Rainbow Citrus Cake Recipe

Tri-colored cake with a lemon layer, lime layer and an orange layer. The filling is a lemon curd and the frosting is orange.


3 1/2 cups all-purpose flour                                                2 teaspoons grated lemon zest

5 teaspoons baking powder                                                2 teaspoons grated orange zest

1 teaspoon salt                                                                       2 teaspoons grated lime zest

3/4 cup shortening                                                               2 drops yellow food coloring

2 1/4 cups white sugar                                                         2 drops orange food coloring

4 eggs, room temperature                                                   2 drops green food coloring

1 1/2 cups milk                                                                       1 recipe Lemon Custard Filling

2 teaspoons vanilla extract                                                  1 recipe Orange Cream Frosting


  1. Preheat oven to 350 degrees F (175 degrees C). Grease and flour three 9-inch pans. Sift together the flour, baking powder, and salt. Set aside.
  2. In a large bowl, cream together the shortening and sugar until light and fluffy. Beat in the eggs one at a time, mixing until each egg is incorporated; stir in the vanilla. Beat in the flour mixture alternately with the milk. Divide batter into 3 bowls.
  3. In the first bowl, stir in lemon zest and yellow food coloring; pour into prepared pan. In the second bowl, stir in orange zest and orange food coloring; pour into second prepared pan. In the last bowl, stir in the lime zest and green food coloring; pour into third prepared pan.
  4. Bake in the preheated oven until a toothpick inserted into the center of each cake layer comes out clean, about 30 minutes. Let cool in pan for 5 minutes, then turn out onto a wire rack and cool completely.
  5. Assemble the cake: stack the layers together with the Lemon Filling in between the layers. Frost sides and top with Orange Cream Frosting. Refrigerate until serving.
