Preheat and Prepare the Cake
Preheat the oven to 350°F (175°C) and grease a 9x13-inch baking dish.
Prepare the cake batter according to the package instructions.
Create the Swirls
Divide the batter evenly into four bowls.
Add a few drops of pink, purple, yellow, and light blue gel food coloring to each bowl and mix until vibrant.
Spoon the colored batters randomly into the prepared baking dish, then use a knife or skewer to gently swirl the colors together.
Bake the Cake
Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
Let the cake cool for about 10 minutes.
Poke the Cake & Add the Pudding
Use the handle of a wooden spoon to poke holes evenly across the cake.
In a medium bowl, whisk together the cheesecake pudding mix and milk until slightly thickened but still pourable.
Pour the pudding evenly over the cake, ensuring it fills the holes.
Chill & Add Toppings
Refrigerate for at least 2 hours to allow the pudding to set.
Spread the whipped topping evenly over the cake.
Decorate with Easter sprinkles or mini chocolate eggs.
Serve and Enjoy
Slice and serve chilled for the best texture and flavor.
