Marble Cake Instructions

  • Preheat the oven to 350℉ (175℃).
  • Grease with oil and line two 8 inch ( 20cm) cake pans with baking paper.
  • Combine milk and lemon juice in a bowl, and let it sit for 15 min until it is curdled.
  • Add sugar and vanilla. Mix with a whisk until sugar is dissolved.
  • Combine and sift dry ingredients ( all purpose flour, corn starch, baking powder, baking soda and salt) to the milk mixture. (except for cacao powder). Mix with a whisk to create a smooth batter.
  • Add melted butter. Mix until well combined.
  • Pour 1/3 of the cake batter into a separate bowl.
  • Prepare cacao paste by combining cocoa powder - hot water in a bowl. Add it to the 1/3 of the cake batter and mix properly.
  • Alternate vanilla batter with chocolate batter into the cake pans. Use a skewer to create a marbled pattern. Tap gently.
  • Bake for about 25 - 30 minutes or until firm to touch.

Chocolate Frosting Instructions

  • Use a mixing bowl fitted with the paddle attachment or a handheld electric whisk.
  • Whip the butter until it is light and fluffy on medium speed with an electric whisk.
  • Add sifted powdered sugar in 2 parts.
  • Mix on medium speed until it is light-smooth for 4-5 minutes.
  • Add sifted cocoa powder and mix until combined.
  • Pour cream, vanilla, salt and mix until fluffy and smooth.

Cake Assembly Instructions

  • Trim a thin layer of both cakes to level them with a serrated knife to ensure they stack evenly.
  • Place a small amount of frosting on the center of your cake stand or serving plate.Place one layer of the cake on the prepared cake stands or plate.
  • Using an offset spatula or butter knife, spread a generous layer of frosting (at least 5-6 scoops) evenly over the top of the first cake layer. Smooth it out to ensure an even surface.
  • Carefully place the second cake layer on top of the frosted first layer. Align it as evenly as possible.
  • Apply a crumb coat by spreading a thin layer of frosting over the entire cake. This layer seals in any crumbs and creates a smooth surface for the final coat. Chill the cake in the refrigerator for about 30 minutes.
  • After the crumb coat has been set, apply the final layer of frosting. Smooth it out with the offset spatula.
  • For a clean finish, you can use a bench scraper to smooth the sides.
  • If desired, use a piping bag to pipe rosettes or borders, to the top and sides of the cake.
  • Refrigerate the assembled cake for at least 30 minutes to allow the frosting to set and make slicing easier.
  • Once the cake is chilled and the frosting is set, remove it from the refrigerator and let it come to room temperature for about 10-15 minutes before serving. This allows the flavors to fully develop.

Notes

  • Cup vs weighing scale: The US customary cup measurement serves as a rough estimate, as it can have uncertainties, so for precise results, it's recommended to weigh your ingredients using a digital scale in grams
  • Before you start to make any recipe, measure and prepare your ingredients so the process will go smoothly and easily.
  • For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons and not the type of spoons you eat with for accuracy.
  • Milk: You can use any dairy-free unsweetened milk (like almond, soy, oat) or dairy-based whole milk.
  • Butter: Dairy-free butter sticks or any butter of your choice.
  • Lemon Juice: You can substitute with Apple Cider Vinegar / White Vinegar and vice-versa.
  • Whipping Cream: Use Dairy-free unsweetened whipping cream for a vegan version or any full-fat whipping cream of your choice.
  • Sugar: Cane sugar can be substituted with granulated sugar or castor sugar. Ensure the sugar is vegan-friendly (some sugars are processed with bone char) or use organic cane sugar.
