Units Scale

For the Cake

  • 3 cups cake flour
  • 1/2 tsp.salt
  • 2 tsp baking powder
  • 1/2 tsp baking soda
  • 3 cups sugar
  • 1 cup (2 sticks) butter, softened to room temperature
  • 7 large eggs, yolks removed, use egg whites only
  • 2 Tbsp. pure vanilla extract
  • 1 cup sour cream
  • 2 1/2 lbs strawberries

For The Italian Meringue Buttercream

  • I double this for a thicker frosting
  • 11/4 cups sugar
  • 2/3 cup water at room temperature
  • 7 jumbo egg whites
  • Pinch of cream of tartar
  • 2 cups unsalted butter at room temperature, cut into tablespoons
  • 1 tsp. pure vanilla extract


For The Cake

  1. Preheat oven to 325 degrees F.
  2. Butter and flour two 9-inch round cake pans or 3 8-inch round cake pans.
  3. In a medium bowl, whisk together flour, salt, baking powder, and baking soda.
  4. In a large bowl, cream butter and sugar together until light and fluffy.
  5. Add egg whites, one at a time, beating after each addition.
  6. Beat in vanilla.
  7. Add sour cream, and beat for 30 seconds.
  8. Add flour mixture in three additions, beating to blend after each addition.
  9. Divide batter into prepared pans.
  10. Bake cake until a toothpick inserted into the center comes out clean, 50-60 minutes.
  11. Remove from oven and cool for 10 minutes.
  12. Run a sharp knife around the edges of the pans, then turn cakes out onto a rack to cool completely.
  13. If using two 9-inch cakes, take a serrated knife, and slice each of the two cakes in half horizontally. If using three 8-inch cakes, as I did, there is no need to slice any of them in half.
  14. Place first layer of cake on a cake plate.
  15. Spread a thick layer of frosting over the first cake layer.
  16. Slice strawberries, leaving enough unsliced to decorate the cake.
  17. Arrange sliced strawberries all over the frosting in a single layer.
  18. Place the next cake layer on top and press down gently so that the strawberries are firmly set into the frosting.
  19. Frost this second cake layer and repeat laying sliced strawberries on top of the frosting.
  20. Repeat until the top cake is finally placed.
  21. Generously frost the entire cake on top and sides, beginning with spreading two cups of frosting over the top and sides of the cake in a thin layer, then frost with remaining frosting.
  22. This recipe makes a very big 4-layer cake or a thick 3-layer cake!

For The Italian Meringue Buttercream

  1. In a small saucepan over medium heat, bring sugar and water to a boil.
  2. Continue to boil until sugar syrup reaches 240 – 244 degrees F, soft-ball stage on a candy thermometer. As it cooks start step 2, the meringue.
  3. While sugar syrup is cooking, separate eggs placing whites in the bowl of an electric mixer fitted with the whisk attachment, and beat on low to medium speed until foamy.
  4. Add cream of tartar, and whip on medium to high speed until medium to stiff peaks form, but not dry.
  5. With mixer running, add cooked syrup to whites in a slow but steady stream, beating on high speed. Always be careful when working with hot sugar.
  6. Beat on high speed until steam from hot syrup stops, about 5 minutes.
  7. Add butter a tablespoon at a time, beating until smooth, approximately 4-5 minutes.
  8. Beat in vanilla, scrape down sides gently and beat again for 1 minute.


  • The cake is slightly altered from a recipe I found years ago in Bon Appetit magazine from which I scribbled the recipe down on a recipe card and so I don’t have the actual date of the issue. The Italian Meringue Buttercream is from the famous Italian “Cake Boss”. If he prefers this recipe for his famous cakes, then I knew that it would be a winner. It is certainly a winning recipe!
