Instructions
 

Preparation

  • Preheat the oven to 350°F (175°C) and grease and line two 8-inch round pans.
  • In a bowl, whisk together the flour, baking powder, and salt.
  • Cream the butter and sugar in a stand mixer on medium-high until pale and fluffy (about 3–4 minutes).
  • Add eggs one at a time, scraping the bowl between additions, then stir in the vanilla.
  • With the mixer on low, alternately add the flour and milk until fully combined.

Baking

  • Divide batter evenly between pans and bake for 24–28 minutes or until a toothpick comes out with a few moist crumbs.
  • Let sit for 10 minutes, then turn out to cool completely on a rack.

Buttercream Preparation

  • In a mixing bowl, beat the butter until smooth, then gradually add powdered sugar.
  • Add milk, vanilla, and salt, beating to desired spreadable consistency.

Assembly

  • Level cakes if domed, then place the first layer on a cake board, pipe a buttercream ring, and fill with buttercream.
  • Top with the second layer.
  • Apply a thin crumb coat and chill for 20–30 minutes.
  • Apply a final smooth layer of buttercream, then prepare ganache and pour over chilled cake edges for the drip effect.
  • Decorate with sprinkles and fondant shapes, then chill until set.
