Follow these simple steps to create your delicious Strawberry Icebox Cake:

1. Prepare the Cream: In a large bowl, whip the heavy cream until soft peaks form. Gradually add the powdered sugar and vanilla extract, then continue whipping until firm peaks form.
2. Set Up for Layering: Select a 9×13 inch dish or a springform pan for assembling your cake.
3. Layer Graham Crackers: Start by placing a layer of graham crackers at the bottom of the dish. Let them overlap slightly for full coverage.
4. Add Cream: Spread a layer of the whipped cream mixture over the graham crackers, ensuring it’s evenly distributed.
5. Layer Strawberries: Add a layer of sliced strawberries over the cream, making sure to cover as much surface area as possible.
6. Repeat Layers: Alternate between layers of graham crackers, cream, and strawberries until you reach the top of your dish. Finish with a layer of whipped cream.
7. Chill: Cover the dish with plastic wrap and refrigerate for at least 4 hours or overnight. This chilling time is crucial for the graham crackers to soften and absorb flavors.
8. Serve: Once chilled, remove from the fridge and garnish with additional strawberries if desired before slicing.
9. Enjoy: Cut into squares or wedges and serve immediately.

This method will yield a delightful Strawberry Icebox Cake that looks as good as it tastes!
