01 - Line a 9-inch springform pan with parchment paper to ensure easy removal later.
02 - In a medium bowl, combine crushed cookies, melted butter, and granulated sugar. Mix until evenly moistened and all crumbs are coated.
03 - Press half of the crumble mixture firmly into the bottom of the prepared pan to form an even crust. Place in the freezer for 10 minutes to set.
04 - In a separate bowl, combine chopped strawberries and strawberry jam. Stir thoroughly to coat the strawberries evenly.
05 - Spread half of the softened vanilla ice cream over the chilled crust, using a spatula to create an even layer.
06 - Spoon the strawberry mixture evenly over the ice cream layer, distributing as uniformly as possible.
07 - Top with the remaining ice cream, smoothing the top with a spatula to create a flat surface.
08 - Sprinkle the remaining crumble evenly over the top and gently press to adhere to the ice cream.
09 - Cover with plastic wrap and freeze for at least 4 hours, or until completely firm throughout.
10 - Before serving, whip the heavy cream with powdered sugar and vanilla extract until stiff peaks form.
11 - Release the cake from the springform pan, top generously with whipped cream, and garnish with extra fresh strawberries if desired. Slice immediately and serve.
