serves 24


  • 2 cups Simple Truth Organic Unsalted Butter, at room temperature
  • 2¾ cups granulated sugar
  • 2 teaspoon salt
  • 8 egg whites
  • 1 tablespoon plus 1 teaspoon vanilla extract
  • 1¾ cups milk
  • 2 tablespoons apple cider vinegar
  • 1 tablespoon plus 1 teaspoon baking powder
  • 2 tablespoons cornstarch
  • 4 cups plus 2 tablespoons all-purpose flour
  • Gender-colored candy


  • 4 cups (2 pounds, 8 sticks) unsalted butter, at room temperature
  • 7½ cups (2 1-pound boxes) powdered sugar, sifted
  • 4 tablespoons half-and-half or whole milk
  • 1 tablespoon vanilla
  • 1 teaspoon salt


  1. Preheat oven to 325℉.
  2. Combine milk and vinegar, then
    set aside.
  3. In a large bowl, cream butter
    and sugar until light and fluffy. Add whites slowly, making sure to mix
    thoroughly before adding more.
  4. Add the milk mixture slowly.
    Mixture will look curdled by the end.
  5. In a large bowl, sift flour,
    baking powder, cornstarch, and salt.
  6. Add flour mixture in thirds and
    mix well until fully incorporated.
  7. Pour batter into greased, lined
    9 x 13–inch cake pans. Bake 45–55 minutes until a toothpick comes out
  8. Allow cakes to cool completely
    and freeze 30 minutes before trimming and leveling the cakes (if needed).
  9. Prepare the frosting: Using a
    hand mixer, cream the butter until light and fluffy. Add 1 cup of powdered
    sugar at a time and mix well before adding the next cup. Add the vanilla
    and salt. Mix well, then add the rest of the powdered sugar and continue
    to mix. Add ¾ of the milk and beat well. Add remaining milk if the
    frosting is too thick.
  10. Once the cakes are cooled and leveled,
    begin building.
  11. With a simple template, cut off the
    onesie collar and leg holes on both cakes. Reserve the leg-hole cuts to
    make sleeves.
  12. On the bottom layer, hollow out
    the center of the cake, being careful not to cut more than halfway. Crumb
    coat the entire layer and spread enough frosting for the center of the
    cake. Set in refrigerator to chill. For the top layer, cut the same hole,
    but this time all the way through. Take the center cut out and cut in half
    horizontally. Save the top half for a “lid.” Top the cake with the second
    layer. Crumb coat the cut lid and hollowed-out portion of the cake.
  13. When everything is set, begin
    building cake. Fill with gender candy. Place cake lid to seal the candy.
  14. Take reserved cake for the
    sleeves and build them on the sides. Crumb coat the entire cake and place
    in refrigerator for 30 minutes.
  15. Finish cake with remaining buttercream
    and decorate! Allow to cool for at least 30 minutes before serving and
