Ingredients

Scale
  • 1 box (15.25 oz) yellow cake mix
  • 1 cup cold water
  • 1/2 cup vegetable oil
  • 3 large eggs
  • 1 package (3 oz) orange gelatin mix
  • 1/2 cup boiling water
  • 1/2 cup cold water
  • 1 cup heavy whipping cream
  • 1 cup powdered sugar
  • 1 teaspoon vanilla extract
  • 1/4 cup fresh orange juice
  • Orange zest for garnish (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  2. Prepare the cake batter according to the package directions, substituting the required water with 1 cup of cold water. Mix well until just combined.
  3. Divide the batter evenly between the prepared pans. Bake for 28 to 32 minutes, or until a toothpick inserted into the center comes out clean.
  4. While the cakes cool slightly in the pans, prepare the orange gelatin. Dissolve the orange gelatin mix in the 1/2 cup of boiling water. Stir until fully dissolved.
  5. Add the 1/2 cup of cold water to the gelatin mixture and stir. Set aside to cool to room temperature, about 20 minutes.
  6. Once the cakes are cool enough to handle, poke holes all over the top of each cake layer using a fork or skewer, spacing them about 1 inch apart.
  7. Slowly pour half of the cooled orange gelatin mixture evenly over the top of each cake layer. Allow the cakes to absorb the gelatin completely, about 30 minutes.
  8. Prepare the vanilla frosting. In a large bowl, beat the heavy whipping cream, powdered sugar, and vanilla extract until stiff peaks form. Gently fold in the fresh orange juice until just combined, creating a creamy vanilla orange frosting.
  9. Place one gelatin-soaked cake layer on a serving plate. Spread about one-third of the frosting over the first layer.
  10. Top with the second cake layer. Frost the top and sides of the entire cake with the remaining frosting.
  11. Chill the cake for at least 1 hour before slicing. Garnish with orange zest if desired.

Notes

  • For an even more intense citrus flavor, you can substitute the cold water in the cake batter with orange soda.
  • If you prefer a poke cake style, use a 9×13 inch pan and pour all the gelatin mixture over the entire cake after baking. Top with the frosting after chilling.
  • This cake is best served cold to maintain the structure of the creamy frosting.
