Ingredients

For the Filling:

  • 2/3 cup sugar
  • 2 TBS all-purpose flour
  • 1 TBS corn starch
  • 1 cup fresh orange juice without pulp (from about 3 large or 4 medium oranges)
  • 2 large egg yolks
  • 2 TBS salted butter

For the Cake:

  • 2 1/4 cups all-purpose flour (101/8 oz.)
  • 2 1/2 tsps baking powder
  • 1 tsp salt
  • 1/3 cup salted butter
  • 1/3 cup sour cream
  • 4 tsps grated orange zest from about 2 large oranges
  • 1 1/2 cups sugar
  • 3 large eggs
  • 1 cup strained fresh orange juice (you can add the juice of a lemon if you'd like some more zing)

For the Italian Buttercream:

  • 4 large egg whites
  • 1 1/2 cups sugar
  • 1/3 cup water
  • 1 pinch kosher salt
  • 16 ounces unsalted butter (32 tablespoons) room temperature cut into 1-inch pieces
  • 1 tsp pure vanilla extract
  • 3 drops orange food coloring

Instructions

For the Filling

  1. Whisk together sugar, cornstarch and the flour in a heavy-based saucepan.

  2. Add the orange juice and egg yolks and whisk to combine.

  3. Put the saucepan over medium-high heat and cook, whisking constantly until the mixture boils.

  4. Cook while stirring constantly, the mixture will become thicker and clearer.

  5. Allow mixture to boil for 1 minute.

  6. Remove from the heat and stir in the butter.

  7. Transfer to a bowl, cover surface with plastic wrap and chill.

For the Cake:

  1. Preheat the oven to 350°F. Butter and flour 4 six inch cake pans

  2. Sift together the flour, baking powder, and salt.

  3. Cream together the butter, sour cream, and orange zest.

  4. Slowly add the sugar, mixing until the mixture is light and fluffy. Scrape down the sides of the bowl. Add the eggs, one at a time, mixing well between additions and scraping down the sides.

  5. Add the sifted dry ingredients alternately with the orange juice to the creamed mixture, beating well on low speed after each addition. Pour equal amounts of the batter into the two prepared cake pans. (I also use cake strips on my pans for more even baking.) Bake until a toothpick inserted in the middle comes out clean, about 22 min. Cool the cake layers in the pans for 10 min. and then loosen the layers by running a knife between the cake and the edge of the pan. Remove the layers from the pans and put them on a rack to continue cooling.

For the Buttercream:

  1. Beat the egg whites and 1/3 cup of sugar until soft peaks form.

  2. In a medium saucepan add the remaining sugar and 1/3 cup water then place on low heat.

  3. Stir constantly until sugar melts and becomes clear.

  4. Maintain at medium high heat until temperature reads 235-240F.

  5. Drizzle the sugar into the mixer immediately.

  6. Run mixer until meringue is body temperature. Add salt.

  7. Add room temperature butter into running mixer one piece at a time. Add vanilla

  8. Beat until butter is combined and mixture has reached a silky consistency.

  9. I used an 869 tip to pipe the dollops, froze them, and then placed them on top. I divided my buttercream into several batches and added varying amounts of food coloring to create an ombre effect.
