Step 1: Prepare the cream cheese layer. In a large mixing bowl, using an electric mixer, beat the softened cream cheese with the granulated sugar until the mixture is light, fluffy, and smooth, ensuring no lumps remain. This creates the rich base for this luscious layer. Gently fold in half of the thawed whipped topping until just combined. Be careful not to overmix, as you want to maintain the airiness of the whipped topping. Set this delectable mixture aside.
Step 2: Prepare the pudding layer. In a separate large bowl, whisk together the two packages of instant vanilla pudding mix with the 4 cups of cold milk. Whisk continuously for exactly 2 minutes, or until the mixture begins to visibly thicken. It’s important to use cold milk for the pudding to set correctly. Allow the pudding to sit for an additional 2-3 minutes to become fully set and firm. This perfectly prepared pudding is a key component of your banana pudding lasagna.
Step 3: Assemble the first layer of vanilla wafers. Take your 9×13 inch baking dish and arrange a single, even layer of vanilla wafers at the very bottom. You may need to break some wafers into smaller pieces to fill any gaps and ensure the entire bottom of the dish is covered snugly. This forms the essential base of your banana pudding lasagna.
Step 4: Add the banana slices. Evenly place half of your freshly sliced ripe bananas over the layer of vanilla wafers. Try to distribute them as uniformly as possible so every slice of banana pudding lasagna gets a good portion of fruit.
Step 5: Spread the cream cheese mixture. Carefully and gently spread the entire cream cheese and whipped topping mixture that you prepared in Step 1 over the layer of banana slices. Use an offset spatula or the back of a spoon to create an even layer, being mindful not to disturb the bananas beneath. This creates a wonderfully rich and creamy layer that makes this banana pudding lasagna truly special.
Step 6: Add more wafers and bananas. Place another complete layer of vanilla wafers directly over the cream cheese mixture. Following that, top with the remaining half of your sliced bananas. Again, aim for even distribution to ensure a balanced flavor profile throughout your banana pudding lasagna.
Step 7: Add the pudding. Now, pour the thickened vanilla pudding, prepared in Step 2, evenly over the banana layer. Gently spread the pudding with your spatula to cover all the bananas and wafers completely, creating a smooth and uniform surface. This step seals in the creamy goodness of your banana pudding lasagna.
Step 8: Top with whipped topping. Spread the remaining half of the thawed whipped topping over the pudding layer. Make sure it’s spread smoothly and evenly across the entire surface of your banana pudding lasagna. This final layer adds a light, airy finish.
Step 9: Chill and garnish. Cover the assembled dish tightly with plastic wrap. It’s crucial to refrigerate your banana pudding lasagna for at least 4-6 hours. However, for the absolute best results, allowing it to chill overnight will let the flavors meld perfectly and the wafers to soften to that ideal cake-like texture. Just before serving, you can garnish your stunning banana pudding lasagna with extra crushed vanilla wafers, fresh banana slices, or a few whole wafers for visual appeal. Once set, this banana pudding lasagna stores beautifully. For easy cleanup and freshness, I highly recommend using durable Basics Glass Food Storage containers.
