01 - Line a 9-inch springform pan with parchment paper to prevent sticking and ensure easy removal.
02 - Combine crushed cookies, melted butter, and granulated sugar in a medium bowl. 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. Freeze for 10 minutes to set.
04 - In a separate bowl, combine chopped strawberries and strawberry jam. Stir thoroughly to coat all strawberries evenly.
05 - Spread half of the softened vanilla ice cream over the chilled crust, using an offset spatula to create an even layer.
06 - Distribute the strawberry mixture evenly over the ice cream layer, ensuring full coverage.
07 - Top with the remaining vanilla ice cream, smoothing the surface with a spatula for a flat, even top.
08 - Sprinkle the remaining cookie crumble evenly over the top surface. Gently press to adhere the crumbs to the ice cream.
09 - Cover tightly 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 using an electric mixer until stiff peaks form.
11 - Release the cake from the springform pan, top generously with whipped cream, and garnish with additional fresh strawberries if desired. Slice immediately and serve.
