Ingredients

Scale
  • 2 ½ cups all-purpose flour
  • 2 ½ cups sugar
  • 1 ¼ cups unsweetened cocoa powder
  • 2 ½ tsp baking powder
  • 2 ½ tsp baking soda
  • 1 ¼ tsp salt
  • 2 large eggs
  • 1 ¼ cups whole milk
  • 1 ¼ cups vegetable oil
  • 2 ½ tsp vanilla extract
  • 1 ¼ cups boiling water
  • 1 cup unsalted butter, softened
  • 4 cups powdered sugar
  • ½ cup unsweetened cocoa powder
  • ¼ cup heavy cream
  • 1 tsp vanilla extract
  • pinch of salt
  • 3 lbs white fondant
  • gel colors (blue, purple, pink, and gold for accents)
  • cornstarch (for dusting)
  • 1 cup sugar
  • ½ cup water
  • 1 tsp food-grade flavoring (e.g., vanilla or almond)
  • food coloring (optional)

Instructions

  1. Preheat the oven to 175 °C (350 °F) and prepare two round cake pans (20 cm diameter) by greasing them with butter and dusting with flour.
  2. In a large bowl, combine the flour, sugar, cocoa powder, baking powder, baking soda, and salt. This should take about 2 minutes.
  3. Add the eggs, milk, vegetable oil, and vanilla extract, and mix everything at medium speed for about 2-3 minutes until the batter is smooth.
  4. Carefully pour the boiling water into the batter and stir until everything is well combined. The batter will be thin.
  5. Evenly distribute the batter between the two prepared cake pans and bake for 30-35 minutes, until a toothpick comes out clean.
  6. Let the cakes cool in the pans for about 10 minutes before inverting them onto a wire rack to cool completely.
  7. Meanwhile, prepare the buttercream: Beat the softened butter in a large bowl until creamy, about 1-2 minutes.
  8. Add the powdered sugar and cocoa powder, mixing on low speed until well combined. Add the heavy cream, vanilla extract, and a pinch of salt, and continue beating until the mixture is fluffy and light (about 3-5 minutes).
  9. Once the cakes are completely cooled, trim the tops to create a flat surface. Place one cake on a cake plate and spread a layer of buttercream on top.
  10. Place the second cake on top and cover the entire cake with a thin layer of buttercream to catch crumbs. Refrigerate the cake for 30 minutes.
  11. Prepare the fondant: Knead the fondant with some cornstarch to make it pliable. Color it with the gel colors to create a marbled effect.
  12. Roll out the fondant on a lightly dusted surface and cover the cake with it, smoothing it gently.
  13. Cut out a piece for the geode effect and add the crystal sugar stones that you made earlier. Let your creativity shine!

Nutrition

Keywords: A common mistake is decorating the cake too early. Ensure the buttercream is well chilled for better fondant adherence. For fondant decoration, a smooth surface is crucial; use a fondant smoother for a perfect finish. The ratios of butter to powdered sugar in the buttercream are important; start with less powdered sugar and add more as needed. When making crystal sugar stones, avoid stirring the mixture while cooking, as this can affect crystal formation. Use a small amount of gel color when tinting fondant, as it is very concentrated.
