Ingredients

Scale

  • ½ tsp baking soda

  • ½ tsp salt

  • 1 cup granulated sugar

  • ½ cup butter (softened)

  • 3 large eggs

  • 1 cup milk or buttermilk

  • 1 tsp vanilla extract

Buttercream Frosting

  • 1 cup unsalted butter (room temp)

  • 4 cups powdered sugar

  • 23 tbsp milk or cream

  • 1 tsp vanilla extract

  • Food coloring (pink, lavender, etc.)

Fondant & Decorations

  • Fondant (white and colored)

  • Edible glitter

  • Sprinkles

  • Fondant flowers or molds

  • Barbie doll (cleaned and prepped)

  • Optional: luster dust, shimmer spray


Instructions

  1. Preheat Oven to 350°F (175°C). Grease and flour dome-shaped and round cake pans.

  2. Make Cake Batter:

    • In one bowl, whisk flour, baking powder, baking soda, and salt.

    • In another bowl, cream butter and sugar until light. Add eggs one at a time. Stir in vanilla.

    • Gradually mix in dry ingredients and milk. Don’t overmix.

  3. Bake Cakes:

    • Pour into pans and bake for 30–40 minutes. Test with a toothpick.

    • Let cool on a wire rack completely before shaping.

  4. Level & Shape Cake:

    • Stack and carve cakes into a dome to mimic a ball gown.

    • Hollow out the center slightly to insert the Barbie.

  5. Apply Crumb Coat:

    • Spread a thin layer of buttercream over the cake. Chill for 15–20 minutes.

  6. Final Frosting:

    • Add a thicker layer of buttercream. Use a turntable and spatula for smooth finish.

    • Pipe ruffles or patterns with colored frosting.

  7. Fondant Details:

    • Roll and cut fondant for bows, flowers, ruffles. Attach with buttercream or edible glue.

    • Drape fondant accents around the skirt for elegance.

  8. Add Barbie Doll:

    • Insert clean doll into the center. Wrap the legs with plastic if needed.

    • Pipe or dress the upper bodice with buttercream or fondant.

  9. Decorate:

    • Add edible glitter, shimmer spray, and fondant flowers. Customize based on party theme.

Notes

  • Use a dense cake like vanilla pound or sponge to ensure the structure holds.

  • If your Barbie is too tall, remove the legs or use a mini doll.

  • Chill buttercream for a firmer texture before piping.

  • Add supports if cake feels unstable (wooden dowel or straw).
