Ingredients

Scale

Main Ingredients (Cake Base):

  • 1 ¼ cups (160g) all-purpose flour
  • ½ cup (113g) unsalted butter, softened
  • ¾ cup (150g) granulated sugar
  • 2 large eggs, room temperature
  • ½ cup (120ml) whole milk, room temperature

Leavening and Seasoning:

  • 1 teaspoon baking powder
  • ¼ teaspoon salt
  • 1 teaspoon vanilla extract

Frosting Ingredients:

  • 1 cup (226g) unsalted butter, softened
  • 3 cups (360g) powdered sugar
  • 2 tablespoons heavy cream or milk
  • 1 teaspoon vanilla extract
  • 1 pinch of salt
  • Gel food coloring (optional)

Instructions

  1. Prepare the cake base by whisking flour, baking powder, and salt in a separate bowl, ensuring no lumps remain.
  2. Cream butter and sugar in a large mixing bowl until the mixture becomes pale and airy, which typically takes about 3 minutes of consistent beating.
  3. Incorporate eggs individually, thoroughly mixing after each addition to create a smooth, homogeneous batter.
  4. Gently fold in vanilla extract, maintaining the delicate texture of the mixture.
  5. Alternate adding dry ingredients and milk to the batter, beginning and concluding with the dry mixture. Mix until ingredients are just combined, avoiding overmixing.
  6. Transfer the batter into a greased and parchment-lined 9×13-inch baking pan, spreading evenly with a spatula to ensure uniform thickness.
  7. Bake in a preheated oven at 350°F (175°C) for approximately 20 minutes, checking doneness by inserting a toothpick into the center – it should emerge clean.
  8. Allow the cake to cool completely on a wire rack, which prevents condensation and maintains the cake’s structure.
  9. Whip butter until smooth and creamy, creating a perfect base for the buttercream frosting.
  10. Gradually incorporate powdered sugar, mixing on low speed to prevent sugar clouds and ensure a silky consistency.
  11. Enhance the frosting with heavy cream, vanilla extract, and a pinch of salt, beating until the mixture becomes light and fluffy.
  12. If desired, divide the frosting and add food coloring for decorative purposes.
  13. Use a round cookie cutter to delicately extract individual cake layers from the cooled sheet cake.
  14. Construct mini cakes by layering cake rounds with thin frosting intervals, creating a delicate tower.
  15. Apply a preliminary crumb coat to seal in loose cake particles, then refrigerate briefly to set.
  16. Frost the entire mini cake smoothly, creating a polished exterior.
  17. Embellish with piped buttercream designs or personalized messages.
  18. Carefully place each mini cake in a parchment-lined takeout box for a charming presentation.
  19. Refrigerate for 30 minutes to firm up the frosting and maintain structural integrity before serving.

Notes

  • Achieve smooth cake texture by ensuring all ingredients are at room temperature before mixing, which helps create a more uniform batter and prevents lumps.
  • Prevent dry cake by carefully measuring flour and not overmixing the batter, as excess mixing can develop gluten and lead to a tough, dense result.
  • Customize frosting consistency by adjusting heavy cream amount – less cream creates stiffer frosting for detailed piping, while more cream makes it softer and spreadable.
  • Create gluten-free version by substituting regular flour with a 1:1 gluten-free baking blend, maintaining the same measurements and mixing technique.
