Cake Ingredients
- 1 1/3 cups granulated sugar
- 2 cups sifted all-purpose flour
- 1/2 teaspoon salt
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 3-ounce package lime flavored gelatin
- 5 large eggs, slightly beaten
- 1 1/2 cups vegetable oil
- 3/4 cup orange juice
- 1 tablespoon lemon juice
- 1/2 cup key lime juice (about 2–3 key limes or 4 regular limes)
- 1/2 teaspoon vanilla extract
Cream Cheese Lime Icing
- 1 stick (1/2 cup) butter, room temperature
- 1 8-ounce package cream cheese, room temperature
- 5 cups confectioner’s sugar
- 1 tablespoon key lime juice
- 1 teaspoon vanilla extract
- 4 drops green food coloring
- 2 tablespoons lime zest
- Preheat and Prepare Pans: Preheat the oven to 350°F (175°C). Grease and flour three 9-inch round cake pans to prevent sticking and ensure even baking.
- Mix Dry Ingredients: In a large mixing bowl, combine the granulated sugar, sifted all-purpose flour, salt, baking powder, baking soda, and lime flavored gelatin. Mix thoroughly to evenly distribute all dry components.
- Combine Wet Ingredients: In a separate medium bowl, whisk together the slightly beaten eggs, vegetable oil, orange juice, lemon juice, key lime juice, and vanilla extract until well blended.
- Incorporate Wet with Dry: Add the wet ingredients mixture to the dry ingredients bowl and stir gently until just combined to avoid overmixing, which could affect cake texture.
- Divide Batter and Bake: Pour the batter evenly into the prepared cake pans. Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean, indicating the cake is fully baked.
- Cool Cakes: Let the cakes cool in their pans for 10 minutes to settle, then turn them out onto wire racks to cool completely before frosting.
- Prepare Icing Base: In a mixing bowl, beat the room temperature butter and cream cheese together until smooth and creamy to form the base of the icing.
- Add Remaining Icing Ingredients: Gradually add the confectioner’s sugar to the butter-cream cheese mixture while continuing to beat. Then mix in the key lime juice, vanilla extract, green food coloring, and lime zest until frosting is evenly creamy and vibrant.
- Assemble and Frost Cake: Once the cakes are completely cooled, frost the layers with the cream cheese lime icing. Stack the cakes carefully and apply additional frosting on top and sides as desired for a smooth finish.
Notes
- Allow cakes to cool completely before frosting to prevent the icing from melting.
- If key limes are unavailable, regular limes can be used but will alter the flavor slightly.
- To avoid clumps in the icing, sift the confectioner’s sugar before adding.
- Adding green food coloring is optional and mainly for aesthetic appeal.
- You can prepare the cake layers a day ahead and refrigerate them wrapped tightly; frost just before serving.
