How to Make Lemon Orange Rainbow Cake

  1. Preheat oven to 350°F (175°C). Grease and flour a 13x9 inch baking pan.
  2. In a large bowl, whisk together 2 large eggs, 1/2 cup vegetable oil, and 1 cup water.
  3. Beat with an electric mixer on medium speed until light and frothy (about 2 minutes).
  4. Add 1 box (15.25 oz) lemon-flavored cake mix and beat on low speed until just combined. Then, beat on medium speed for 2 minutes.
  5. Pour batter into the prepared pan and bake for 35-40 minutes, or until a wooden toothpick inserted into the center comes out clean.
  6. Let the cake cool in the pan for 15 minutes.
  7. Meanwhile, in a small bowl, dissolve 1 (3 oz) package orange Jell-O in 1 cup boiling water.
  8. Stir in 1/2 cup cold water until completely dissolved.
  9. Gently prick the cooled cake all over with a fork, going about three-quarters of the way down.
  10. Using a spoon, carefully pour about 1 tablespoon of the Jell-O mixture into each fork prick.
  11. Pour the remaining Jell-O mixture evenly over the top of the cake.
  12. Refrigerate, covered, for at least 2 hours to allow the Jell-O to set.
  13. Frost with 1 (8 oz) container of Cool Whip.
  14. Chill, covered, for another 2 hours before serving.
