                Turn on your oven to 350°F (175°C). Use some grease or cooking spray on a 9×13-inch pan.

                Prepare the batter by following whatever steps are on the cake mix package. Stir in the eggs, oil, and water as instructed.

                Pour the mixture into the pan and bake as directed in the box's instructions. It usually takes around 25-30 minutes. Use a toothpick to test if it's done—poke it in, and if it comes out clean, you're good!
              
              
              
                04 - 
                After baking, leave the cake in the dish and let it sit for roughly 15 minutes so it cools a bit.

                Grab a wooden spoon handle or a fork and poke holes evenly throughout the cake. Keep about 1 inch between each hole.

                In two separate bowls, mix each flavor of gelatin with 1 cup of boiling water. Stir until it's dissolved completely.
              
              
              
                07 - 
                Carefully drizzle the gelatin mixtures across the cake. Alternate colors to give a nice marble-like pattern.
              
              
              
                08 - 
                Cover the cake and pop it in the fridge for at least a couple of hours so the gelatin sets properly.
              
              
              
                09 - 
                Spread out the whipped topping evenly across the top of the chilled cake.

                If you'd like to use coconut, add a few drops of food coloring to it and toss to color. Sprinkle over the cake.

                Finish by adding mini chocolate eggs, sprinkles, or any other festive topping you like.
