How to Make Fruity Pebbles Icebox Cake

Creating this delightful dessert is as easy as pie—or rather, cake! Follow these simple steps to bring this masterpiece to life:

Prepare the Mousse: In a medium mixing bowl, whisk together the Jell-O vanilla pudding mix and cold milk. Blend until the mixture thickens into a luscious, creamy mousse. Gently fold in half of the thawed Cool Whip until just combined, creating a light, fluffy texture.
Layer the Graham Crackers: Line the bottom of your 9×13 glass baking dish with a single layer of Honey Maid Graham Crackers, ensuring they sit closely together.
Add the First Layer: Spread half of the vanilla mousse over the graham crackers, using a spatula to create an even layer. Then, generously sprinkle Post Fruity Pebbles Cereal over the mousse, ensuring every bite bursts with flavor.
Repeat the Process: Add another layer of graham crackers on top of the Fruity Pebbles. Spread the remaining mousse over this layer, followed by the rest of the Cool Whip. Don’t skimp on the decoration—sprinkle a hearty layer of more Fruity Pebbles on top.
Chill and Set: Cover the dish with plastic wrap and refrigerate overnight. This step is crucial; it allows flavors to meld and the cake to achieve its ideal creamy consistency.
