Creating the No Bake Strawberry Lasagna is straightforward when you follow these simple steps:

1. Prepare the Base: In a medium bowl, combine graham cracker crumbs with melted butter. Mix until well combined.
2. Form the Crust: Press the graham cracker mixture evenly into the bottom of a 9×13 inch glass dish. Set aside.
3. Make the Cream Layer: In another bowl, beat the softened cream cheese until smooth. Gradually add the powdered sugar and vanilla extract, mixing until combined.
4. Fold in Whipped Topping: Gently fold in the whipped topping until fully mixed with the cream cheese mixture.
5. Layer the Cream: Spread half of the cream mixture over the graham cracker crust evenly.
6. Add Strawberries: Layer half of the sliced strawberries on top of the cream layer. If using, spoon on the strawberry pie filling over this layer for extra flavor.
7. Repeat Layers: Spread the remaining cream mixture over the strawberries. Then, top with the remaining sliced strawberries.
8. Chill: Cover the dish tightly with plastic wrap or foil and place in the refrigerator for at least 4 hours, or overnight.
9. Serve: Once chilled and set, slice the lasagna into squares and serve with additional strawberries on top, if desired.

These steps will guide you through making this crowd-pleaser with ease.
