next time.
  2. Set the Oven to 180°C (350°F)  and grease or line an 8-inch round cake pan. 
  3. Create the "Buttermilk": Start by combining milk with white vinegar and letting it sit for 5 minutes. This will create a vegan buttermilk that’ll help make your cake extra moist and fluffy.
  4. Dry Ingredients: In a large mixing bowl, whisk together the sifted flour, soft brown sugar, baking powder, baking soda, salt, and chai spice. 
  5. Mix the Wet Ingredients: Add the vegetable oil, and vanilla extract, to the milk mixture. Stir until combined.
  6. Make the Batter: Slowly pour the wet ingredients into the dry mixture, stirring just until combined. Avoid overmixing—lumps are okay! The batter will be thin/runny, this is normal. 
  7. Bake the Cake: Pour the batter into your prepared 8-inch round cake pan. Bake at 180°C (350°F) for 30–35 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs. Allow the cake to cool completely before frosting.
  8. FROSTING: 
  9. While the cake is cooling, let’s make that chai-spiced frosting! If you don't like coffee then simply leave it out. 
  10. Make the Dirty Chai Frosting: Beat the softened vegan block butter and vegan cream cheese together until smooth and creamy.
  11. Gradually add the sifted powdered sugar, vanilla extract, 1 teaspoon chai spice mix, and the cooled, dissolved instant coffee (if using). Beat until smooth and fluffy.
  12. Frost the Cake: Once the cake has completely cooled, spread the frosting generously over the top. Finish with a light dusting of chai spice and decorate as desired.

Notes

Don’t Skip the Vinegar: The white vinegar and milk combo creates a vegan “buttermilk,” which helps make the cake light and fluffy. It’s essential for texture, so don’t leave it out!

Use Vegan Butter (Not Margarine): For the frosting, stick with vegan block butter, as it gives better texture and flavor than spreadable margarine.

Avoid Overmixing: Once you combine the wet and dry ingredients, mix just until combined. Overmixing can lead to a tough cake. Stir gently for a tender crumb.

Thin Batter: The cake batter will be relatively runny, and that's normal. Don't add extra flour. This helps keep the cake moist and tender.
