Preheat the oven to 350 degrees. Prepare a 9x13 baking dish with nonstick cooking spray.
1 15.25 oz box Funfetti cake mix
In a mixing bowl, beat the cake mix, melted butter, water, eggs, and vanilla until completely mixed, scraping down the sides as needed.
¾ cup butter, 3 tablespoons water, 2 eggs, 1 teaspoon vanilla
Transfer the cake batter to the prepared baking dish.
Bake for 20 to 25 minutes or until a toothpick inserted in the middle returns clean. Place the baking dish on a wire rack and allow the cake to cool completely.
Beat the cream cheese with the powdered sugar until smooth. Stir in ¼ cup sprinkles. Then, fold in 2 cups of the whipped topping. Spread the cream cheese mixture over the top of the cake.
1 8 oz pkg cream cheese, 1 cup powdered sugar
Next, whisk together the pudding mix and milk for 2 minutes or until it begins to thicken. Spread the pudding over the top of the cream cheese layer.
1 1.5 oz box instant vanilla pudding mix, 2 cups milk
Add a final layer with the remaining whipped topping and decorate with the remaining sprinkles.
Refrigerate for 2 hours prior to serving.
