Recipe Tips:

  • Level Cake –  If your cake is domed shaped once you bake it, level the cake with a serrated knife. This will help the layers to stack evenly.
  • Cool Cakes –  The layers need to cool completely before adding frosting or it will slide off.
  • Room temperature Ingredients – The frosting will combine smoother if the ingredients is room temperature.
  • Combining Ingredients –  Combine the cake ingredients until just combined. Mixing the ingredients excessively will make the cake dense instead of soft and fluffy.
  • Leave in Pans –  The cake needs to cool slightly before removing from the pan. This will help it to come out easier and not fall apart.
  • Food Coloring – You can add as much or as little food coloring as you prefer. The colors can be as vibrant or as faint as you desire.
  • Swirling Cake Batter – To make the fun pink and purple swirling colors in the cake.
