Ingredients

For the Cake

  • 2 cups all-purpose flour
  • 1 tbsp baking powder
  • 1/2 tsp salt
  • 1 cup unsalted butter (softened)
  • 1 3/4 cups granulated sugar
  • 4 large eggs
  • 2 tsp vanilla extract
  • 1 cup whole milk
  • several drops yellow gel food coloring

For the Ganache

  • 1 cup heavy cream
  • 2 cups semi-sweet chocolate chips
  • several drops black gel food coloring

For the Frosting

  • 3 cups powdered sugar

Optional Decorations

  • additional decorations such as edible gold dust or themed cake toppers

Instructions

  1. Preheat and Prepare Pans. Preheat your oven to 350°F (175°C). Grease and flour three 8-inch round cake pans to prevent sticking.
  2. Mix Dry Ingredients. In a mixing bowl, whisk together the all-purpose flour, baking powder, and salt to ensure an even distribution of leavening agents.
  3. Cream Butter and Sugar. Beat the softened unsalted butter and granulated sugar on medium speed using a stand mixer until the mixture becomes light and fluffy.
  4. Add Eggs and Vanilla. Incorporate the eggs one at a time, beating well after each addition, then mix in the vanilla extract to infuse flavor.
  5. Combine Wet and Dry Ingredients. Gradually add the dry ingredients to the butter mixture alternated with whole milk, mixing just until combined without overmixing.
  6. Color the Batter. Add several drops of yellow gel food coloring to the batter and mix gently to achieve the signature Hufflepuff yellow color.
  7. Divide and Bake. Evenly divide the batter among the prepared cake pans and bake in the preheated oven for 25 minutes, or until a toothpick inserted in the center comes out clean.
  8. Prepare Ganache. Heat heavy cream in a small saucepan over medium heat until it begins to simmer. Pour the hot cream over the semi-sweet chocolate chips in a bowl. Let sit for a few minutes, then stir until smooth. Add black gel food coloring if desired and mix well.
  9. Cool and Level Cakes. Allow the cakes to cool completely. Use a serrated knife to level the tops for even stacking.
  10. Assemble Layers with Ganache. Stack the cake layers, spreading ganache evenly between each layer for a rich chocolate filling.
  11. Apply Crumb Coat. Frost the outside of the cake with a thin yellow buttercream crumb coat to seal in crumbs. Refrigerate for 30 minutes to set.
  12. Frost and Decorate. Apply a final smooth layer of yellow buttercream frosting over the cake. Drizzle the cooled ganache on top decoratively.
  13. Chill Before Serving. Chill the assembled cake for at least 30 minutes before slicing and serving to ensure clean cuts and set frosting.

Notes

  • For a dairy-free version, substitute vegan butter for unsalted butter, and plant-based milk for whole milk.
  • Flax eggs can be used as a vegan substitute for eggs by mixing 1 tbsp flaxseed meal with 3 tbsp water per egg.
  • Using fresh baking powder is essential for a good rise and fluffy texture.
  • When leveling cake layers, a serrated knife or cake leveler ensures even stacking and a professional finish.
  • Edible gold dust or themed cake toppers can enhance the Hufflepuff aesthetic and make the cake more festive.
  • Chilling the cake after crumb coating helps achieve a smoother final frosting layer.
  • Store leftover cake covered in the refrigerator for up to 3 days for freshness.
