Step 1: In a large mixing bowl, whisk together the instant cheesecake pudding mix and cold milk until the mixture thickens and becomes smooth. Make sure there are no lumps.
Step 2: Gently fold in the thawed whipped topping until it's fully combined with the pudding mixture. This creates an airy, creamy filling.
Step 3: Line the bottom of a 9x13-inch baking pan with a single layer of graham crackers, breaking them as needed to fit snugly and cover the entire bottom.
Step 4: Spread about one-third of the pudding mixture evenly over the graham cracker layer.
Step 5: Arrange a layer of sliced fresh strawberries over the pudding mixture.
Step 6: Repeat the layering process: add another layer of graham crackers, followed by another third of the pudding mixture, and then another layer of strawberries.
Step 7: Finish with a final layer of graham crackers, the remaining pudding mixture, and top generously with the remaining fresh strawberries for a beautiful presentation.
Step 8: Cover the pan tightly with plastic wrap and refrigerate for at least 6-8 hours, or preferably overnight, to allow the cake to set and the flavors to meld.
Step 9: Once thoroughly chilled, slice into squares and serve this cool, refreshing Strawberry Icebox Cake. Enjoy your delicious, homemade treat!
