  • 1 cup sugar
  • 1 egg + 2 eggs whites
  • 2 tbsp oil flavorless oil

  • 1/3 cup sprinkles

for the vanilla buttercream frosting

  • 1 cup unsalted butter room temperature
  • 3 1/2 cups powdered sugar
  • 1 tbsp vanilla extract
  • 3 tbsp milk


For the Cake

  • Preheat oven to 350 degrees. Grease two 8" cake pans and dust with flour. This will prevent the cake from sticking.
  • Combine all the dry ingredients in a medium bowl - flour, baking powder, and salt. Mix and set aside.
  • In a large bowl, cream butter until light and fluffy.
  • Add sugar and cream for a few minutes until the mixture is creamy and smooth.
  • Add one egg at a time, vanilla extract, and 2 tbsp oil. Mix well until it's all combined.
  • This is what you should have.
  • Add dry ingredients and milk in batches starting and ending with the dry ingredients. Mix, but do NOT over mix. Now begin by adding 1/3 of the dry ingredients.
  • Add 1/2 of the milk. Then add dry ingredients - milk - dry ingredients.
  • Result so far.
  • Add sprinkles. Mix the sprinkles in using a spatula. Do not over mix.
  • Batter is ready.
  • Split the batter evenly into 2 round baking trays. Into the oven for 25-30 minutes.
  • Cake is done. Let it completely cool before frosting.

For the Frosting

  • Add 2 sticks of room temperature butter to a large mixing bowl.
  • Using an electric mixer, cream until light and fluffy.
  • Add powdered sugar and mix well.
  • Add vanilla extract. Mix.
  • Now add milk. Mix. Frosting is ready.

Frost the cake - I did not frost the sides

  • Add a dollop of frosting to the cake stand.
  • Place one round cake on top - flat side up.
  • Top with half the frosting - so a very generous amount.
  • Place the second cake on top with the flat side facing up.
  • Top with a generous amount of frosting. Use a spoon to make some swirls.
  • Top with sprinkles and add some to the middle layer on the sides.

For Garnish

  • rainbow sprinkles, for the top and sides
