Preheat the oven to 350 degrees Fahrenheit. Prepare the cake mix in a large mixing bowl, with the eggs, water, and oil as listed on the box directions. Pour into a greased 9x13 pan, and bake in the oven according to package directions, or until a toothpick comes out clean. 15 oz White Cake Mix , eggs, water, and oil as listed on the box
Remove from the oven and let the cake cool for 30 minutes.
Bring 1 cup of water to boil in a small pot. Add the Lime Jello to a small bowl, and the Cherry to another. Pour 1/2 cup of hot water into each and stir until dissolved. 1 cup boiling water, 1.5 oz Lime Jello , 1.5 oz Cherry Jello
Add 1/4 cup of cold water to each bowl, and stir it in. 1/2 cup cold water
Poke holes all over the top of the cake using the bottom of a wooden spoon, a kabob stick, or a straw, about 1 inch apart from each other.
Carefully pour the liquid Jello into the holes, alternating red, and green, on every other hole. The easiest way to do this is with a squeeze bottle if you have one (or a straw with your finger suctioning the liquid up, works too).
Cover the cake and place it in the fridge for 2-3 hours.
Spread the Cool Whip over the top of the cooled cake evenly. Cover the cake again and place it in the fridge for another 1-2 hours, or overnight. 8 oz Cool Whip
Top with festive sprinkles and slice into pieces, and serve cake cold. Christmas sprinkles
