- 4 eggs, room temperature
- 1 1/2 cups milk

Instructions
1
Preheat your oven to 350 degrees Fahrenheit, or 175 degrees Celsius.
2
Next, take a pastry brush and grease three 9-inch round cake pans thoroughly. Then, dust them lightly with flour to prevent sticking.
3
In a separate bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, and a pinch of salt. Set this mixture aside for now.
4
In a large mixing bowl, use an electric mixer to cream together 1 cup of shortening and 1 cup of granulated sugar until they become light, fluffy, and well combined.
5
Crack in 2 eggs one at a time, mixing each egg thoroughly until it's fully incorporated; then stir in 1 teaspoon of vanilla extract.
6
Gradually add the flour mixture to the wet ingredients, alternating with 1 cup of milk until just combined.
7
Divide this batter evenly into three separate bowls.
8
In the first bowl, add 1 tablespoon of lemon zest and a few drops of yellow food coloring; pour the batter into your prepared pans.
9
In the second bowl, add 1 tablespoon of orange zest and a few drops of orange food coloring; pour the batter into your second prepared pan.
10
In the last bowl, add 1 tablespoon of lime zest and a few drops of green food coloring; pour the batter into your third prepared pan.
11
Bake these cakes in a preheated oven for about 30 minutes, or until a toothpick inserted into the center of each cake layer comes out clean.
12
After baking, let these cakes cool in their pans for 5 minutes before transferring them to a wire rack to cool completely.
13
Now, it's time to assemble the cake: stack these layers together with a delicious Lemon Filling in between each layer.
14
Frost the sides and top of this cake with a generous helping of Orange Cream Frosting.
15
Refrigerate the entire cake until it's ready to be served.
