Making Strawberry Icebox Cake is easy if you follow these simple steps:

1. Prepare the Cream Mixture: In a large bowl, combine the heavy whipping cream, powdered sugar, and vanilla extract. Use a handheld mixer to whip until soft peaks form.

2. Mix the Cream Cheese: In another bowl, beat the softened cream cheese until smooth and creamy.

3. Combine Creams: Gradually fold the whipped cream mixture into the cream cheese, being careful not to deflate the whipped cream.

4. Layer the Ingredients: Begin by spreading a thin layer of the cream mixture on the bottom of a 9×13 inch dish.

5. Add Graham Crackers: Layer graham crackers over the cream mixture until the bottom is covered.

6. Layer Strawberries: Add a layer of sliced strawberries over the graham crackers, followed by another layer of the cream mixture spread over the strawberries.

7. Repeat the Layers: Continue layering with graham crackers, strawberries, and cream mixture until all ingredients are used, finishing with a cream layer on top.

8. Chill: Cover and refrigerate the cake for at least 4 hours, or overnight for the best flavor and texture.

9. Serve: Before serving, garnish with extra strawberries if desired.
