Instructions
Step 1: Bake the Cake Layers
Prepare the Funfetti cake mix according to package instructions.
Bake the cake in a 9×13-inch pan or on a baking sheet for a thinner layer.
Let the cake cool completely.
Once cooled, slice the cake horizontally into thin layers or crumble into large pieces.
Step 2: Make the Pudding Layer
In a bowl, whisk together the vanilla pudding mixes and cold milk until thickened (about 2 minutes).
Set aside.
Step 3: Make the Cream Cheese Layer
In another bowl, beat softened cream cheese with powdered sugar and vanilla extract until smooth.
Fold in one container of whipped topping and a handful of rainbow sprinkles.
Step 4: Assemble the Lasagna
Layer 1: Place a layer of cake pieces or a thin cake slice at the bottom of the baking dish.
Layer 2: Spread half of the cream cheese mixture over the cake.
Layer 3: Spread half of the vanilla pudding over the cream cheese layer.
Layer 4: Repeat with another layer of cake, the rest of the cream cheese mixture, and the rest of the pudding.
Layer 5: Top with the second container of whipped topping.
Step 5: Decorate
Sprinkle generously with rainbow sprinkles and extra fun toppings if desired.
Step 6: Chill
Cover and refrigerate for at least 4 hours, preferably overnight, to allow the layers to set.
Step 7: Slice & Serve
Slice into squares and serve chilled.
Notes
Let the Cake Cool Completely – Prevents melting the cream layers.
Chill Overnight – Makes slicing clean and neat, and the flavors meld beautifully.
Use Plenty of Sprinkles – Adds the signature funfetti look and feel.
Fold Gently – When mixing whipped topping into the cream cheese layer to keep it light and fluffy.
Customize It – Add crushed cookies, extra candies, or drizzle with melted white chocolate.
