Ingredients
  

  • 3 cups all-purpose flour sifted
  • 2 ½ teaspoons baking powder
  • 1 teaspoons baking soda
  • ½ teaspoons salt
  • 1 cup unsalted butter softened
  • 2 cups granulated sugar
  • 4 large eggs room temperature
  • 1 tablespoon vanilla extract pure
  • 1 ¼ cups whole milk room temperature
  • As needed drops food coloring – pink pink, purple, etc.
  • 4 cups buttercream frosting – for filling and crumb coat
  • 1 pound fondant white, for covering
  • As needed sheets colored fondant for decorations
  • As needed teaspoons edible glitter optional
  • As needed pieces princess-themed toppers optional

Instructions
 

  • Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  • Mix dry ingredients: In a bowl, whisk flour, baking powder, baking soda, and salt.
  • Cream butter and sugar in a large bowl until light and fluffy. Add eggs one at a time, then mix in vanilla.
  • Alternate adding flour and milk, mixing until just combined. Add food coloring if desired.
  • Divide batter evenly between pans and bake for 40–45 minutes, or until a toothpick comes out clean. Let cool.
  • Level the cakes if needed. Layer with buttercream between each tier.
  • Cover the cake with buttercream to create a smooth surface.
  • Roll out fondant and drape it over the cake. Trim edges and smooth it out.
  • Decorate with edible glitter, fondant designs, and princess toppers.
  • Chill slightly before serving or display immediately at the party.

Notes

For best results, bake the cake layers a day in advance and chill them before decorating.
Use gel food coloring for more vibrant colors without thinning the batter.
A rotating cake stand makes decorating much easier and more precise.
Fondant can dry out quickly, keep unused portions wrapped in plastic.
To save time, you can use a boxed cake mix as the base and focus on custom decorations.
Store the finished cake in a cool place, ideally in the fridge if not served the same day.
Let the cake come to room temperature before serving for the best texture and flavor.
