Creating the Lemon Coconut Icebox Cake is a straightforward process that doesn’t require any baking. Follow these simple steps to assemble your cake:

1. Prepare the Mixture: In a mixing bowl, combine the coconut whipped topping, lemon yogurt, lemon juice, lemon zest, and shredded coconut. Mix until well combined to form a smooth, creamy mixture.
2. Layer the Base: Take a suitable dish and arrange a layer of graham crackers at the bottom. Ensure the crackers cover the base evenly.
3. First Layer of Filling: Spread half of the lemon coconut mixture over the graham crackers, ensuring an even layer.
4. Repeat Layers: Add another layer of graham crackers on top of the mixture. Then, spread the remaining lemon coconut mixture over this second layer of graham crackers.
5. Top It Off: Optionally, sprinkle more shredded coconut on top for added texture and flavor.
6. Refrigerate: Cover the dish with plastic wrap or a lid and refrigerate for at least 4 hours. For best results, let it chill overnight. This allows the flavors to meld and the texture to firm up.
7. Serve: Once chilled, slice the cake and serve it cold, garnished with fresh lemon slices if desired.
