Creating the Summer Berry Jello Lasagna can be a straightforward process if you follow these steps:

1. Prepare the Crust: In a bowl, mix the graham cracker crumbs, melted butter, and granulated sugar until well combined. Press the mixture into the bottom of a 9×13-inch baking dish to form a crust.

2. Make the Cream Cheese Layer: In another bowl, beat the softened cream cheese and powdered sugar together until smooth. Fold in the whipped topping until well blended. Spread this mixture over the graham cracker crust evenly.

3. Prepare the Berry Layer: In a medium bowl, dissolve the strawberry gelatin in 1 ½ cups of boiling water. Stir until fully dissolved and let it cool for a few minutes.

4. Add the Berries: In the now-cooled gelatin, gently fold in the mixed fresh berries. Pour this mixture over the cream cheese layer in the baking dish.

5. Chill: Cover the dish and refrigerate for 4-6 hours or until fully set. For best results, chilling overnight allows the flavors to meld beautifully.

6. Add the Final Layer: Once set, spread the remaining whipped topping over the jello-berry layer to create a creamy finish.

7. Garnish: Decorate with additional fresh berries on top for an eye-catching presentation.

8. Serve: Cut into squares and serve chilled. Enjoy the refreshing layers and delightful flavors!
