A special summer memory is sharing this cake with neighbors after an afternoon in the garden. It always brings smiles.

Storage Tips

Keep the cake tightly covered in the refrigerator and it will keep well for three to four days. Graham crackers soften with time but the cake remains delicious and creamy. For travel a sturdy container with a tight lid is best to preserve the frosting’s smooth finish.

Ingredient Substitutions

If you cannot find instant lemon pudding mix try instant cheesecake or vanilla pudding and add lemon zest for that citrus brightness. Whipped topping can be substituted with homemade whipped cream if you prefer fresh ingredients just fold gently to keep airiness. For a vegan option choose plant-based milk and nondairy whipped topping and frosting brands labeled vegan.

Serving Suggestions

Serve chilled with fresh berries or a drizzle of raspberry sauce for contrasting flavor and color. Pair this dessert with a light herbal tea or sparkling water with lemon slices for a refreshing finish to a meal. Add a few lemon zest curls on top for a zesty garnish that gives sparkle and aroma to each bite.
